Its big deal you should use join. otherwise view.

Try something like this: declare @sql as varchar ( max ) set @sql = 'select * from table where ordernumber = 12345' ; while(condition) begin set @sql += 'required tables' ; end exec (@sql)

Hi Nigel, Thanks for the reply. Can you please provide me the sample code so that i can understand and try the same.

Nigel Fernandes · Answer

Create the query using a for loop in a string and then use exec (string) dynamically.

Hi Rajesh and Daniel Thanks for your replies. Is there anyway other than joins to achieve my query. I need to get the data from all the 200 tables and loop through the tables and display them in single table. Thanks
