1574.0. "PLS-00201 when using system tables" by PRSSOS::MISTLER () Fri Jun 06 1997 08:55

	Hello,

	Sorry for my ignorance but I'm new to Oracle. I can create a small
procedure using my tables without any problem but when I want to use the
system tables, SQLPLUS is complaining about to declare the system tables as 
identifier
	I've try many different codes but unsuccessfully. 

	Where did I miss something ?

	Regards,

	didier

	Oracle V7.3.2 and DU V4.0
