Delete item from a named list

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.

DELETE FROM MyList WHERE Id=888
--OR--        
DELETE FROM MyList WITH (ListItemId='123')

--ListItemId can be retrieved by selecting from named list table, e.g. 'MyList'.

Using OPENQUERY in SQL Server

SELECT * FROM OPENQUERY([LS_TO_SHAREPOINT_ONLINE_IN_GATEWAY], 'DELETE FROM MyList WHERE Id=888
--OR--        
DELETE FROM MyList WITH (ListItemId=''123'')

--ListItemId can be retrieved by selecting from named list table, e.g. ''MyList''.')

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_SHAREPOINT_ONLINE_IN_GATEWAY] syntax.

DECLARE @MyQuery NVARCHAR(MAX) = 'DELETE FROM MyList WHERE Id=888
--OR--        
DELETE FROM MyList WITH (ListItemId=''123'')

--ListItemId can be retrieved by selecting from named list table, e.g. ''MyList''.'
EXEC (@MyQuery) AT [LS_TO_SHAREPOINT_ONLINE_IN_GATEWAY]
