Question

scenario:
I have a database having a record 001234 and I am calling it with cmd.executescaler(); into a int variable. The problem is when I retrieve the saved data (001234) data from that variable it gives only 1234. 00 in 001234 are important, this was the problem first coming in db where sql omits the first zero’s then I changed the datatype to nvarchar which works, how I can retrieve the data on the form exactly 001234.

Note: I cannot take the data into string as I have to also apply some calculations on them.

using Sql Server visual studio 2010 c#

Hope it is clear not vague. If you need more information tell me.
Thanks in advance.

If those leading zeros have some meaning and can’t be left out, conversion can be done:

            int number = 0;
            string strNumber = (string)cmd.ExecuteScalar();
            if(int.TryParse(strNumber, out number))
            {
                // process number

                // if you want some output to be formatted with leading 
                // zeros you can use PadLeft method
                int totalNumberOfDigits = 6;
                string strResult = number.ToString().PadLeft(totalNumberOfDigits, '0');
            }
