Before Oracle9i appears, you can only make table redefinition by exporting and importing, so the process of table redefinition is an offline process. Even an online change ("ALTER TABLE ADD new_col number (3)") also results in an exclusive deadlock (exclusive locks), which requires that all DML (INSERT, UPDATE) operations be prevented before the DDL completes.
To solve this problem, Oracle9i introduced the online table redefinition function in its Dbms_redefinition software package. With the Dbm
subquery.Correlated subqueries can be introduced with in, not in, EXISTS, not EXISTS. For related subqueries, it should be noted that:(1) The related subquery for not in, not exists can use the left join instead of the notation. Like what:Select Pub_name from Publishers where pub_id Notin (SELECT pub_id from the TITLES WHERE TYPE = ' business ')Can be changed to write:SELECT A.pub_name from Publishers A leftjoin

Statement:
Select * From Table1 where TID in (2, 3) and select * From Table1 where tid = 2 or tid = 3
If they are the same, they will cause a full table scan. If there is an index on the TID, its index will also become invalid.
