Documentation

Create data source using ServiceNow ODBC Driver

Download and install ODBC PowerPack (if you haven't already).
Search for odbc and open the ODBC Data Sources (64-bit):
Create a User data source (User DSN) based on the ZappySys API Driver driver:

ZappySys API Driver
- Create and use a User DSN if the client application runs under a User Account. This is the ideal option at design time (e.g., when developing in Visual Studio). Use it for both types of applications (64-bit and 32-bit).
- Create and use a System DSN if the client application runs under a System Account (e.g., as a Windows Service). This is usually the required option in a production environment. If your Windows Service is a 32-bit application, you must use the 32-bit ODBC Data Source Administrator to configure this
When the Configuration window appears give your data source a name if you haven't done that already, then select "ServiceNow" from the list of Popular Connectors. If "ServiceNow" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:

ServicenowDSN

ServiceNow

Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.

Basic Auth (UserName and Password)

ServiceNow authentication

Authenticate using ServiceNow instance username and password.

Locate your ServiceNow instance credentials and use them for HTTP authentication:

Go to https://developer.servicenow.com/dev.do and log in.
Click on your profile picture.
When a menu appears, click on Manage instance password or a similar option:
In a new window you will see your HTTP Basic Authentication credentials:
Done! Use this username and password when configuring HTTP Authentication parameters.

Then go to Preview tab to start building a SQL query.
Once you do that, proceed by opening Query Builder:

ZappySys API Driver - ServiceNow

Read and write ServiceNow data effortlessly. Integrate, manage, and automate incidents, tasks, attachments, and records — almost no coding required.

ServicenowDSN
Then simply select the [Dynamic Table] table and Insert operation.
Continue by configuring the Required parameters. You can also set optional parameters too.
Move on by hitting Preview Data button to preview the results.

If you see the results you need, simply copy the generated query:

[Dynamic Table]

Insert

Required Parameters
TableName	Select the value from the dropdown
Optional Parameters
Allow Label as Input Value (Default: false - Use Id for reference field)
Advanced Properties
Date Time Value Handling

INSERT INTO incident(incident_state, severity, category, cause)
VALUES (3, 1, 'software', 'Missing a software feature.')

Click OK to use built SQL query and close the Query Builder.
Now hit Preview Data button to preview the data using the generated SQL query. If you are satisfied with the result, use this query in Alteryx:
ZappySys API Driver - ServiceNow

Read and write ServiceNow data effortlessly. Integrate, manage, and automate incidents, tasks, attachments, and records — almost no coding required.

ServicenowDSN
```
INSERT INTO incident(incident_state, severity, category, cause)
VALUES (3, 1, 'software', 'Missing a software feature.')
```
You can also access data quickly from the tables dropdown by selecting <Select table>.

A WHERE clause, LIMIT keyword will be performed on the client side, meaning that the whole result set will be retrieved from the ServiceNow API first, and only then the filtering will be applied to the data. If possible, it is recommended to use parameters in Query Builder to filter the data on the server side (in ServiceNow servers).

Let's not stop here and explore SQL query examples, including how to use them in Stored Procedures and Views (virtual tables) in the next steps.

ServiceNow SQL query examples

Use these SQL queries in your Alteryx data source:

Create an incident

Creates a new incident record.

INSERT INTO incident(incident_state, severity, category, cause)
VALUES (3, 1, 'software', 'Missing a software feature.')

Create an incident using display values

This example demonstrates how to create a new incident record by supplying human-readable labels (display values) for reference fields instead of their underlying sys_id values.

Normally, ServiceNow requires reference fields (such as caller_id or assignment_group) to be populated using the target record's sys_id. In this example, label-to-ID resolution is explicitly enabled using AllowDisplayValueAsInput='true', allowing display values to be passed instead.

This approach is useful for ad-hoc operations, demos, or interactive usage. For automated or high-volume integrations, using sys_id values is strongly recommended.

-- Create a new Incident using DISPLAY VALUES (labels) for reference fields
-- Instead of passing sys_id values, this example uses human-readable labels.
-- This works ONLY because AllowDisplayValueAsInput='true' is specified.

INSERT INTO incident
(
	short_description,
	incident_state,
	severity,
	category,
	caller_id,           -- reference to sys_user
	assignment_group     -- reference to sys_user_group
)
VALUES
(
	'Email service is intermittently failing',
	2,                   -- In Progress
	1,                   -- High severity
	'software',
	'John Doe',          -- LABEL (user display name), not sys_id
	'Network'            -- LABEL (group name), not sys_id
)
WITH(AllowDisplayValueAsInput='true')

insert_table_row endpoint belongs to [Dynamic Table] table(s), and can therefore be used via those table(s).

Create SQL view in ODBC data source

ZappySys API Drivers support flexible Query language so you can override Default Properties you configured on Data Source such as URL, Body. This way you don't have to create multiple Data Sources if you like to read data from multiple EndPoints. However not every application support supplying custom SQL to driver so you can only select Table from list returned from driver.

If you're dealing with Microsoft Access and need to import data from an SQL query, it's important to note that Access doesn't allow direct import of SQL queries. Instead, you can create custom objects (Virtual Tables) to handle the import process.

Many applications like MS Access, Informatica Designer wont give you option to specify custom SQL when you import Objects. In such case Virtual Table is very useful. You can create many Virtual Tables on the same Data Source (e.g. If you have 50 URLs with slight variations you can create virtual tables with just URL as Parameter setting.

Go to Custom Objects Tab and Click on Add button and Select Add Table:
Enter the desired Table name and click on OK:
And it will open the New Query Window Click on Cancel to close that window and go to Custom Objects Tab.
Select the created table, Select Text Type AS SQL and write the your desired SQL Query and Save it and it will create the custom table in the ZappySys Driver:
Here is an example SQL query for ZappySys Driver. You can insert Placeholders also. Read more about placeholders here
```
SELECT
  "ShipCountry",
  "OrderID",
  "CustomerID",
  "EmployeeID",
  "OrderDate",
  "RequiredDate",
  "ShippedDate",
  "ShipVia",
  "Freight",
  "ShipName",
  "ShipAddress",
  "ShipCity",
  "ShipRegion",
  "ShipPostalCode"
FROM "Orders"
Where "ShipCountry"='USA'
```
That's it now go to Preview Tab and Execute your custom virtual table query. In this example it will extract the orders for the USA Shipping Country only:
```
SELECT * FROM "vt__usa_orders_only"
```

Delete a table row in Alteryx via SQL view

Open Alteryx Designer.
First, verify your DCM Settings to ensure you can access ODBC drivers. Go to Options > User Settings > Edit User Settings.

If DCM Mode is set to DCM Only, change it to DCM Optional if you would like to access the legacy Generic ODBC Connection.

After changing this setting, you may need to click Save and restart the connection window for the "Generic ODBC" icon to appear.
Drag an Input Data tool onto your Alteryx canvas.
In the Configuration pane, click Set Up a Connection.
Note for DCM Users: If your environment has DCM (Data Connection Manager) enabled, the classic "Generic ODBC" icon may be hidden. To find it, select Data sources on the left and type "ODBC" in the search bar.
Once the ODBC window opens, click Connect Asset and select your ServicenowDSN DSN from the list.

Ensure you have configured a 64-bit System DSN in the Windows ODBC Data Source Administrator before this step.
After selecting your DSN, configure your SQL Query in the Input Data tool configuration:
To save your data, drag an Output Data tool and connect it to the Input Data tool.
Configure the Output Data tool to write to a CSV file:
Press Run (Ctrl+R) to execute the workflow. Verify the results in the Results Window at the bottom.

Creating SQL stored procedures

You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.

Steps to create Custom Stored Procedure in ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

Go to Custom Objects Tab and Click on Add button and Select Add Procedure:
Enter the desired Procedure name and click on OK:
Select the created Stored Procedure and write the your desired stored procedure and Save it and it will create the custom stored procedure in the ZappySys Driver. Here is an example stored procedure for ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here
```
CREATE PROCEDURE [usp_get_orders]
    @fromdate = '<<yyyy-MM-dd,FUN_TODAY>>'
 AS
    SELECT * FROM Orders where OrderDate >= '<@fromdate>';
```
That's it now go to Preview Tab and Execute your Stored Procedure using Exec Command. In this example it will extract the orders from the date 1996-01-01:
```
Exec usp_get_orders '1996-01-01';
```
