Question

我有一个包含这些列的表：

用户名 TotalTransactions SKU

我想创建一个名为Over：

的自动生成列

如果SKU是abc和TotalTransactions＆gt; 6,000，然后Over是真的：

UserName        TotalTransactions  Sku  Over
joe@mysite.com  6001               abc  True

如何使用If语句添加计算列？这是我的代码：

select settings.UserName, SUM(TransactionCount) as TransactionCount, settings.SettingValue as Sku,
CASE WHEN settings.SettingValue = 'abc' AND TransactionCount > 6000 
 THEN 'True' ELSE 'False' END As Over
from jma_qb_trans_count trans
Inner Join jma_settings settings on settings.UserName = trans.UserName
where settings.SettingName = 'QB:JMAWebStoreSku' and settings.SettingValue != ''
Group by settings.UserName, settings.SettingValue, Over
Order By settings.UserName

当我使用此代码时，收到此错误：

Msg 156, Level 15, State 1, Line 3 Incorrect syntax near the keyword 'Over'.

Answer 1

我相信你正在寻找（添加到Select语句）：

CASE WHEN SKU = 'abc' AND TotalTransactions > 6000 
     THEN 'True' ELSE 'False' END AS Over

使用If语句计算列
