将Oracle数据库与Asp.net连接

Question

I use visual studio Express 2012 for Web and install ODTwithODAC1210 (oracle client), but the oracle client cannot integrate with visual studio. When I select Data source as "Oracle Database", there is only one Data provider ".Net Framework Data Provider for OLE DATA DB".

When I fillout all information, and test connection, I get following error:

Error while trying to retrieve text for error ORA-01019

Any one know how to solve this problem. I very need a hlep.

Answer 1

I too had this problem. I think this is mainly related to the procedure while installing oracle on your pc. And oracle sucks up big time connecting with visual studio.

I>

1) Download the 'Oracle developer tools for visual studio' link while creating a new server connection. (U can find this link on the right side where you are getting that ".Net Framework Data Provider for OLE DATA DB" option) 2) Uninstall oracle 3)now install oracle again and those tools u have downloaded.

II>

1) Or U can use Oracle XE plugin (google it, its around 160 MB) and carefully enter your username and passwords. 2) Now try to link it from VS.

Hope this help somewhat.

NOTE:- Still I dont recommend oracle with visual studio because even if you get a success in trying all above. But While writing a 'connection string' for DB in VS. Its again will give some kind of errors: such as word 'UNICODE' is not recognized, etc.
