in a BTEQ we have 2 insert 2 del 2 update statment.
when the BTEQ is restarted i need to run the BTEQ from
after DEL statment(means no need to run the insert & del
stat).what is the logic for the above requirement?
Answer Posted / 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
