ASP.NET查(高手)
要做表的查：
表一：SFCYML
字段：ML001（）、ML002（）、ML005（工）、ML006（工）、ML015（品）、ML011（投入批）、ML012（出批）、ML016（）、ML017（各段）、ML052（幅）、ML007（）、ML001（）；
表二：MOCTA
字段：TA001、TA002、UDF01（客）
表系：ML005和TA001；ML006和TA002
要用通入品号(品)或出批(ML012)或工(ML006)
查.
要示的信息:、、工、工、品、投入批、出批、、各段、幅、、、客.
全部示我已，怎查？？？

查询？太广了的，首先你得明确需要根据哪几个字段查询，然后在你已有的sql语句上面添加where条件就可以了
select SFCYML.ML001,SFCYML.ML002,SFCYML.ML005,SFCYML.ML006,SFCYML.ML015,SFCYML.ML011,SFCYML.ML012,SFCYML.ML016,SFCYML.ML017,SFCYML.ML052,SFCYML.ML007,MOCTA.TA001,MOCTA.TA002,MOCTA.UDF01 from SFCYML Inner Join MOCTA on SFCYML.ML005=MOCTA.TA001 and SFCYML.ML006=MOCTA.TA002 where 。。。。
