/**
* Read from the database using a filter array.
*
* The standard function to perform reads was db_query(), and for static
* queries, it still is.
*
* db_query() used an SQL query with placeholders and arguments as parameters.
*
* Drupal DBTNG provides an abstracted interface that will work with a wide
* variety of database engines.
*
* db_query() is deprecated except when doing a static query. The following is
* perfectly acceptable in Drupal 8. See
* @link http://drupal.org/node/310072 the handbook page on static queries @endlink
*
* @code
* // SELECT * FROM {dbtng_example} WHERE uid = 0 AND name = 'John'
* db_query(
* "SELECT * FROM {dbtng_example} WHERE uid = :uid and name = :name",
* array(':uid' => 0, ':name' => 'John')
* )->execute();
* @endcode
*
* But for more dynamic queries, Drupal provides the db_select()
* API method, so there are several ways to perform the same SQL query. See
* the
* @link http://drupal.org/node/310075 handbook page on dynamic queries. @endlink
* @code
* // SELECT * FROM {dbtng_example} WHERE uid = 0 AND name = 'John'
* db_select('dbtng_example')
* ->fields('dbtng_example')
* ->condition('uid', 0)
* ->condition('name', 'John')
* ->execute();
* @endcode
*
* Here is db_select with named placeholders:
* @code
* // SELECT * FROM {dbtng_example} WHERE uid = 0 AND name = 'John'
* $arguments = array(':name' => 'John', ':uid' => 0);
* db_select('dbtng_example')
* ->fields('dbtng_example')
* ->where('uid = :uid AND name = :name', $arguments)
* ->execute();
* @endcode
*
* Conditions are stacked and evaluated as AND and OR depending on the type of
* query. For more information, read the conditional queries handbook page at:
* http://drupal.org/node/310086
*
* The condition argument is an 'equal' evaluation by default, but this can be
* altered:
* @code
* // SELECT * FROM {dbtng_example} WHERE age > 18
* db_select('dbtng_example')
* ->fields('dbtng_example')
* ->condition('age', 18, '>')
* ->execute();
* @endcode
*
* @param array $entry
* An array containing all the fields used to search the entries in the
* table.
*
* @return object
* An object containing the loaded entries if found.
*
* @see db_select()
* @see db_query()
* @see http://drupal.org/node/310072
* @see http://drupal.org/node/310075
