RE: what is the difference between "for update' and "selectforupdate" ?

Thanks Hossein

You mentioned the difference between update() and do update () but I wants to know  the exact difference between

while select forupdate <Table name>

where condition...

{

     <Table.update() OR Table.doUpdate();>

}

And

table.selectforupdate(true);

Is't both are same statement?

Please give me more shed on this.

Thanks!
