45 Useful Oracle Queries

Here’s a list of 40+ Useful Oracle queries that every Oracle developer must bookmark. These queries range from date manipulation, getting server info, get execution status, calculate database size etc.

Date / Time related queries

  1. Get the first day of the month

    Quickly returns the first day of current month. Instead of current month you want to find first day of month where a date falls, replace SYSDATE with any date column/value.
    SELECT TRUNC (SYSDATE, 'MONTH') "First day of current month" 
        FROM DUAL;
    
  2. Get the last day of the month

    This query is similar to above but returns last day of current month. One thing worth noting is that it automatically takes care of leap year. So if you have 29 days in Feb, it will return 29/2. Also similar to above query replace SYSDATE with any other date column/value to find last day of that particular month.
    SELECT TRUNC (LAST_DAY (SYSDATE)) "Last day of current month" 
        FROM DUAL;
    
  3. Get the first day of the Year

    First day of year is always 1-Jan. This query can be use in stored procedure where you quickly want first day of year for some calculation.
    SELECT TRUNC (SYSDATE, 'YEAR') "Year First Day" FROM DUAL;
    
  4. Get the last day of the year

    Similar to above query. Instead of first day this query returns last day of current year.
    SELECT ADD_MONTHS (TRUNC (SYSDATE, 'YEAR'), 12) - 1 "Year Last Day" FROM DUAL
    
  5. Get number of days in current month

    Now this is useful. This query returns number of days in current month. You can change SYSDATE with any date/value to know number of days in that month.
    SELECT CAST (TO_CHAR (LAST_DAY (SYSDATE), 'dd') AS INT) number_of_days
      FROM DUAL;
    
  6. Get number of days left in current month

    Below query calculates number of days left in current month.
    SELECT SYSDATE,
           LAST_DAY (SYSDATE) "Last",
           LAST_DAY (SYSDATE) - SYSDATE "Days left"
      FROM DUAL;
    
  7. Get number of days between two dates

    Use this query to get difference between two dates in number of days.
    SELECT ROUND ( (MONTHS_BETWEEN ('01-Feb-2014', '01-Mar-2012') * 30), 0)
              num_of_days
      FROM DUAL;
    
    OR
    
    SELECT TRUNC(sysdate) - TRUNC(e.hire_date) FROM employees;
    
    Use second query if you need to find number of days since some specific date. In this example number of days since any employee is hired.
  8. Display each months start and end date upto last month of the year

    This clever query displays start date and end date of each month in current year. You might want to use this for certain types of calculations.
    SELECT ADD_MONTHS (TRUNC (SYSDATE, 'MONTH'), i) start_date,
           TRUNC (LAST_DAY (ADD_MONTHS (SYSDATE, i))) end_date
      FROM XMLTABLE (
              'for $i in 0 to xs:int(D) return $i'
              PASSING XMLELEMENT (
                         d,
                         FLOOR (
                            MONTHS_BETWEEN (
                               ADD_MONTHS (TRUNC (SYSDATE, 'YEAR') - 1, 12),
                               SYSDATE)))
              COLUMNS i INTEGER PATH '.');
    
  9. Get number of seconds passed since today (since 00:00 hr)

    SELECT (SYSDATE - TRUNC (SYSDATE)) * 24 * 60 * 60 num_of_sec_since_morning
      FROM DUAL;
    
  10. Get number of seconds left today (till 23:59:59 hr)

    SELECT (TRUNC (SYSDATE+1) - SYSDATE) * 24 * 60 * 60 num_of_sec_left
      FROM DUAL;
    

    Data dictionary queries

  11. Check if a table exists in the current database schema

    A simple query that can be used to check if a table exists before you create it. This way you can make your create table script rerunnable. Just replace table_name with actual table you want to check. This query will check if table exists for current user (from where the query is executed).
    SELECT table_name
      FROM user_tables
     WHERE table_name = 'TABLE_NAME';
    
  12. Check if a column exists in a table

    Simple query to check if a particular column exists in table. Useful when you tries to add new column in table using ALTER TABLE statement, you might wanna check if column already exists before adding one.
    SELECT column_name AS FOUND
      FROM user_tab_cols
     WHERE table_name = 'TABLE_NAME' AND column_name = 'COLUMN_NAME';
    
  13. Showing the table structure

    This query gives you the DDL statement for any table. Notice we have pass ‘TABLE’ as first parameter. This query can be generalized to get DDL statement of any database object. For example to get DDL for a view just replace first argument with ‘VIEW’ and second with your view name and so.
    SELECT DBMS_METADATA.get_ddl ('TABLE', 'TABLE_NAME', 'USER_NAME') FROM DUAL;
    
  14. Getting current schema

    Yet another query to get current schema name.
    SELECT SYS_CONTEXT ('userenv', 'current_schema') FROM DUAL;
    
  15. Changing current schema

    Yet another query to change the current schema. Useful when your script is expected to run under certain user but is actually executed by other user. It is always safe to set the current user to what your script expects.
    ALTER SESSION SET CURRENT_SCHEMA = new_schema;
    

    Database administration queries

  16. Database version information

    Returns the Oracle database version.
    SELECT * FROM v$version;
    
  17. Database default information

    Some system default information.
    SELECT username,
           profile,
           default_tablespace,
           temporary_tablespace
      FROM dba_users;
    
  18. Database Character Set information

    Display the character set information of database.
    SELECT * FROM nls_database_parameters;
    
  19. Get Oracle version

    SELECT VALUE
      FROM v$system_parameter
     WHERE name = 'compatible';
    
  20. Store data case sensitive but to index it case insensitive

    Now this ones tricky. Sometime you might querying database on some value independent of case. In your query you might do UPPER(..) = UPPER(..) on both sides to make it case insensitive. Now in such cases, you might want to make your index case insensitive so that they don’t occupy more space. Feel free to experiment with this one.
    CREATE TABLE tab (col1 VARCHAR2 (10));
    
    CREATE INDEX idx1
       ON tab (UPPER (col1));
    
    ANALYZE TABLE a COMPUTE STATISTICS;
    
  21. Resizing Tablespace without adding datafile

    Yet another DDL query to resize table space.
    ALTER DATABASE DATAFILE '/work/oradata/STARTST/STAR02D.dbf' resize 2000M;
    
  22. Checking autoextend on/off for Tablespaces

    Query to check if autoextend is on or off for a given tablespace.
    SELECT SUBSTR (file_name, 1, 50), AUTOEXTENSIBLE FROM dba_data_files;
    
    (OR)
    
    SELECT tablespace_name, AUTOEXTENSIBLE FROM dba_data_files;
    
  23. Adding datafile to a tablespace

    Query to add datafile in a tablespace.
    ALTER TABLESPACE data01 ADD DATAFILE '/work/oradata/STARTST/data01.dbf'
        SIZE 1000M AUTOEXTEND OFF;
    
  24. Increasing datafile size

    Yet another query to increase the datafile size of a given datafile.
    ALTER DATABASE DATAFILE '/u01/app/Test_data_01.dbf' RESIZE 2G;
    
  25. Find the Actual size of a Database

    Gives the actual database size in GB.
    SELECT SUM (bytes) / 1024 / 1024 / 1024 AS GB FROM dba_data_files;
    
  26. Find the size occupied by Data in a Database or Database usage details

    Gives the size occupied by data in this database.
    SELECT SUM (bytes) / 1024 / 1024 / 1024 AS GB FROM dba_segments;
    
  27. Find the size of the SCHEMA/USER

    Give the size of user in MBs.
    SELECT SUM (bytes / 1024 / 1024) "size"
      FROM dba_segments
     WHERE owner = '&owner';
    
  28. Last SQL fired by the User on Database

    This query will display last SQL query fired by each user in this database. Notice how this query display last SQL per each session.
    SELECT S.USERNAME || '(' || s.sid || ')-' || s.osuser UNAME,
             s.program || '-' || s.terminal || '(' || s.machine || ')' PROG,
             s.sid || '/' || s.serial# sid,
             s.status "Status",
             p.spid,
             sql_text sqltext
        FROM v$sqltext_with_newlines t, V$SESSION s, v$process p
       WHERE     t.address = s.sql_address
             AND p.addr = s.paddr(+)
             AND t.hash_value = s.sql_hash_value
    ORDER BY s.sid, t.piece;
    

    Performance related queries

  29. CPU usage of the USER

    Displays CPU usage for each User. Useful to understand database load by user.
    SELECT ss.username, se.SID, VALUE / 100 cpu_usage_seconds
        FROM v$session ss, v$sesstat se, v$statname sn
       WHERE     se.STATISTIC# = sn.STATISTIC#
             AND NAME LIKE '%CPU used by this session%'
             AND se.SID = ss.SID
             AND ss.status = 'ACTIVE'
             AND ss.username IS NOT NULL
    ORDER BY VALUE DESC;
    
  30. Long Query progress in database

    Show the progress of long running queries.
    SELECT a.sid,
             a.serial#,
             b.username,
             opname OPERATION,
             target OBJECT,
             TRUNC (elapsed_seconds, 5) "ET (s)",
             TO_CHAR (start_time, 'HH24:MI:SS') start_time,
             ROUND ( (sofar / totalwork) * 100, 2) "COMPLETE (%)"
        FROM v$session_longops a, v$session b
       WHERE     a.sid = b.sid
             AND b.username NOT IN ('SYS', 'SYSTEM')
             AND totalwork > 0
    ORDER BY elapsed_seconds;
    
  31. Get current session id, process id, client process id?

    This is for those who wants to do some voodoo magic using process ids and session ids.
    SELECT b.sid,
           b.serial#,
           a.spid processid,
           b.process clientpid
      FROM v$process a, v$session b
     WHERE a.addr = b.paddr AND b.audsid = USERENV ('sessionid');
    
    • V$SESSION.SID AND V$SESSION.SERIAL# is database process id
    • V$PROCESS.SPID is shadow process id on this database server
    • V$SESSION.PROCESS is client PROCESS ID, ON windows it IS : separated THE FIRST # IS THE PROCESS ID ON THE client AND 2nd one IS THE THREAD id.
  32. Last SQL Fired from particular Schema or Table:

    SELECT CREATED, TIMESTAMP, last_ddl_time
      FROM all_objects
     WHERE     OWNER = 'MYSCHEMA'
           AND OBJECT_TYPE = 'TABLE'
           AND OBJECT_NAME = 'EMPLOYEE_TABLE';
    
  33. Find Top 10 SQL by reads per execution

    SELECT *
      FROM (  SELECT ROWNUM,
                     SUBSTR (a.sql_text, 1, 200) sql_text,
                     TRUNC (
                        a.disk_reads / DECODE (a.executions, 0, 1, a.executions))
                        reads_per_execution,
                     a.buffer_gets,
                     a.disk_reads,
                     a.executions,
                     a.sorts,
                     a.address
                FROM v$sqlarea a
            ORDER BY 3 DESC)
     WHERE ROWNUM < 10;
    
  34. Oracle SQL query over the view that shows actual Oracle connections.

    SELECT osuser,
             username,
             machine,
             program
        FROM v$session
    ORDER BY osuser;
    
  35. Oracle SQL query that show the opened connections group by the program that opens the connection.

        FROM v$session
    GROUP BY program
    ORDER BY Numero_Sesiones DESC;
    
  36. Oracle SQL query that shows Oracle users connected and the sessions number for user

    SELECT username Usuario_Oracle, COUNT (username) Numero_Sesiones
        FROM v$session
    GROUP BY username
    ORDER BY Numero_Sesiones DESC;
    
  37. Get number of objects per owner

    SELECT owner, COUNT (owner) number_of_objects
        FROM dba_objects
    GROUP BY owner
    ORDER BY number_of_objects DESC;
    

    Utility / Math related queries

  38. Convert number to words

    SELECT TO_CHAR (TO_DATE (1526, 'j'), 'jsp') FROM DUAL;
    
    Output:
    one thousand five hundred twenty-six
    
  39. Find string in package source code

    Below query will search for string ‘FOO_SOMETHING’ in all package source. This query comes handy when you want to find a particular procedure or function call from all the source code.
    --search a string foo_something in package source code
    SELECT *
      FROM dba_source
     WHERE UPPER (text) LIKE '%FOO_SOMETHING%' 
    AND owner = 'USER_NAME';
    
  40. Convert Comma Separated Values into Table

    The query can come quite handy when you have comma separated data string that you need to convert into table so that you can use other SQL queries like IN or NOT IN. Here we are converting ‘AA,BB,CC,DD,EE,FF’ string to table containing AA, BB, CC etc. as each row. Once you have this table you can join it with other table to quickly do some useful stuffs.
    WITH csv
         AS (SELECT 'AA,BB,CC,DD,EE,FF'
                       AS csvdata
               FROM DUAL)
        SELECT REGEXP_SUBSTR (csv.csvdata, '[^,]+', 1, LEVEL) pivot_char
          FROM DUAL, csv
    CONNECT BY REGEXP_SUBSTR (csv.csvdata,'[^,]+', 1, LEVEL) IS NOT NULL;
    
  41. Find the last record from a table

    This ones straight forward. Use this when your table does not have primary key or you cannot be sure if record having max primary key is the latest one.
    SELECT *
      FROM employees
     WHERE ROWID IN (SELECT MAX (ROWID) FROM employees);
    
    (OR)
    
    SELECT * FROM employees
    MINUS
    SELECT *
      FROM employees
     WHERE ROWNUM < (SELECT COUNT (*) FROM employees);
    
  42. Row Data Multiplication in Oracle

    This query use some tricky math functions to multiply values from each row. Read below article for more details.
    More info: Row Data Multiplication In Oracle
    WITH tbl
         AS (SELECT -2 num FROM DUAL
             UNION
             SELECT -3 num FROM DUAL
             UNION
             SELECT -4 num FROM DUAL),
         sign_val
         AS (SELECT CASE MOD (COUNT (*), 2) WHEN 0 THEN 1 ELSE -1 END val
               FROM tbl
              WHERE num < 0)
      SELECT EXP (SUM (LN (ABS (num)))) * val
        FROM tbl, sign_val
    GROUP BY val;
    
  43. Generating Random Data In Oracle

    You might want to generate some random data to quickly insert in table for testing. Below query help you do that. Read this article for more details.
    More info: Random Data in Oracle
    SELECT LEVEL empl_id,
               MOD (ROWNUM, 50000) dept_id,
               TRUNC (DBMS_RANDOM.VALUE (1000, 500000), 2) salary,
               DECODE (ROUND (DBMS_RANDOM.VALUE (1, 2)),  1, 'M',  2, 'F') gender,
               TO_DATE (
                     ROUND (DBMS_RANDOM.VALUE (1, 28))
                  || '-'
                  || ROUND (DBMS_RANDOM.VALUE (1, 12))
                  || '-'
                  || ROUND (DBMS_RANDOM.VALUE (1900, 2010)),
                  'DD-MM-YYYY')
                  dob,
               DBMS_RANDOM.STRING ('x', DBMS_RANDOM.VALUE (20, 50)) address
          FROM DUAL
    CONNECT BY LEVEL < 10000;
    
  44. Random number generator in Oracle

    Plain old random number generator in Oracle. This ones generate a random number between 0 and 100. Change the multiplier to number that you want to set limit for.
    --generate random number between 0 and 100
    SELECT ROUND (DBMS_RANDOM.VALUE () * 100) + 1 AS random_num FROM DUAL;
    
  45. Check if table contains any data

    This one can be written in multiple ways. You can create count(*) on a table to know number of rows. But this query is more efficient given the fact that we are only interested in knowing if table has any data.
    SELECT 1
      FROM TABLE_NAME
     WHERE ROWNUM = 1;
    
If you have some cool query that can make life of other Oracle developers easy, do share in comment section.

My XI against WI for 3rd Test Match

Rohit Sharma, Bhuvneshwar Kumar and Stuart Binny released from Indian squad

It doesn't make sense playing Stuart ahead of Bhuvneshwar. Bhuvi is a far far better bowler than Binny in terms of control, wicket taking capability and he has added extra 8-12 kms speed in his bowling as well. I am ready to accept Stuart has a slight advantage in batting. Bhuvi is not a tail under either. Lets assume if Stuart scores 20 points in batting Bhuvi will get 19 at least. So for me Bhuvneshwar should be playing ahead of Binny in all matches. Binny swings the bowl but we all know Bhuvi is an out-and-out swing bowler.

Umesh has pace but not the maturity or resilience or wicket taking capability as Bhuvi. So Bhuvi should play ahead of him in XI.

Pujara is great batsman but needs some time off. And Ravindra needs a game as well. We saw how well he bowled in the second practice match. So my playing XI against WI for 3rd test would be ..

1. M Vijay 2. KLRahul 3. Shikhar Dhawan 4. Virat Kohli 5. Ajinkya Rahane 6. R Ashwin 7. Wriddhiman Saha 8. Ravindra Jadeja 9. Bhuvneshwar Kumar 10. Mohammed Shami 11. Ishant Sharma

England Squad for 2nd test


2nd Investec Test: England v Pakistan at Manchester
Jul 22-26, 2016 (11:00 local | 10:00 GMT | 11:00 IST)


In my views, England and Trevor should consider batting James as opener. Bring Joe back to familiar 2nd down, where he is most successful and more importantly comfortable. Straight swap between Adil and Moeen. Play Alex at first drop. I wanted another batsmen instead of Gary and Alex, especially Gary but as no spare batsmen available in XIV, will have to stick to these 2 guys.

So my final XI would be :
1. Alastair Cook, 2. James Vince, 3. Alex Hales, 4. Joe Root, 5. Jonny Bairstow, 6. Gary Ballance, 7. Ben Stokes, 8. Chris Woakes, 9. Adil Rasheed, 10. Stuart Broad, 11. James Anderson

I know its not gonna happen.
But if you see we have 7 pure batsmen (including Ben, he is no less). 4 quality seamers (including Ben again) including in form Chris and one leg-spinner who could bat as well. May be, we are past prime of Stuart's (batting) but he has few good days left. Only James is a specialist no 11. All others can bat. We could get few partnership-breadking overs from Joe and James. Personally, I would like to have see a better wicket-keeper. Nonetheless Jonny would have kept his place a specialist batter. He has shown enough. In that case, straight swap for Gary to Wicket-keeper. And my XI would have looked like :


1. Alastair Cook, 2. James Vince, 3. Alex Hales, 4. Joe Root, 5. Jonny Bairstow, 6Ben Stokes, 7. Chris Woakes, 8. Wicket-keeper 9. Adil Rasheed, 10. Stuart Broad, 11. James Anderson

England and Trevor should think about it.

WhatsApp New Font Tricks






Since the day, Facebook acquired Whatsapp, small innovations are on our way. Facebook has a history of rolling out updated without much fanfare.

If we want to change look of our WhatsApp messages there's a simple trick. New font - called FixedSys - can by activated for a particular chat text by adding 3 times (`) character (without brackets) before and after our message.

Example : ```How are you doing today?```

I have tried it can confirm by firsthand experience it works.



Image Needed






Old Text Formatting Already Available in Whatsapp :

Last time Facebook enabled us to write in bold and italics. Add asterisk (*) either side of text in a particular chat text to bolden it and underscore (_) to italicize.

Example : *bold* will be bold and _italic_ will be italic.

Prisma App Now Available For Android! Is it the Most Disruptive Image Effects App?


If you think that PicsArt, Instagram, and Retrica are of the best apps that let you add superb effects via filters to your photos then think again. And if you think that having a logo of Retrica on your photos makes you look cool, then be prepared to be surprised.

All of the image retouching apps that you are familiar with are about to get a major setback soon with the launch of Prisma for Android. The app has been available for iOS for a quite some time now, but it is now available in beta for Android devices as well.

What’s the big fuss about Prisma?
Now that you know how excited I am about this app, let’s see what makes this app worth so much hype. According to the Prisma official website, the app will let you transform your photos into artworks. The app uses the styles of various popular artists likePicasso, Van Gogh, and Levitan along with retouching the photos of your priceless moments using various new filters.

Prisma achieves this using a unique combination of neural networks and AI (artificial intelligence) for producing mind-blowing results.

How To Get Prisma Android App?
As of now, Prisma is only available for iOS devices on the App Store, with no way to download via Google Play, but you can sign up for News on Prisma’s official website and the developers will you send an invite link.

You can also download Prisma apk from here and dive into the world of Prisma.

How To Use Prisma?
When you open the app, you can start either by clicking a new photo (including selfies), or by selecting an image from the gallery. However, the app offers no controls over the camera but the LED flash.

Note: An internet connection is needed for applying the filters in Prisma.

Just open the camera via the Prisma app, click a picture, select a filter of your choice, and share it among your friends.

If you want to retouch an already clicked picture then follow the procedure below:
Touch the thumbnail on the bottom-right corner of the screen and select the image that you want to apply the filters to.
Change the orientation, crop the image, and click next.
Select the filter that you want to apply, and drag your finger horizontally on the image to adjust the intensity of the effect and…
You’re good to go.

In this version, Prisma won’t show you an option to save your artwork once it’s done retouching. You can only share your image via Instagram and other standard sharing options. However, there is an option to ‘Save artworks automatically’ in the Settings menu. If you enable that then you need not worry about saving your masterpieces created via Prisma.



All these automatically saved artworks are saved to Prisma’s folder which can be accessed by going to File manager -> Prisma

As of now, Prisma allows you to choose from 36 filters for retouching your images, but as already mentioned you need internet access for doing so. If you are on a mobile data connection then you should know that Prisma uses a lot of data.
Some Examples






During my initial testing, Prisma used more than 8 MB of data for converting just nine 13 MP images into square artworks (1:1 aspect ratio). This is a huge volume of data especially when you are on a mobile data plan with limited usage of 1 GB or so.

Also the image transformation takes somewhere between 5-10 seconds (sometimes even more) which is too slow when you are in a hurry to share that scenic vista on social networks.

I do hope that Prisma will get faster and data efficient by the time of its full launch on Google Play. Download the Prisma app fromhere and give it try. Do you think it is best image retouching app out there?

Never buy Lenovo Mobiles going forth



Guys

What do we look before buying a smartphone? Specs, price mainly, correct?
Believe me start considering service centers as well. Even I would say SERVICE should be first priority.

I had bought a Lenovo K3 Note last year. We all know it was a huge success and was top selling smartphone. As it was budget phone costing Rs 9,999 only and applying some offers, I myself had to pay somewhere around Rs 9,200. It packed high level specs in 5.5 inch mobile.

But its a failure. All the friends and family using this phone has reported same thing. And if you do not believe me, visit any Lenovo MOBILE Service Center (Please be certain to visit MOBILE service center and not Laptop/Tablet). You will find long waiting queues.

There is huge shift in approach for Lenovo Mobile Handsets. Even if a small nail scratch gets on Lenovo phone screen, whole warranty will be void. I had visited B2X Lenovo Mobiles Service Center and it was a very bad experience. Though I am not very sure, if it is same with all the Lenovo Service Centers. And it wasn't only me. There were several other surprised and unsatisified customers. I am yet to visit another Lenovo Service Center 

Bottom line is if your lenovo handset has even a very small scratch, they will say warranty is void. And phone can only be serviced if you accept to pay the charges.

P.S, - Motorolla has been acquired by Lenovo around 2 years back. And Lenovo service centers cater needs of Motorolla phones as well. Need to check, what's their status.
