in excel file there are 5 columns in that center one(3rd column) is my primary key.
if i want to send the datas to DATABASE using dynamic schema, how can i do this
note: the position of primary key should not be changed , it should be at center
i can able to do this job with primary key at last position and first position, but i want to know how to do this when my primary key at the center position
You just have to tick the key checkbox for which so ever you want to specify as a primary key even though if it is dynamic schema, refer the pic .You can keep the previous one too i.e rollno, and it reflects at the same position only.
thanks for the reply, but here, in your image all the column are in different datatypes like int, string but i want the left side of the tmap have one column and it should be of dynamic type
