title: Storing byte array in HTML5 sqlite database
body: <p>I am working on an offline capable mobile web app and need to store large amounts of raw byte data in a HTML5 database.  I want to store them as compact as possible, so a joined string is not an option. Here is a sample code that creates a db, table, inserts data and retrieves it again. </p>
  
  <p>Example:</p>
  
  <pre><code>var bytes=[97, 0, 6, 244, 98, 66, 76, 65, 131, 5, 7, 142, 81, 184, 112, 33];
  
  openDatabase('_test_', 1.0, '_test-', 5000).transaction(function(tx) {
  tx.executeSql("DROP TABLE IF EXISTS MYTABLE", [], function(){
  tx.executeSql("CREATE TABLE IF NOT EXISTS MYTABLE(content BLOB);",[],function(){
  tx.executeSql("INSERT INTO MYTABLE values(?)", [bytes], 
      function()
      {
          tx.executeSql("SELECT * FROM MYTABLE ", [], function(transaction, results)
          {
              console.log(results.rows.item(0))
          });
  },function(transaction, error){console.log(error)})
  },function(transaction, error){console.log(error)})
  })
  })
  </code></pre>
  
  <p>I am  trying to store the array as is, which actually saves as a joined string :"97, 0, 6, 244, 98, 66, 76, 65, 131, 5, 7, 142, 81, 184, 112, 33". Not what I need since it will be way too large.</p>
  
  <p>I am converting the array into a string now:</p>
  
  <pre><code>openDatabase('_test_', 1.0, '_test-', 5000).transaction(function(tx) {
  tx.executeSql("DROP TABLE IF EXISTS MYTABLE", [], function(){
  tx.executeSql("CREATE TABLE IF NOT EXISTS MYTABLE(content BLOB); ", [], function(){
  tx.executeSql("INSERT INTO MYTABLE values(?)", [s], 
      function()
      {
          tx.executeSql("SELECT * FROM MYTABLE ", [], function(transaction, results)
          {
              console.log(results.rows.item(0))
          });
  },function(transaction, error){console.log(error)})
  },function(transaction, error){console.log(error)})
  })
  })
  </code></pre>
  
  <p>What the DB now returns is simply "a".</p>
  
  <p>So my question is how do I serialize a javascript byte array in HTML5 database without resorting to a joined string? </p>
