I have an "SQL script presenter" that presents in a TIB_GRID the data
arriving from an SQL script fed to a TIB_QUERY. I want to allow the
grid columns to be ordered by clicking on the column titles.

Using a script like "select field01 from table" there is no problem. I
use grid.gridFields to get fields names like "field01" and feed these
into the ordering properties of the query.

Using a script like "select field01 as alias01 from table",
I need "field01" for the query ordering properties. So far I can
find "alias01" and have not found "field01". Any suggestions as to how
to find "field01" from the existing grid or query properties or
methods?
Thanks
