I cannot get the source table from an ADO field object in Matlab. Here's a quickie code explanation:
>> dbconn = actxserver('ADODB.connection');
>> dbconn.Open(connString);
>> rs = dbconn.Execute(sql);
>> fld = rs.Field.Item(0);
>> prop = fld.Properties('BASETABLENAME');
>> prop.Value
>> prop.Type
ans = NaN
ans = 'adVarWChar'
regardless of the type of query or field I grab, the BASETABLENAME and BASECOLUMNNAME properties always com out to be NaN's. I'm using Matlab 2010b. My hunch is that Matlab is unable to convert adVarWChar to a char, but not posisitive on this. My source issue is obtaining the source table of any given field in a recordset. Any help is appreciated.
