EXECUTE
Executes a prepared SQL statement.
Synopsis
EXECUTE <name> [ (<parameter> [, ...] ) ]
Description
EXECUTE
is used to execute 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 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 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 PREPARE
.
Parameters
Examples
Create a prepared statement for an INSERT
statement, and then execute it:
PREPARE fooplan (int, text, bool, numeric) AS INSERT INTO
foo VALUES($1, $2, $3, $4);
EXECUTE fooplan(1, 'Hunter Valley', 't', 200.00);
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.
