TimesTen or explicitly by your program. Handle an exception by trapping it with a handler or propagating it to the calling environment. For example, if your SELECT statement returns multiple rows, TimesTen returns an error (exception) at runtime. As the following example shows, you would see TimesTen error 8507, then the associated ORA error message. (ORA pl/sql raises an exception in which two of the following cases messages, originally defined for Oracle Database, are similarly implemented by TimesTen.) Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN > SELECT last_name INTO v_lname > FROM employees > WHERE first_name = 'John'; > DBMS_OUTPUT.PUT_LINE ('Last name is :' || v_lname); > END; > / 8507: ORA-01422: exact fetch returns more than requested number of rows 8507: ORA-06512: at line 4 The command failed. You can handle such exceptions in your PL/SQL block so that your program completes successfully. For example: Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN > SELECT last_name INTO v_lname > FROM employees > WHERE first_name = 'John'; > DBMS_OUTPUT.PUT_LINE ('Last name is :' || v_lname); > EXCEPTION > WHEN TOO_MANY_ROWS THEN > DBMS_OUTPUT.PUT_LINE (' Your SELECT statement retrieved multiple > rows. Consider using a cursor.'); > END; > / Your SELECT statement retrieved multiple rows. Consider using a cursor. PL/SQL procedure successfully completed. Exception types There are three types of exceptions: Predefined exceptions are error conditions that are defined by PL/SQL. Non-predefined exceptions

How about putting it inside a PL/SQL anonymous block? BEGIN ... updates here ...

As you asked, my script will contain Update and Insert. for example, I may have 10-15 udpate queries and same amont of insert queries in same script file. Now I need to spool the result of each line of my script. is it possible? –Sabari Ram Mar 10 '14 at 2:15 DML inside a PL/SQL block does not cause the "x rows updated" type messages to be displayed. Instead, you can create your own messages and use dbms_output.put_line. –eaolson Mar 11 '14 at 3:42 How that can be done? am pretty new to this. –Sabari Ram Mar 11 '14 at 3:54 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and P

Join them; it only takes a minute: Sign up Make a PL/SQL stored procedure roll back all changes when an exception occurs? up vote 2 down vote favorite 1 I have a procedure that makes a number of updates to pl sql different tables. I want all of the changes to be rolled back should any error occur anywhere in the procedure. Therefore I utilized this structure: CREATE PROCEDURE foo (x NUMBER) IS BEGIN -- Do some inserts here. INSERT INTO bar VALUES (x); -- Sometimes there might be an error. IF x = 3 THEN RAISE_APPLICATION_ERROR(-20000, 'Wooops...'); END IF; EXCEPTION WHEN OTHERS THEN --Rollback all the changes and then raise the error again. ROLLBACK; RAISE; END foo; The problem pl sql exception is that this rolls back everything that has been done since the last commit, not just the changes made by the procedure. For instance, this will insert 4 and 5, but 1 and 2 will be rolled back: BEGIN FOR x IN 1..5 LOOP BEGIN foo(x); EXCEPTION WHEN OTHERS THEN NULL; END; END LOOP; END; How can I make the procedure roll back only the changes the procedure did during this call? I guess I should use transactions somehow, but I am not sure how to set it up. Please note that I want to fix this in the code for the procedure, and not in the code that calls it. oracle stored-procedures plsql transactions rollback share|improve this question asked Nov 25 '15 at 16:21 Anders 3,99752035 2 see oracle savepoint docs.oracle.com/cd/B19306_01/server.102/b14200/… –kevinsky Nov 25 '15 at 16:23 add a comment| 1 Answer 1 active oldest votes up vote 6 down vote accepted In Oracle you can use SAVEPOINTS. It would be this: CREATE PROCEDURE foo (x NUMBER) IS BEGIN SAVEPOINT update_bar; -- Do some inserts here. INSERT INTO bar VALUES (x); -- Sometimes there might be an error. IF x = 3 THEN RAISE_APPLICATION_ERROR(-20000, 'Wooops...'); END IF; EXCEPTION WHEN OTHERS THEN -- Rollback everything which was made after `SAVEPOINT update_bar` ROLLBACK TO update_bar; RAISE; END foo; share|improve this answer answered Nov 25 '15 at 16:40 Wernfried Domscheit 9,91521433 Do you
