Comma Separated Tags from BLT?

Was reading the help documentation and noticed that there is a way to pass in comma separated tags to a query template:
TagName
One or more tag names to be queried
String Or String List
None
The name of a tag in the underlying data source. This parameter can be repeated multiple times in a URL if multiple tags are to be queried, and multiple tags can be passed in a single parameter as a comma-separated list of tag names.
I tried this from a BLT and it didn't work. What is the trick to get this to work? I have about 50 tags to query and I dont want to hard code the mappings and I would rather not fire 50 individual queries.
Any thoughts?

Brian,
You can't do it from an APPLET perspective or a standard TagQuery action block in BLS because of the explicit TagName.1 to TagName.128 query properties. The TagName property you found in the help only works for a direct query to the Illuminator servlet such as: http://<server:port>/Lighthammer/Illuminator?Server=Simulator&Mode=Current&TagName=L1Speed,L1Yield,AssetUtil1
If you need to wrap this functionality inside BLS or simply want to use it in an applet, then drop something like this into an XMLQuery template:
http://localhost/Lighthammer/Illuminator?QueryTemplate=Path/File&StartDate=[SD]&EndDate=[ED]&TagName=[Param.1]&Content-Type=text/xml
Assumptions would then be that you can bundle your data server and mode information in the query template (or you can keep them explicit with Server and Mode like in the first example and [Param.x] the right side of the equal sign to allow for simple Current/History/HistoryEvent changes). The [SD] and [ED] tokens will make the XMLQuery known to be time sensitive to an iChart so the default 60 minutes, etc. will go into the http request and give you the convenient VCR controls in the time control bar.

The code above has unblanaced parentheses. If you are getting anything other than an error message, then I don't believe you are really running what you posted.
Whenever you have a problem, post a complete test script that people can use to recreate the problem and test their ideas.
Please do that. Post CREATE TABLE and INSERT statements to crate the sample data, the code you used to create the carachr2_ntt type and the function, and your best attempt at a query (formatted). Simplify as much as possible. For example, do you really need 3 tables to illustrate the problem? For purposes of asking a question on this forum, can't you pretend you have just one table, with 2 columns?
I suspect the problem has to do with the user-defined type and function, which you didn't post. I can't even see how you called the function in your query. Without the information I mentioned above, there's not much I can do to help you.

Changing to comma separated values from a table

Hi Gurus
I have a column called ID and second column duplicatesID. So for each ID I can have more than one Duplicate ID.
I want to have comma separated for values of Dup IDs for each ID.
so
ID | DuplicateIDs
1 | 10501
1 | 2010
2 | 103
2 | 109856
2 | 1245
result wanted is
ID | DupsIDs
1 | 10501 , 2010
2 | 103,109856, 1245
regards,
ebro

My preferred way is this
SELECT ID,
STUFF((SELECT ',' + CAST( DuplicateIDs AS varchar(10)) FROM table WHERE ID = t.ID FOR XML PATH(''),TYPE).value('.','varchar(max)'),1,1,'') AS DupsIDs
FROM (SELECT DISTINCT ID FROM Table)t

Comma Separated Value Taking too Much Time to Execute

Hi,
select ES_DIAGNOSIS_CODE DC from ecg_study WHERE PS_PROTOCOL_ID LIKE 'H6L-MC-LFAN'
The above query returns comma separated value from the above query.
I am using the query below to split the comma separated value but the below query is taking lot of time to return the data.
SELECT
select DC from (
with t as ( select ES_DIAGNOSIS_CODE DC from ecg_study WHERE PS_PROTOCOL_ID LIKE 'H6L-MC-LFAN' )
select REGEXP_SUBSTR (DC, '[^,]+', 1, level) DC from t
connect by level <= length(regexp_replace(DC,'[^,]*'))+1 )
Please suggest me is there any alternative way to do this comma separated value.
Thanks

Hi BluShadow,
I know that this function is fast with varchar2 strings from several years of using it. With CLOBs one may need something faster, but the OP didn't menion CLOBs.
Best regards,
NikolayJust because you perceive it to be fast doesn't mean it's faster than doing it in SQL alone.
For starters you are context switching from the SQL engine to PL/SQL to call it.
Then in your code you are doing this...
select substr(v_str,v_last_break+1, decode(v_nxt_break,0,v_length, v_nxt_break-v_last_break-1)) into v_result from dual;which is context switching back from the PL/SQL engine to the SQL engine for each entry in the string.
Why people do that I don't know... when PL/SQL alone could do it without a context switch e.g.
v_result := substr(v_str,v_last_break+1, case when v_nxt_break = 0 then v_length else v_nxt_break-v_last_break-1 end);So, if you still think it's faster than pure SQL (which is what the OP is using), please go ahead and prove it to us.

Using Comma-Separated Selector

I am building a site with products that can have different colors.
Some products share colors.
I am using the Comma-Separated Selector to select the available colors for each product from a list.
My problem is showing each product and the colors available for each product.
How do I create a recordset that pulls only the colors I need from the colors table based on the comma separated feild from the products table?
Thanks for any help or point in the right direction.

Difficult to say without seeing how your database is planned
Nested region? - probably not
take a look at the MYSQL query with uses
HAVING IN (items in a comma separated list, item, item, etc)
this is the same approach as the article you mentioned
also a similar problem (possibly) mentioned here...

Exporting Metadata (caption information) from JPEGS to a comma separated value (CSV) file

Here is my dilemma. I am an archivist at an arts organization and we are in the process of digitizing many of our materials to post them on the web and make them available to internet users. One of the principle components of our collection is a large trove of photographs. We have been in the process of digitizing these images and embedding metadata (in the Caption/Description, Author/Photographer and Copyright fields) via PhotoShops File Info command.
Now I am at a crossroads. We need to extract this metadata and transfer it into a comma separated value form, like an Excel spreadsheet or a FileMakerPro database. I have been told that it is not possible to do this through PhotoShop, that I must run a script through Acrobat or Bridge. I have no clue how to do this. I have been directed to a couple of links.
First I was directed to this (now dead) link: http://www.barredrocksoftware.com/products.html
The BSExportMetadata script allegedly exports the metadata from files selected in Adobe's Bridge into a comma separated value (CSV) file suitable for import into Excel, Access and most database programs. It installs as a Bridge menu item making it simple to use. The the Export Metadata script provides you with an easy to use wizard allowing you to select associated information about a set of images that you can then export. This script requires Creative Suite 2 (CS2). This script sounds like it does exactly what I want to do, but unfortunately, it no longer exists.
Then I found this:
Arnold Dubin, "Script to Export and Import Keywords and Metadata" #13, 8 Aug 2005 7:23 am
I tried this procedure, but nothing seemed to happen. I also tried to copy the script into the JAVASCRIPT action option in Acrobat, but I received a message that the script had an error. It also seems to me that this script does not set up a dumping point, that is, a file into which this information will be exported to.
I am a novice, not a code writer or a programmer/developer. I need a step-by-step explanation of how to implement this filtering of information. We have about 2000 jpeg and tiff files, so I would rather not go through each file and copy and paste this information elsewhere. I need to find out how to create a batch process that will do this procedure for me. Can anyone help?

Hello -
Is anyone aware of a tool that will do the above that is available for mac? Everything I've found so far seems to be PC only.
Any help is appreciated, thanks!

SSRS Report : Comma Separated Hyperlinks

Hello,
I want to display Comma Separated Hyperlinks in SSRS Report. I am not sure what should I change here to get this working.
Below is the flow of data.
1. Extracting value from the SharePoint List using SSIS Package Script component and filling data in SQL Table.
I have used this Table and created below view to stuff all these three links together.
SELECT ID, STUFF
((SELECT ', ' + BCM.BCMProgramDocument
FROM BCMProgramDocumentation BCM
WHERE BCM.Risk = R.ID FOR XML PATH('')), 1, 1, '') AS BCMDoc
FROM Risk R
which gives me below output, not sure why.
"<a href='http://yahoo.com'>YAHOO</a>", "<a href='http://gmail.com'>GMAIL</a>", "<a href='http://hotmail.com'>HOTMAIL</a>"
Then in the SSRS Reporting, I have placed a PlaceHolder with HTML View selected and gave above field value in the expression.
They are not appearing as comma separated Hyperlinks.
Can anyone please help me on this ? What are the changes required in above steps ?
Thank you,
Mittal.

Hi Mittal,
According to your description, you want to show three links together with comma separated from BCMProgramDocument column to a report table. After testing the issue in my environment, we can refer to the following steps to achieve your requirement:
Use the following query create a dataset:
select * from BCMProgramDocumentation
Click Fields in the left pane, add a Calculated Field as below:
Field Name: ID2 Field Source: 1
Drag a table to design surface, then insert the expression below in the detail row:
=JOIN(lookupset(Fields!ID2.Value,Fields!ID2.Value,Fields!BCMProgramDocument.Value,"DataSet1"),",")
Right-click the Placeholder to open Placeholder Properties, then select ‘HTML-Interpret HTML tags as styles’ as Markup type.
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.
Thanks,

How to remove html tags from a column

Hi
Problem is this: I get a column with a comma separated list of id's and I can successfully parse these id's and use them elsewhere. BUT, occasionally there are html tags within that id list like this:
1082471,1237423<br xmlns="http://www.w3.org/1999/xhtml" />
Is there a way to just automatically remove all tags from a column? Could do this with regex, but since there is no support, I don't know what to do.

Hi,
If the HTML can be detected by a starting symbol like „<“, then you could use the following:
Unfortuntely the operation “ReplaceRange” is only available on a Text-level, so you have to invoke a function (at least to my knowledge). You also need an Index-column in your table, so if you don’t have it, you need to create one as well.
This is your function:
let
   fnRemoveHTML = (Value, Index) =>
let
   Source = Excel.CurrentWorkbook(){[Name="Tabelle1"]}[Content],
   IndeNo = Index,
   Value_ = Source{IndeNo-1}[Value],
   length = Text.Length(Text.From(Value_)),
   position = Text.PositionOf(Text.From(Value_), "<"),
   range = length-position,
   new= if Value_ is number then Value_ else Text.ReplaceRange(Value_, position, range, "")
in
    new
in
fnRemoveHTML
And this is how you invoke it:
let
    Quelle = Excel.CurrentWorkbook(){[Name="Tabelle1"]}[Content],
    Last = Table.AddColumn(Quelle, "Custom", each fn_RemoveHTML([Value], [Index])),
    ChangedType = Table.TransformColumnTypes(Last,{{"Custom", type number}})
in
    ChangedType
Provided your table is called “Tabelle1” & the column with your values to be replaced “Value” & your index-col “Index”

MODEL clause to process a comma separated string

Hi,
I'm trying to parse a comma separated string using SQL so that it will return the parsed values as rows;
eg. 'ABC,DEF GHI,JKL' would return 3 rows;
'ABC'
'DEF GHI'
'JKL'
I'm thinking that I could possibily use the MODEL clause combined with REGULAR expressions to solve this as I've already got a bit of SQL which does the opposite ie. turning the rows into 1 comma separated string;
select id, substr( concat_string, 2 ) as string
from (select 1 id, 'ABC' string from dual union all select 1, 'DEF GHI' from dual union all select 1, 'JKL' from dual)
model
return updated rows
partition by ( id )
dimension by ( row_number() over (partition by id order by string) as position )
measures ( cast(string as varchar2(4000) ) as concat_string )
rules
upsert
iterate( 1000 )
until ( presentv(concat_string[iteration_number+2],1,0) = 0 )
( concat_string[0] = concat_string[0] || ',' || concat_string[iteration_number+1] )
order by id;
Can anyone give me some pointers how to parse the comma separated string using regexp and create as many rows as needed using the MODEL clause?

Yes, you could do it without using ITERATE, but FOR ... INCREMENT is pretty much same loop. Couple of improvements:
a) there is no need for CHAINE measure
b) there is no need for CASE in RULES clause
c) NVL can be applies on measures level

Like

Can you send the query Plz!

These all will do the same
