#SQL

on red hat, but I would also be interested in a wider answer.

after running a benchmark for 40 minutes, I have been asked if any rollbacks occurred in that time. Rollbacks from SQL or objects.

The application does not record this, so I am looking for a system level record.

The journal entries do the necessary reverse sets and commit just like any transaction. So i don't think i can detect them there.

Hi, I have used CSP to exec SQL selects from any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:

DSN CLIENT ONE

DSN CLIENT ONE

CSP Webpage:

TEXTBOX: Introduce your select:

One of my colleagues had developed an interface in Health Connect (HealthShare 2019.1) to add large amounts of data to an external SQL Server database. The data comes from many text files with delimited rows and data for one table per file. There is a business process to read a file line by line and send an Insert Request to an operation.

Hi ,

I have a code written in cache sql and trying to understand it, below is the code , can anyone help me understand what does that mean

ex - !! dosage_unit !!

SELECT (CASE WHEN (order_description IS NULL OR (order_description='')) THEN '' ELSE (order_description) END) !! (CASE WHEN (dosage IS NULL OR dosage_unit IS NULL OR (dosage='') OR (dosage_unit='')) THEN '' ELSE (', ' !! dosage !! ' ' !! dosage_unit !!

Thank You in advance.

Hello,

I am trying to work out if there are any methods available to be able import a result set returned by SQL query into a persistent class.

I have to connect to some legacy SQL databases through SQL Gateway and run some queries. I need to inster the rows returned into a class to then be able to do a %JSONExport to produce a JSON object. I know I can iterate through the resultset and insert one row at a time into the class but was wondering if there is any other/direct way of importing the resultset rows into a class.

Regards,

Utsavi

When i use ##class(%SQL.Statement).%New() -> .%Execute() and then .%Next() to go through the result set, i could only go through part of the result. And then, i have to call

In the Inbound SQL Adapter settings, is it possible to specify more than 1 field as the Key Field Name?

Because of the way the Query is being index in Ensemble by the Key Field Name, sometimes transactions get missed and I would like to see if we can add an additional key to the mix to ensure all the transactions are picked up. In this case the InterfaceTrigger is an ID that is auto generated by the table, and I would like to use that as well to ensure we don't miss transactions, and it does not throw any warning messages when it executes the Delete Query.

Since SELECT ... FOR UPDATE is implemented in many RDBMS as a method of explicit row lock acquisition, I think there are many cases where this function is used.

This syntax is not an error for InterSystems products, but it does not acquire row locks as expected.

This article will show you how to achieve equivalent functionality.

Dear Experts,

I have to pull out a report of certain code tables and this is my first script and I need to write many.

1. If I have to refer to the table, seeing the reference in the components with reference to SQL table and column,

can I use Select < What I need from the table>

Inner join with reference table?

I tried, I used the code table reference in the components, but I am getting errors,

Hi, we are a veterinary lab and we use both the LAB and FIN systems of Antrim. Now we are looking to expose the data in a SQL/Object compatible way so we were wondering if same / similar things had been done by other community members already? If so, could you please share your approach / experience / gotchas with us and we are all ears. I can be reached at yang.jiao@antechmail.com . Thank you!

In this article I will explain the usage of %SQL_Diag.Result and %SQL_Diag.Message table along with all-new LOAD DATA functionality.

It is recommended to go through LOAD DATA documentation first.

After successful operation LOAD DATA insert one record in %SQL_Diag.Result table and details are inserted in %SQL_Diag.Message table

Below is the basic command when table is already created and source file does not contain header row.

LOAD DATA FROM FILE 'C://TEMP/mydata.txt' 
INTO MyTable

The file name must include a .txt or .csv (comma-separated values) suffix and both source and target have the same sequence of data columns.

Loading from File Source: Header

Greetings all,

I have a quick SQL question. I am working with a class, which has a calculated property, which in turned indexed.
The calculation for this property is created based on another property value via:
SqlComputeOnChange = attributes - so basically every time I add a property attribute to my class, my new property
is calculated based on some SqlComputeCode which calls some class method.

That initial setup works as designed.
