eid    empname    eaddress
----   --------   ---------
1      venu       hyd
2      ravi       mad
3      kiran      ban
4      raju       hyd

If firstrow in empname column is venu then it has to change all the empname columns values to 'venu' like below table


eid    empname    eaddress
----   --------   ---------
1      venu       hyd
2      venu       mad
3      venu       ban
4      venu       hyd

If firstrow in empname column is NULL then it has to take the 2nd row value and change all empname columns values to 2nd row value i.e 'ravi' like below table




eid    empname    eaddress
----   --------   ---------
1      null       hyd
2      ravi       mad
3      kiran      ban
4      raju       hyd


EXAMPLE



eid    empname    eaddress
----   --------   ---------
1      ravi       hyd
2      ravi       mad
3      ravi       ban
4      ravi       hyd

Post the code that you tried that didn't work and we will try to help you fix it

1 solution

That sounds like an odd thing to do, but...
SQL
UPDATE MyTable SET empname = 
   (SELECT TOP 1 empname 
    FROM MyTable
    WHERE empname IS NOT NULL
    ORDER BY eid ASC)
