tuple

The ListUsers function returns a list of named tuples. The named tuples returned each have the following five items: Name Datatype Description ClientName String Name of the client machine from where the connection is being made. ConnectionTime Datetime The time when the user made the initial connection to the geodatabase. ID Integer The SDE connection identifier. This is the value that can be used in the DisconnectUser function to identify the user to disconnect. IsDirectConnection Boolean True if the connection is a direct connection (two-tier). False if the connection is an application server connection (three-tier). Name String The name of the user who is connected to the database.

コードのサンプル

ListUsers example 1

import arcpy

arcpy.ListUsers("Database Connections/admin.sde")

ListUsers example 2

The following example demonstrates how to print a list of connected users along with their connection time.

import arcpy

users = arcpy.ListUsers("Database Connections/admin.sde")
for user in users:
    print("Username: {0}, Connected at: {1}".format(
        user.Name, user.ConnectionTime))

ListUsers example 3

The following example demonstrates how to generate a new list of only SDE IDs from the list returned by ListUsers.

import arcpy

# Set the admistrative workspace connection
arcpy.env.workspace = "Database Connections/[e-mail]"

# Create a list of users
'''
NOTE: When the arcpy.env.workspace environment is set, a workspace
does not need to be provided to the function.
'''
users = arcpy.ListUsers()

# Create a list of SDE ID's.
# Use a list comprehension to get the ID values in a new list.
id_users = [user.ID for user in users]
print(id_users)
