ArcSDE10.2.2执行ST_Geometry时报ORA-20006
问题描述：ArcSDE 10.2.2执行ST_Geometry的ST_ASTEXT操作符，将Geometry对象转换为WTK串，如果数据量比较大，比如我测试的数据打出超过1000条数据时，系统会报ORA-20006错误。
ORA-20006: Error generating text from shape (-1)
ORA-06512: 在 "SDE.ST_GEOMETRY_SHAPELIB_PKG", line 67
ORA-06512: 在 "SDE.ST_GEOMETRY_OPERATORS", line 118

经过与美国Support的沟通，认定为一个Bug，该问题将在ArcGIS10.3版本解决。
[#NIM099098 The ST_AsText SQL function is failing when the result set contains more that one record and NumPoints is ~2000 (or more)..]
The issue is resolved in 10.3.
