Hi Yong,

That has to be FOR UPDATE SKIP LOCKED.
There is some stuff about it on the Ixora web site.

Hi, Riyaj,

Could you post your screen shot that shows select * from t1 skip locked? What version of Oracle are you using? Mine is 8.1.6 Enterprise Ed:

SQL> select * from test skip locked;
select * from test skip locked

ERROR at line 1:
ORA-00933: SQL command not properly ended

SQL> select * from test skip lock;
select * from test skip lock

ERROR at line 1:
ORA-00933: SQL command not properly ended

SQL> desc test

 Name                                      Null?    Type
 ----------------------------------------- -------- --------
 A                                                  NUMBER
 B                                                  ROWID
 D                                                  NUMBER

If you want to show only rows that are locked then you could use this undocumented feature: 'select * from t1 skip locked'. This will skip all the rows that have been locked.

Thanks
