Pl Sql Error Codes


SUBSCRIPT_OUTSIDE_LIMIT ORA-06532 Reference to a nested table or varray index outside the declared range (such as -1). Consider the following example: BEGIN DECLARE ---------- sub-block begins past_due EXCEPTION; due_date DATE := trunc(SYSDATE) - 1; todays_date DATE := trunc(SYSDATE); BEGIN IF due_date < todays_date THEN RAISE past_due; END IF; This parameter can be set at the system level or the session level. You can enable and disable entire categories of warnings (ALL, SEVERE, INFORMATIONAL, PERFORMANCE), enable and disable specific message numbers, and make the database treat certain warnings as compilation errors so that

Unhandled exceptions can also affect subprograms. This is shown in Example 4-4. To reraise an exception, simply place a RAISE statement in the local handler, as shown in the following example: DECLARE out_of_balance EXCEPTION; BEGIN ... If there is no enclosing block, control returns to the host environment.

Pl Sql Exception Handling Examples

SYS_INVALID_ROWID The conversion of a character string into a universal rowid fails because the character string does not represent a valid rowid. In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symbol XYZ. Errors can also arise from problems that are independent of your code—for example, disk storage or memory hardware failure—but your code still must take corrective action. Thus, the RAISE statement and the WHEN clause refer to different exceptions.

Retrieving the Error Code and Error Message: SQLCODE and SQLERRM In an exception handler, you can use the built-in functions SQLCODE and SQLERRM to find out which error occurred and to You can find the value of this parameter by issuing SHOW PARAMETER USER_DUMP_DEST. All rights reserved. Pl/sql Raises An Exception In Which Two Of The Following Cases RAISE_APPLICATION_ERROR is used for the following reasons, a) to create a unique id for an user-defined exception.

Passing a positive number to SQLERRM always returns the message user-defined exception unless you pass +100, in which case SQLERRM returns the message no data found. Handling Exceptions Raised in Handlers When an exception occurs within an exception handler, that same handler cannot catch the exception. You can also perform a sequence of DML operations where some might fail, and process the exceptions only after the entire operation is complete, as described in "Handling FORALL Exceptions with https://docs.oracle.com/cd/B13789_01/appdev.101/b10807/07_errs.htm The message code of a PL/SQL warning has the form PLW-nnnnn.

ROWTYPE_MISMATCH ORA-06504 -6504 Host cursor variable and PL/SQL cursor variable involved in an assignment statement have incompatible return types. Oracle Sqlerrm You can avoid such problems by declaring individual variables with %TYPE qualifiers, and declaring records to hold query results with %ROWTYPE qualifiers. Because this exception is used internally by some SQL functions to signal that they are finished, you should not rely on this exception being propagated if you raise it within a This will be after the first occurrence of 'name' and the newline. */ v_Index := INSTR(v_CallStack, 'name') + 5; /* Loop through the string, finding each newline.

Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block

Examples of internally defined exceptions include division by zero and out of memory. https://www.techonthenet.com/oracle/exceptions/sqlerrm.php How can I handle it? Pl Sql Exception Handling Examples VALUE_ERROR An arithmetic, conversion, truncation, or size-constraint error occurs. Oracle Raise Exception With Message SUBSCRIPT_OUTSIDE_LIMIT Your program references a nested table or varray element using an index number (-1 for example) that is outside the legal range.

The general syntax to declare unnamed system exception using EXCEPTION_INIT is: DECLARE exception_name EXCEPTION; PRAGMA EXCEPTION_INIT (exception_name, Err_code); BEGIN Execution section EXCEPTION WHEN exception_name THEN handle the exception END; For Example: If you want execution to resume with the INSERT statement that follows the SELECT INTO statement, then put the SELECT INTO statement in an inner block with its own ZERO_DIVIDE exception If the INSERT succeeds, we exit from the loop immediately.

Pl Sql Exception Handling Best Practices

Performance: Messages for conditions that might cause performance problems, such as passing a VARCHAR2 value to a NUMBER column in an INSERT statement. PL/SQL Exception message consists of three parts. 1) Type of Exception 2) An Error Code 3) A message By Handling the exceptions we can ensure a PL/SQL block does not exit Raising Exceptions with the RAISE Statement PL/SQL blocks and subprograms should raise an exception only when an error makes it undesirable or impossible to finish processing. NO_DATA_FOUND ORA-01403 +100 Single row SELECT returned no rows or your program referenced a deleted element in a nested table or an uninitialized element in an associative array (index-by table).

Defining Your Own PL/SQL Exceptions PL/SQL lets you define exceptions of your own. Which Of The Following Is Not A Type Of Pl/sql Exception You can make the checking as general or as precise as you like. THEN -- handle the error WHEN ...

You can handle such exceptions in your PL/SQL block so that your program completes successfully. go

PSOUG Home Code Snippets Oracle Lookup Oracle Reference Oracle Error Codes Oracle Functions PSOUG Forum CODE Oracle Code Library JOBS Find Or Post Oracle Jobs FORUM Oracle Discussion & To work with PL/SQL warning messages, you use the PLSQL_WARNINGS initialization parameter, the DBMS_WARNING package, and the USER/DBA/ALL_PLSQL_OBJECT_SETTINGS views. How Can We Handle Errors In Pl Sql The outer block declares the exception, so the exception name exists in both blocks, and each block has an exception handler specifically for that exception.

Reraising the exception passes it to the enclosing block, which can handle it further. (If the enclosing block cannot handle the reraised exception, then the exception propagates—see "Exception Propagation".) When reraising From there on, the exception propagates normally. Oracle recommends using DBMS_UTILITY.FORMAT_ERROR_STACK, except when using the FORALL statement with its SAVE EXCEPTIONS clause, as in Example 12-13. Exceptions declared in a block are considered local to that block and global to all its sub-blocks.

BEGIN * ERROR at line 1: ORA-01476: divisor is equal to zero ORA-06512: at "HR.DESCENDING_RECIPROCALS", line 19 ORA-06510: PL/SQL: unhandled user-defined exception ORA-06512: at line 2 Example 11-21 is like Example Declaring PL/SQL Exceptions Exceptions can be declared only in the declarative part of a PL/SQL block, subprogram, or package. TIMEOUT_ON_RESOURCE A time-out occurs while Oracle is waiting for a resource. 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.

The command succeeded. Consider the following example: BEGIN ... When I do a select for everything in the table a, I get the first row I inserted 'manually', the one with a1 = 1. Steps to be followed to use unnamed system exceptions are • They are raised implicitly. • If they are not handled in WHEN Others they must be handled explicity. • To

TOO_MANY_ROWS A SELECT INTO statement returns more than one row. WHEN OTHERS THEN -- handles all other errors ROLLBACK; END; -- exception handlers and block end here The last example illustrates exception handling, not the effective use of INSERT statements. As the following example shows, use of the OTHERS handler guarantees that no exception will go unhandled: EXCEPTION WHEN ... In Example 11-3, a procedure uses a single exception handler to handle the predefined exception NO_DATA_FOUND, which can occur in either of two SELECT INTO statements.

pe_ratio := stock_price / net_earnings; dbms_output.put_line('Price/earnings ratio = ' || pe_ratio); EXCEPTION -- exception handlers begin -- Only one of the WHEN blocks is executed. The syntax for declaring an exception is: DECLARE my-exception EXCEPTION; Example: The following example illustrates the concept. By associating the exception code to a name and using it as a named exception. Internally Defined Exceptions Internally defined exceptions (ORA-n errors) are described in Oracle Database Error Messages.
