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.
table
The name of the table in which to store the results of
executing the query (if it is a SELECT). If
no table is specified, the results are returned to the client
(as normal).

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.
Like SELECT INTO, EXECUTE can
store the results of executing the query into a newly-created
table, by specifying an INTO clause. For more information on this behavior,
see .

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.
