Suppose that table_1 has three columns named cunicode, csjis, and clatin with the respective corresponding repertoires UNICODE, KANJISJIS, and LATIN. Suppose further that the current client character set is KanjiEUC.
If you submit the following statement, then the data from all columns will arrive into the application in the KanjiEUC form-of-use.
SELECT cunicode, csjis, clatin FROM table_1;
Because of this, the application should use variables declared as mixed single-byte character/multibyte character strings in order to store the data from the Teradata Database.
