Definition

db_query($query)

Description

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.

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.

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.

Return value

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