cx-oracle

问题 There are so many related questions that I have gone through which made me wonder how come this is such a prevalent issue? Anyways, I am trying to use cx_Oracle module . I have the : instant client: instantclient-basic-win32-11.1.0.6.0.zip python - 3.4 cx_Oracle - cx_Oracle-5.2-11g.win32-py3.4.exe I have set up Path as well as the ORACLE_HOME variables.

As workaround, I used the solution

问题 So I followed these directions here to install Oracle InstantClient, installing Oracle Instantclient on Mac OS/X without setting environment variables?

问题 How can you get the number of affected rows from executing a "MERGE INTO..." sql command within CX_Oracle? When ever I execute the MERGE SQL on cx_oracle, I get a cursor.rowcount of -1. Is there a way to get the number of rows affected by the merge? 回答1: Since cx_oracle follows the python DBAPI specification (I presume), this is expected 'behaviour'. The exact same problem was discussed here on stackoverflow before. Some more links with possible solutions: http://www.oracle-developer.net
