原因:

ArcSDE空间SQL要求Polygon点串坐标的第一个点的X，Y坐标需要和最后一个点的X，Y坐标的坐标需要一致。

解决方法:

select SDE.ST_GEOMETRY (‘POLYGON ((503433.822 294306.924, 503514.177 294339.956, 503531.789 294297.311, 503524.894294272.889, 503481.474 294257.951, 503450.539 294265.595, 503433.794 294306.914, 503433.822294306.924))’,2436) from dual;
