SQL 服务器：打印生成 SQL 查询

Question

有谁知道在 SQL 服务器中执行 SQL 查询后如何打印 output 查询？

select count(eo.equal_opps_id) as 'Age 40 - 49'
from dbo.app_equal_opps eo, dbo.app_status s
where eo.date_of_birth > DateAdd(yy,-49,getDate())
and eo.date_of_birth < DateAdd(yy,-39,getDate())
and eo.application_id = s.status_id
and s.job_reference_number = '33211016'
and s.submitted = 1    

上面显示了一个 SQL 查询，但是，一旦它被执行，我想看看在以下部分创建的实际日期值

DateAdd(yy,-49,getDate())
DateAdd(yy,-39,getDate())

换句话说，一旦执行查询，我可以打印 SQL 查询 output 以便它显示类似这样的内容

select count(eo.equal_opps_id) as 'Age 40 - 49'
from dbo.app_equal_opps eo, dbo.app_status s
where eo.date_of_birth > '1962-05-04 13:00:00.000'
and eo.date_of_birth < '1972-05-04 13:00:00.000'
and eo.application_id = s.status_id
and s.job_reference_number = '33211016'
and s.submitted = 1

与往常一样，我们将不胜感激任何反馈。

感谢大家。

Answer 1

将这两个日期添加到您的 select 列表中：

select 
   count(eo.equal_opps_id) as 'Age 40 - 49' 
  ,DateAdd(yy,-49,getDate()) as LesserDate
  ,DateAdd(yy,-39,getDate()) as GreaterDate
from 
  dbo.app_equal_opps eo, dbo.app_status s 
where 
  eo.date_of_birth > DateAdd(yy,-49,getDate()) 
  and eo.date_of_birth < DateAdd(yy,-39,getDate()) 
  and eo.application_id = s.status_id 
  and s.job_reference_number = '33211016' 
  and s.submitted = 1

我能想到的唯一方法是混乱。 您可以将 sql 构建为字符串，然后使用内置 function 中的 exec 执行它。

declare @sql as varchar(max)

select @sql = '
select count(eo.equal_opps_id) as ''Age 40 - 49''
from dbo.app_equal_opps eo, dbo.app_status s
where eo.date_of_birth > ' + ( select cast(DateAdd(yy,-49,getDate()) as varchar(100)) ) + '
and eo.date_of_birth < ' + ( select cast(DateAdd(yy,-39,getDate()) as varchar(100)) ) + '
and eo.application_id = s.status_id
and s.job_reference_number = ''33211016''
and s.submitted = 1'

print @sql
exec(@sql)
