How to avoid no data found exception IN ORAcle?

When you are selecting INTO a variable and there are no records returned you should get a NO DATA FOUND error. I believe the correct way to write the above code would be to wrap the SELECT statement with it’s own BEGIN/EXCEPTION/END block.

Which exception is raised when a nonexistent data is fetched in PL SQL code?

An internal exception is raised automatically if your PL/SQL program violates an Oracle rule or exceeds a system-dependent limit. PL/SQL predefines some common Oracle errors as exceptions. For example, PL/SQL raises the predefined exception NO_DATA_FOUND if a SELECT INTO statement returns no rows.

How do I stop Ora-01403 No data found?

Action: Terminate processing for the SELECT statement. Many people experience ORA-01403 in association with the SELECT INTO clause. SELECT INTO clauses are standard SQL queries which pull a row or set of columns from a database, and put the retrieved data into variables which have been predefined.

What happens if an exception is raised in the program and that exception is not handled by an exception section in either the current or enclosing PL SQL blocks?

If an exception is raised in your program and that exception is not handled by an exception section in either the current or enclosing PL/SQL blocks, that exception is “unhandled.” PL/SQL returns the error which raised an unhandled exception all the way back to the application environment from which PL/SQL was run.

How do I fix Ora-01403 No data found?

To fix this, re-create tables from the initial controlling database. The good news is that the ORA-01403 error is highly preventable. By creating the proper exceptions, the program should now operate free of the error and remain that way until edited again.

How can we avoid buffer overflow error in Oracle?

Starting with Oracle release 10g, it is possible to use the following unlimited buffer settings:

1. PL/SQL: DBMS_OUTPUT. ENABLE (buffer_size => NULL);

How to avoid ora-01403 when no data is found?

Writing an exception that states “when NO_DATA_FOUND then return ‘No data in selected variable’”. By creating the proper exceptions, or at the least returning exceptions back to the proper calling block, the ORA-01403 can largely be skirted. There are some occasions where NOLOGGING clauses can also trigger an ORA-01403.

When does Oracle throw the no data found error?

Oracle throws the NO_DATA_FOUND error when a SELECT statement finds no data. So, looking at your trigger, the obvious explanation might be there is no data in your ROOM table. However, there is a subtle bug in your trigger code: select status into status_in from room where room.room_id = :old.room_id;

What does the error ” no data found ” mean?

The ORA-01403 error (“no data found”) is representative of this type of Oracle problem, and while it involves a bit more coding savvy than other errors, the fix tends to be much more long term. The ORA-01403 error derives from an SQL query meant to return all data requested, but no data was found. The error is often associated with SELECT INTO
