Please answer this it was asked in interview , thanks in advance Smile

there are three tables
a. Emp_master b. Emp_dtl c. Error_log
update title column 'Mr.' in a table where gender = MALE
update state column 'Telangana' in b table where state = ANDAHRA
total records is 50,000 . So use loop
if any type of error comming anywhere in the transaction rollback for that employee
and create error_log in the the table.

i.e if no error then data will be in a table and b table
and if error then no data in a table and b table but oracle_error should be in error_log table so that we can check what type of error came for that record.

1/ Never do in PL/SQL what you can do in SQL, so no loop
2/ What is your answer? or what you try to answer the question?

Some suggestions:

Using the word "record" when you mean "row" would fail the interview, if I were in charge.
Question the use of PL/SQL rather than SQL (as MC said)
Look up the LOG ERRORS INTO clause of DML statements.

And just to do the Moderator bit:

Welcome to the forum. Please read our OraFAQ Forum Guide and How to use [code] tags and make your code easier to read

Certainly not. That would be fraudulent. Not many people want to employ criminals.

Most of us here are professionals. None of us would be willing to to help you cheat your way into a job that you're not qualified for. All that does is put added pressure on the department that you'd end up in, and take a job away from someone more capable than you.
