ZAMBIA,Zambian Kwacha,ZMW,967,2,

DESC := SUBSTR(vinput_rec, INSTR(vinput_file,',',1,1)+1);
can anyone help me please with the above kindlyIf str is a comma-delimited string, and you want to the first 3 characters after the N-th comma, then you can use
SUBSTR ( str
       , 1 + INSTR (str, ',', 1, n)
       , 3
       )Do you need to worry about not having 3 characters between the N-th comma and the next one? What if there are fewer than N commas?
I hope this answers your question.
If no, what is your question?
Does it involve reading a csv file that is not already in a table? Post a small sample file.
Does your qestion involve parsing strings that are already in a table? Post CREATE TABLE and INSERT statements.
In any case, post the exact results you want from the given data.
