ODBC issues

• I am browsing MS SQL Server dynasets. When I am using CGXDynamicRecordset and add new rows, I get an assertion. Is this is a known problem?
  
  
• Can I change the query for a grid at runtime?
  
  
• When I bind Objective Grid to a SQL server database with a text field all the other fields show up as expected but the text field shows up without any data.
  
  
• Optimize browsing large SQL Server or Oracle recordsets by using dynamic cursors
