+ - The first one (wxDbColInf *wxDb::GetColumns(wxChar *tableName[], const
+ wxChar* userID)) calls the second implementation for each separate table
+ before merging the results. This makes the code easier to maintain as
+ only one member (the second) makes the real work
+ - wxDbColInf *wxDb::GetColumns(const wxString &tableName, int *numCols, const

+ - It doesn't anymore rely on the type-name to find out which database-type
+ each column has
+ - It ends by sorting the columns, so that they are returned in the same
