Over the past few weeks, some of our users have encountered a known error code while trying to troubleshoot oracle 10g. This problem is caused by many factors. Now we will discuss them.
Each oracle error has but a choice, exceptions must be handled because of the name. Therefore, PL/SQL predefines certain errors repeated by Oracle as exceptions. For example, PL/SQL throws the predefined NO_DATA_FOUND exception when SELECT INTO returns no rows. handling For other Oracle errors, you can use the OTHERS handler.
11.1 Warnings At Compile Time
When compiling PL/SQL stored entities, the PL/SQL compiler generates warnings for conditions that may not be severe enough to cause errors and prevent compilation, for example using a great deprecated PL/SQL function.
For warnings (and errors) generated at compile time, check the static data dictionary for
*_ERRORS or, in a SQL*Plus environment, even use the
SHOW command < code>ERROR.
How are unexpected error handled in Oracle?
To deal with unexpected Oracle failures, you can use other simulators. In this handler, you can use the SQLCODE and SQLERRM functions, which return an Oracle error code and a text message. Once you know this error code, you can use this type of EXCEPTION_INIT pragma and write an actual handler specifically for this error.
The PL/SQL warning message code is of the form PLW-nnnnn.
By setting the
PLSQL_WARNINGS collection option, you can:
Enable or disable all alerts, just one or several categories of alerts, possibly specific alerts
Treat some warnings as calls (so these conditions must be fixed before you can compile anyone’s PL/SQL module)
You must set the value of
How do you trace error handling?
Add a rollback error handler WHERE CREATE PROC3 REPLACE PROCEDURE BEGINS DBMS_OUTPUT. put_line(‘call process2; proc2’); IF exception THEN another DBMS_OUTPUT. put_line(‘Error returning upper level:’); SUBD_EXIT. put_line(DBMS_UTILITY.
Your Oracle Data Warehouse Instance
SYSTEM statement is used, which is fully documented in the Oracle Database SQL Language Reference.
