drupal_uninstall_schema

Remove all tables that a module defines in its hook_schema().

Note: This function does not pass the module's schema through hook_schema_alter(). The module's tables will be created exactly as the module defines them.

Parameters

$module: The module for which the tables will be removed.

Return value

An array of arrays with the following key/value pairs:

• success: a boolean indicating whether the query succeeded.
• query: the SQL query(s) executed, passed through check_plain().
