Reading Teradata TPump Error Tables
Interpreting Error Table Information
The following Teradata TPump task describes how to interpret the error table information to
isolate and fix the problem. This task is greatly abbreviated, containing only the DML
command and the IMPORT command. A probable sequence of actions for locating and fixing
the problem follows the task.
SEQ TYPE SEQ # Statement
-------- --- -------------------------------------------------------
DML 001 .DML LABEL FIRSTDML;
STMT 001 INSERT INTO table1 VALUES( :FIELD1, :FIELD2 );
STMT 002 UPDATE table2 SET field3 = :FIELD3 WHERE field4 =:FIELD4;
DML 002 .DML LABEL SECNDDML;
STMT 001 DELETE FROM table3 WHERE field3 = :FIELD3;
IMPORT 001 .IMPORT INFILE file1 LAYOUT layout1
APPLY 001 APPLY FIRSTDML;
IMPORT 002 .IMPORT INFILE file2 LAYOUT layout2
APPLY 001 APPLY FIRSTDML
APPLY 002 APPLY SECNDDML;
In this example, the Statement column represents the user entry. The SEQ # and SEQ TYPE
columns are the Sequence Number and Sequence Type assigned to each statement. If an error
occurs while using this task and the information in the following error table is displayed,
where the error occurred and what was being executed at the time of the error can be
determined.
ImportSeq DMLSeq SMTSeq ApplySeq SourceSeq DBCErrorCode DBCErrorField
--- --- --- --- --------- ----- ------------
002 001 002 001 20456 2679 field3
The following sequence provides a series of analytical steps for extracting and interpreting the
information in this row of the error table.
1 Check the DMLSeq field to find the statement being executed. It contains the sequence
number 001.
2 Check the SMTSeq field. The sequence number 002 in this field indicates that the error
occurred while executing: change this statement of the first DML command, which is the
UPDATE statement in the above task.
3 Verify that the script shows that the DML command is used twice, once in each IMPORT.
4 The value of 002 in the ImportSeq field shows that the error occurred in the second
IMPORT clause.
5 The value of 001 in the ApplySeq field indicates that the error occurred in the first apply of
that clause, which was being executed when the error occurred.
6 The value of 2679 in the DBCErrorCode field shows:
The format or data contains a bad character
which indicates that bad data is coming from the client.
