#89 Custom SQL for table column listing.

[Todamok]

Hi,

I'd like to see support for custom SQL to harvest information on columns in a :table. Similar to selectTablesSql, selectTableCommentsSql and other properties.
I have a database I can connect to only via JDBC-ODBC bridge (Ingres 9.2). I can get a list of schemas and tables (my own override) but SchemaSpy fails with:
net.sourceforge.schemaspy.model.Table$1ColumnInitializationFailure: Failed to collect column details for table 'aaa' in schema 'yyy'.
I could work around almost any driver shortcomming with SQL override.

Regards,
Luke
