mysql这种select怎么写？
SELECT spId FROM tbl_goods WHERE goodsId=2; /*2为传入的参数*/


SELECT spMemberName FROM tbl_shopInfo WHERE spId=2; /*2为第一条语句的结果*/

SELECT qqNumber FROM tbl_scmember WHERE memberName='hehe';/*hehe为第二语句的结果*/

如果用一条语句得到结果。

[解决办法]

SQL code

select qqNumber from tbl_goods g,tbl_shopInfo s,tbl_scmember t where g.spId=s.spId  and s.spMemberName=t.memberName and g.goodsId=2
