It is very easy to create a table in DB2. But how can I create a table with an auto-incrementing column? The following describes how to create an auto-incrementing table in DB2 for your reference.

 
 

  
  
Create table test (id integer not null generated always as identity (startwith 1, increment by 1, no cache ),
  
  
Name varchar (20 ))
  
  
 
  
  
Db2 => select * from test
  
  
 
  
  
ID NAME
  
  
-------------------------------
  
  
 
  
  
0 records are selected.
  
  
 
  
  
Db2 => insert into test (name) values ('wjz ')
