Code

function testLikeEscape() {
  db_insert('test')
    ->fields(array(
      'name' => 'Ring_',
    ))
    ->execute();

  // Match both "Ringo" and "Ring_".
  $num_matches = db_select('test', 't')
    ->condition('name', 'Ring_', 'LIKE')
    ->countQuery()
    ->execute()
    ->fetchField();
  $this->assertIdentical($num_matches, '2', 'Found 2 records.');
  // Match only "Ring_" using a LIKE expression with no wildcards.
  $num_matches = db_select('test', 't')
    ->condition('name', db_like('Ring_'), 'LIKE')
    ->countQuery()
    ->execute()
    ->fetchField();
  $this->assertIdentical($num_matches, '1', 'Found 1 record.');
