Thread: sql server update picture in java swing

  1. #1

    Question sql server update picture in java swing

    Why when I update one row in the database, all the options are updated correctly, but the image of another row is edited.

    For example, I edit ID number 1, the date is edited correctly, but the photo of row 3 of the database is changed. But there is no change in the photo of row 1
    SQL SERVER Table
    ID	int	Unchecked
    Dates	date	Checked
    images	image	Checked

    Java Swing Code
     byte[] person_image = null;
    private void btnbrowsActionPerformed(java.awt.event.ActionEvent evt) {
