I have a text field (nvarchar max) that contains a chat transcript. I need to find the first chat entry that was not entered by one of our agents. That is, the first entry by the customer.
The transcript will look like this:
20:32:12 [Rachel] Thank you for contacting Our Company. How may I assist you?
20:32:31 [Marina Galofaro] What is the mailing address to mail a check?
20:32:49 [Rachel] I'm happy to provide you with the mailing address.
20:33:22 [Marina Galofaro] O kay, Thank you.
20:33:28 [Rachel] One moment please while I provide a link with directions to mail your payment.
20:34:05 [Rachel] Please click <a href="http://company.custhelp.com/app/answers/detail/a_id/1050/kw/payment" target="_blank">here</a> to view how to mail a payment.
20:35:07 [Rachel] Is there anything else I can help with, Marina?
20:35:56 [Marina Galofaro] No, Thank you!
20:36:00 [Marina Galofaro] Session Disconnected
So the first thing I need to do is find the name between the first set of brackets and compare the contents to another table that translates an ID on this table to a name.
If the name is found, then I need to move on to the next bracketed section and find that name and compare it. If it matches again, then move on to the next bracket, and so on. Once the name does not match, then I need to extract that first line of the chat, including the HTML tags. So basically back up 13 chars from that bracket and then grab the text through the next
tag.
I have something worked out for the first part to get that first bracketed name and compare it to the agent on the record.
SELECT A.ID
, A.Agent
, A.TextHTML
, charindex('[', TextHTML, 0) as FirstOpenBracket
, charindex(']', TextHTML, 0) as FirstClosedBracket
, SUBSTRING(TextHTML, CHARINDEX('[', TextHTML , 1) + 1, CASE WHEN (CHARINDEX(']', TextHTML , 0) - CHARINDEX('[', TextHTML, 0)) > 0 THEN CHARINDEX(']', TextHTML, 0) - CHARINDEX('[', TextHTML, 0) - 1 ELSE 0 END) as FirstBracketName
, U.FirstName as AgentFirstName
FROM Actions A INNER JOIN Users U on A.Agent = U.ID
WHERE A.[Type] = 9 AND A.CreationTime >= '2012-10-26 00:00:00' AND A.TimeAllocated > 0 AND A.TextHTML IS NOT NULL
But I don’t know where to go from there.
Can this even be accomplished “in line” ?
I don’t think so since the number of bracketed names until I hit the customer is dynamic.
Could anyone point me in the right direction?
Thanks
Paul

Perhaps this will help you find the path?

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.

What happens when the customer is called Rachel?

Great question. In most cases, the customer will be first and last name. But since this is not guaranteed, yes, there will be situations where the wrong line is picked up. We will just have to explain that this is not perfect. There really are no other options at this point.

Ok, I admit, I have no idea what this is doing.

I tweaked the code to what i thought would work (note that i added the WHERE ID = 6831908 just to limit to one row for testing)

But I get nothing back. Also, i do need to include the HTML tags before and after the first chat line from the customer.

WITH Transcript (message) AS (

SELECT TextHTML FROM Actions WHERE ID = 6831908),

Operators (FirstName) AS (

SELECT FirstName FROM Actions A INNER JOIN Users U on A.Agent = U.ID WHERE A.ID = 6831908)

SELECT message, FirstName

,operator=LEFT(operator, CHARINDEX(']', operator)-1)

,CHARINDEX(']', operator)

,TextOfMessage=LTRIM(RIGHT(operator, LEN(operator)-CHARINDEX(']', operator)))

FROM Transcript

CROSS APPLY (

SELECT SUBSTRING(message, CHARINDEX('[', message)+1, LEN(message))

) a(operator)

LEFT JOIN Operators ON LEFT(operator, CHARINDEX(']', operator)-1)=FirstName

WHERE FirstName IS NULL

This is mostly due to us being forced to speculate on your table. Dwain assume you have multiple rows but my guess is your table holds the entire discussion more in a format like this?

;WITH Transcript (message) AS (

SELECT '20:32:12 [Rachel] Thank you for contacting Our Company. How may I assist you?'

+ char(10) + char(13) + '20:32:31 [Marina Galofaro] What is the mailing address to mail a check?'

+ char(10) + char(13) + '20:32:49 [Rachel] I''m happy to provide you with the mailing address.'

+ char(10) + char(13) + '20:33:22 [Marina Galofaro] O kay, Thank you.'

+ char(10) + char(13) + '20:33:28 [Rachel] One moment please while I provide a link with directions to mail your payment.'

+ char(10) + char(13) + '20:34:05 [Rachel] Please click <a href="http://company.custhelp.com/app/answers/detail/a_id/1050/kw/payment" target="_blank">here</a> to view how to mail a payment.'

+ char(10) + char(13) + '20:35:07 [Rachel] Is there anything else I can help with, Marina? '

+ char(10) + char(13) + '20:35:56 [Marina Galofaro] No, Thank you!'

+ char(10) + char(13) + '20:36:00 [Marina Galofaro] Session Disconnected')

select * from transcript

Oh hell, i see the problem. I posted the raw data in my first post, but it acted on the HTML tags. I did not even notice that.

I cant seen to get it to post with the HTML tags.

Then you can combine that with Dwain's logic and voila!!!
