I have two tables EMP1&EMP2 both having same fields if any updations made in emp1 how to reflect on emp2

try to write update/delete/insert trigger on emp2 which will fire on updation/deletion/insertion in emp1

Using Joins we can update the fileds.

use alias names for common fields which r present in Emp1 and Emp2

 If Emp1 and Emp2 have  common  fields namely field1,field2 then: 

 update E1.field1,E2.field1 from Emp1 E1,Emp2 E2 where E1.field1=E2.field2

write triggers on emp2,so that any updations in emp2 will reflect emp1.
for this we use trigger structure,implement the logic and execute.

i think if any updation made in emp1 it wil not reflect in emp2.bcz table name r difference.

Use triggers to guarantee that when a specific operation is performed, related actions are performed.

write trigger

Use DML Triggers to apply the same action to another table as well.
