Extended Object Names in the .NET Data Provider

In Teradata Database Release 14.10 object names have been lengthened from 30 bytes of a Latin or KANJISJIS character set to 128 Unicode characters.

While using a session character set that may contain limitations due to the supported set of characters, Unicode delimited identifiers are supported in all SQL text statements. Please see the SQL Data Types and Literals manual for information on Unicode delimited identifiers.
