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.
For more information on the creation and usage of prepared queries,
see PREPARE.
