Plsql Error Handling Sqlerrm
Contents |
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 sqlerrm sqlcode errors meaningful to your PL/SQL program. With many programming languages, unless you disable error

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

Exceptions can be internally defined (by the run-time system) or user defined. Examples of internally sqlerrm line number 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 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. In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symbol XYZ. If the company has zero earnings, the predefined exception ZERO_DIVIDE is raised.

Term: SQLERRM Definition: In Oracle PL/SQL, SQLERRM is an error trapping function which returns the predefined error message corresponding to the input error number argument. If no argument has been provided, SQLERRM returns the error message associated with the last standard plsql error handling exception raised by the Oracle Server. It is defined in the Oracle STANDARD package. For user defined exceptions, SQLERRM returns the error message defined for an error number in PRAGMA EXCEPTION_INIT. If SQLERRM is invoked in the execution portion of the block, it returns "ORA-0000: normal, successful completion". Example Syntax: SQLERRM(Error Number) Example Usage: The PL/SQL block below raises ZERO_DIVIDE exception and displays the error message corresponding to error number -01476. DECLARE L_NUM1 NUMBER; L_NUM2 NUMBER; BEGIN L_NUM1 := 10; L_NUM2 := 0; DBMS_OUTPUT.PUT_LINE('RESULT:'||L_NUM1/L_NUM2); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('Exception Message:'||SQLERRM); END; / Exception Message:ORA-01476: divisor is equal to zero PL/SQL procedure successfully completed.

Oracle SQLERRM tips Oracle Database Tips by Burleson Consulting The Oracle SQLERRM function returns the error message associated with the most recently raised error exception. The Oracle SQLERRM function should only be used within the Exception Handling section of your PL/SQLcode: The Oracle docs note the syntax for the Oracle SQLERRM function as follows: sqlerrm_function ::=SQLERRM [(error_number)] You can capture error codes caused when a SQL statement raises an exception by using the Oracle SQLERRM globally-defined variablesOracle SQLERRM can help track exceptions that are handled by the OTHERS clauseof the exception handler. Oracle SQLERRM returns the error message from the current error code as shown below. Here is a working Oracle SQLERRM example: A value greater than 100 will raise an exception using the same function from the previous example. The exception handler caught the OTHERS clause and printed out the Oracle SQLERRM. Once error code has been identified, you can programmatically handle the exception: Oracle SQLERRM example 2: The error message of an error code can be retrieved by passing it to the SQLERRM procedure as like below. The error code -1403 is passed as an input to the SQLERRM procedure resulting in the appropriate error message as shown below, BEGIN dbms_output.put_line(sqlerrm(-1403)); END; Result: ORA-01403: no data found �� Burleson is the American Team Note: This Oracle documentation was created as a support and Oracle training reference for use by our DBA performance tuning consulting professionals.
