Q: 

Leading Zero is dropped when converting a csv file to data table using oledb

I have a csv file from which I have to populate different tables in database I am using Microsoft.Jet.OleDb.4.0 to convert csv file to data table from where I proceed forward

the problem is when I do this a value such as "0261" is stored as 261, the leading zero is dropped, is there a way to prevent it???

Thanks in advance...

A: 

If you store the value as a number, then there is no way to prevent it. All you can do is format the number in a report with leading zeros.

Another option is to store the number as four letter string (char(4)).

the data is not confined to a four letter string it may be as large as 10 digit

In that case, there is nothing you can do. Numbers in a database are always stored without leading zeros.

Or you can use `varchar(256)` :)

I found a solution just now I enclosed the number with double quotes after that it preserved 0s as it is now a string but the problem is it should be done where csv is genereated on which I dont have any control :(

A: 

Not possible to preserve zeros as numbers using oledb... wrote my own class to avoid using oledb and preserving zeros

If his answer helped, wouldn't it be better to accept his answer?

I used other ways to find my way through...
