One or more phrases that define the data type for the column. For a list of data types you can specify, see Data Types Syntax.
You must specify a single data type for each column_name , except for those defined in a CREATE TABLE … AS request, where you cannot specify data types.
You must define the data type before you specify attributes. Column data attribute specifications are optional.
If you do not specify explicit formatting, a column assumes the default format for the data type. The default format can be specified by a custom data formatting specification (SDF) defined by the tdlocaledef utility. See Teradata Vantage™ - Database Utilities , B035-1102 . Explicit formatting applies to the parsing and to the retrieval of character strings.
