EXECUTE stmt_name [USING expression[, expression] ...]
MariaDB starting with 10.2.3
EXECUTE with expression as parameters was introduced in MariaDB 10.2.3. Before that one could only use variables (@var_name) as parameters.
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
USING 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 the statement.
You can execute a given prepared statement multiple times, passing different variables to it or setting the variables to different values before each execution.
If the specified statement has not been PREPAREd, an error similar to the following is produced:
ERROR 1243 (HY000): Unknown prepared statement handler (stmt_name) given to EXECUTE
See example in PREPARE.
