Question

假设查询“从地址中选择streetAdr”返回“236 a1 road”“333 a2 road”和444 a4 road“as 3 rows。我怎么只能在SQL Server中显示”236“”333“和”444“

Answer 1

尝试：

Select left(yourcolumn, charindex(' ',yourcolumn)) ...

Answer 2

为了安全起见，如果您的任何地址只有一个号码而没有别的：

declare @Address table (AddressLine1 nvarchar(50) NOT NULL)
insert into @Address values ('236 a1 road')
insert into @Address values ('333 a2 road')
insert into @Address values ('444 a4 road')
insert into @Address values ('555')
select
   CASE
      WHEN charindex(' ', AddressLine1) > 0 THEN
         Left(AddressLine1, charindex(' ', AddressLine1))
      ELSE
         AddressLine1
   END AS AddressLine1
from @Address
