FRM-40733 – PL/SQL Built-In DatabaseErrorCodeFailed

If you are getting the error message “FRM-40733 – PL/SQL built-in dbms_ErrorCodeFailed”, you need to understand the causes of this error. Most of these issues occur when SELECT INTO clauses fail, a character string is converted to a number, and the SELECT INTO statement returns no rows. You can use the SQLCODE function to return an error number when the SELECT INTO clause fails. In addition, you can also use this function in an IF statement to detect whether or not a particular query has a problem with the data in the table.

SELECT INTO clauses fail

PL/SQL errors thrown by the database can include several common SELECT INTO clause failures. This error is triggered by a number of reasons, such as: INVALID_NUMBER 01722 -1722 (invalid character string), LOGIN_DENIED 01012 -1012 (invalid credentials), NO_DATA_FOUND [100]], arithmetic or conversion error, or an invalid cursor operation.

SELECT INTO clauses in PL/SQL can produce this error code if they are executed on the wrong table. The SELECT INTO clause is designed to fetch data from a table into variables. If you use multiple columns, make sure the variable lists are compatible with each other. If your SELECT statement includes other clauses, such as INNER JOIN, GROUP BY, or UNION, it may result in more than one row being returned. If this happens, the error message will be thrown and you’ll need to make some changes to your database.

SQLCODE function returns error number

The SQLCODE function returns the error number associated with an exceptional situation. This function is only available in the exception handling section of a program. The syntax for the FRM-40733 error code is slightly different from that of Oracle. It requires no parameters or arguments and must be used in a code block that handles exceptions. If you encounter this error while working with a database, it is important to understand its pitfalls and the proper way to deal with it.

Exceptions can be of two types. System-defined exceptions are named exceptions and data-defined exceptions. Named exceptions are predefined and can be either a negative integer or a single character string. The error number is used when the SELECT INTO statement returns more rows than are expected. The error code also refers to a single row of data that contains zero or more values.

OTHERS clause

A common PL/SQL built-in that causes FRM-40733 is TABLE_FROM_BLOCK. This built-in can fetch block items’ names and values, or all records in a block. However, it is sometimes trapped by the FORM_SUCCESS keyword, and the execution proceeds to fail. In this case, the resulting error code FRM-40733 is the result.

The underlying reason for this error message is that the logic for the operation is incorrect. During trigger execution, the Built-in was not invoked properly, and the application is receiving a generic error message. To resolve this issue, you should review your application logic and try to determine whether the error is originating from the Built-in or from another cause. If you still encounter the error, contact Oracle Support Services.

SQLCODE can be used in IF statement

The IF statement can contain a SQLCODE to indicate that an error occurred. The error number will be a negative number for internal errors, and a positive one for user-defined errors. The SQLCODE function can be used only within an exception-handling statement; outside of the exception-handling section, it returns zero. The error number can be any valid Oracle error number. The SQLERRM function returns the error message associated with the current SQLCODE.

You can use the dbms_error_code function in an IF statement to detect a specific exception. It accepts no arguments and returns the number code of the most recent exception. You can use SQLCODE in an IF statement to test whether an error occurred or not.

Triggers

In the database, this error occurs during execution of a trigger in Oracle Forms. You can use triggers to show error messages and replace the visual representation of these messages. You can use the On-Error or On-Message triggers to catch this error. They intercept system messages and can also replace predefined error messages with custom messages.

The trigger is a statement that fires whenever a certain condition is met. During execution, it tries to access the triggering relation. It has a constraint on trigger_body, which prevents infinite loops. This is useful if you’ve used the foreign-key constraint. Otherwise, the error will occur only when the trigger is called.

Messages sent by built-in packages

You may encounter this problem when you try to send or receive a message. This error indicates that you are unable to send or receive a message through a built-in package. To solve the problem, you should check if the package is incompatible with the version of the messaging system you’re using. Generally, it’s not possible to use built-in packages for messages, because they don’t support this feature.
