Hi Jack,

After having created a suitable table, a cut and paste of that SQL returns "no rows selected" running 8.1.6 on NT. No error message. I've used it under 8.1.6 on Solaris before, and it has worked there too.

Steve,

Here's what I did to test Select...For Update Skip Locked.

The same ORA-03113 happens running SQL*Plus 8.1.6 or 8.1.7 (both window and command line versions) against either Oracle8i EE 8.1.6.0.0 or 8.1.7.0.0. SQL*Plus and the databases are running under Windows2000. Both the simple Select and the PL/SQL block work (or wait) as expected if the "Skip Locked" phrase is left off and either NoWait or Wait is specified.

First, in SQL*Plus session 1:

SQL> Select Document_ID
  2 from Documents
  3 Where RowNum < 3
  4 For Update;

DOCUMENT_ID


    9789959
    9789960

Then, in SQL*Plus session 2:

SQL> Select Document_ID
  2 from Documents
  3 Where RowNum < 3
  4 For Update Skip Locked ;
Select Document_ID
*
ERROR at line 1:
ORA-03113: end-of-file on communication channel

Even putting the Select in a PL/SQL anonymous block doesn't help.
In SQL*Plus session 2:

Declare

  Type rc Is Ref Cursor ;
  c    rc               ;
  n    Number           ;

Begin
  Open c For
  'Select Document_ID From Documents Where RowNum < 3 For Update Skip Locked' ;
  Loop
    Fetch c Into n ;
    Exit When c%NotFound ;
    DBMS_Output.Put_Line('Document_ID= ' || To_Char(n)) ;   End Loop ;
  Close c ;
End;
/

Does it work on other OSs or Oracle versions? Am I missing something?

Thanks.

Jack
