NAME
       EXECUTE - execute a prepared statement


SYNOPSIS
       EXECUTE plan_name [ (parameter [, ...] ) ]


DESCRIPTION
       EXECUTE is used to execute a previously prepared statement. Since pre-
       pared statements only exist for the duration of a  session,  the	 pre-
       pared statement must have been created by a PREPARE statement executed
       earlier in the current session.

       If the PREPARE statement that created  the  statement  specified	 some
       parameters,  a compatible set of parameters must be passed to the EXE-
       CUTE statement, or else an error is raised. Note	 that  (unlike	func-
       tions)  prepared	 statements  are  not overloaded based on the type or
       number of their parameters; the name of a prepared statement  must  be
       unique within a database session.

       For more information on the creation and usage of prepared statements,
       see PREPARE [prepare(7)].

PARAMETERS
       plan_name
	      The name of the prepared statement to execute.

       parameter
	      The actual value of a parameter to the prepared statement. This
	      must  be	an  expression	yielding a value of a type compatible
	      with the data type specified for this parameter position in the
	      PREPARE command that created the prepared statement.

COMPATIBILITY
       The SQL standard includes an EXECUTE statement, but it is only for use
       in embedded SQL. This version of the EXECUTE  statement	also  uses  a
       somewhat different syntax.
