Pl Sql Exception Error Code


However, exceptions cannot propagate across remote procedure calls (RPCs). The other internal exceptions can be given names. VALUE_ERROR An arithmetic, conversion, truncation, or size-constraint error occurs. When the i_is_one exception handler raises ZERO_DIVIDE, the exception propagates immediately to the invoker (therefore, the ZERO_DIVIDE exception handler does not handle it). this page

NOT_LOGGED_ON 01012 -1012 It is raised when a database call is issued without being connected to the database. If you exit a stored subprogram with an unhandled exception, PL/SQL does not assign values to OUT parameters. SQLERRM returns the corresponding error message. If an error occurs in the sub-block, a local handler can catch the exception.

Oracle Raise Exception With Message

That lets you refer to any internal exception by name and to write a specific handler for it. LOOP -- could be FOR i IN 1..10 LOOP to allow ten tries BEGIN -- sub-block begins SAVEPOINT start_transaction; -- mark a savepoint /* Remove rows from a table of survey Entry point for handling errors. EXCEPTION WHEN NO_DATA_FOUND THEN -- catches all 'no data found' errors Instead of checking for an error at every point it might occur, just add an exception handler to your PL/SQL

In the following example, you pass positive numbers and so get unwanted results: DECLARE err_msg VARCHAR2(100); BEGIN /* Get all Oracle error messages. */ FOR err_num IN 1..9999 LOOP err_msg := Declaring PL/SQL Exceptions Exceptions can be declared only in the declarative part of a PL/SQL block, subprogram, or package. You can write handlers for predefined exceptions using the names in the following list: Exception Oracle Error SQLCODE Value ACCESS_INTO_NULL ORA-06530 -6530 CASE_NOT_FOUND ORA-06592 -6592 COLLECTION_IS_NULL ORA-06531 -6531 CURSOR_ALREADY_OPEN ORA-06511 -6511 Pl Sql Exception Handling Best Practices Retrying a Transaction After an exception is raised, rather than abandon your transaction, you might want to retry it.

For example, when your program selects a column value into a character variable, if the value is longer than the declared length of the variable, PL/SQL aborts the assignment and raises Pl Sql Exception Handling Examples Exceptions cannot propagate across remote procedure calls done through database links. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. https://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm So, a SELECT INTO statement that calls an aggregate function never raises NO_DATA_FOUND.

And so on down the line. Sqlerrm In Oracle These statements complete execution of the block or subprogram; control does not return to where the exception was raised. If the company has zero earnings, the predefined exception ZERO_DIVIDE is raised. The following example calculates a price-to-earnings ratio for a company.

ORA-01422 ZERO_DIVIDE When you attempt to divide a number by zero. https://www.techonthenet.com/oracle/exceptions/sqlerrm.php DECLARE Child_rec_exception EXCEPTION; PRAGMA EXCEPTION_INIT (Child_rec_exception, -2292); BEGIN Delete FROM product where product_id= 104; EXCEPTION WHEN Child_rec_exception THEN Dbms_output.put_line('Child records are present for this product_id.'); END; / c) User-defined Exceptions Apart Oracle Raise Exception With Message To use their values in a SQL statement, assign them to local variables first, as in Example 11-22. Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block So, PL/SQL predefines some common Oracle errors as exceptions.

Figure 10-1 Propagation Rules: Example 1 Description of the illustration lnpls009.gif Figure 10-2 Propagation Rules: Example 2 Description of the illustration lnpls010.gif Figure 10-3 Propagation Rules: Example 3 Description of the this website In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symbol XYZ. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. For example, in the Oracle Precompilers environment, any database changes made by a failed SQL statement or PL/SQL block are rolled back. Pl Sql Continue After Exception

SQL aggregate functions such as AVG and SUM always return a value or a null. ALTER PROCEDURE hello COMPILE PLSQL_WARNINGS='ENABLE:PERFORMANCE'; -- Recompile with extra checking. Examples of internally defined exceptions include division by zero and out of memory. http://back2cloud.com/pl-sql/pl-sql-error-exception-handling.php Instead, you must assign their values to local variables, then use the variables in the SQL statement, as shown in the following example: DECLARE err_msg VARCHAR2(100); BEGIN /* Get a few

PL/SQL declares predefined exceptions globally in package STANDARD, which defines the PL/SQL environment. Oracle Cursor Exception Handling Within A Loop If there is no handler for a user-defined exception, the calling application gets the following error: ORA-06510: PL/SQL: unhandled user-defined exception Reraising a PL/SQL Exception Sometimes, you want to reraise an Execution of the handler is complete, so the sub-block terminates, and execution continues with the INSERT statement.

BEGIN ---------- sub-block begins ...

Maximum salary is 10000. Associate the name with the error code of the internally defined exception. NOT_LOGGED_ON ORA-01012 Database connection lost. Exception No Data Found Oracle An exception raised inside a handler propagates immediately to the enclosing block, which is searched to find a handler for this new exception.

In the following example, if the SELECT INTO statement raises ZERO_DIVIDE, you cannot resume with the INSERT statement: DECLARE pe_ratio NUMBER(3,1); BEGIN DELETE FROM stats WHERE symbol = 'XYZ'; SELECT price Scope Rules for PL/SQL Exceptions You cannot declare an exception twice in the same block. But, if the need arises, you can use a locator variable to track statement execution, as follows: DECLARE stmt INTEGER := 1; -- designates 1st SELECT statement BEGIN SELECT ... see here If earnings are zero, the function DECODE returns a null.

VALUE_ERROR 06502 -6502 It is raised when an arithmetic, conversion, truncation, or size-constraint error occurs. more hot questions question feed lang-sql about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation The optional OTHERS handler catches all exceptions that the block does not name specifically. From there on, the exception propagates normally.

A cursor FOR loop automatically opens the cursor to which it refers, so your program cannot open that cursor inside the loop. DUP_VAL_ON_INDEX A program attempts to store duplicate THEN RAISE past_due; -- this is not handled END IF; END; ------------- sub-block ends EXCEPTION WHEN past_due THEN -- does not handle RAISEd exception ... These conditions are not serious enough to produce an error and keep you from compiling a subprogram. Table 11-3 lists the internally defined exceptions that have predefined names. "Internally Defined Exceptions" explains how to give user-declared names to internally defined exceptions.

You can, however, declare the same exception in two different blocks. You can avoid unhandled exceptions by coding an OTHERS handler at the topmost level of every PL/SQL program. into the errors table INSERT INTO errors (module, seq_number, error_stack, call_stack, timestamp) VALUES (p_Module, v_SeqNum, v_ErrorStack, v_CallStack, SYSDATE); /* Unwind the error stack to get Examples of internally defined exceptions include division by zero and out of memory.

RAISE_APPLICATION_ERROR Procedure You can invoke the RAISE_APPLICATION_ERROR procedure (defined in the DBMS_STANDARD package) only from a stored subprogram or method. If either ex_name_2 or ex_name_3 was raised, then statements_2 run. Once you know the error code, you can use it with pragma EXCEPTION_INIT and write a handler specifically for that error. 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 to
