You need to use JOIN, see examples here: SQL Joins[^]

Another option is UNION, this can also be used for non-related tables: SQL UNION Operator[^]

To select only one row use TOP: SQL SELECT TOP, LIMIT, ROWNUM[^]

yes but with join I select all rows that have a correspondence, I want only a specific raw

You can also use DISTINCT in combination with a WHERE clause, see the examples on the W3Schools website. It pays to study SQL as it is used almost everywhere.
This will take all rows from 1st table and only 1st row from second table
select * from myTable
union all (select top 1 * from myTableDuplicate)

Id	fName	
1	Srikanth
2	sunil	
3	Shilpa	
1	Srikanth

This will take all the columns from the first table and only Id column from the second table
select * from myTable M
join (select ID from myTableDuplicate) as D on M.Id=D.ID

Id	fName		ID
1	Srikanth	1
2	sunil		2
3	Shilpa	    3
