I have a RAILS 3.0.10 application (using Ruby 1.9.2) that using the thinking_sphinx gem. Is it possible in the extended match mode to use the "or" operator
with the "near" operator so that thinking_sphinx will find text with
either word in group 1 within a specified proximity to either word in
group 2. For example, '(pro | support | apologist | backer | stalwart
| proponent | patron | partisan | hero | leader | martyr | aimed |
stop) NEAR/30 people' ? I am using sphinx 0.9.9-release.
ThinkingSphinx.search "pro support apologist", :match_mode => :any

I would like to use Presto API to get number of active workers, similar to the info available in PrestoUI.
I want to use the an API similar to (who don't contain this info):
https://presto/v1/status
https://presto/v1/jmx
AFAIK in latest Trino (formerly Presto SQL) versions the workers cannot be introspected from outside of the cluster, but you can get the listing with SQL:
presto> SELECT * FROM system.runtime.nodes;
node_id | http_uri | node_version | coordinator | state
---------------+------------------------+------------------+-------------+--------
presto-worker | http://172.20.0.3:8081 | 347-137-g4945abe | false | active
presto-master | http://172.20.0.4:8080 | 347-137-g4945abe | true | active
(2 rows)
I have a linked table to a Outlook Mailitem folder in my Access Database. This is handy in that it keeps itself constantly updated, but I can't add an extra field to relate these records to a parent table.
My workaround was to put an automatically generated/added ID String into the Subject so I could work from there. In order to make my form work the way I need it to, I'm trying to create a query that takes the fields I need from the linked table and adds a calculated field with the extracted ID so it can be referenced for relating records in the form.
The query works fine (I get all the records and their IDs extracted) but when I try to filter records from this query by the calculated field I get:
This expression is typed incorrectly, or it is too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables.
I tried separating the calculated field out into three fields so it's easier to read, hoping that would make it easier to evaluate for Access, but I still get the same error. My base query is currently:
SELECT InStr(Subject,"Support Project #CS")+19 AS StartID,
InStr(StartID,Subject," ") AS EndID,
Int(Mid(Subject,StartID,EndID-StartID)) AS ID,
ProjectEmails.Subject,
ProjectEmails.[From],
ProjectEmails.To,
ProjectEmails.Received,
ProjectEmails.Contents
FROM ProjectEmails
WHERE (((ProjectEmails.[Subject]) Like "*Support Project [#]CS*"));
I've tried to bind a subform to this query on qryProjectEmailWithID.ID = SupportProject.ID where the main form is bound to SupportProject, and I get the above error. I tried building a query that selects all records from that query where the ID = a given parameter and I still get the same error.
The working query that adds Support Project IDs would look like:
+----+--------------------------------------+----------------------+----------------------+------------+----------------------------------+
| ID | Subject | To | From | Received | Contents |
+----+--------------------------------------+----------------------+----------------------+------------+----------------------------------+

The view in question would populate a datasheet that looks the same with just the items whos ID matches the ID of the current SupportProject record, updating when a new record is selected. A separate text box should show the full content of whichever record is selected in that grid, like this:
Have you tried turning it off and on again?

Thanks for your question. The matter has been assigned to Support Project #CS2, and a support staff member will be in touch shortly to help you out. As it is considered of medium priority, you should expect daily updates.
Thanks,

I really need some help with my computer. It seems really slow and I can't do my work efficiently.
Neither of these things happens as when I try to use the calculated number to relate to the PK of the SupportProject table...
I don't know if this is a part of the problem, but whether I use Int(Mid(Subject... or Val(Mid(Subject... I still apparently get a Double, where the ID field (as an autoincrement ID) is a Long. I can't work out how to force it to return a Long, so I can't test whether that's the problem.
So that is output resulting from posted SQL? I really wanted raw data but close enough. If requirement is to extract number after ...CS, calculate in query and save query:
Val(Mid([Subject],InStr([Subject],"CS")+2))
Then build another query to join first query to table.
SELECT qryProjectEmailWithID.*, SupportProject.tst
FROM qryProjectEmailWithID
INNER JOIN SupportProject ON qryProjectEmailWithID.ID = SupportProject.ID;
Filter criteria can be applied to either ID field.
A subform can display the related child records synchronized with SupportProject records on main form.
I tested the ID calc with your data and then with a link to my Inbox. No issue with query join.
I want to represent a file-and-folder hierarchy in a Postgres 10 database. A structure like
Photos/
|-- Dog.jpg
|-- Cat.jpg
|-- Places/
|-- Paris.jpg
|-- Berlin.jpg
Songs/
|-- Happy.mp3
would be represented as something like
| id | filename | parent_id |
|----|------------|-----------|
| 1 | Photos | null |
| 2 | Songs | null |
| 3 | Cat.jpg | 1 |
| 4 | Happy.mp3 | 2 |
| 5 | Places | 1 |
| 6 | Berlin.jpg | 5 |
| 7 | Dog.jpg | 1 |
| 8 | Paris.jpg | 5 |
The database would track multiple users, and each user would have their own file-folder hierarchy.
I've been reading up on Postgres's ltree extension, and it seems like the solution to my problem, but I don't know if it is, and it's difficult to test. The labels seem like arbitrary strings -- is it possible to tell Postgres that a label should be an ID field in the same table? Would I need to create one initial root node for each user, only let them attach children to that or children of children of that, then issue a select * from nodes where path ># that rootnode, can you select descendants that way?
Or am I forcing Postgres to do something it was never intended to do, when I should be looking at other kinds of database?
To answer correctly: It depends on your use case.
If your trees are very static (sub nodes change not very often) then ltree is a really good choice. You can do very fast and comfortable queries for sub nodes and ordering. In that case I would do a single root reference for each user as you mentioned.
On the other hand: moving a sub tree in ltree could force you a huge rewrite of the ltree data structure. E.g. if you have a tree like 1.1.1, 1.1.2 and 1.2.1 and you want to change the order of the sub trees in first level after the root, all three values have to change their data.
So, if you tree structure is very dynamical I would try the structure you mentioned above: saving the parent node in an adjacency list (and maybe an index for ordering) and do the query with recursive CTE queries
https://www.postgresql.org/docs/current/static/queries-with.html
http://schinckel.net/2014/09/13/long-live-adjacency-lists/
Last but not least you could try it with the "nested sets" structure (https://en.wikipedia.org/wiki/Nested_set_model).
Every approach has its very own benefits and drawbacks. You have to do a very detailed analysis and maybe create some prototypes to test which one is the best for you.

I have a column called Description:
+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Description/Title |
+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Liszt, Hungarian Rhapsody #6 {'Pesther Carneval'}; 2 Episodes from Lenau's 'Faust'; 'Hunnenschlacht' Symphonic Poem. (NW German Phil./ Kulka) |
| Beethoven, Piano Sonatas 8, 23 & 26. (Justus Frantz) |
| Puccini, Verdi, Gounod, Bizet: Arias & Duets from Butterfly, Tosca, Boheme, Turandot, I Vespri, Faust, Carmen. (Fiamma Izzo d'Amico & Peter Dvorsky w.Berlin Radio Symph./Paternostro) |
| Puccini, Ponchielli, Bizet, Tchaikovsky, Donizetti, Verdi: Arias from Boheme, Manon Lescaut, Tosca, Gioconda, Carmen, Eugen Onegin, Favorita, Rigoletto, Luisa Miller, Ballo, Aida. (Peter Dvorsky, ten. w.Hungarian State Opera Orch./ Mihaly) |
| Thomas, Leslie: 'The Virgin Soldiers' (Hywel Bennett reads abridged version. Listening time app. 2 hrs. 45 mins. DOLBY) |

+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
Please note that above I'm only showing 1 field.
Also, the output that I would like is:
+-------+-------+
| Word | Count |
+-------+-------+
| Arias | 3 |
| Duets | 2 |
| Liszt | 10 |
| Tosca | 1 |
+-------+-------+
I want this output to encompass EVERY record. I do not want a separate one of these for each record, just one global one.
I am choosing to use SSIS to do this job. I'd like your input on which controls to use to help with this task:
I'm not looking for a solution, but simply some direction on how to get started with this. I understand this can be done many different ways, but I cannot seem to think of a way to do this most efficiently. Thank you for any guidance.
FYI:
This script does an excellent job of concatenating everything:
select description + ', ' as 'data()'
from [BroincInventory]
for xml path('')
But I need guidance on how to work with this result to create the required output. How can this be done with c# or with one of the SSIS components?
edit: As siyual points out below I need a script task. The script above obviously will not work since there's a limit to the size of a data point.
I think term extraction might be the component you are looking for. Check this out: http://www.mssqltips.com/sqlservertip/3194/simple-text-mining-with-the-ssis-term-extraction-component/
I need to know if there is a workaround on this error:
When I use Keywords like:
Location Should Be
Location Should Contain
(Which are both part of the Selenium2Library.)
I get this error:
"Location should have been 'http://www.google.pt' but was 'http://WwW.GooGLe.Pt'
I think that is because robot framework is natively case sensitive when comparing strings.
Any help?
Ty
EDIT
Question edited to clarify some subjects.
Luckily Robot Framework allows for keywords to be written in python.
MyLibrary.py
def Compare_Ignore_Case(s1, s2):
if s1.lower() != s2.lower():
return False
else:
return True
def Convert_to_Lowercase(s1):
return s1.lower()
MySuite.txt
| *Setting* | *Value* |
| Library | ./MyLibrary.py |
| *Test Case* | *Action* | *Argument*
#
| T100 | [Documentation] | Compare two strings ignoring case.
| | Compare Ignore Case | foo | FOO
#
| T101 | [Documentation] | Compare two strings where one is a variable.
# Should be Get Location in your case.
| | ${temp}= | MyKeyword that Returns a String
| | Compare Ignore Case | foo | ${temp}
I have not used the Selenium library, but the example in T101 should work for you.
Just in case someone else wants this:
Location should be '${expectedUrl}' disregard case
${currUrl} get location
${currUrl} evaluate "${currUrl}".lower()
${expectedUrl} evaluate "${expectedUrl}".lower()
should be equal ${currUrl} ${expectedurl}
Location should contain '${expected}' disregard case
${currUrl} get location
${currUrl} evaluate "${currUrl}".lower()
${expected} evaluate "${expected}".lower()
should contain ${currUrl} ${expected}
