plsql show query

I have a small problem using oracle pl sql. I have a sql file with some cursor, etc, and the treatement fail but with no details. I have an idea about the problem (a function with parameters) but I would like to see the parameter for each call, to be able to debug, to see exactly with wich parameter fail. This is the message:

DECLARE
*
ERROR at line 1:
ORA-01422: exact fetch returns more than req开发者_运维技巧uested number of rows
ORA-06512: at line 165
ORA-06512: at line 260

Is there something to set to be able to see some details ?

I'm launching my treatement like this

sqlplus -L $ORA_CONNECT @$FIC_REQ 

This error occurs when you try to Select Into a variable, but your select returns more than one row.

Check these lines in your script:
165 and 260 (as displayed in the stacktrace of the error).

To output your parameters dbms_output should work. Test the following script:

Set Serveroutput On

Begin
  dbms_output.put_line('Test');
End;
