MyTable has 3 fields: cName, cName2 and cNameSearch.
cName2 is used for cName change and cNameSearch to optimize search.
When cName2 is not empty its lower case value must be copied
in cNameSearch otherwise the cName will be. I would like to use trigger
update (in the table) for that. But I do not know what enter in the
"update trigger" field in the table properties. Someone could show me
the way to do a trigger in VFP? Thank you very much.
