Passing an array from .Net application to Oracle stored procedure

Question

I need to pass an array from C#.net application to oracle stored procedure. Can anyone please let me know how to go about it? Also, which OracleType type do I use in C# when passing input parameter to stored procedure?

FYI, am using System.Data.OracleClient in my C# app.

Thanks.

Answer 1

Jimmy, the System.Data.OracleClient does not support arrays.

Depending on your need, you will either need to implement this via nested table types (via UDTs or assoc. arrays) using the ODP.net clients. This is probably a good direction to go, esp. since .net 4.0 has deprecated System.Data.OracleClient.

But if you are stuck with the System.Data.OracleClient and you are really just trying to do a variable in-list, you can do this by passing in a string and following some of these suggestions: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:210612357425

hope this helps

You should use DB-defined nested table types to pass an array to PL/SQL. Take a look at this nice tutorial, it might help you.
