A table-valued function, as the name implies, returns a table for the return value of the funct

It is important to note that the function name must be unique in the database, can have parameters, can have no parameters, and its parameters can only be input parameters, with a maximum of 1024 parameters.A

First, the conceptUser-defined exception errors are triggered by explicitly using the RAISE statement. When an exception error is thrown, the control moves to the exception block exception error section and executes the error-handling code.For handling this type of exception, the steps are as follows: In the declaration section of the PL/SQL block, define the exception condition: RAISE In the exception handling section of the PL/
