I have a class that has a property calledTags (like DescriptiveWords, but tags), where multiple tags are possible. I am trying to decide on list of Objects vs. array of Objects.
I want to switch between different DSNs in business operations to query different servers, but the DO ..Adapter.DSNSet("DSNName") code will report a 15-second connection timeout error when switching DSNs. What should I do?
I have a function that may end up being called from a number of transformations at the same time, and within the function there's some Embedded SQL to first check if a local table has an entry, and then adds the entry if it doesn't exist.
To prevent a race condition where the function is called by two transformations and they both end up attempting to insert the same value, I'm looking to use the table hint "WITH TABLOCK" on the insert, but this seems to be failing the syntax checks within vscode.
Running TuneTable accounts among other the parameter named Block Count. In documentation, we see that this is an approximate numbers of 2K-blocks in which SQL-maps are stored. Databases in recent Cache doesn't support 2K-physical blocks so SQL-blocks are not physical blocks as it seems. So two questions:
- what are these blocks?
- how knowledge about count of blocks can help in SQL optimization?
How to simply going to get the value of the system language from ^%z? Because I got a problem, U2 context isn't setup while connecting the SQL Connect.
I am trying to replace one of our SQL Integration Service jobs with Ensemble and I am running into an issue executing a query against a MS SQL database using JDBC drivers.
I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?
I am trying to populate a table using the sql Data Import Wizard. The input file is a tab delimited text file. But the import keeps failing with a 104 error showing validation for the columns which use %Library.TimeStamp and %Boolean datatypes is failing. Yet when I insert values into the table through a SQL insert command, the values get saved correctly in the table.
For the TimeStamp format in the wizard form, I am choosing YYYY-MM-DD-HH:MI:SS because there was no option for this format: YYYY-MM-DD HH:MM:SS.
Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:
Converting between internal and ODBC formats.
Converting between local time, UTC, and Posix time.
Converting to and from various date display formats.
the ODBC driver is truncating the string to 50 characters.
If I run this same command with $system.SQL.Shell(), this doesn't occur. I did a test creating several parameters for COSClass_Methode, and they all have a 50 character limitation.
Our team is reworking an application to use REST services that use the same database as our current ZEN application. One of the new REST endpoints uses a query that ran very slowly when first implemented. After some analysis, we found that an index on one of the fields in the table greatly improved performance (a query that took 35 seconds was now taking a fraction of a second).
Problem to Solve: When an HL7 message hits a particular Process, I need to use the placer order number therein to query the messages that came in over the last 24 hours on a particular Service and grab discrete pieces of data that came in the latest message that has that placer order number.
In our application made in Caché object script, when we deploy some classes modified we have the option of calling "Purge queries" feature of Caché.
We only were doing this call when a %Persistent class definition (table) was modified, as we assume that no other changes affect the cached queries and we don't want to purge them by default, as the first run of a query becomes slow.
We had a case where no table definition was changed but a purge queries was the solution.
On the Latest GlobalSummit 2022, InterSystems Introduced Cloud SQL. So, you may have lightweight InterSystems IRIS with access to SQL only. Well, what if you would still need some Interoperability features in the cloud as well? There are various solutions on the market nowadays, which offer a bunch of integration adapters out of the box and can be extended with support from the community. Some time ago, I've implemented an adapter for the Node-RED project, which can be deployed manually everywhere you want. Now I would like to introduce a new integration with my recent discovery, n8n.io
n8n.io is a workflow automation platform, that supports over 200 different integrations out of the box and from a community, and now including InterSystems IRIS.
Let’s imagine that you are a Python developer or have a well-trained team specialized in Python, but the deadline you got to analyze some data in IRIS is tight. Of course, InterSystems offers many tools for all kinds of analyses and treatments. However, in the given scenario, it is better to get the job done using the good old Pandas and leave the IRIS for another time.
Has anyone use any other setting then -1 on the Stay Connected setting on a SQL.OutboundAdapter? I am having issues with a particular database and wonder if it would be beneficial since I only connect once a day to read the data from the Adapter to create an HL7 message.
I am currently adding a field to our Existing messaging from Epic, however there might be a possibility I need to back load data into the Ancillary system. While I have the previous messages that can be sent, they do not have this additional field that I am adding to the message.
I can do a lookup against Epic Clarity SQL Database; however, I don't want to throw a wrench into the workflow if the system cannot connect to the Epic Clarity SQL Database.
The basic idea is to use Vectors in the mathematical sense. I used geographic coordinates. These are of course only 2-dimensional but much easier to follow as vectors in text analysis with >200 dimensions.
So, you checked your server and saw that IRISTEMP is growing too much. There's no need to panic. Let’s investigate the issue before your storage runs out.
Step 1: Confirm the IRISTEMP Growth Issue
Before assuming IRISTEMP is the problem, let’s check its actual size.
Whenever I try to run a simple query on a production database table, I get a timeout 504 error. I'm using the SQL interface in Ensemble. One of the queries is a simple SELECT TOP 10. Even SELECT COUNT(*) gives a timeout.
I have tried to run the SQL Runtime Statistics, but this gives me a timeout as well.
Does anyone have an idea where I might look to find what is causing this?
