Chapter 3: Teradata TPump Commands TABLE TABLE Purpose The TABLE command identifies a table whose column names and data descriptions are used as the names and data descriptions of the input record fields. These are assigned in the order defined. The TABLE command must be used with the LAYOUT command. Syntax .TABLE tableref ; 3021A035 where Syntax Element tableref Description Existing table whose column names and data descriptions are assigned, in the order defined, to fields of the input data records The column names of the table specified by the TABLE command must be Teradata SQL column names that do not require being enclosed in quotation marks. Tables cannot be created with invalid column names. Any nonstandard column name causes one of three kinds of errors, depending on the nature of the divergence from the standard. These errors are: • Embedded blanks cause a syntax error, depending on the non-blank contents of the name. • Invalid characters cause an invalid name error. • Reserved words cause a syntax error that mentions invalid use of the reserved word. Usage Notes One or more TABLE commands may be intermixed with the FIELD command or FILLER command following a LAYOUT command. This method of specifying record layout fields assumes each field, as defined by the data description of the corresponding column of tableref, is contiguous with the previous one, beginning at the next available character position beyond any previous field specifications for the input records. The fields must appear in the order defined for the columns of the table. The object identified by the tableref parameter must be a table. It need not appear as a parameter of the BEGIN LOAD command, but the user must either be an owner of the object or have at least one privilege on it. If specified as an unqualified table name, the current default database qualifies it. 186 Teradata Parallel Data Pump Reference
Chapter 3: Teradata TPump Commands TABLE When serialization has been set to ON by the BEGIN LOAD command, the primary index columns for the specified table are considered key fields for serialization purposes. When the TABLE command is used and the table contains a structured UDT type, Teradata TPump returns an external representation of the UDT and that requires the user to transform. The term “external type” means the data type of the external opaque container for a structured UDT and is the type returned by the from-sql transform method. Teradata Parallel Data Pump Reference 187
