There are two tables tblUser and tblHelpAndSupport and the database is SQL server 2005. They have no common field. UserId is the primary key of tblUser. But tblHelpAndSupport doesn't contain UserId. I have to retrieve all data from tblHelpAndSupport where the condition is UserId='001' in tblUser table. How can I retrieve data on the above condition?

There's a million ways, but we can't give you any of them if you don't give us more information. What are you trying to select from help and support, what are you going to use as a join parameter, what is the schema of your tables? On top of that, what kind of database?

Can you please explain some of the ways? I will be gratful to you

It's as easy as

SQL

Select columnsYouWantFromBothTables
From tblUser , tblHelpAndSupport
Where tblUser.UserId = '001'

You don't have to specify a join - it will retrieve the single row from User and all orws from HelpAndSupport

Thank you Mr. _Maxxx_. If I want to retrieve only one row then is it possible?

_Maxxx_ 6-Jun-13 2:12am

But which row?
