code, check the Oracle Database trace files. The USER_DUMP_DEST initialization parameter specifies the current location of the trace files. You can find the value of this parameter by issuing SHOW PARAMETER USER_DUMP_DEST. For more information about trace files, see Oracle Database Performance Tuning Guide. Compile-Time Warnings While compiling stored PL/SQL units, the PL/SQL compiler generates warnings for conditions that are not serious enough to cause errors and pl sql exception when others prevent compilation—for example, using a deprecated PL/SQL feature. To see warnings (and errors) generated during compilation, either query the static data dictionary view *_ERRORS (described in Oracle Database Reference) or, in the SQL*Plus environment, use the command SHOW ERRORS. The message code of a PL/SQL warning has the form PLW-nnnnn. For the message codes of all PL/SQL warnings, see Oracle Database Error Messages. Table 11-1 summarizes the categories of warnings. Table 11-1 Compile-Time Warning Categories Category Description Example SEVERE Condition might cause unexpected action or wrong results. Aliasing problems with parameters PERFORMANCE Condition might cause performance problems. Passing a VARCHAR2 value to a NUMBER column in an INSERT statement INFORMATIONAL Condition does not affect performance or correctness, but you might want to change it to make the code more maintainable. Code that can never run By setting the compilation parameter PLSQL_WARNINGS, you can: Enable and disable all warnings, one or more categories of warnings, or specific warnings Treat specific warnings as errors (so that those conditions must be corrected before you can compile the PL/SQL unit) You can set the value of PLSQL_WARNINGS for: Your Oracle database instance Use the ALTER SYSTEM statement, described in Oracle Databas

Oracle sqlcode pl sql exception handling best practices = 100 tips Oracle Database Tips by Burleson Consulting April 1, 2015 Question: What is the sqlcode 100 in pl/sql raises an exception in which two of the following cases PL/SQL and what Oracle error is associated with sqlcode=100. Also, do I have to test for sqlcode=100 directly? Answer: The PL/SQL exception handler will about a PL/SQL program with a ORA-01403 error, https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm regardless of whether you test for sqlcode=100. The sqlcode=100 is the most common trapped error in PL/SQL, the "no data found" Boolean expression. For example, if the database returns a SQLCODE=100, the PL/SQL variable NO_DATA_FOUND will be set to TRUE.

From the Oracle documentation I understand that the error code is accompanied by an exception. What may be the reason behind this behaviour? The documentation says the error code 100 is DATA NOT FOUND; we have data for the select query. In this context does DATA NOT FOUND mean the select is failing or the lock is not available? Any help much appreciated. sql oracle exception locking share|improve this question edited Jan 13 '12 at 2:59 Andrew Russell 22837 asked Jan 11 '12 at 10:4
easiest fix would be is to handle the error in the PL/SQL block, When a SQL statement is written within a PL/SQL block, enclose the SQL with a BEGIN and END statement. Handle the exception and raise a user-friendly message or handle the rest of the processing. Eg: CREATE OR REPLACE PROCEDURE test_proc (p_empno IN NUMBER) IS l_empname VARCHAR2(50); BEGIN SELECT empname INTO l_empname FROM emp WHERE empno = p_empno; IF l_empname = 'Sarah Jones' THEN INSERT INTO empresult values ('105', 'Found Sarah Jones'); END IF; END; / The above procedure has not handled the error that would be raised if the select statement did not find the specified empno. See the following for the error raised: SQL> exec test_proc (1) begin test_proc (1); end; * ERROR at line 1: ORA-01403: no data found ORA-06512: at "TAROT.TEST_PROC", line 4 ORA-06512: at line 1 If you want the procedure to execute properly without errors on the screen, then you would have to handle the error. The Exception needs to be controlled by adding an exception handler to the code. The above code has been modified to handle an exception NO_DATA_FOUND. This is the name of the exception that the error relates to. CREATE OR REPLACE PROCEDURE test_proc (p_empno IN NUMBER) IS l_empname VARCHAR2(50); BEGIN SELECT empname INTO l_empname FROM emp WHERE empno = p_empno; IF l_empname = 'Sarah Jones' THEN INSERT INTO empresult values ('105', 'Found Sarah Jones'); END IF; EXCEPTION WHEN NO_DATA_FOUND THEN INSERT INTO empresult values(p_empno, 'Did not find Sarah Jones'); END; / If you execute the above procedure now, this is what you would see: SQL> exec test_proc (1) PL/SQL procedure successfully completed. SQL> select * 2 from empresult; EMPNO EMPNAME --------- -------------------------------------------------- 1 Did not find Sarah Jones As the exception was handled, a row was inserted into the empresult table with the error message you specified. When the exception is raised, the control jumps from the select statement to the exception handler routine. Any code after the Select will not get executed if an exception has been raised. But if you do have some code that needs to be executed after the select has been executed, irrespective of whether the select was successful or not, then you would need to nest the begin and end statements. CREATE OR REPLACE PROCEDURE test_proc (p_empno IN NUMBER) IS l_empname VARCHAR2(50); l_count NUMBER; BEGIN BEGIN SELECT empname INTO l_empname FROM emp WHERE empno = p_empno; IF l_empn
