Hi,
I would like to know the different flavours of the SQL-92-ANSI standard for SQL. Oracle provides SQL-PLUS as its SQL product.
I would like to find out the different versions of SQL-92 from different RDBMS vendors. This is for comparison purposes. Could anyone help me please.
Thanks
Raja

SQL*Plus is Oracle's Command Line Tool for issuing SQL commands. With the environmental setting FLAGGER (Usage: SET FLAGGER { OFF | ENTRY | INTERMEDIATE | FULL }) you can decide whether you want to follow the SQL-92 standard. Example (DECODE is an Oracle specific built-in):
==========================
SQL> show flagger
flagger OFF
SQL> select decode(dummy,'X','Y',dummy)
2 from dual;
D
-
Y
SQL> set flagger full
SQL> select decode(dummy,'X','Y',dummy)
2 from dual;
from dual
*
ERROR at line 2:
ORA-00097: use of Oracle SQL feature not in SQL92 Full Level
ORA-06550: line 2, column 8:
PLS-01416: Use of <id> (<value>...) here
====================
All depends, of course, what version of Oracle we're talking about. Oracle 9i is contains even more features concerning ANSI:
