Calling Oracle stored procedure from C#?

Question

How does one call a stored procedure in oracle from C#?

Answer 1

It's basically the same mechanism as for a non query command with:

• command.CommandText = the name of the stored procedure
• command.CommandType = CommandType.StoredProcedure
• As many calls to command.Parameters.Add as the number of parameters the sp requires
• command.ExecuteNonQuery

There are plenty of examples out there, the first one returned by Google is this one

There's also a little trap you might fall into, if your SP is a function, your return value parameter must be first in the parameters collection
