Test update queries involving LOB values.

Code

function testUpdateOneBlob() {
  $data = "This is\000a test.";
  $this->assertTrue(strlen($data) === 15, 'Test data contains a NULL.');
  $id = db_insert('test_one_blob')
    ->fields(array('blob1' => $data))
    ->execute();

  $data .= $data;
  db_update('test_one_blob')
    ->condition('id', $id)
    ->fields(array('blob1' => $data))
    ->execute();

  $r = db_query('SELECT * FROM {test_one_blob} WHERE id = :id', array(':id' => $id))->fetchAssoc();
  $this->assertTrue($r['blob1'] === $data, format_string('Can update a blob: id @id, @data.', array('@id' => $id, '@data' => serialize($r))));
