in your syntax you have to change the command " EXCU " to " EXEC ".
EXEC UPDATE_PERSON ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ? OUTPUT i have to mention that there is no need for { }
other than that you have to be aware of your full path of the SP that your are executing " by means of specifying [databaseName].[dbo]. if needed
