-- 作者:125651911 -- 发布时间:2022/3/24 13:20:00 -- select语句 Select a.bh as 产品编号, a.mc as 名称, sum(b.sl) As 出库数量, sum(b.sl) As 入库数量 fro m cp a left join ck b on a.bh = b.bh left join rk c on a.bh = c.bh group by a.bh, a.mc 语法错误 (操作符丢失) 在查询表达式 \'a.bh = b.bh left join rk c on a.bh = c.bh\' 中。 select 不可以连接多个表吗? |
-- 作者:有点蓝 -- 发布时间:2022/3/24 13:42:00 -- 内部表,和access要这样 Select a.bh as 产品编号, a.mc as 名称, sum(b.sl) As 出库数量, sum(b.sl) As 入库数量 from (cp a left join ck b on a.bh = b.bh) left join rk c on a.bh = c.bh group by a.bh, a.mc 其实上面sql根本没有用到c表,可以去掉这个表的关联
