ExecuteNonQuery() returns -1 in Update when records are updated

Question

I\'ve verified that my method/Oracle procedure is working correctly, but in my C# I always get -1 returned from ExecuteNonQuery(). Consequently, the below bool is always fa

Answer 1

Try explicitly returning SQL%ROWCOUNT.

According to MSDN, DbCommand..ExecuteNonQuery will always return -1 for stored procedure calls:

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. For all other types of statements, the return value is -1.

If I remember correctly from my days of using lots of stored procs, I believe you would need to use an output argument to return stuff like the number of updated rows.

Answer 2

I'm not an Oracle guy, but apparently there's a command:

set feedback off

which prevents it from returning the count of records affected. Is this line in the stored procedure? Or have you tried 'set feedback on'? Functionally I think this is just the reverse of SQL Server's SET NOCOUNT ON/OFF command.
