Pl Sql Sql Error Message

Each handler consists of a WHEN clause, which specifies an exception, followed by a sequence of statements to be executed when that exception is raised. Note that you do not need to qualify raise_application_error with DBMS_STANDARD */ raise_application_error(-20101, 'Expecting at least 1000 tables'); ELSE NULL; -- Do the rest of the processing (for the non-error case). Example 11-3 Single Exception Handler for Multiple Exceptions CREATE OR REPLACE PROCEDURE select_item ( t_column VARCHAR2, t_name VARCHAR2 ) AUTHID DEFINER IS temp VARCHAR2(30); BEGIN temp := t_column; -- For error v_End := INSTR(v_ErrorStack, v_NewLine, v_Index); -- The error is between the current index and the newline v_Error := SUBSTR(v_ErrorStack, v_Index, v_End - v_Index); -- Skip over the current click site

The error number and message can be trapped like any Oracle error. For example, if your SELECT statement returns multiple rows, TimesTen returns an error (exception) at runtime. If you are creating a procedure that can be called by name, use the CREATE OR REPLACE PROCEDURE syntax. Propagation of Exceptions Raised in Exception Handlers An exception raised in an exception handler propagates immediately to the enclosing block (or to the invoker or host environment if there is no check my blog

And so on down the line. At the level of the SQL*Plus prompt, every update/insert/delete has one implicit savepoint, and also the invocation of any unnamed block. oops:TT0907: Unique constraint (MYTABLE) violated at Rowid select * from mytable; 0 rows found.

But instead of the body definition shown there, consider the following, which defines hire_employee and num_above_salary but not remove_employee: CREATE OR REPLACE PACKAGE BODY emp_actions AS -- Code for procedure hire_employee: x x) has a type, then is the type system inconsistent? To call RAISE_APPLICATION_ERROR, use the syntax raise_application_error( error_number, message[, {TRUE | FALSE}]); where error_number is a negative integer in the range -20000 .. -20999 and message is a character string up Error-handling code is isolated in the exception-handling parts of the blocks.

Example 11-8 Redeclared Predefined Identifier DROP TABLE t; CREATE TABLE t (c NUMBER); In the following block, the INSERT statement implicitly raises the predefined exception INVALID_NUMBER, which the exception handler handles. So, only an OTHERS handler can catch the exception. Get each piece out for insertion. CASE 5: Then I deleted everything from the table 1 except the a1 = 1 and did a commit.

Was Sigmund Freud "deathly afraid" of the number 62? Place the statement in its own sub-block with its own exception handlers. 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 A PL/SQL block cannot catch an exception raised by a remote subprogram.

Example 11-15 Exception Raised in Declaration is Not Handled DECLARE credit_limit CONSTANT NUMBER(3) := 5000; -- Maximum value is 999 BEGIN NULL; EXCEPTION WHEN VALUE_ERROR THEN DBMS_OUTPUT.PUT_LINE('Exception raised in declaration.'); END; This avoids compilation errors. Do I need to do this? Sometimes you can use error-checking code to avoid raising an exception, as in Example 11-7.

END IF; END; / The calling application gets a PL/SQL exception, which it can process using the error-reporting functions SQLCODE and SQLERRM in an OTHERS handler. http://setiweb.org/pl-sql/pl-sql-exception-print-error-message.php Non-predefined TimesTen error Any other standard TimesTen error These must be declared in the declarative section of your application. Table 11-1 Compile-Time Warning Categories Category Description Example SEVERE Condition might cause unexpected action or wrong results. Use error-checking code wherever bad input data can cause an error.

Therefore, the values of explicit cursor attributes are not available in the handler. If you know that your database operations might raise specific internally defined exceptions that do not have names, then give them names so that you can write exception handlers specifically for If p_CommitFlag is TRUE, then the inserts are committed. http://setiweb.org/pl-sql/pl-sql-exception-get-error-message.php Example 11-6 Anonymous Block Handles ZERO_DIVIDE DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN pe_ratio := stock_price / net_earnings; -- raises ZERO_DIVIDE exception DBMS_OUTPUT.PUT_LINE('Price/earnings ratio = '

Otherwise we rollback to the top-level 'virtual' savepoint currently in existence, which is my offending unnamed block. Declaring PL/SQL Exceptions Exceptions can be declared only in the declarative part of a PL/SQL block, subprogram, or package. Finally, the example recompiles the procedure, and the compiler generates a warning about the unreachable code.

When I do a select for everything in the table a, I get the first row I inserted 'manually', the one with a1 = 1.

Below that, the unnamed block itself has 'sub' savepoints - one foreach insert/update/delete statement in it, and one for each subprogram unit. You can save the current state of the PLSQL_WARNINGS parameter with one call to the package, change the parameter to compile a particular set of subprograms, then restore the original parameter You need only include an exception-handling part in each block where errors might occur. unless you used the pragma EXCEPTION_INIT to associate the exception name with an Oracle error number, in which case SQLCODE returns that error number and SQLERRM returns the corresponding error message.

Consider using a cursor. Make your programs robust enough to work even if the database is not in the state you expect. You declare an exception by introducing its name, followed by the keyword EXCEPTION. http://setiweb.org/pl-sql/pl-sql-error-message-exception.php Why isn't tungsten used in supersonic aircraft?

The inner block raises exception A. INVALID_CURSOR Your program attempts an illegal cursor operation such as closing an unopened cursor. However, if you exit with an unhandled exception, PL/SQL does not assign values to OUT parameters (unless they are NOCOPY parameters). Scope Rules for PL/SQL Exceptions You cannot declare an exception twice in the same block.

In procedural statements, VALUE_ERROR is raised if the conversion of a character string into a number fails. (In SQL statements, INVALID_NUMBER is raised.) ZERO_DIVIDE 01476 -1476 A program attempts to divide Related Topics Anonymous Block DBMS_UTILITY DDL Triggers Instead-Of Triggers Errors Function Procedure System Events System Triggers Table Triggers UTL_LMS Warnings

Home : Code Library : Sponsors : Privacy Why don't browser DNS caches mitigate DDOS attacks on DNS providers? The other internal exceptions can be given names.

For example, in the Oracle Precompilers environment, any database changes made by a failed SQL statement or PL/SQL block are rolled back.
