EXECUTE
SQL - Language Statements
EXECUTE
execute a prepared statement
EXECUTE plan_name [ (parameter [, ...] ) ] [ INTO [ TEMPORARY | TEMP ] table ]
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.
Like SELECT INTO, EXECUTE can
store the results of executing a query into a newly-created
table, by specifying an INTO> clause. For more information on this behavior,
see .

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