Equivalent of First() in MS-SQL

I want to convert a query in Access to MS-SQL Query. The Query in Access has First() function. Is there any equivalent function in MS-SQL ?
What exactly will First() do ? Is that it will pick the first record in the query (assume the query contains group by clauses) or the first inserted record in the table ?

If i want to find the first inserted record then i want to know the equivalent of rowid as in Oracle

If you simply want to limit the number of rows returned from a TSQL script to 1 you can:

  SET ROWCOUNT 1   -- forces results to be limited to one record
  SELECT ......    
  SET ROWCOUNT 0   -- results will return all records

If you want to know the IDENTITY value of a record you just added to a table (assuming the table has an IDENTITY column) you can use:

  SELECT @@Identity

immediately after your INSERT statement.  Note that @@Identity is connection specific.
