I have the following Query and i need the query to fetch data from SomeTable based on the filter criteria present in the Someothertable. If there is nothing present in SomeOtherTable Query should return me all the data present in SomeTable

SQL SERVER 2005

SomeOtherTable does not have any indexes or any constraint all fields are char(50)

The Following Query work fine for my requirements but it causes performance problems when i have lots of parameters.

Due to some requirement of Client, We have to keep all the Where clause data in SomeOtherTable. depending on subid data will be joined with one of the columns in SomeTable.

For example the Query can can be 

SELECT     * FROM     SomeTable WHERE     1=1  AND ( SomeTable.ID in (SELECT DISTINCT ID FROM SomeOtherTable  WHERE Name = 'ABC' and subid = 'EF') OR 0=(SELECT Count(1) FROM SomeOtherTable WHERE spName = 'ABC' and subid = 'EF') )  AND      (     SomeTable.date =(SELECT date FROM SomeOtherTable  WHERE Name = 'ABC' and subid = 'Date')     OR     0=(SELECT Count(1) FROM SomeOtherTable WHERE spName = 'ABC' and subid = 'Date')     )

EDIT———————————————-

I think i might have to explain my problem in detail:

We have developed an ASP.net application that is used to invoke parametrize crystal reports, parameters to the crystal reports are not passed using the default crystal reports method.

In ASP.net application we have created wizards which are used to pass the parameters to the Reports, These parameters are not directly consumed by the crystal report but are consumed by the Query embedded inside the crystal report or the Stored procedure used in the Crystal report.

This is achieved using a table (SomeOtherTable) which holds parameter data as long as report is running after which the data is deleted, as such we can assume that SomeOtherTable has max 2 to 3 rows at any given point of time.

So if we look at the above query initial part of the Query can be assumed as the Report Query and the where clause is used to get the user input from the SomeOtherTable table.

So i don’t think it will be useful to create indexes etc (May be i am wrong).
