Question

I am trying to build the following sp :

USE [MarMoniApp]
GO
/****** Object:  StoredProcedure [dbo].[Desc_by_date]    Script Date: 10/23/2012     09:01:40 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[Desc_by_date]
@DateToSearch varchar(50)
AS
BEGIN
select a.ticker,a.First_T, a.Last_T, a.Size_mln, a.pct_d_vol,a.a_trad,a.coolname,a.recency,b.Analyst
from Order_Desc a

CASE
When a.coolname = 'ELTORO'
then (Inner join MarMoniApp.dbo.Namelist b on a.ticker = b.ticker )
END

where convert(datetime, cast(rtrim(First_T) AS nvarchar)) > DateToSearch 
order by  CONVERT(DATETIME, cast(rtrim(First_T) AS nvarchar) )  DESC
END

I want to do the inner join only if the “coolname” is equal to eltoro, but it seems that my syntax is not correct.

Answer 1

What about making two select statement and then union them.

select ... from Order_Desc a
Inner join MarMoniApp.dbo.Namelist b on a.ticker = b.ticker
where a.coolname = 'ELTORO' AND ...

union

select ... from Order_Desc a
where a.coolname != 'ELTORO' AND ...
