Disable No_Data_Found Exception in Pl-SQL block

Posted on 2014-07-19
Last Modified: 2014-07-21

In my Pl-SQL block there are 20 different SELECT queries extracting data from different tables.  And the requirement is that all queries are independent to each other, means that if any SQL statement gives error the procedure should continue for next SELECT statement instead of STOPPING procedure at EXCEPTION level.  I know that we can use BEGIN and END for each independent query to call its own EXCEPTION block.  But is there any way to disable NO__DATA_FOUND exception for the said PL/SQL block so all the queries run continuously without using their separate BEGIN and END block.

Thanks and Regards,

You could try adding a dummy column at the end of each select that selects some string from dual. That way you always get a record from the select (but filled with one or more NULLs).

Like this:

before: select a,b,c from d;
after: select a,b,c, (select 'some_string' d from dual) from d;

Nested pl/sql blocks with their own exception handler is the correct way to do this.

Yes, I know about that but the queries are too much so NESTED pl/sql block makes the code complex so I want to ask, if there is any way to disable any exception in PL/SQL block

I do not know of a way to disable exceptions for an entire block of code.

I feel you will either need to edit the code and do things the way they are supposed to be done or edit the selects as suggested above so they always return something.

One way is to go for the count..

first count the record set output of the query, if its greater than 0(obviously if 0 means no data found) then you can execute the query..

But here you have to write a statement again which is simply a duplicate of actual query where in its just checking the count.

as experts suggested.. nested pl/sql blocks are the efficient way to do this..
