Coding Example: 1) Defining the Stored Routine in MySQL: CREATE PROCEDURE multiply(IN pFac1 INT, IN pFac2 INT, OUT pProd INT) BEGIN SET pProd := pFac1 * pFac2; END 2) Executing in Python: args = (5, 5, 0) # 0 is to hold pprod await cursor.callproc('multiply', args) print(await cursor.fetchone()) For OUT and INOUT parameters the user should provide the type of the parameter as well. The argument should be a tuple with first item as the value of the parameter to pass and second argument the type of the argument. In the above example, one can call callproc method like: args = (5, 5, (0, 'INT')) await cursor.callproc('multiply', args) The type of the argument given in the tuple will be used by the MySQL CAST function to convert the values in the corresponding MySQL type (See CAST in MySQL Reference for more information) Does not return a value, but a result set will be available when the CALL-statement execute successfully.
