Runs a limited-range query in the active database.

Use this as a substitute for db_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.

...: A variable number of arguments which are substituted into the query using printf() syntax. The query arguments can be enclosed in one array instead. Valid %-modifiers are: %s, %d, %f, %b (binary data, do not enclose in '') and %%.

NOTE: using this syntax will cast NULL and FALSE values to decimal 0, and TRUE values to decimal 1.

$from: The first result row to return.

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

Return value

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