Pl Sql Exception Get Error Message
Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program. With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors. This chapter discusses the following topics: Overview of PL/SQL Error Handling Advantages of PL/SQL Exceptions Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Tips for Handling PL/SQL Errors Overview of PL/SQL Error Handling In PL/SQL, a warning or error condition is called an exception. Exceptions can be internally defined (by the run-time system) or user defined. Examples of internally defined exceptions include division by zero and 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 exceptions of your own 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. Unlike internal exceptions, 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, which can also raise predefined exceptions. To handle raised exceptions, you write separate routines calle
Error Handling" in Oracle Database PL/SQL Language Reference. See the end of this chapter for TimesTen-specific considerations. The following topics are covered: Understanding exceptions Trapping exceptions Showing errors in ttIsql Differences in TimesTen: exception handing and error behavior Understanding exceptions This section provides an overview of exceptions in PL/SQL programming, covering the following topics: About exceptions Exception types About exceptions An exception is a PL/SQL error that is raised during program execution, either implicitly by TimesTen or explicitly by your program. Handle an exception by trapping it https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm 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 messages, originally defined for Oracle Database, are similarly implemented by TimesTen.) Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN https://docs.oracle.com/cd/E11882_01/timesten.112/e21639/exceptions.htm > 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 include any standard TimesTen errors. User-defined exceptions are exceptions specific to your application. In TimesTen, these three types of exceptions are used in the same way as in Oracle Database.

I have one source, one target and one error table. Target and Error tables have pl sql all fields that are present in source tables. But the data type of all fields for error table are varchar. Error table don't have integrity, foreign key and other constraints. Error table also have two more fields: Error no and error message. Now when procedure is executed if there is error while inserting any record into target then that record shold be moved to error table. Also the data base error code and error message should be logged in the pl sql exception error tables fields as mentioned. How can i devlop such a procedure? Example of table schema: source table src(id number ,name varchar2(20) , ... ) target table tgt(id number ,name varchar2(20) not null , ... ) error table err (id varchar2(255) ,name varchar2(255) , ... , errno varchar2(255) , errmsg varchar2(255)) sql oracle error-handling plsql share|improve this question edited Dec 15 '09 at 12:31 APC 87.3k1384184 asked Dec 15 '09 at 9:25 user223541 39751028 What version of Oracle are you using? Also, could you explain whey you want to use such a horrible mechanism for loading data when Oracle provides several more elegant alternatives? –APC Dec 15 '09 at 13:00 If you question about logical errors in source data, not errors which can be detected by DBMS, look at MERGE statement, e.g. here: psoug.org/reference/merge.html –ThinkJet Dec 22 '09 at 15:52 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote Have you looked at Oracle's own error logging functionality? http://download.oracle.com/docs/cd/B19306%5F01/server.102/b14231/tables.htm#ADMIN10261 share|improve this answer edited Dec 15 '09 at 10:36 answered Dec 15 '09 at 9:52 David Aldridge 36.9k63866 David, I think you posted the wrong link - I can't see the relevance of this one? –Tony Andrews Dec 15 '09 at 10:11 Hmmm, strange.
