We already have such functionality:
dbExists( <cTable>, [<cIndex>], [<ulConnction>] ) -> <lExists>
It checks if table or index to given table exists.
F.e.:
dbExists( "test" )
returns true if table "test" exists. It's not necessary to add
file name extension. It will be done automatically by RDD.
And
dbExists( "test", "fisrt" )
checks if table "test" has index "first". Some RDDs like DBF*
may ignore table name during index checking.
We have also
dbDrop( <cTable>, [<cIndex>], [<ulConnction>] ) -> <lRemoved>
which can remove table with all related files (indexs and memos)
f.e.:
dbDrop( "test" )
or only given index, f.e.
dbDrop( "test", "fisrt" )
AFAIK SQLRDD does not support them at all. In ADS they are supported
but only using standard file API and it should be fixed to use ACE
functions. Though I do not know if it can be implemented using documented
ACE API.
