HSODBC and ORA-01002

Question

Hi, guys!
Why in this PL/SQL code "COMMIT;" comand causes an error ORA-01002 ?
I use Microsift ODBC driver for Visual FoxPro.
DECLARE
TYPE EmpCurTyp IS REF CURSOR ;
emp_cv EmpCurTyp;
emp_new EmpCurTyp;
tab_name VARCHAR2(30);
D2 varchar(3);
BEGIN
OPEN emp_cv FOR 'select table_name T_N from [email protected]' ;
LOOP
FETCH emp_cv INTO tab_name;
EXIT WHEN emp_cv%NOTFOUND;
OPEN emp_new FOR 'select "ko" D2 from '| |tab_name| |'@ho.world ' ;
LOOP
FETCH emp_new INTO D2;
commit; -- << causes an error ORA-01002 fetch out of sequence
EXIT WHEN emp_new%NOTFOUND;
END LOOP;
ClOSE emp_new;
END LOOP;
CLOSE emp_cv;
END;
Thanks.

Thanks for the suggestion
There are no "char(32767)"s in the package - altho there are "varchar2(32767)"s
I have tried a variotion on the script, outputting the result to a new table instead of updating the enrolment - which ran fine so the error is in the update.
I tried adding a step using the result in the temp table to update the enrolment table - and got my errors again. So there is something funny in my data. Nothing obvious shows.
The full temp table contains 745292 records - when it failed 150 records had been written.
I note that although I had expected only to find one record per enrolment, there are some where there are two (@#$%!! source system writing two "insert" audit records) - could my problem be that I am updating a record previously updated - where do I set the script to commit as it goes?
