How Do I Get Started?

You must perform various setup tasks to enable and use character set options.

Tasks 1 through 3 are required on all systems. Other tasks are optional, based on system needs.

  1. Make sure you understand how the Vantage system handles character data. See Character Sets and Object Names.
  2. Determine whether you can use system character set defaults or if you need to configure character set options. See System Default Character Support.
  3. Review the object naming topic to understand the rules that determine which characters are valid in object names for your system. See Object Names.
  4. Select and enable the client character sets that you need:
  5. If none of the Teradata-standard client character sets meets site needs, you can define a custom (site-defined) client character set:
  6. For information on default collation sequences and how to define and implement custom collation sequences, see Collation Sequences
  7. For detailed information on character conversion between client character sets and the server character set, including the option to define custom export widths for use during conversion to the client character set, see Character Conversion
