SQLCODE comed across on DUN system
9 25, 2008 IBM MainFrame
With finishing of the DUN system, I writed down the SQLCODE comed across on DB2.
1.SQLCODE = -540, ERROR: THE DEFINITION OF TABLE IBMUSER.DUNBSINF IS
INCOMPLETE BECAUSE IT LACKS A PRIMARY INDEX OR A REQUIRED UNIQUE INDEX
意思是说建表后一定要建立相应的primary key的index 或者是unique index,某一个columm
指定为primary key后,就自动加上了unique 限制.
