Here is the text in the Oracle manual: FOR UPDATE [OF [[schema .] { table | view } .] column

[, [[schema .] { table | view } .] column]...

]

[ NOWAIT | WAIT integer ]
I found this by going to technet.oracle.com and searching. I hadn't realized that you could just lock a column.
I don't know if it really works or not, but this is what the documentation specifies.

hi all,

I remember that oracle has ability to lock not just the entire row, but a specific column in this row.
How to do this ?

When I use:
"SELECT <column>
FROM <table>
FOR UPDATE OF <column>"
the entire row is locked so, how to lock a column not the enire row ?
