Solution 1

TSQL
SELECT TOP 1 * FROM Registration_Master

ORACLE (source[^])
If you want just a first selected row you can:
select fname from MyTbl where rownum = 1

you can also use analytic functions to order and take the top x
select max(fname) over (rank() order by some_factor) from MyTbl

MySQL
SELECT * FROM Registration_Master LIMIT 1;


If you want the latest record however, in each case you will have to order your records based on your primary key descending(or other column that can be sorted to provide the latest record)
