There is a syntax error in the raise_application_error call in your trigger. That procedure takes two arguments, a number and a string. You are passing in a single argument that is one long string. create or replace trigger minimumwage before insert or update on Employee for each row begin if :new.Wage < 7.25 then raise_application_error(-20000,'Pay is below Texas minimum wage!'); end if; end; should be valid assuming there is a WAGE column in your EMPLOYEE table. share|improve this answer answered May 8 '13 at 20:06 Justin Cave 160k14204250 wow! oh my god D: thank you so much i was freaking out forever about it &nda

have to give specific exception conditions to handle the erros which are possible while dropping and adding partitions, or should I leave it by just oracle trigger raise application error giving the when others then exception, or should I leave it alone by not giving the exception section at all. what are the possible erros which can occur while trying to create a partition and trying to drop a partition. http://stackoverflow.com/questions/16449225/pl-sql-trigger-using-raise-application-error-thows-error 2. The use of pragma exception init is very clear, but Why do you have to use a raise application error. Can I just use a regular exception, and raise it when I require to. I dont see the specific use of raise application error. what is the advantage of raise application error over a regular exception which you declare in the exception section and use it. (the only advantage seems to be that you can assign a number(20001 to https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:1155066278457 20999) to the error.) correct me if Iam wrong. and we said... 1) A when others is almost always a BUG unless it is immediately followed by a RAISE. The point of an exception block is to catch exceptional conditions you are EXPECTING, handle them gracefully and continue. For example, lets say you have a procedure that will either INSERT a new record or UPDATE an existing one depending on whether or not it exists. You could code: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; end; Now, if that was coded: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; when others then null; end; that would be a bug. The when others would fire upon some spurious -- un-expected error and the record would be neither added nor updated. It would be skipped. Same with your routines, if you have a when others -- and don't do anything meaningful in it (eg: email yourself a notification that it failed, log a message using utl_file or an autonomous transaction, etc -- it is an error that will go undetected. I truly wish we didn't even support WHEN OTHERS. You should only catch the exc
program to continue to operate in the presence of errors.

An exception can be either internally defined (by the run-time system) or user-defined. Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (out of memory). Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define raise application error your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. User-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefin
