【问题描述】：

我有三张桌子

表 1 供应商 (sno, sname, city)

1, ahmad, jeddah

表 2 部分 (pno, pname, color)

1, laptop, red

表 3 supplier_parts_shipment (shno, sno, pno, date)

1, 1, 1, 2014

我需要删除 city='jeddah'and color='red' 的货件 - 怎么做？

  1  delete from supplier_parts_shipment
  2  where sno in (select sno from supplier where city='jeddah')
  3  and pno(select pno from parts where color='red')
  4* and (sno=sno) and (pno=pno)
SQL> /
and pno(select pno from parts where color='red')
        *
ERROR at line 3:
ORA-00936: missing expression

【问题讨论】：

再读一遍你的第三行
这是 Oracle，从 ORA-.... 错误消息来看，NOT 用于（Microsoft）SQL Server - 相应地更新了标签跨度>

标签： oracle join

【解决方案1】：

试试这个：

delete from supplier_parts_shipment
where sno in (select sno from supplier where city='jeddah')
and pno in (select pno from parts where color='red');

【解决方案2】：

3  and pno in (select pno from parts where color='red')

【讨论】：

【解决方案3】：

 delete from supplier_parts_shipment as A
 where A.sno in 
 (select B.sno from supplier as B, supplier_parts_shipment  as C, parts as D
  where B.city='jeddah' and D.color='red' and C.sno=B.sno and C.pno=D.pno)

【解决方案4】：

 delete sps from supplier_parts_shipment as sps
 join supplier as sup on sps.sno = sup.sno
 join  parts as prt on sps.pno = prt.pno
 where sup.city = 'jeddah' AND prt.color = 'red'

并且在您的查询中缺少第 3 行

和 pno in（从 color='red' 的部分中选择 pno）
