public function DatabaseConnection_pgsql::queryRange in Drupal 7

Runs a limited-range query on this database object.

Use this as a substitute for ->query() when a subset of the query is to be returned. User-supplied arguments to the query should be passed in as separate parameters so that they can be properly escaped to avoid SQL injection attacks.

Parameters

$query: A string containing an SQL query.

$args: An array of values to substitute into the query at placeholder markers.

$from: The first result row to return.

$count: The maximum number of result rows to return.

$options: An array of options on the query.

Return value

DatabaseStatementInterface A database query result resource, or NULL if the query was not executed correctly.
