How do you get output parameters from a stored procedure in Python?

Question

I\'ve googled around a bit, but maybe I didn\'t put the correct magik incantation into the search box.

Does anyone know how to get output parameters from a stored p

Answer 1

I was able to get an output value from a SQL stored procedure using Python. I could not find good help getting the output values in Python. I figured out the Python syntax myself, so I suspect this is worth posting here:

import sys, string, os, shutil, arcgisscripting
from win32com.client import Dispatch
from adoconstants import *

#skip ahead to the important stuff

conn = Dispatch('ADODB.Connection')
conn.ConnectionString = "Provider=sqloledb.1; Data Source=NT38; Integrated Security = SSPI;database=UtilityTicket"
conn.Open()

#Target Procedure Example: EXEC TicketNumExists @ticketNum = 8386998, @exists output

Cmd = Dispatch('ADODB.Command')
Cmd.ActiveConnection = conn

Cmd.CommandType = adCmdStoredProc
Cmd.CommandText = "TicketNumExists"

Param1 = Cmd.CreateParameter('@ticketNum', adInteger, adParamInput)
Param1.Value = str(TicketNumber)
Param2 = Cmd.CreateParameter('@exists', adInteger, adParamOutput)

Cmd.Parameters.Append(Param1)
Cmd.Parameters.Append(Param2)

Cmd.Execute()

Answer = Cmd.Parameters('@exists').Value
