InterSystems IRIS 2020.1 brings a broad set of improved and new capabilities to help build important applications. In addition to the many significant performance improvements accrued through 2019.1 and 2020.1, we are introducing one of our biggest changes in recent SQL history: the Universal Query Cache. This article provides more context on its impact to SQL-based applications at a technical level.

Is there a way to query the database structure?  In SSMS there are queries for finding tables with a column with a certain name (using LIKE).  And there is the redgate tool SQL Search.  But I'm not sure how to go about looking for columns that have say a value of 'PATID' and returning all tables that match.  Does anyone know?

Hi All,

I need to build a search using a lot of filters, what's the best way to implement my sql requests.

1 sql request per property, or only one "big" sql request ?

what's the disadvantage of using lot of indexes ?    Thank you

KR,

Amine

Where can i get the latest odbc providers from SQL Server 2012/2016?

 

I see some posts on line to  an ftp site out there but I am unsuccessful at getting access to it.  I have a version loaded on my server but get errors when querying cache'.

"[Cache ODBC][State : 22005][Native Code 22005]" 

Any help would be appreciated.

the one we have might be version  2014.01.05851  64 bit (would that make sense?)

Let's say I start with a date range of '1-5-2019' to '5-25-2019' that occurs on one row.  I'd like to ultimately have this show as 5 rows in Crystal Reports as shown below

Result

1-5-2019  1-31-2019

2-1-2019 2-28-2019

3-1-2019 3-31-2019

4-1-2019 4-30-2019

5-1-2019 5-25-2019

 

I found a result that worked in T-SQL, but I'm not sure how to translate it to Cache SQL.  The T-SQL code is

Hi,

I created a BS with a SQL Inbound Adapter.

Query = "SELECT rowid, fname ,lname,datesent  
                   FROM labs
                   WHERE datesent IS NOT  NULL"

DeleteQuery = " update labs set datesent  =  Getdate() where rowid = ?"

KeyFieldName = "rowid"

i am getting the following errors.

"NOT assuming network disconnect error based on: Gateway failed: DropStatement."

"Skipping previously errored row '235'"

This error is sometimes seen while viewing a listing in InterSystems IRIS Business Intelligence:
ERROR #5540: SQLCODE: -99 Message: User <USERNAME> is not privileged for the operation (4)  

As the error suggests, this is due to a permission error. To figure out which permissions are missing/needed, we can take a look at the SQL query that is generated. We will use a query from SAMPLES as an example.

I have a code block in a BPL.  I have the below SQL and code.  All variables have been declared and set.  When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct.  If values are returned, I get a -400 error when I perform the first FETCH.  I've investigated, but cannot find the reason for a -400 error.  Hoping someone out here understands this and knows what's wrong.

In Episode 4 of Data Points, we welcome @Benjamin De Boe to the pod to discuss some of the things you can do to optimize your SQL queries in InterSystems IRIS. We've all heard — either from ourselves or from others — the "this runs too slowly" complaint. I thought Benjamin did a great job walking through many of the things within IRIS you can look at with your queries to see what can be improved.

I'm using Cache SQL and want the ability to choose a specific index.

I've boiled the problem down to one table and simplified the query down to

SELECT *
FROM Registration.PatResp
WHERE SchedApptNum=8450022

 

SchedApptNum is indexed, but instead of using that column, "Show Plan" indicates that it's looping through the entire Registration.PatResp table on Id (the primary key for the table).

I've done a tune-table with no change.

Hello Community,

Thank you all for your continued feedback and support of our ad hoc reporting platform, VDM.  There's been some questions around setting up a non-ODBC connection for InterSystems platforms.  We published a new YouTube video showing the steps necessary to connect to InterSystems Caché and InterSystem IRIS with BridgeWorks VDM.

How do you cancel a query that is executing in the Management Portal  > System  >  SQL?

Does closing the browser cancel the query or does it continue to run in the background?

Is there any added benefit to using the Shell over the Portal? Perhaps there is a way to cancel/stop a query here?

$SYSTEM.SQL.Shell()

  Thanks

Hi,

we're planning some work on our SQL Query Plan functionality for a future release of InterSystems IRIS and are interested to hear how you're using them today, or what'd keep you from using them. Rather than try and fit everything in a rigid survey, I thought a simple thread on our beloved DC might also reveal some use patterns that we support or could do a better job on.

A quick question regarding to SQL Query Plan:
Why these two requests have different plans, in particularly, why second request needs temp file? To me, temp file is a bad thing which should be avoided, right?

  1. select * from Test.Log where cdate = 1
  2. select * from Test.Log where cdate > 1

Plan for 1:

Read index map Test.Log.cdateIndex, using the given %SQLUPPER(cdate), and looping on ID.
For each row:
 Read master map Test.Log.IDKEY, using the given idkey value.
 Output the row.

Plan for 2:

Ok so I am way outside of my comfort zone, and had to build an application using CSP to give users the ability to access SQL configuration tables. These SQL Configuration tables will affect the data that is sent to the downstream system. 

I saw in the examples where we were able to import GIF's/IMAGES into the CSP folders to use as a reference in our CSP pages. My question is how do you do that? If I try to import through studio, it tells me the file is invalid.

Just trying to make it a little more user friendly then blocks on a page.
