Hello,

We are sometimes asked for examples of how to do 3rd party SQL database selects/updates/inserts/stored procedures from an Ensemble SQL Business Operation.

In the attached file there are 4 sample Ensemble Operations that demonstrate four different types of transactions with an external SQL DB:

AWS Glue is a fully managed ETL (extract, transform, and load) service that makes it simple and cost-effective to categorize your data, clean it, enrich it, and move it reliably between various data stores.

Overview

Encryption of sensitive data becomes more and more important for applications. For example patient names, SSN, address-data or credit card-numbers etc..

Cache supports different flavors of encryption. Block-level database encryption and data-element encryption. The block-level database encryption protects an entire database. The decryption/encryption is done when a block is written/read to or from the database and has very little impact on the performance.

With data-element encryption only certain data-fields are encrypted. Fields that contain sensitive data like patient data or credit-card numbers. Data-element encryption is also useful if a re-encryption is required periodically. With data-element encryption it is the responsibility of the application to encrypt/decrypt the data.

Both encryption methods leverage the managed key encryption infrastructure of Caché.

The following article describes a sample use-case where data-element encryption is used to encrypt person data.

But what if you have hundreds of thousands of records with an encrypted datafield and you have the need to search that field? Decryption of the field-values prior to the search is not an option. What about indices?

This article describes a possible solution and develops step-by-step a small example how you can use SQL and indices to search encrypted fields.

Where can i get the latest odbc providers from SQL Server 2012/2016?

I see some posts on line to an ftp site out there but I am unsuccessful at getting access to it. I have a version loaded on my server but get errors when querying cache'.

"[Cache ODBC][State : 22005][Native Code 22005]"

Any help would be appreciated.

the one we have might be version 2014.01.05851 64 bit (would that make sense?)

I have a code block in a BPL. I have the below SQL and code. All variables have been declared and set. When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct. If values are returned, I get a -400 error when I perform the first FETCH. I've investigated, but cannot find the reason for a -400 error. Hoping someone out here understands this and knows what's wrong.

If I have defined a class query in one of my classes and I want to use that query from a method of another class, what are the pros and cons of using the %SQL.Statement interface versus the %Library.ResultSet interface?

I believe %SQL.Statement is the newer interface.

So if the old way is:

USER>s rs=##class(%Library.ResultSet).%New("%Library.File:FileSet")
 
USER>s sc=rs.Execute("c:\s\","*.txt")
 
USER>w sc
1
USER>while rs.%Next() {w !,rs.Data("Name")}

...

then the new way is:

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?

Thanks in advance,

Best regards

Hey I would like to INSERT mulitple rows to 1 table. I need to intersystems cache equivelant for

INSERT INTO table_name (column_list)
VALUES
(value_list_1),
(value_list_2),
(value_list_3);

Have tried this post https://community.intersystems.com/post/how-execute-multiple-query-or-script-sql-management-studio
but still got an error

I'm running this code in our application, and in the terminal:

>set query="SELECT * FROM PMG_Data_Private.RemitInstance WHERE (VoucherNumber %INLIST ? SIZE ((10)))"

>set tRS = ##class(%ResultSet).%New("%DynamicQuery:SQL")

>set ok=tRS.Prepare(query)

>d $system.Status.DisplayError(ok)

ERROR #5540: SQLCODE: -76 Message: Cardinality mismatch between the SELECT-list and INTO-list
SQLTEXT: SELECT * FROM PMG_Data_Private.RemitInstance WHERE (VoucherNumber %INLIST ? SIZE ((10)))

Last week, we announced the InterSystems IRIS Data Platform, our new and comprehensive platform for all your data endeavours, whether transactional, analytics or both. We've included many of the features our customers know and loved from Caché and Ensemble, but in this article we'll shed a little more light on one of the new capabilities of the platform: SQL Sharding, a powerful new feature in our scalability story.

We have a routine in one namespace.

We have a Cache SQL table in a different namespace.

What is the syntax for inserting into this table from the routine in the other namespace?

Can this be done without using ZN?

Thanks.

Hi, Community,

This post will demonstrate how to display data on the web by using Embedded Python , Python Flask Web Framework and Jquery datatable

We will display processes from %SYS.ProcessQuery table.

I'm trying to get a count of specific message type with a specific entry and thought I could build the query in Message Viewer but this does not provide counts (as far as I am aware). So when I take the SQL from 'Show Query' it omits the segment criteria as the code shows below.

I have attached the criteria that has been excluded. Is this possible?

Thank you

The select query here "select Settings from Ens_Config.Item" in the SQL Query of management portal returns this:

ValidationHost 7ActOnTransformErrorHost1 ReplyCodeActionsHostE=D AlertOnErrorHost1 9 AlertGroupsHost$LabAlertGroup,1-CriticalAlertGroup BusinessPartnerHost

How do I isolate just one of the settings e.g. ReplyCodeActions or LocalInterface

For example, i want to search for all entries that have a value for ReplyCodeActions

I realize i can open the production in studio and search for those setting values.
