The MySQL stored procedure appears out of or INOUT argument for routine

Out or INOUT argument-routine * is not a variable or NEW pseudo-variable

I look at the Internet a lot of the time when the call did not add variables, but my side is called in the program stored procedures, so the problem is not here, but the main reason is the reason for the variable

PARAM[9].  Value= ParameterDirection.Output; The previous Error statement

PARAM[9].  Direction = ParameterDirection.Output; After changing the statement, really is accidentally debugging large half-day, and will not error
