How to fetch presence in Lync 2013 from SQL server (using query)

Question

We are running Lync 2013 setup with 5 FE and 2 BE SQL (mirrored) servers.
How can i get presence information for our users by script or SQL queries?
My Concern is to fetch out current presence information of a list of users (CSV file) by script (Powershell or SQL query) for automation purpose. So that one need not to go to Lync 2013 (or anything) Client for every single user, to check their corresponding
presence.
E.g Say a service desk agent is handling tickets of 200 users per day. So it will be time consuming for him/her to go to Lync 2013 client and check presence for every user. It would be better for SD agent to operate, if we could make a script to fetch presence
status for the list of 200 users.
We will fetch the information when required and send a mail to him/her.
i have asked this question under Presence and IM forum.

Answer 1

Create a Store procedure which will give you integer value according to presence status:
USE [rtc]
GO
/****** Object:  StoredProcedure [dbo].[GetAvailability]    Script Date: 05/01/2015 10:36:35 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[GetAvailability]
@_Publisher varchar(50)
AS
DECLARE
@agrregate_state varchar(500),
@availability varchar(50),
@index_first int,
@index_last int,
@index int
BEGIN
SET NoCount ON
set @agrregate_state = (select top 1 Data from dbo.DiagPublisherDataView(@_Publisher) order by LastPubTime desc);
set @index_first = (select CHARINDEX('<availability>',@agrregate_state));
set @index_last = (select CHARINDEX('</availability>',@agrregate_state));
set @index = @index_first + 14;
set @availability = (SUBSTRING(@agrregate_state,@index,@index_last - @index));
return CONVERT(int, @availability);
END
GO
