Sql server 使用sql查询连接两个表

我有两个记录表，一个是

temp

，第二个是

temps

， 我想按第二个表中提供的部门更新状态

我需要第一个表计数将更新在第二个表NotYetTaken，WorkInProgress，根据状态完成

比如说,， 将更新护理部门，在Temps表格中有多少已完成、待处理的工作在进行中替换为NULL

临时记录 临时唱片 给出sql查询解决方案

您的表结构未规范化

我希望您创建一个具有状态注册表的表，如下所示：

CREATE TABLE STATUS
(id varchar(36), description varchar(50))

然后，您在

temp

表中引用了

status

表上的外键约束

但与此同时，您可以尝试以下方法：

UPDATE temps
SET NOTYETTAKEN =
    (SELECT [t.COUNT] FROM temp t WHERE T.department = temps.department
    AND t.status = 'NOT YET TAKEN'),
WORKINPROGRESS =
    (SELECT [t.COUNT] FROM temp t WHERE T.department = temps.department
    AND t.status = 'WORK IN PROGRESS'),
COMPLETED =
    (SELECT [t.COUNT] FROM temp t WHERE T.department = temps.department
    AND t.status = 'COMPLETED'),
UNDERTESTING =
    (SELECT [t.COUNT] FROM temp t WHERE T.department = temps.department
    AND t.status = 'UNDER TESTING'),
NOTPOSSIBLE =
    (SELECT [t.COUNT] FROM temp t WHERE T.department = temps.department
    AND t.status = 'NOT POSSIBLE')

给出您需要的输出格式亲爱的，您的表结构与您的temp和temp样本不同tables@rajeshpanchal：现在我正确地更新了它，但我没有得到结果，我需要这样的输出。@Joe Taras:我只使用临时表。。
