我一直在使用MBRWithin功能很多次.突然我注意到谷歌地图这POINT(101.11857 4.34475)是我指定的地理围栏,但它仍然在mysql中给出值1任何原因或需要调整？

SELECT MBRWithin(GeomFromText('POINT(101.11857 4.34475)'),GeomFromText('POLYGON((101.12112522125244 4.3531723687957164,101.11846446990967 4.351417913665312,101.13138198852539 4.336397898951581,101.13477230072021 4.33211863778494,101.14065170288086 4.321933898868271,101.14992141723633 4.306699328215635,101.15455627441406 4.30978050198082,101.1397933959961 4.334600612212089,101.12112522125244 4.3531723687957164,101.12112522125244 4.3531723687957164))')) As geoFenceStatus

我有以下功能被添加到mysql数据库我已经通过phpMyAdmin尝试它,但它没有给我任何指示是否添加和当我尝试运行该函数时给出错误该函数不存在.我在这里缺少什么？
