我如何做这个简单的条件更新？

Question

我有一个带有数据库（ITinventory）的SQL 2000服务器和一个也称为ITinventory的表。我想创建一个查询字段'Sta​​tus'的查询，如果状态为'dispos'，那么我想将'location'字段设置为'dispos'。

Answer 1

试试这个：

UPDATE ITInventory SET Location = 'disposed' 
WHERE Status = 'disposed' AND Location != 'disposed'

Answer 2

update 
    ITinventory 
set 
    Location = Status 
where 
    Status = 'Disposed'

Answer 3

UPDATE ITInventory SET Location = 'disposed' WHERE Status = 'disposed'

这个SQL正在做出各种假设，否则在OP中没有明确......

Answer 4

update ITinventory
set location='disposed'
where status ='disposed'

Answer 5

UPDATE ITinventory
SET location = 'disposed'
WHERE status = 'disposed'
