Reusing Definitions with the INCLUDE Directive
Teradata PT allows the inclusion of object definitions from external files into a job script, and thus the use of these definitions in more than one script. For example, you can define a schema in a text file called customer.schema:
DEFINE SCHEMA
(
FirstName VARCHAR(32),
LastName VARCHAR(32),
...
);
Then, to include this schema definition in the job script:
DEFINE JOB CustomerUpdate
(
INCLUDE 'customer.schema';
DEFINE OPERATOR...
);
You can also use job variables (@<variableName>) in files declared by the INCLUDE statement. Assignment of values to job variables
takes place after the contents of the declared files have been incorporated into the
job script file, from the highest priority job variable source. For more information
on the various ways to set job variables and the processing priority for variable
sources, see “Setting Up Job Variables” on page 47.
