If you run "select * from stars where job_id='AD_PRE'" at the sql command line, does it return anything?

Stars table does neither have job_id nor job_title as fields, but you are using them in your prepared statement?
Include the update code in try catch block so you can see the exception thrown.

Oops! My apology. Thanks Mahesh.
Actually when I was unable to update data on stars table I was trying that code with jobs table but the result was same that means no updation happened to jobs table also. So when i was posting the code mistakenly I has copied the last code where jobs table was used.

Anyway I have modified the code for stars table using try catch block. Have a look:


The output is:
No. of rows updated: 0 Connection closed

Still its not working.

And you're absolutely sure there is a record in table "stars" with id 111111?
