My usage like this (sql):
“select material from dish where dishName = ?”
“select xxx from yyy where aaa = ? and bbb = ? and ccc = ?”
Such like this. The num of “?” is arbitrary. And the content of “?” is stored in variables.
My ActionTask sqlQuery have a stringField(for sql) and list<string>Filed(for “?”s). So strings in list should be pointed by variables which are in blackBoard.
I’m really appreciate if can do me a favor and tell me a correctly using.
