SQL is a standard language for storing, manipulating and retrieving data in relational databases.

I HAVE A NEW SQL CLASS THAT DISPLAYS ENTRIES BASED ON THE FIRST 2 NODES OF A GLOBAL. I FOUND OUT THAT THE CLASS ALLOWS FOR AN ADDITIONAL NODE(s) TO BE INSERTED IN THE "User Specification Node:" along the delimiter and the Piece in the NewStorage Map1 for "ModifyDDDD" shown below. it is not working.

By default, the order of columns in a table is determined automatically by the system. To change the order, explicitly set the order for each property using the property keyword SqlColumnNumber when defining the class.

Example:

Property Name As %String [SqlColumnNumber = 2];

Please see the documentation below.

Hence the question: is there a way to do that?

The goal is to get data (from half a thousand to 3-4 thousands lines) from DB, calculate standart deviation then use it as logical condition in analyzer.

For example IF std > custom_value = show_the_result ELSE null

There is a STDDEV(MDX) method used in Analyzer but it is a measure and it can not be used as logical condition (correct me if i am wrong)

The rise of Big Data projects, real-time self-service analytics, online query services, and social networks, among others, have enabled scenarios for massive and high-performance data queries. In response to this challenge, MPP (massively parallel processing database) technology was created, and it quickly established itself. Among the open-source MPP options, Presto (https://prestodb.io/) is the best-known option. It originated in Facebook and was utilized for data analytics, but later became open-sourced.

I'm playing with some anayltic queries against FHIR server tables. The HSFHIR_X0002_S_Patient.addressCity table contains a lot of cities which names contain german charachers such as ä, ö and ü.

The following query works fine:

select value from HSFHIR_X0002_S_Patient.addressCity

But this one converts city names to uppercase, and characters with umlauts are lost, so instead of "Köln" or "München" I see KOLN and MUNCHEN:

I am using a JDBC connection to MS SQL server to execute a stored procedure to select data and bring it into InterSystems as a EnsLib.SQL.Snapshot. I loop through the EnsLib.SQL.Snapshot using a while loop, but I also want to iterate through the Columns within that Row to do logic.

Is there a way to iterate through the Columns of the current Row of the EnsLib.SQL.Snapshot so I can apply logic/rules for further processing?

Thanks

Scott

In the world of APIs, REST is very extended. But what happens when you need more flexibility in your data-fetching strategies? For instance letting the client to choose what fields is going to receive. Enter GraphQL, a query language for your APIs that provides a flexible alternative to REST.

In this post, we will:

  • Compare REST and GraphQL.
  • Dive into the basics of GraphQL: Queries, Mutations, and HTTP.
  • Build a simple GraphQL server implementation using Graphene, SQLAlchemy, and Flask over data in InterSystems IRIS.
  • Explore how to deploy your GraphQL server as a WSGI application in IRIS.

Hello Friends,

I have a question how to order by %DLIST, this is my code:

SELECT

$ListToString(%DLIST(DISTINCT MRDIA_ICDCode_DR->MRCID_Code),', ' ) ICDX,

$ListToString(%DLIST(DISTINCT (MRDIA_ICDCode_DR->MRCID_Desc || ' (' || MRDIA_DiagnosisType_DR->DTYP_Code || ')')),', ' ) Diagnose

FROM SQLUser.PA_Adm

LEFT JOIN SQLUser.PA_AdmInsurance ON (PAADM_RowID = INS_ParRef AND INS_Rank = 1)

LEFT JOIN SQLUser.PA_AdmPackage ON (PAADM_RowID = PACK_ParRef)

LEFT JOIN SQLUser.MR_Adm on MRADM_ADM_DR = PAADM_RowID
