SELECT sde.st_area(zone) from sde.test1 ORDER BY name;//
SELECT shape from schools ORDER BY name;
SELECT objectid, sde.st_astext(SDE.ST_POINTfromSHAPE(shape,0)) AS points from schools;
SELECT name, sde.st_x (zone) "The X coordinate" from test ; //正确执行
SELECT name, sde.st_x (shape) "The X coordinate" from dijishi; //报错
//对于不是SQL语句生成的表格，比如shp文件import进来的，上面语句报错。SQL语句建立的表格空间字段为geometry，
而导入进去的表格shape字段也显示为geometry，但是同样的语句报错。
问题已解决，0表示用的spatial参数，spatial表名为st_spatial_references
