Oracle 8.0 and before requires that a function have the following in the header in order for it to work in a select statement:

    PRAGMA RESTRICT_REFERENCES(...)
Oracle, in its infinite wisdom, didn't put the pragma in most of its internal functions...  

Oracle 8i got rid of this PRAGMA. You still can't directly update the database in a select statement.

I get a version-specific glitch ( works in 816, fails in 805 ) for a call to the DBMS_UTILITY.GET_TIME built-in:

###################### 

SQL> select dbms_utility.get_time from dual; select dbms_utility.get_time from dual

       *
ERROR at line 1:
ORA-06571: Function GET_TIME does not guarantee not to update database

###################### 

Any ideas why 80520 doesn't like this?

TIA,

• Ross

p.s. a simple assignment, like, for example time := DBMS_UTILITY.GET_TIME;

        fails as well.

p.p.s I know how to use V$TIMER, so i am looking for a "why this doesn't work"

          not a "How to fix it by using V$TIMER" answer.
