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.

Hey Community,

See how cubes are constructed for use in business intelligence, and learn about SQL and MDX query languages. Physical and virtual cubes are used in InterSystems IRIS® Business Intelligence and Adaptive Analytics:

Hi Community,

See how the new embedded Python feature enables you to write user-defined SQL functions and stored procedures in Python:

Image search like Google's is a nice feature that wonder me - as almost anything related to image processing.

A few months ago, InterSystems released a preview for Python Embedded. As Python has a lot of libs for deal with image processing, I decided to start my own attemptive to play with a sort of image search - a much more modest version in deed :-)

Let's say we have two serial classes, one as a property of another:

Class test.Serial Extends %SerialObject
{
Property Serial2 As test.Serial2;
}

Class test.Serial2 Extends %SerialObject
{
Property Property As %String;
}

And a persistent class, that has a property of test.Serial type:

Class test.Persistent Extends %Persistent
{

Property Datatype As %String;

Property Serial As test.Serial;

}

So it's a serial, inside a serial, inside a persistent object.

It is often necessary to sort the results of a query on a string field containing a combination of alphabetic and numeric characters. In cases like this the default string collation may not always return the data in the expected sequence.

An example of this may be where a select from Samples.Person should order the results by the street address, but firstly ordered by the street number part as numeric, and then by the street name.

The default query will return the results as follows:

Hello,

So i want to use the INSERT OR UPDATE command so i can update a COUNTER for a given name:

INSERT OR UPDATE myTable
SET name='Omer', counter = counter + 1;

as you can see with the above code - if the row is non-existent then we get an error because COUNTER is NULL!
I tried the following to fix this but all have failed:

Hi Everyone!

In the modern world, the most valuable asset for companies is their data. Everything from business processes and applications to transactions is based on data which defines the success of the organization's operations, analysis, and decisions. In this scenario, the data structures need to be ready for frequent changes, yet in a managed and governed way. Otherwise, we will inevitably lose money, time, and quality of corporate solutions.

Problems with Strings

I am accessing IRIS databases with JDBC (or ODBC) using Python. I want to fetch the data into a pandas dataframe to manipulate the data and create charts from it. I ran into a problem with string handling while using JDBC. This post is to help if anyone else has the same issues. Or, if there is an easier way to solve this, let me know in the comments!

I am using OSX, so I am unsure how unique my problem is. I am using Jupyter Notebooks, although the code would generally be the same if you used any other Python program or framework.

The TIMESTAMP type corresponds to the %Library.TimeStamp data type (=%TimeStamp) in InterSystems products, and the format is YYYY-MM-DD HH:MM:SS.nnnnnnnnn.

If you want to change the precision after the decimal point, set it using the following method.
