Create and save a Teradata MultiLoad job script file named insert.mload that loads the six-record insert.data file into the Employee table:

.logtable inslogtable;
.logon tdpid/username,password;

CREATE TABLE employee (
    EmpNo SMALLINT FORMAT ‘9(5)’ BETWEEN 10001 AND 32001 NOT NULL,
    Name VARCHAR(12),
    DeptNo SMALLINT FORMAT ‘999’ BETWEEN 100 AND 900 ,
    PhoneNo SMALLINT FORMAT ‘9999’ BETWEEN 1000 AND 9999,
    JobTitle VARCHAR(12),

    UNIQUE PRIMARY INDEX( EmpNo )
    INDEX( Name );

Comments

  1. For syntax and descriptions of the following Teradata MultiLoad utility commands used in the preceding example, see Teradata MultiLoad Commands.
    • BEGIN MLOAD
    • BEGIN MLOAD
    • DML LABEL
    • END MLOAD
    • FIELD
    • IMPORT
    • LAYOUT
    • LOGOFF
    • LOGON
    • LOGTABLE
  2. The CREATE TABLE statement creates a new table on Teradata Database:
    • Named employee
    • Containing the following columns:

      - DeptNo

      - DOB

      - EdLev

      - EmpNo

      - HCap

      - JobTitle

      - MStat

      - Name

      - PhoneNo

      - Race

      - Salary

      - Sex

      - YrsExp

    • Indexed by:

      - EmpNo (UNIQUE PRIMARY)

      - Name

      For a description of the CREATE TABLE statement, see SQL Data Definition Language.

  3. The LAYOUT command and the series of FIELD commands specify each field of the data records that are sent to Teradata Database. (The insert.input data file created in Creating the Source Data File.)

    The specified layout name, inslayout, is referenced in the subsequent Teradata MultiLoad IMPORT command.

    Each FIELD command specifies the name, starting position, and data type description for each field in the input data records. In making the field declarations, note that the 1-character and multi-character delimiter fields are optional. They are not required in the example.

  4. The DML LABEL command introduces the INSERT statement.
  5. The IMPORT command starts the import task, using the insert.input file and the insdml insert statement.
