Hi all,

I am using %Library.ResultSet to execute my query which I have something like this.
Query GetABC() As %SqlQuery [SqlProc]{

}

After I execute this query and a resultset it returns from this. Now What I want to know is the SQL statement which will have the values dynamically added into while execution.

Hi All,

I am facing some issues. I am having a SQL query that is executed using %SQL.Statement ExecDirect() method. Now I want to convert it into Embedded SQL using &SQL().
But where clause is dynamic in my case and It may contain 3-4 clauses.

Hi all, 

We are doing a SQL server upgrade to SQL server v.15 from a legacy server which had v.10 . I have our Cache server as a linked server int order to pull data from our system. When building out the ROWSPEC, I have my fields typed as %String with various lengths with one field having a max length of 15000. The SQL server is trying to interpret this as a text data type instead of varchar(n). Text is a depracated data type since SQL server 2008. The error below is produced when trying to query from this view

I'm trying to execute SQL on a EC2 via SSM:

import boto3

instanceid = "i-123456789"
sql = """SELECT path FROM Security.Applications WHERE ID = '/csp/sys'"""
template = """su - irisusr -c 'cat << EOF | iris sql iris -U %SYS
                """ + sql + """
                        q
                        EOF'
                       """
template = [line.strip() for line in template.splitlines()] 
template = """\n""".join(template) 
ssm_client = boto3.client('ssm') 
response = ssm_client.send_command(
            InstanceIds=[instanceid],
            DocumentName="AWS-RunShellScript",
            Comment=AWS,
            Parameters={'commands': template})

⏯ Projecting Data into InterSystems IRIS with Foreign Tables

Hi All,

I am trying to fetch resultset using the below code - 

set rs = ##class(%ResultSet).%New("Simple.Person:ValidateAge")

do rs.Execute()

it is giving me error while the same code I run it through iris terminal worked fine. 
I want to understand that problem behind this. Also how can I check the possible methods that I can use on 'rs' somewhat dir() does in python.

Hi everybody,

I am writing an SQL query of the following form:

SELECT
(SELECTCOUNT(*) FROM DataTable WHERE Condition1 AND Condition2),
(SELECTCOUNT(*) FROM DataTable WHERE Condition1 AND Condition3),
(SELECTCOUNT(*) FROM DataTable WHERE Condition1 AND Condition4),
(SELECTCOUNT(*) FROM DataTable WHERE Condition1 AND Condition5),
user.id
FROM UserTable user

Is "time" a reserved word in the %CONTAINS function?

When I run the following SQL query, I get 0 matching results

SELECT ID, text
FROM Test.Sentence
WHERE text %CONTAINS('time') OR text %CONTAINS('time ') OR text %CONTAINS(' time')

However, when I run a query where the search string contains words other than "time" alone, it returns the expected matching results

SELECT ID, text
FROM Test.Sentence
WHERE text %CONTAINS('providers time money') OR text %CONTAINS('providers time') OR text %CONTAINS('time money')

It also works if I try to search for "tim" or "ime"

Hi all,

I am using ExecDirect() method to get SQL resultset of type %SQL.StatementResult. 

now I am fetch a column something like this rs.%Get("Amount") but if amount column is empty then it is return me empty string. If There is any way to set something like this in IRIS rs.%Get("Amount",0.00) if that is possible.

Hello Everyone,

The Certification Team of InterSystems Learning Services is in the process of developing two exams focused on using SQL in InterSystems IRIS and we need input from our InterSystems IRIS SQL community. Your input will be used to evaluate and establish the contents of the exam.

How do I provide my input? We will present you with a list of job tasks, and you will rate them on their importance as well as other factors.

Hi all,
I am using ExecDirect() method to execute my SQL query which is something like "SELECT * from Account where AccountNumber = ? "
But when I am providing a accountnumber that don't exists it doesn't return anything as aspected. while I am trying to check resultset.%SQLCODE in this case it is giving me 0 not 100. What's wrong with my SQL query and Also I there any other Property through which I check for if my resultset is null or it has some values.

In show Query messages in the message viewer the head.%Id is always used. How do you do this via your own sql/objectscript as fast as the portal does a search as using dates searching Ens.MessageHeader on portal is slow. 

For instance if you try do a search saying (TimeProcessed >='2023-06-01 00:00:00.000' and TimeProcessed <'2023-06-02 00:00:00.000') it is slow but using the portal the search would know this is head.%ID >= 5344549861 AND head.%ID <= 5347641372. How do you utilize this in your own queries as can't see the logic in EnsPortal.MsgFilter.Assistant

For volatile tables (tables with many INSERTs and DELETEs), storage for bitmap indexes can become inefficient over time.

For example, suppose that there are thousands of data with the following definition, and the operation of bulk deletion with TRUNCATE TABLE after being retained for a certain period of time is repeatedly performed.

Hi All,

I am trying to execute my SQL query using ExecDirect() method and it returns a ResultSet. No doubt it works fine after this I am trying to fetch each value using a loop code below. But before that, I am also checking for %SQLCODE = 100 which is for an empty resultset I think. However, It is not working as desired. In the case of an empty resultset also I am getting %SQLCODE = 0 until result.%Next() is called. Also, %ROWCOUNT is giving 0 in a case where my query is return 1 result row. I am so confused about this.
while resultset.%Next() {

// code

}

Countermeasures against SQL injection have been published on various websites, but we believe that it is possible to prevent SQL injection in applications using InterSystems SQL as well as other RDBMS by implementing these countermeasures appropriately. In addition, InterSystems Data Platform (hereinafter referred to as IRIS) incorporates several measures that make SQL injection more difficult than general RDBMS.

Query cache can be purged programmatically using the Purge* methods of the %SYSTEM.SQL class.

*For details of each method, please refer to the following documents.

%SYSTEM.SQL class【IRIS】

%SYSTEM.SQL class

① When deleting all query caches in the system

Do $SYSTEM.SQL.PurgeAllNamespaces()

② When deleting the query cache in the namespace

// delete all cached queries in namespace
Do $SYSTEM.SQL.Purge()
// when deleting the query cache specified by date
// the following deletes the cache not used in the last 30 days
Do $SYSTEM.SQL.Purge(30) 

Last week at the InterSystems Global Summit, we announced our new Foreign Tables capability, which was introduced as an experimental feature with the 2023.1 release earlier this year. We're now inviting you to join the Early Access Program for Foreign Tables and kick the tires on this new capability, so you can let us know whether it suits your needs and what capabilities we should prioritize next.

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.

DECLARE CURSOR C1 IS
SELECT Name FROM Person WHERE Name LIKE 'A%' FOR UPDATE
OPEN C1
LOOP FETCH C1 INTO name　
... show name
... EXIT the LOOP when finished
END LOOP
CLOSE C1

Ran into an issue with our upgrade from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect 2022.1, that I thought I would reach out about, I already have a ticket open with WRC and started a chat on Discord. We have a couple of MS SQL tables that I have setup as Linked Tables within Cache to query NPI, Patient Account Information, Visit information, etc... When we upgraded last week we found that within a day or even a half a day that we were having problems with our JDBC connections.

How to read the HL7 V2.5 messages irrespective of message type to Iris database ?

Source system sends HL7 messages of multiple message types to Intersystems through TCP and these messages are to be inserted/read into iris SQL database.

Hello,

Do you know if there is any way to disable the automatic tuning IRIS is doing every time a class is altered? It just takes too long in our case and is holding the system, so I'd like to tune the tables when I decide it (again).

I've seen in the documentation that for 2023 version there is an option present in the backend. But not for 2022, so I assume a flag is needed somewhere.

Many thanks!
