I'm having trouble creating a view in cache with query like:

 

SELECT column1, column2, column 3
    FROM  table
    WHERE
        (column1, columnn 2) IN (SELECT c1, c2 FROM table2 GROUP BY c1)
    ORDER BY column1

 

I think the problem is in where clause, because it cannot take two columns .

 

the exact error: [SQLCODE: <-1>:<Invalid SQL statement>] [%msg: < ) expected, , found^ (column1,>]

 

Any idea on how to solve this?

 

Thank you.

I need to pass a parameter string that contains slashes to a REST call.

I tried URL encoding, or making URL map to accept query parameter instead of path parameter but apparently we only allow for path parameters.

I can come with several workarounds, but these involve some transformation at client and then on server, but I'd prefer a direct support.

Q1: is there any Cache specific trick to pass slashes in path parameters

Q2: are we going to support query parameters in REST?

something like this would help:

WebSockets look to be supported reasonably well in Cache. I have yet to use them in production so I am wondering how well it has worked for other developers.

In particular what happens when the browser does not support WebSockets, or when a firewall blocks the connection.

Have you had to write your own long polling fall-back?

I've read the documentation and found this interesting article...

Cache ODBC - Access Denied

Hello,

I'm working on integrating a Cache database into an existing .NET project of mine.  I'm trying to execute certain queries utilizing the Cache ODBC driver.  The first error I ran into was "[S1000] [Cache ODBC][State : S1000][Native Code 417] Access Denied".  The part that's throwing me for a loop though is that the application ran ~200 successful queries before I started getting that.  After some of those Access Denied errors, they turned into "[Cache ODBC][State : S1T00][Native Code 450] Request timed out due to user timeout".  This was all with the regular (2.5?) driver.

Hi all,

I have an incoming JSON message with a string field exceeding in length the 'caché long-string limit' of 3641144 characters.

Using {}.%FromJSON(instream) I am able to create %DynamicObject properly. However, I am unable to access the long property, as in every assignment, I get the <MAXSTRING> error.

Is there any way for me to obtain contents of the 'too long' string field as a stream?

Thanks

Jiri

I have been using the query below and it was working fine but now it's giving a SQL error. There were no changes made that could cause this to stop working. There is no Field 'APPLICATIONID' in the table.

QueueSQL=select distinct (convert(char(5),SkillsetID)+'='+Skillset) from iagentbySkillsetStat where ApplicationID > 10000
QueueMappingSQL=SELECT DISTINCT (convert(char(5),SkillsetID)+'='+Skillset), SkillsetID FROM iagentbySkillsetStat iagentbySkillsetStat WHERE (iagentbySkillsetStat.ApplicationID>10000)

Decoding Base64 PDF File

Hello, I am writing some cache code that will pick up a PDF file, Base64 encode the contents and then send on to a third party system within a Long String (via their API). I have been testing this and discovered that the PDFs do not open within the supplier system (I get an error saying that it hasn't been decoded correctly). I wanted to prove that the issue does not lie with the way that I have Base64 encoded it within Ensemble, and therefore as a test wanted to Encode the PDF stream, then decode the stream and write out to a new file.

Hi-

Im curious if there is any specific configuration that has to be done on an IIS web server to serve up RESTful web services.

I have a server that has IIS installed, with the CSP gateway.  a second server that has Cache installed on it.

I have configured a web application using the Cache System Management Portal for the web services that has a dispatch class pointing to my dispatch class.

I have created an application mapping in my CSP Gateway Management Portal on the web server such that url's with /webservices prefix are routed to my cache server.

I cannot connect to Cache from node.js  

I have installed in Windows 10 the following: CACHE 2016, node.js v 4.4.7 and  express .

-  where can I get cache.node? The link in the Intersystmes documentation  http://globalsdb.org/downloads/  doesn't work. I found cache0100.node and cache0120.node  in my Cache instance's  \bin directory. But I am not sure if I can use them or not.

 - how to install cache.node ? Where do I place it exactly? 

Can anyone recommend any tutorial or code example with installation instructions?

I setup a linked server to a cache database to query the data and when I try an query the data I get 

 

OLE DB provider 'MSDASQL' for linked server 'xxx' returned data that does not match expected data length for column '[MSDASQL].CSFAELIGVENCITY'. The (maximum) expected data length is 20, while the returned data length is 23.

 

Should I be using a different driver when setting up the DSN?

Greetings,

Is it possible to save Cache code into a file and then run it via command line?  

IE:  csession [ini] -U [ini] /path/cacheCodeFile.?

What I need to do is run a Cache script from the Linux command line.  The script will navigate data to produce a file and then it will exit back to the command line.

Thanks in advance for everyone's time.

Hi All -

I was wondering if the below query could be enhanced to automatically look back 24 hours from the current datetime the query is run. As is now I, of course, have to update the date range in the WHERE clause manually.

The query is just getting all MessageBodyClassNames, counting them and then doing an AVG on TimeCreated and TimeProcessed. Nothing too complex.

 

SELECT MessageBodyClassName, count(ID) as Count_Of_Messages, avg(datediff(ss, TimeCreated, TimeProcessed)) as avg_processing_time_in_seconds

FROM %PARALLEL Ens.MessageHeader

Hy.

 

I set up cache in container, which is working fine. But when accessing managment portal the default user was alway Unknown user and no username or password were required. So i disabled the Unknow user in the Security section, but now i keep getting an error access denid.

What is the correct way to write embedded SQL that will use a Like operator and local variable. Ex How can a sql query return the IDs of all rows where LastName has the substring "Doe"?

Set nameToFind="Doe". The below does not work.

&sql(Select ID from myTable where LastName like '%:nameToFind%')

Simple enough but this syntax is tricky!!

Cache for Raspberry Pi?

Some may think it's a strange / daft idea, but just today the Raspberry Pi folks have announced that they've now sold more than 10 million of them..and counting.  That's a huge potential marketplace, and a great platform for getting people to hear about Cache and try it out.  Given its focus on the education sector, another great way of getting heard about.

Hi,

I have a situation where I write a character stream to a file. The file content gets signed and the signature is sent to a service provider together with the file content.

The signing is done using openssl.

This works perfectly on a dev PC, which is runnning Windows and has a little-endian architecture.

The problem is as soon as I do this on the server, which has a big-endian architecture, the signed value is incorrect according to the service provider.

The content is signed using RSA SHA256 with PSS padding.

Authentication with REST

We are building a bunch of rest based services using Ens 2016.2 to serve our browser based application (Angular 4).

Two questions:

1. The initial authentication seems only work if credentials are placed in the url parameters.  Trying to use the Authorization header instead, the client code immediately complains about Access-Control-Allow-Origin. How can I resolve this?

 

2. After initial authentication, what is the proper way to send subsequent rest calls without having to include credential every time?
