Hi Guys

I am trying to build a simple Select statement.

DECLARE @BasicField AS VARCHAR(50)
set @BasicField = 'City'
Select * from dbo.AMGR_Client_Tbl
where  @BasicField = 'Slough'

This does not bring any data back.

i thought the select statement would be:
Select * from dbo.AMGR_Client_Tbl
where City = 'Slough'
This brings a number of rows back.

Any help please!!

DECLARE @BasicField AS VARCHAR(50)
set @BasicField = 'City'
Select * from dbo.AMGR_Client_Tbl
where  @BasicField = 'Slough'
This query would be trying to find rows where 'City'='Slough' which will never return any rows.

DECLARE @BasicField AS VARCHAR(50), @sql nvarchar(2000)
set @BasicField = 'City'
set @sql = 'Select * from dbo.AMGR_Client_Tbl '
set @sql = @sql + ' where ' + @basicfield + ' = ''''slough'''
