EXECUTE(l) SQL - Language Statements (2002-11-22) EXECUTE(l)
NAME
EXECUTE - execute a prepared query
SYNOPSIS
EXECUTE plan_name [ (parameter [, ...] ) ]
INPUTS
plan_name
The name of the prepared query to execute.
parameter
The actual value of a parameter to the prepared query.
This must be an expression yielding a value of a type
compatible with the data-type specified for this
parameter position in the PREPARE statement that
created the prepared query.
DESCRIPTION
EXECUTE is used to execute a previously prepared query.
Since prepared queries only exist for the duration of a
session, the prepared query must have been created by a
PREPARE statement executed earlier in the current session.
If the PREPARE statement that created the query specified
some parameters, a compatible set of parameters must be
passed to the EXECUTE statement, or else an error is raised.
Note that (unlike functions) prepared queries are not
overloaded based on the type or number of their parameters:
the name of a prepared query must be unique within a
database session.
For more information on the creation and usage of prepared
queries, see PREPARE [prepare(l)].
COMPATIBILITY
SQL92
SQL92 includes an EXECUTE statement, but it is only for use
in embedded SQL clients. The EXECUTE statement implemented
by PostgreSQL also uses a somewhat different syntax.
