The returned throttling keyword string is generated based on SQL syntax. To throttle a specific value, you must add the value to the string. For example, if the original SQL statement is SELECT * FROM test where name = 'das', the following throttling keyword string is returned: SELECT~FROM~test~where~name. If you want to throttle the das value, you must add ~das to the string, so that the string becomes SELECT~FROM~test~where~name~das.
