Answer / yuvaevergreen

Adding to above,assuming usage of a simple restart table,
below logic can be used. Below sql will not take care of
insert or delete statement failure. If the update statement
fails, the script would be restarted from update statement.
If the insert or delete statements fail, the script
would be started from insert statement.

bteq << EOF

.logon tdpid/user,password;

SELECT * FROM RESTART_TABLE WHERE STATUS='RESTART';
IF .ACTIVITYCOUNT=1 THEN .GOTO UPDTDML;
IF .ACTIVITYCOUNT=0 THEN .GOTO INSDML;

.label INSDML;
INSERT STATEMENT;

.IF ERRORCODE <> 0 THEN .EXIT;

.label DELDML;
DELETE STATEMENT;

.IF ERRORCODE <> 0 THEN .EXIT;

.LABEL UPDTDML;
UPDATE STATEMENT;

.IF ERRORCODE <> 0 THEN .GO TO REST;

.IF ERRORCODE = 0 THEN .GO TO REST1;

.LABEL REST;
DEL FROM RESTART_TABLE;
INSERT INTO RESTART_TABLE ('RESTART');
.EXIT;

.LABEL REST1;
DEL FROM RESTART_TABLE;
.EXIT;

.EOF

Answer / aarsh dave

Create an empty file before each set of DML statements.
Write the BTEQ as below:

bteq << EOF

.logon tdpid/user,password;

.OS if [-f bteq_restart.txt];then else {touch bteq_restart.txt};

.run file bteq_restart.txt;

.label INSDML;

INSERT STATEMENT 1;

INSERT STATEMENT 2;

.IF ERRORCODE <> 0 THEN .EXIT ERRORCODE;

.label DELDML;

DELETE STATEMENT 1;

DELETE STATEMENT 2;

.IF ERRORCODE <> 0 THEN .EXIT ERRORCODE;

.IF ERRORCODE <> 0 THEN .OS echo '.GOTO UPDTDML' >
bteq_restart.txt;

.LABEL UPDTDML;

UPDATE STATEMENT 1;

UPDATE STATEMENT 2;

.IF ERRORCODE <> 0 THEN .EXIT ERRORCODE;

.OS rm -f bteq_restart.txt;

.EOF
