EXECUTE
EXECUTE — execute a prepared 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
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.
Examples
Examples are given in Examples in the PREPARE documentation.
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.
