#SQL

When using CallableStatement to call a stored procedure, the log shows an error. SqlCode-400.

This is my calling statement.

CALL web_DHCENS_CDSS.patadviceinfo_patadviceinfo(?,?,?)

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.

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.

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?

Temporary tables are tables available for a current process only (and destroyed when process ends).

What are you approaches to creating temporary tables?

1. Process-private Globals storage can be used as a data global in storage definition. That way, each process can have its own objects for the class with ppg storage.  Here's how. Here's how 2.
2. InterSystems TSQL supports #tablename temporary tables. A #tablename temporary table is visible to the current procedure of the current process. It is also visible to any procedure called from the current procedure.

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

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

select dateadd(d,N.number,d.begindate) adate, data
  from data d
  join Numbers N ON number between 0 and datediff(d, begindate, enddate)

This code fetches a row for every day between the begin date and end date.

In T-SQL, I can create a recursive CTE to create a subquery or a view that will hold a whole lot of numbers.  Is there a way to do this in Cache SQL?  I'd like the numbers from 0 to 10000 if possible. 

Thanks!

Hi,

Do you have any experience in server side pagination with IRIS using Angular on the client side?
Any idea on a typical SQL request on the server side?

Thanks!

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'"

"Assuming network disconnect error based on: SQLState: (HY000) NativeError: [0] Message: [Microsoft][SQL Server Native Client 11.

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.

SELECT TOP 1000 %ID, DateOfSale, Outlet->City, %EXTERNAL(Channel) AS Channel, Product->Name AS Product, UnitsSold, AmountOfSale AS Revenue, (Discount * 100) || '%' AS Discount, Comment FROM HoleFoods.

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.

   &sql(DECLARE D1 CURSOR FOR SELECT A.SHIPMENTTRACKINGNO, A.SERIALNO, A.CDWACCNO, A.CDWINVOICENO, A.CDWORDERNO, A.CDWPARTNO INTO :context.

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.

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

HI I am using below code to retrieve the last inserted ID of the table. It works when we do not set any custom column as IDKey. If we define any column as 

IDKey below code does not return any IDKey. I know when i am defining any column as IDKey its not auto generated , but whats the best way to get the ID column value

            String sql = "INSERT INTO TestFramework_UI_Data.Execution (TotalTestSteps) VALUES (0)";
            //ResultSet rs = createExecutionSt.executeQuery("SELECT * FROM TestFramework_E2E_Data_TestData.TestCases");
            int t = createExecutionSt.

Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name.

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.

SQL provides %IGNOREINDEX, which allows me to ignore a specific index, but I don't need that.  I need the reverse - %CHOOSEINDEX so that I can force SQL to use a specific index.

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

Hello,

I have created my first table in Ensemble:

And I have added a row using the Production:

We would like to query it, and we would expect to get a row wih all the previous' image data.

I have tried, inside a code block in a Bussiness Process:

  set statement=##class(%SQL.Statement).%New()
 
  set status = statement.%PrepareClassQuery("TablasBBDD.NotificacionesPUSH.RelacionAplicacionNotificacion","seleccionarTodo")
 
  set result = statement.%Execute()
  do result.%Display()
 
  $$$LOGINFO("filas result: "_result.%ROWCOUNT)
 
  $$$LOGINFO("result: "_result)
 
  //$$$LOGINFO("clave: "_result.

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. 

I am trying to get a list of all settings for all the config items of a given production using SQL . When I run the following sql as a dynamic query I am unable to access the setting names and values. Settings is a list of Ens.Config.Setting

Set query="Select Name, Production, Settings,$ListLength(Settings) "
         _"As Count from Ens_Config.Item "

Set rc=##class(%ResultSet).%New()

Set sc=rc.Prepare(query)

Set sc=rc.%Execute

While rc.Next(.sc) {

For i=1:1:Count {

  Set tSetting=$List(Setting,i)

  Set name=tSetting.Name

}

I get a LIST error on the last line!

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:

Call module B, which populates bitmap temp-file A.
Read bitmap temp-file A, looping on ID.

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.

We are currently using Health Share 2018.1.3

Thanks

I like to use something like this:

select * from MyTable where MyFieldName like ‘%[^a-zA-Z0-9 !”%#$&”()*+,-./:;<=>?@]%’

to find field that contains special characters that are only allowed.

Hi All,

We have few queries which are simple selects . For simplicity let's say there is a query that joins two tables and gets few columns and both tables have no indexes.

Select Tab1.Field1, Tab2.Field2
From Table1 Tab1
Join Table2 Tab2
On Tab2.FK = Tab1.PK
When we do query plan for this it shows approx 6 million,  however if we make a simple adjustment to the query

Select Tab1.Field1, Tab2.Field2
From Table1 Tab1
Join Table2 Tab2
On Tab2.FK = Tab1.PK
WHERE Tab1.Id > 0 (Which will always be the case)

The query plan comes down to few thousands. So approx 99% improvement.

cache 2017.2.1 (Build 801_3)

when I look into the "sql statements" ( sql page of the management portal ) I have lots of old statements with a lot of them frozen. many of them are %sqlcq routines (I believe these are the SLQ's I run when testing/running random SQL queries in the sql page. )

I can clearly see where I can click on an individual query and untick an individual query to unfreeze it. or delete it. but thats a painful slow process.

I am working on a BPL to take data from a MS SQL database and create an HL7 Materials Message for our EMR.  I have done this plenty of times in the past however I am running into an error.

"Remote Gateway Error: JDBC Gateway SP execute(0) error 0: Access to the remote server is denied because no login-mapping exists."

What is confusing is that this BPL doesn't differ from any of my other BPLs in connecting to MS SQL Server. I know I am missing something..
