Runs a prepared SQL statement.
EXECUTE <name> [ (<parameter> [, ...] ) ]
EXECUTE is used to run a previously prepared statement. Since prepared statements only exist for the duration of a session, the prepared statement must have been created by a
PREPARE statement run earlier in the current session.
PREPARE statement that created the statement 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 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
Create a prepared statement for an
INSERT statement, and then run it:
PREPARE fooplan (int, text, bool, numeric) AS INSERT INTO foo VALUES($1, $2, $3, $4); EXECUTE fooplan(1, 'Hunter Valley', 't', 200.00);
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.
