Thanks for your suggestion.

Debugging code is giving same uid as 02357092887

Thanks sir for your reply. But after casting NVARCHAR column into a BIGINT, it shows error- Arithmetic overflow error converting nvarchar to data type numeric.

I have a NUM column (first column of database) in my database which is of BIGINIT type. I think it is showing error when reader starts reading values from database, it is getting the numeric value for NUM column with NVARCHAR column of uid because if I am writing SQL query for selected fields as - select uid,name
