EXECUTE

Function

EXECUTE executes a prepared statement. Because a prepared statement exists only in the lifetime of a session, the prepared statement must be created by an earlier PREPARE statement in the current session.

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

EXECUTE name [ ( parameter [, ...] ) ];

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.

EXECUTE insert_reason(52, 'AAAAAAAADDAAAAAA', 'reason 52');
