Teradata truncating character fields when updated from Access
Posted on 2007-11-29
I'm trying to run a simple append query in Microsoft Access. The query selects 3 character fields in a local table and appends them to a linked table (via ODBC) on a Teradata server - no where clause, conditionals, or data transformation. The structure of the fields in the linked table is equivalent to that of the local table, as far as I can tell. Local table has text fields of length 11, 15, and 15 characters; Teradata table has corresponding Varchar fields of length 11, 15, and 15.
The query completes successfully... but the resulting data in the Teradata table is truncated to half of the character length of the field. For example, a text value 'Enterprise' in the first field in the local table is stored in the Teradata table as 'Enter'. This is consistent for all the character fields. I tried an integer field as a test; this appears to append successfully without any truncation.
Is there some encoding issue I need to be aware of when moving data between MS-Access and Teradata?
