function drupal_get_schema in Drupal 7

Same name and namespace in other branches

1. 6 includes/common.inc \drupal_get_schema()

Gets the schema definition of a table, or the whole database schema.

The returned schema will include any modifications made by any module that implements hook_schema_alter(). To get the schema without modifications, use drupal_get_schema_unprocessed().

Parameters

$table: The name of the table. If not given, the schema of all tables is returned.

$rebuild: If true, the schema will be rebuilt instead of retrieved from the cache.
