The DEFINE SCHEMA statement describes the structure of the data source or data target with an ordered set of column definitions. Each column definition consists of a column name and a Teradata PT data type identifier.

Some data types require additional defining attributes, such as lengthBytes for character data types and precision for data types with fractional seconds, such as TIME, TIMESTAMP, and some INTERVAL and PERIOD data types.

A job script can contain multiple schemas, and a schema can be used with multiple operators, as long as it accurately describes the data processed by each operator.
