In the second form, if <i>[database-name.]table/index-name</i> identifies a table,then all indicesassociated with the table are rebuilt. If an index is identified, then onlythis specific index is deleted and recreated.</p><p>If no <i>database-name</i> is specified and there exists both a table orindex and a collation sequence of the specified name, then indices associatedwith the collation sequence only are reconstructed. This ambiguity may bedispelled by always specifying a <i>database-name</i> when reindexing aspecific table or index.<hr><small<i>This page last modified 2007/12/20 21:09:25 UTC</i></small></div></body></html>⌨️ 快捷键说明
