混亂的Oracle 11g空間數據庫SDO_RELATE anyintersect

Question

我運行中的Oracle 11g以下querys：

1）select a1.apid from access_point a1 where sdo_relate(a1.shape,a1.shape,'mask=equal') = 'TRUE' and a1.apid = 'a5vhe';

2）select a1.apid from access_point a1 where sdo_relate(a1.shape,a1.shape,'mask=anyintersect') = 'TRUE' and a1.apid = 'a5vhe';

現在的Oracle 11g文檔定義掩模 'anyintersect' 爲「 ANYINTERACT：如果對象不相交，則返回TRUE。「那麼爲什麼oracle爲我的查詢1返回記錄a1併爲QUERY2返回none？

Answer 1

你有一個錯字。

• 不正確的：sdo_relate(a1.shape,a1.shape,'mask=anyintersect')
• 正確：sdo_relate(a1.shape,a1.shape,'mask=anyinteract')
