Question

I have written code to insert an Image in SQL server but it throws an exception:

String or binary data would be truncated. The statement has been terminated.

Here is my Code for insert image:

FileStream imageStream = new FileStream(CvVariables.IMAGE_PATH, FileMode.Open, FileAccess.Read);
int fileLangth = (int)imageStream.Length;
byte[] imageInBytes = new byte[fileLangth];
imageStream.Read(imageInBytes, 0, (int)fileLangth);
Cv_Customer_Information addNewCustomer = new Cv_Customer_Information
{
      UserID = this.NewCustomerTextUserName.Text,
      UserImage =new System.Data.Linq.Binary(imageInBytes),
      Date = this.NewCustomerDate.SelectedDate.ToString(),
      Name = this.NewCustomerTextBoxName.Text,
      Phone = this.NewCustomerTextBoxPhone.Text,
      Email = this.NewCustomerTextBoxEmail.Text,
      NationalID = this.NewCustomerTextBoxNationalID.Text,
      Address = this.NewCustomerTextBoxAddress.Text
};
singupDataContext.Cv_Customer_Informations.InsertOnSubmit(addNewCustomer);
singupDataContext.SubmitChanges();

I also don`t understand how to retrieve images from SQL Server?

update: I use image Data Type in UserImage field and I am working with WPF

Answer 1

Well, this error means that the data of one of your fields (string or binary) is longer than the database definition of the column in which it will be stored.

This can be for example your username. If the database is a varchar(8) and you try to assign a name of 10 characters, you will get this error.

From the errormessage you cannot deduct what field is causing the error. It can be any string or your Binary data. Crosschek the input with the database definition to find the field/columns that is causing the error.

Solution: provide smaller data or increase the length in the database.
