Question

我在一家医院集团工作，我们有多个站点服务器，组织到大约6个地区。我正在SCCM中编写一个sql查询，并希望用站点解析区域，这证明是一个挑战...我想根据我查询的区域做一个有选择性的where语句，但我不确定如果可以的话。我知道以下代码已被破坏...特别是where行附近的case语句。在这种情况下是否有类似的东西可供使用？

Answer 1

您不能发出where声明：

  (case when @test = 'SCAH' and v_FullCollectionMembership.SiteCode='VN1' then 'true'
        when @test = 'CCS' and e v_FullCollectionMembership.SiteCode in ('SS1', 'SC1') 
        . . .
  end) = 'true'

我建议将其移至where子句，而不是试图将其保留在on子句中。如果它保留在on子句中，则需要在其前面加and（或or，具体取决于逻辑）。

Answer 2

如果要执行“selective where”子句，还可以使用动态sql。


declare @sql varchar(max)
set @sql = 'select * from table '
if( @regions = '??')
  set @sql = @sql + ' where ....'
else if( @regions = '???' )
  set @sql = @sql + ' where ...'
exec(@sql)

SQL Conditional Where语句？
