Enhance `Cursor.description` with type information #297

Closed mdesmet closed 1 year ago

mdesmet commented 1 year ago

Description

Add internal_size, precision, scale to Cursor.description to make it easier to get type information of a result set.

Note that if this information can be extracted from the type, this is also removed from the type_code, making it easier to match on.

Non-technical explanation

This can be looked at again after PARAMETRIC_DATETIME is merged as now no type information is exposed for temporal types.
