Class

DatabaseSelectComplexTestCase

Test more complex select statements.

Code

function testNestedConditions() {

  // This query should translate to:
  // "SELECT job FROM {test} WHERE name = 'Paul' AND (age = 26 OR age = 27)"
  // That should find only one record. Yes it's a non-optimal way of writing
  // that query but that's not the point!
  $query = db_select('test');
  $query
    ->addField('test', 'job');
  $query
    ->condition('name', 'Paul');
  $query
    ->condition(db_or()
    ->condition('age', 26)
    ->condition('age', 27));
  $job = $query
    ->execute()
    ->fetchField();
  $this
    ->assertEqual($job, 'Songwriter', 'Correct data retrieved.');
}
