How to access data from two different databases (Views: 34)
Problem/Question/Abstract: Is it possible for access data from two different database such as... SELECT A.EMP_NAME, B.DEPT_DESC FROM DB1.TB1 A, DB2.TB1 B WHERE A.EMP_DEPT = B.DEP_KEY If so how? Answer: Yes, this is called a heterogeneous join. An example of this is like: SELECT DISTINCT c.cust_no, c.state, o.order_no, i.price FROM ':Local_alias:customer.db' c, ':IB_alias:order' o, ':SYB_alias:lineitem' i WHERE o.cust_no = c.cust_no and o.order_no = i.order_no The first part between the :: is the BDE alias for the database you want to include in the heterogeneous join. |
