Tested the creation of index info from MySQL SQLQuery and found some issues.

Line 222:

      if IsPublishedProp(DataSet, 'ServerIndexDefs') then
        IndexDefs := GetObjectProp(DataSet, 'ServerIndexDefs') as

IndexDefs isn't the same as ServerIndexDefs for TCustomSQLQuery. IndexDefs
just returns one index 'DEFAULT_ORDER' which isn't exported.

Line 252

              UTF8Decode(StringReplace(Index.Fields, ';', ' ',
              [rfReplaceAll, rfIgnoreCase])));

Typo: Index.Fields instead of Index.Name.

After these changes, import in access 2002 and 2010 is ok. Multiple field
indices is working also?

I also noticed that the mysql implementation in fcl-db doesn't support index
collation (ascending-descending). PostGres at first sight neither and oracle
doesn't even support indices, in fcl-db I mean :(
Admittedly the definition of TIndexDef with DescFields string property that
supposedly lists the descending fields, isn't facilitating sort order
support neither.
