Oracle PL/SQL 函数 存储过程 使用ST_GEOMETRY

在esri网站上无意见看到一篇文章,写到在Oracle的函数或存储过程中使用ST_GEOMETRY函数的方法.

原文选段如下:

引用

All geometry operators, such as st_astext, st_centroid, st_numgeometries, etc. reside in the st_geometry_operators package. All relational operators, such as st_intersects, st_within, st_contains, etc. reside in the st_relation_operators package.


When referencing any st_* operator as a function, remember to include the _f clause after its name to reference the appropriate function in the package body.

即通过st_*_operator包和"_f"后缀,在PL/SQL相关的过程中,可使用ST_GEOMETRY的一些函数.
