EXECUTE
EXECUTE
EXECUTE - execute a prepared statement
Synopsis
EXECUTEname[ (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
-
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 that is compatible with the data type of this parameter, as was determined when the prepared statement was created.
Outputs
The command tag returned by
EXECUTE
is that of the prepared statement, and not
EXECUTE
.
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.
