T-SQL creating a dynamic where statement?

Question

I know this is not possible, but is there something that would work? Basically I want the where statement to be dynamic, allowing me to pass it any string, which it will be able to search upon.

Declare @search varchar(80)
set @search = 'RegionID'

Select * from TBL_TripDetails
Where @search = '1'

Thanks for your answers. After reading a few documents, I have decided to use multiple select statements instead of using dynamic sql. thanks!

Answer 1

declare @sql nvarchar(max);
set @sql = N'select * from table where ' + quotename(@search) + N'=''1''';
exec sp_executesql @sql;
