Hi,
This is an excerpt from the Dabo documentation in regard to the
DataStructure property:
"""Returns the structure of the cursor in a tuple of 6-tuples.
| 0: field alias (str)
| 1: data type code (str)
| 2: pk field (bool)
| 3: table name (str)
| 4: field name (str)
| 5: field scale (int or None)
This information will try to come from a few places, in
order:
1. The explicitly-set DataStructure property
2. The backend table method
"""
Resolution of your problem is to change your DataStructure type
from list to tuple type.
If you are extending DataStructure, instead of using
DataStructure.append((...))
use
DataStructure += ((...),)
