2. 5 includes/database.inc \db_query()
3. 6 includes/database.mysql-common.inc \db_query()
4. 6 includes/database.pgsql.inc \db_query()
5. 7 includes/database/database.inc \db_query()

Runs a basic query in the active database.

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. Instead of a variable number of query arguments, you may also pass a single array containing the query arguments.

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.

Return value

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