If a column name from a source table is a Teradata PT reserved word, the Teradata PT Wizard appends the phrase “_#” (where # is a numeric) so that the name differs from the keyword and the submitted script does not receive a syntax error.
For example, if the keyword DESCRIPTION is used as a column name, the name is changed to DESCRIPTION_1. Teradata PT keeps an internal counter for generating the appended number.
For the complete list of Teradata PT reserved words, see Teradata Parallel Transporter Reference (B035-2436).
The values under TPT Type are names of the data types associated with the Teradata PT columns. The values under DBS Type are the data types from the source database. When Teradata PT gets a column name from a source table, it looks at the definition schema of the table to determine an accurate data type. Sometimes these types can be recorded incorrectly or as a “?” when the Wizard cannot properly determine the data type. This often occurs when reading user-defined data types (UDTs).
To change or correct a Teradata PT data type, click Edit Type (or right-click), and select the correct data type from the shortcut menu. Enter the length, precision, and scale if applicable. The precision and scale data types are only available when Decimal/Numeric is selected.
