To change the data type default formats, you must create a specification for data formatting (SDF) file, and then use the tdlocaledef utility. For more information, see Teradata Vantage™ - Database Utilities , B035-1102 .
Teradata Database uses the changes when it assigns formats to columns of new tables where the CREATE TABLE statement does not explicitly specify the column format. Columns of tables that were created prior to changing the default formats continue to use the format that Teradata Database assigned to the column at the time the table was created.
To view the settings of the preceding data type default formats for the current session, use the HELP SESSION statement. For more information, see “HELP” and “SHOW” in Teradata Vantage™ - SQL Data Definition Language Syntax and Examples, B035-1144.
