#SQL

I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. I am having trouble with a specific table. When I need to query this specific table for specific fields, I am receiving an error. However, if I change the call to get all columns (`*`), there is no error. I get 37K records returned.

Error:

I have been following the online Zen Quickstart Tutorial using the lastest release documentation. In addition to playing around with the styling and making a few minor functionality tweaks, I wanted to add an additional column that shows a count of the number of phone numbers for that Contact (as shown in the image below).

Hi,

Is there a way to find the median in Intersystems Cache SQL? I know it is not available as an aggregate function. Also in SQL Server I could try something like:

SELECT
(
 (SELECT MAX(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score) AS BottomHalf)
 +
 (SELECT MIN(Score) FROM
   (SELECT TOP 50 PERCENT Score FROM Posts ORDER BY Score DESC) AS TopHalf)
) / 2 AS Median

However, there is no PERCENT Keyword in Cache as well. Any suggestions?

Thanks

Pandas is not just a popular software library. It is a cornerstone in the Python data analysis landscape. Renowned for its simplicity and power, it offers a variety of data structures and functions that are instrumental in transforming the complexity of data preparation and analysis into a more manageable form. It is particularly relevant in such specialized environments as ObjectScript for Key Performance Indicators (KPIs) and reporting, especially within the framework of the InterSystems IRIS platform, a leading data management and analysis solution.

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:

Hi All, I am a Data Architect and am trying a method of deploying alter statements onto Cache DB.

My Data Modeling tool generates alters as this.. So question is if the Cache has a way to rename table? If so what is it?

ALTER TABLE <SchemaName>.GROUP_TYPE_NODES RENAME TO GROUP_TYPE_10082019140110000
;

This is giving error.

Hi!

I have a question regarding SQL insert/update from the mananger portal's SQL window.

I am trying to do an insert with a value that contains multiple spaces ($32) between two words. This is needed for a comparative reason. But the spaces are automatically trimmed away all the time. How should I write to keep these?

Example:

Insert into TableA
(MyColumn) Values('xxxx yyyy')

then the spaces are trimmed away and it becomes: 'xxxx yyyy'

But I want to keep the spaces. How do I get around the problem?

Regards,
Michael

I cannot get any further hint from the error message in red in this screenshot. Is there any clue or details about the connection failure that I could look for?
