SQL Query fails on SSRS 2005

I posted this question (http://www.experts-exchange.com/Microsoft/Development/MS-SQL-Server/SQL-Server-2005/Q_27655535.html) today regarding using a like in a join for SQL. The solution provided I was able to use - and get it to work in SQL 2005.

However, when I put it into SSRS 2005 I get errors and it isn't happy when ever I posted the code for the union.

The code (section) that works looks like:
left outer join [ServerName].HPD_HelpDesk HPD
on HPD.Summary like '%' + caption + '%'

Whenever I add this to my SSRS query it barfs.

The error looks like:
Could not generate a list of fields for the query.
Check the query syntax, or click Refresh Fields on the query toolbar.

Additional Information:
Implicit conversion from data type sql_variant to int is not allowed. Use the CONVERT function to run this query.

I wish I could but I can't. It came from another system and all I could do is scan it and put it as a pdf.

but that join does not make any sense? are you trying to use some columns from HPD.summary after adding that breaking code? also what is caption datatype? what is hpd.summary datatype?

when you do this, does it break?

on convert(varchar(max),HPD.Summary) like '%' + convert(varchar(max),caption) + '%'

HainKurt, I am trying to convert the PDF to text with an online OCR reader. I hope to post it in a few once I clean it up.

As for your last post the join is supposed to look in the 'summary' field in the HPD_HelpDesk table for any occurance of the value from the Caption field.

also looks like you need to add another condition here

left outer join [ServerName].HPD_HelpDesk HPD
on HPD.someCol=sometable.somecol and HPD.Summary like '%' + caption + '%'

without that condition, that code does not make any sense to me...

Not sure how to answer that. As I said it works ok in my SQL Studio when I uncomment the test values.

are you trying to do something like this?

with 
a as (select 1 id, 'a' caption),
b as (select 'a bb cc d' summary union select 'aa bbbb cccc')
select * from a left outer join b on b.summary like '%'+a.caption+'%'

id	caption	summary
1	a	a bb cc d
1	a	aa bbbb cccc

Open in new window

left outer join [ServerName].HPD_HelpDesk HPD
on charindex(caption, HPD.Summary)>0

Sorry, that last one really confused me.

Let me give you an example....

The main part of the query looks at the Events table and figures out all events that occured between the @StartDate and the @EndDate.

Sample:
Caption, EventTime, OutageInMinutes, Uptime, NumMinPeriod, CountOfAssets.....
------------------------------------------------------------------------------------------------------------
ABC1234, 0212-03-11 04:19:34, 168, 99.996, 43200, 71 ......
------------------------------------------------------------------------------------------------------------

I then want it to look at the HPD_HelpDesk Summary field to see if the Caption name shows up 'anywhere' in the Sumamry field (hence the like).

The Summary field might contain something like:
"The ABC1234 system is not working. Please open ticket...."

Nope, same thing. I soon as I paste it in and try to preview it craps out - same error.

I even deleted any commented out stuff (at top) to make sure it wasn't that.

HainKurt,

Doing some more testing I think the problem might be deeper than I thought and the new join might not be the problem.

While it works in SQL Studio and works in SSRS without the new code section when I go the Preview and deploy it I get an error when I try to just run the code in the Data mode.

I will have to research this further but will go ahead and give you the points as I think I can use the code idea you posted.

left outer join [ServerName].HPD_HelpDesk HPD
on charindex(caption, HPD.Summary)>0

does this make sense to you?

I converted the SP to use Table Variables instead of temp tables and it works now.

but still i do not get what column do you want from this hpd table

left outer join [ServerName].HPD_HelpDesk HPD
on charindex(caption, HPD.Summary)>0

will you add some columns into your select part from hpd table? if yes, try

left outer join (select summary from [ServerName].HPD_HelpDesk) HPD
on charindex(caption, HPD.Summary)>0

maybe there are some columns in this table which creates problems...
