Merge into Table1 t1 Using (select Column1, column2 from table2) T2 On t1.column1 = T2.column1 When matched then update set t1.column2 = T2.column2 When not matched then insert values (COLUMN1,COLUMN2) The above is to insert or update the data in the table2 into the Table1. But for developers, we're working with a single record to determine whether this data is an insert or an update. The treatment for DB2 is as follows: Merge into Table1 t1us

The tablespace is the logical layer between the database and the tables stored in the database. Create a tablespace in the database and a table in the tablespace. One obvious advantage of using tablespaces is that data can be reasonably distributed and stored on different disks or in different locations on disks, which helps improve data access efficiency. DB2 tablespaces are managed in two ways: System Man
