Read changes
Reads all change requests from the system. This is essential for change management and tracking modifications to the IT environment.
The Changes table provides a list of all change records, including their type, impact, and status.
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 Changes
Using OPENQUERY in SQL Server
SELECT * FROM OPENQUERY([LS_TO_MANAGEENGINE_SERVICEDESK_PLUS_ZOHO_IN_GATEWAY], 'SELECT * FROM Changes')
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 Changes'
EXEC (@MyQuery) AT [LS_TO_MANAGEENGINE_SERVICEDESK_PLUS_ZOHO_IN_GATEWAY]
