我的意思是...... 我们假设您在
下有以下单元格值column1
1. Sedan
2. Trucks
3. SUV
4. SportsCar
我想要做的是创建一个向Sedan,Trucks,SUV等插入值1的查询。(仅举几个单元格值作为示例,我需要为数百行执行此操作。)
看起来像这样:
1. Sedan1
2. Trucks2
3. SUV3
4. SportsCar4
这甚至可能吗?

SQL服务器
with Products as
(
select product, row_number() over(order by a_column) as R_ord
from mytable
)
update Products
set product = product + cast(R_ord as varchar(50))
另外,为什么?为什么不用表来做呢?

CREATE TABLE #b
([column1] varchar(9))
;
INSERT INTO #b
([column1])
VALUES
('Sedan'),
('Trucks'),
('SUV'),
('SportsCar')
;
with Products as
(
select [column1], row_number() over(order by [column1]) as upd
from #b
)
select [column1] = [column1] + cast(upd as varchar(50)) from products
输出
column1
Sedan1
SportsCar2
SUV3
Trucks4

一种方法是将值与row_number函数上的强制转换连接起来。但如前所述,不确定为什么要这样做。
select top 10
column1 + cast(row_number() over (order by column1 ) as varchar(10))
from my table
