List comments for a work item

Returns all comments for a single work item. Filter by WorkItemId in the WHERE clause. Use this to show discussion history for one bug, task, or story. Columns include Id, Text, RenderedText, CreatedDate, CreatedBy, and ModifiedDate.

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 WorkItemComments 
WHERE WorkItemId=6455

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_AZURE_DEVOPS_IN_GATEWAY], 'SELECT * FROM WorkItemComments 
WHERE WorkItemId=6455')

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_AZURE_DEVOPS_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'SELECT * FROM WorkItemComments 
WHERE WorkItemId=6455'
EXEC (@MyQuery) AT [LS_TO_AZURE_DEVOPS_IN_GATEWAY]
