Teradata Parallel Data Pump

Chapter 3: Teradata TPump Commands
IMPORT
APPLY Example
• NOSTOP
If NOSTOP is specified, Teradata TPump will not terminate even if an error is encountered.
By specifying both options and redirecting STDERR to a file location instead of the terminal
screen, the Teradata TPump job runs to completion and saves all the error records. Then the
error records can be manually modified and loaded into the table.
All IMPORT commands for a Teradata TPump task must appear between the BEGIN LOAD
and END LOAD commands for the task.
Teradata TPump imposes several syntax rules for the parms string for an INMOD user exit
routine. On entry to any INMOD user exit routine for Teradata TPump, the conventional
parameter register points to a parameter list of two 32-bit addresses used to communicate
with the INMOD.
At the end of an IMPORT, an environmental variable is established for each DML command
executed. Teradata TPump variables are not constrained to 30 characters. These variables
contain the activity counts associated with each statement. The variables created are of the
form:
&IMP __
where
n = the number of the IMPORT, from one through four.
Apply label = the label of the clause containing the DML command in question.
x = the number of the statement within the containing APPLY clause.
The following script is an example of a Teradata TPump job using the APPLY keyword to
create conditional clauses to apply DML INSERTs, UPDATEs, and UPSERTs to the IMPORT.
.BEGIN LOAD SESSIONS 34;
.LAYOUT EQTTB535;
.FIELD Pool_Upd_Code * CHAR(01);
.FIELD Eqmt_Init
* CHAR(04);
