select * from Appointment where yyid in ('2021051100000012','2021051900000018','2021052100000021') 用以下代替: select * FROM Appointment a JOIN ( select '2021051100000012' yyid union select '2021051900000018' UNION SELECT '2021052100000021' ) b on a.yyid=b.yyid
select a.* from Appointment a where a.yyid in(select yyid from OrderPayment where ReceivableAmount=3000 ) 用下面的语句替换: select a.* from Appointment a where 1=1 and exists(select 1 from OrderPayment where yyid=a.yyid and ReceivableAmount=3000 )
