Hi: How can i install a table in mysql. I tried with this script but don't work. function tags_schema() { $schema['table'] = array( 'description' => t('The base table for nodes.'), 'fields' => array( 'nid' => array( 'description' => t('The primary identifier for a node.'), 'type' => 'serial', 'unsigned' => TRUE, 'not null' => TRUE), 'vid' => array( 'description' => t('The current {node_revisions}.vid version identifier.'), 'type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'default' => 0), 'type' => array( 'description' => t('The {node_type} of this node.'), 'type' => 'varchar', 'length' => 32, 'not null' => TRUE, 'default' => ''), 'title' => array( 'description' => t('The title of this node, always treated a non-markup plain text.'), 'type' => 'varchar', 'length' => 255, 'not null' => TRUE, 'default' => ''), ), 'indexes' => array( 'node_changed' => array('changed'), 'node_created' => array('created'), ), 'unique keys' => array( 'nid_vid' => array('nid', 'vid'), 'vid' => array('vid') ), 'primary key' => array('nid'), ); } function tags_install() { // Crea mi tabla drupal_install_schema('tags'); } function tags_uninstall() { // Borra mi tabla drupal_uninstall_schema('tags'); } ?>
