EXECUTE

Function

EXECUTE executes a prepared statement. A prepared statement only exists in the lifecycle of a session. Therefore, only prepared statements created using PREPARE earlier in the session can be executed.

Precautions

If the PREPARE statement creating the prepared statement declares certain parameters, the parameter set transferred to the EXECUTE statement must be compatible. Otherwise, an error occurs.

Syntax

1

Parameter Description

• name

  Specifies the name of the statement to be executed.

• parameter

  Specifies a parameter of the prepared statement. It must be an expression that generates a value compatible with the data type specified when the prepared statement is created.
