#SQL

13

SQL is a standard language for storing, manipulating and retrieving data in relational databases.

Hi, we are a veterinary lab and we use both the LAB and FIN systems of Antrim. Now we are looking to expose the data in a SQL/Object compatible way so we were wondering if same / similar things had been done by other community members already? If so, could you please share your approach / experience / gotchas with us and we are all ears. I can be reached at yang.jiao@antechmail.com . Thank you!

Hey Developers,

See how you can get high-performance relational access using SQL to manage data within your InterSystems products:

Hi, I have used CSP to exec SQL selects from any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:

DSN CLIENT ONE

DSN CLIENT ONE

CSP Webpage:

TEXTBOX: Introduce your select:

Credentials - Domain Account

Hi,

I've a Service utilising the Adapter EnsLib.SQL.InboundAdapter, which uses a Credentials item set with the details of a local SQL account. This currently works, however, we're looking to use the credentials of an AD domain account.

The domain account is a member of an AD security group, which has the required permissions on the source SQL database. I've checked that access is possible with this account via SQL studio.

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

Hello,

When i click on the menu to run the Data import wizard from MP, i receive following CSP error

<UNDEFINED>zOnPageHEAD+229^%cspapp.exp.utilsqleximwizardcontent.1 *schemaname : CSP Error

It is happening for all the namespaces. Looks like some permission issue. Same issue with Data Export wizard. Help to resolve this will be appreciated.

I am using

Cache for Windows (x86-64) 2017.2.2 (Build 865_0_18763U)

Thanks,

Hi Community,

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

Hello,

I am trying to work out if there are any methods available to be able import a result set returned by SQL query into a persistent class.

I have to connect to some legacy SQL databases through SQL Gateway and run some queries. I need to inster the rows returned into a class to then be able to do a %JSONExport to produce a JSON object. I know I can iterate through the resultset and insert one row at a time into the class but was wondering if there is any other/direct way of importing the resultset rows into a class.

Regards,

Utsavi

I've setup ODBC connection so I can access Cache data within SQL Server.

I want to be able to write SQL queries for internal monitoring purposes, similar to what's possible with SQL Server. Specifically I want to be able to check mirroring status (i.e. check which is the current primary mirror member), check the status of any Ensemble productions (started/stopped), check the status of business hosts etc. I want to do all of this from SQL Server to go with our other system monitoring solutions.

InterSystems FAQ rubric

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.

Sql request

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,

I have created a view to stage some data in a different format and then want to reference that view in a SQL query from a table that filters the data from the view using a property of the table.

Example:

select
MsgId,
FileName,
(select
ReportName
from
custom_view
where
MsgId = ReportId
) as ReportName
from
main_table

Is this even possible? When I try this, I get an error table not found for the view?

Cache Query for HL7 NACK

I would like to capture any NACK's that is sent back to the Operation. The Operation is already setup to "Save Replies/IndexNotOK's", but I would like to see if we can query Cache and pull those NACK's into an extract.

Is this possible?

Thanks

Pandas for KPIs in InterSystems IRIS BI

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.

In Cache 2018, we were using a macro in a query that looked like this:

select $$GetExtraSQL^GetExtra('B',bddtl.odnumb,bddtl.odsnum,bddtl.oddsc1) as "Description", * from sqluser.bddtl

We could save that query as a view, and there was no problem with it.

In IRIS, if we put that query into SQL in the management portal, it still works, but if we save that query as a view, when we try to run a query on that view, we get a big error message:

When using "IDENTITY" as my primary key, I can select the last inserted ID with

SELECT LAST_IDENTITY() FROM %TSQL_sys.snf;

Actually this is how Hibernate + Iris' Driver acquires the inserted ID when mapping with

@GeneratedValue(strategy = GenerationType.IDENTITY)

Now, considering that I am using the type "SERIAL" as my primary key instead, how can I get the last inserted ID?

Note that with "SERIAL" I can forcefully insert any value for this ID, from which Iris will continue generating values...

In this article I will explain the usage of %SQL_Diag.Result and %SQL_Diag.Message table along with all-new LOAD DATA functionality.

It is recommended to go through LOAD DATA documentation first.

After successful operation LOAD DATA insert one record in %SQL_Diag.Result table and details are inserted in %SQL_Diag.Message table


Below is the basic command when table is already created and source file does not contain header row. 

LOAD DATA FROM FILE 'C://TEMP/mydata.txt' 
INTO MyTable

The file name must include a .txt or .csv (comma-separated values) suffix and both source and target have the same sequence of data columns.

Loading from File Source: Header
