Question

I have a stored procedure that uses several input parameters and insert them into Sql Database. There is a problem with one parameter, @CustomerId, that is truncated (but not always) when inserted into database.

C#:

cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@CustomerId", Convert.ToInt32(customerId));
cmd.Connection = sqlConn;
sqlConn.Open();
cmd.ExecuteNonQuery();
sqlConn.Close();

Sql SP:
@CustomerId int

INSERT INTO dbo.tblOffers 
(CustomerId)
VALUES
    (@CustomerId)

sql table datatype:

CustomerId int not null

Example: 564276117 truncated to 4276117 (but its not happening all the time, and there are values greater than 560000000 that are inserted properly)
What am I doing wrong? Thanks

Answer 1

Try Parameters.Add() method instead of AddWithValue.

cmd.Parameters.Add("@CustomerId",SqlDbType.Int).Value=CustomerID;
