 <p>A varbinary isn't displayed with an odd number of digits. The value contains a specific number of bytes, and each byte is displayed as two digits.</p> <p>(You can write a binary literal with an odd number of digits, for example <code>0x123</code>, but then it means the same things as <code>0x0123</code>.)</p> <p>As you copy a value that has 43679 digits, it's not a correct value from the database. Most likely it's because it gets concatenated, either when it is displayed or when you copy it.</p>
