Re: [Zope] Resolving nvarchar fields via ZmxODBCDA
It fails under ZmxODBC the following example shows how to convert the nvarchar fields to char type fields within an SQL query so that ZmxODBC can deal with them:
SELECT table_catalog = CONVERT(char(30),table_catalog), table_name = CONVERT(char(30),table_name), column_name = CONVERT(char(30),column_name), data_type = CONVERT(char(30),data_type) FROM INFORMATION_SCHEMA.COLUMNS where column_name like <dtml-sqlvar search_string type=string> order by ordinal_position The same technique should apply to other unsupported types.
This works ok. But Meanwhile I've seen other problems: -There are problems also with TimeStamp/smalldatetime, and even a convert to char(x) still gives an InternalError. -And if a column returns null,i.e, the field is empty, then there is also an InternalError(I remember this null problem was mentioned in the past by the author of zmxodbc).
