hi, thanks,,,,,,,,,
create table emp ( id,name,date,empno);
create table emp_status(slno,ename,empno);
i need to update "emp.name" in "emp" table from "emp_status.ename"
where emp.empno=emp_status.empno;
i.e) for all matched "empno" from both table, update "emp.name" from "emp_status.ename"Whats the relationship between emp and emp_status tables? If there exists one to one mapping for empno in both tables, then try
update emp e
set    e.name = (select es.ename
                 from   emp_status es
                 where  e.empno = es.empno)
