title: Compare images stored in mysql db
body: <p>I know I can store images in mysql as data type blob. Wandering if i can compare the blob values in my query? </p>
  
  <p>E.g. select answer from mtTable where imageBlobValue = image010. </p>
  
  <p>Here imageBlobValue and image010 data type is blob. </p>
  
  <p>TIA</p>
