Answer Posted / 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
