I thought this was covered earlier but could not find in the archives.
When I use SQL Assistnat to "show definition" of a very large View, part of the view is displayed and the remainder is not. It is sort of truncated or cut-off. This looks to me like a buffer size issue or answer set size issue, but I cannot find the option on how to increase the output size for SQL Assistant.
Sounds like you are using SQLA 13.10 and the 13.10 ODBC driver. There is an issue with the ODBC driver prior to the 13.10.05 release that causes this behavior. You can either update to the latest release of the ODBC driver or use the Teradata .NET Provider which does not exhibit this behavior.
