Read purchase orders

Reads all purchase orders from the system. This allows you to track procurement activities and order statuses.

The PurchaseOrders table lists all orders, providing a view into the purchasing history and pending requests.

Standard SQL query example

This is the base query accepted by the connector. To execute it in SQL Server, you have to pass it to the Data Gateway via a Linked Server. See how to accomplish this using the examples below.

SELECT * FROM PurchaseOrders

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_MANAGEENGINE_SERVICEDESK_PLUS_ZOHO_IN_GATEWAY], 'SELECT * FROM PurchaseOrders')

Using EXEC in SQL Server (handling larger SQL text)

The major drawback of OPENQUERY is its inability to incorporate variables within SQL statements. This often leads to the use of cumbersome dynamic SQL (with numerous ticks and escape characters).

Fortunately, starting with SQL 2005 and onwards, you can utilize the EXEC (your_sql) AT [LS_TO_MANAGEENGINE_SERVICEDESK_PLUS_ZOHO_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT * FROM PurchaseOrders'
EXEC (@MyQuery) AT [LS_TO_MANAGEENGINE_SERVICEDESK_PLUS_ZOHO_IN_GATEWAY]
