Some tool kits for connecting to Oracle allow you to parse a statement but never execute it subsequently. This is done for a number of reasons:
- to check syntax etc;
- to be able to DESCRIBE the statement to dynamically build result arrays, variables etc;
- because the tool kit does it anyway because it was written that way.
I think I remember ADO being a "parse twice execute once" sort of thing - but that was years ago. (2003)
