我想使用cx_Oracle的cursor.callfunc()调用Oracle函数返回一个对象。但这不起作用
在这里你可以看到我的代码:
import cx_Oracle
import json
import web
urls = (
"/", "index",
"/grid", "grid",
)
app = web.application(urls, globals(),web.profiler )
web.config.debug = True
connection = cx_Oracle.Connection("TEST_3D/limo1013@10.40.33.160:1521/sdetest")
typeObj = connection.gettype("MDSYS.SDO_GEOMETRY")
class index:
def GET(self):
return "hallo moritz "
class grid:
def GET(self):
web.header('Access-Control-Allow-Origin', '*')
web.header('Access-Control-Allow-Credentials', 'true')
web.header('Content-Type', 'application/json')
cursor = connection.cursor()
cursor.arraysize = 10000 # default = 50
cursor.execute("""SELECT a.id AS building_nr, c.Geometry AS geometry, d.Classname FROM building a, THEMATIC_SURFACE b, SURFACE_GEOMETRY c, OBJECTCLASS d WHERE a.grid_id_400 = 4158 AND a.id = b.BUILDING_ID AND b.LOD2_MULTI_SURFACE_ID = c.ROOT_ID AND c.GEOMETRY IS NOT NULL AND b.OBJECTCLASS_ID = d.ID""")
obj = cursor.fetchone()
obj = obj[1]
print obj
cursor.callfunc("SDO2GEOJSON", cx.Oracle.OBJECT, [obj])
# Aufruf der App
if __name__ == "__main__":
app.run(web.profiler)
错误讯息: at / grid 全局名称'cx'未定义
但我确信cx_Oracle安装正确。此外,我在开头使用import cx_Oracle,这是有效的。
有什么问题?
答案 0 :(得分:1)
简单的拼写错误。在行
cursor.callfunc("SDO2GEOJSON", cx.Oracle.OBJECT, [obj])
您应该使用cx_Oracle.OBJECT
