PL/SQL Execute Immediate and Error Trap Checking 

Expert Oracle Database Tips by Donald BurlesonNovember 22, 2015

Question:  I am using the PL/SQL execute immediate to generate dynamic SQL, but I don't know how to rap an error from dynamic SQL.  I know that it is important to check for any non zero error code from PL/SQL when sending SQL to the database for execution, but I don't know the syntax to check for error in a PL/SQL execute immediate statement.

Answer:  Inside PL/SQL you can trap and display any SQL error by testing the SQLCODE.  It is a best practice to always use the "when others" so that you trap any possible unexpected error from the execute immediate in your PL/SQL.

See my notes here, with working examples of execute immediate.

To trap an error when executing PL/SQL in a function or stored procedure, use the "when others" clause.

 In a single statement, you can trap a SQL error with execute immediate for both DML, DDL and SQL statements. Here we execute a DDL statement using execute immediate in PL/SQL and trap any non zero SQLCODE from the database:

execute immediate 'drop table TABLE1';
exception when others then null;

 In a PL/SQL cursor loop you can capture execute immediate errors like this:

for i in mycir loop
       execute immediate mystring (i);
       when others then myerror_proc  mymessage, sqlcode, sqlerrm)
end loop;  

Follow the link for more information on Late Binding and Runtime Binding in PL/SQL

For more information, see Dr. Hall's book on Advanced PL/SQL and download the working examples.
