function db_query
7.x database.inc | db_query($query, array |
6.x database.pgsql.inc | db_query($query) |
6.x database.mysql-common.inc | db_query($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
Successful SELECT, SHOW, DESCRIBE, EXPLAIN, or other queries which return a set of results will return a database query result resource. Other successful queries will return TRUE and failing queries will return FALSE.
