[USING @var_name [, @var_name] ...]
After preparing a statement with
PREPARE, you execute it with an
EXECUTE statement that refers to
the prepared statement name. If the prepared statement contains
any parameter markers, you must supply a
clause that lists user variables containing the values to be bound
to the parameters. Parameter values can be supplied only by user
variables, and the
USING clause must name
exactly as many variables as the number of parameter markers in
You can execute a given prepared statement multiple times, passing different variables to it or setting the variables to different values before each execution.
