#SQL

I'm participating in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during the training. Tips presented in the day 3:

1. You can see your class catalog using %Dictionary classes and see your sql objects into INFORMATION_SCHEMA table.
2. Is possible use SQL inside your ObjectScript methods using Dynamic SQL or Embedded SQL.
3. You can pass parameters into Dynamic SQL string using ? (eg.: where country = ?) and pass parameters to Embedded SQL using colon (ed.: where country = :variable).

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.

I have vendors asking for verification that messages for locations are coming through to them.  I can get generic ADT_A01 type of numbers in Activity.  I'd really like to get some good SQL queries that can give me a count of MSH.4s (for example) for a day for X Operation.  I'm not sure which table to look at for that information.

Hello,

I have established an ODBC connection with our client based on credentials they provided.    The test connection was successful and after using the Link Table wizard I can now see the client's tables and properties.    However when we try to execute a query in IRIS we are getting error code -226.   I'm trying to determine if this could be just a simple setting problem in IRIS or something with the client.   

We have tried with PostgreSQL as well as with TSQL.  Same result for each.

Has anyone seen this error before and could it be pointing me in a certain direction?

Hello all,

I have a Business Service which retrieves data via a SQL adapter and writes the data in text file. My production is doing the job, but instead of the Business Operation output being one file, I am getting many files, with 1 , 2 or 3 rows only. 

Any help is appreciated. 

Thank you 

Image search like Google's is a nice feature that wonder me - as almost anything related to image processing.

A few months ago, InterSystems released a preview for Python Embedded. As Python has a lot of libs for deal with image processing, I decided to start my own attemptive to play with a sort of image search - a much more modest version in deed :-)

A tast of theory 🤓

In order to do an image search system, fist it's necessary select a set of features to be extracted from images - these features are also called descriptors.

Hello fellow community members,

I would like to offer my services as an Intersystems Professional and am available to work on projects. 

I have more than a decade experience into  Intersystems stack of technologies including IRIS, Ensemble, Healthshare, Healthconnect, Cache Objectscript, Mumps, Zen, Analytics etc. with companies spread over US and UK  involved in multiple domains.

Hi Developers!

Here're the technology bonuses for the InterSystems Multi-Model Contest that will give you extra points in the voting:

• InterSystems Globals (key-value)
• InterSystems SQL
• InterSystems Objects 
• Your data model
• ZPM Package deployment
• Docker container usage

See the details below.

In the Inbound SQL Adapter settings, is it possible to specify more than 1 field as the Key Field Name? 

Because of the way the Query is being index in Ensemble by the Key Field Name, sometimes transactions get missed and I would like to see if we can add an additional key to the mix to ensure all the transactions are picked up. In this case the InterfaceTrigger is an ID that is auto generated by the table, and I would like to use that as well to ensure we don't miss transactions, and it does not throw any warning messages when it executes the Delete Query.

Thanks

Scott

Hi Everyone,

I am trying the Export and Import application as per this link referred here: ExImData

I have the following sample class I am trying to import:

Class Persistent.PersonBackup Extends %Persistent
{ Property Name As %String; Storage Default
{
<Data name="PersonBackupDefaultData">
<Value name="1">
<Value>%%CLASSNAME</Value>
</Value>
<Value name="2">
<Value>Name</Value>
</Value>
</Data>
<DataLocation>^Persistent.PersonBackupD</DataLocation>
<DefaultData>PersonBackupDefaultData</DefaultData>
<IdLocation>^Persistent.PersonBackupD</IdLocation>
<IndexLocation>^Persistent.

Does anybody know if there is an easy way to know if the execution of the command $System.SQL.PurgeForTable went well/wrong?

The documentation describes that a string is returned, but in fact there is a nice Quit "" in the code.

Maybe inside PurgeForTable^%apiSQL there is any process variable set when it goes well/wrong?

Thank you very much!

Since I'm just starting to use this aspect of IRIS I can't tell if this is a bug or some kind of nuance.  If I run a single column query like this, I get results:

However if I try to retrieve using a DISTINCT or GROUP BY, I get no results:

And again except with a GROUP BY, with no results:

If I add in some other columns I still get no results HOWEVER, if I add in a date column, I now get results:

What am I missing here?  Is this by design and if so, what governs whether a return set is returned or not?  I did purge my query cache in case something was happening there but it did not fix this.

DataGrip is a multi-engine database environment targeting the specific needs of professional SQL developers, DataGrip makes working with databases an enjoyable and productive experience.

To work with InterSystems IRIS from DataGrip you'll need to add InterSystems JDBC driver first (once per DataGrip) and after that add all your InterSystems IRIS connections.

Part 1: Add InterSystems IRIS JDBC Driver

1. Go To File → DataSources

2. Go to + → Driver

3. Set Driver properties:

• Name: InterSystems IRIS
• Class: com.intersystems.jdbc.IRISDriver

Given a complex method flagged with [ SqlProc ] so it is available as an SQL stored procedure, what's the best way to report a non-system error detected in that method - say, for example, an error %Status - so that the SQL query calling it fails descriptively? Is it best to create and throw an exception, or are there special % variables involved (like in a trigger)? I haven't been able to find an answer in the documentation.

Thanks in advance!

Hi,

The question is about queries on the System->SQL page. I have a class with a few columns on a global and the test output looks as expected, below. This works as expected as well returning a single row: select * from Utils.RoutineAuditReport where counter=4. However, other columns give an odd error like " Field 'AG' not found in the applicable tables^ SELECT * FROM Utils . RoutineAuditReport WHERE UserR = "AG". As you can see below, both the UserR column and the AG entry in it do exist. What could be the problem?

Thanks in advance,
Anna

I have an SQL text index defined like this

Index TextIndex On (Text) As %iFind.Index.Basic(IGNOREPUNCTUATION = 1, INDEXOPTION = 0, LANGUAGE = "en", LOWER = 1);

If I run a query like this:

SELECT
Text
FROM Post
WHERE %ID %FIND search_index("TextIndex",'ABC')

I get 20 results with posts containing the term ABC.

But each post can contain the term several times.

Is there a way to get a total count of ABC term?

Is there a way to get a count of ABC term in each Post?

I am trying to create an ODBC class that includes all of these as records, but I don't see how I can since the first record has 3 subscripts, the rest have 4 subscripts:

Here is my current storage definition:

<Storage name="Test">
<ExtentSize>100000</ExtentSize>
<SequenceNumber>25</SequenceNumber>
<SQLMap name="Test">
<Data name="ModificationDate">
<RetrievalCode> set {ModificationDate}={L4}</RetrievalCode>
</Data>
<Data name="Operator">
<Delimiter>":","|"</Delimiter>
<Piece>36,2</Piece>
</Data>
<Data name="CreationDate">
<Delimiter>":",","</Delimiter>
<Piece>24,1</Piece>
</Data>
<Data name="CreationTime">

Hi folks!

Do we have an embedded REST API in IRIS which accepts arbitrary SQL and returns data in JSON?

Or if anyone did something like this?

The idea is to have something like MDX2JSON but SQL2JSON.

Thanks!

I have a case where I need to look up the NPI provider against an External MS SQL database to retrieve our Provider Identifier to send to a downstream system. In the past I would use a Business Process (BPL) to connect to the outside MS SQL via JDBC and get that information for me. But I was thinking instead of creating a BPL process to do this, would it be better just to link to the outside MS SQL database table to retrieve the information in a SQL statement within a DTL?

So it is better to link to an outside database via a Linked Table wizard?

Hello community,

I need to know what permissions or resources, apart from read for the tables, a user would need to view the catalog via ODBC? The ODBC user can run queries sucessfully but cannot get the catalog from the DB via ODBC. Whereas a a user with %All can fetch the catalog.

Any help would be much appreciated.

Juergen

We are trying to convert some of our SQL Service Integration Service jobs from Visual Studio to Ensemble. If we execute a Stored Procedure within SQL Server Management Studio it is returning approx 12,000 rows. However when Ensemble executes the same Stored Procedure it is only returning 250 rows.

Is there a limitation to EnsLib.SQL.Snapshot?

This is how we are calling the Stored procedure

Method uspInterfaceEnsSelectPER355MC(pRequest As osuwmc.SSIS.DataStructures.InputPER355MC, Output pResponse As EnsLib.SQL.Snapshot) As %Status
{
Set SPQuery = "{ ?= call dbo.

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.

SQL Error [25] [37000]: [SQLCODE: <-25>:<Input encountered after end of query>]
[Location: <Prepare>]
[%msg: < Input (IDENTIFIER) encountered after end of query^ALTER TABLE xxx.GROUP_TYPE_NODES RENAME>]
 

Is it possible see the execution plan of a SQL sentence in IRIS?

Like this:

explain plan for
select  e.ename,r.rname
from    employees  e
join    roles       r on (r.id = e.role_id)
join    departments d on (d.id = e.dept_id)
where   e.staffno <= 10
and     d.dname in ('Department Name 1','Department Name 2');

That returns this:

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.

I've tested setting the Credential username as domain\username and username@FQDN, but neither create a successful connection.

In Oracle database, the synonym is an alternative name for objects such as tables, views, sequences, stored procedures, and other database objects.

You generally use synonyms when you are granting access to an object from another schema and you don't want the users to have to worry about knowing which schema owns the object.

Is IRIS SQL sintax has something like this: (oracle sintax)

CREATE PUBLIC SYNONYM suppliers
FOR app.suppliers;

This first CREATE SYNONYM example demonstrates how to create a synonym called suppliers

Hey Intersystems Community-Member,

Following Issue: When I update a SQL table like (update OnlineV3Admin.ParameterApp set popuptext = '' where ID = '1') and then read it for my Json WebService there is a /"x00" in my Json.

What is the best option to disable that? I need here  a empty String and not /x00.

Any ideas?

Best regards,

We use ExecureProcedure() to execute a stored procedure which returns a result set. But we see lot of "Invalid cursor state" errors when the result set is empty.  The connection to SQL server database is made through ODBC.

Hi,

InterSystems IRIS has long supported the obvious translation functions required to for converting to upper or lowercase to enforce case-insensitive string comparison (e.g. in ObjectScript with $zconvert) and sorting (e.g. with SQL collation functions, not to be confused with NLS collation). Customers in international contexts have at times used custom workarounds to also treat accent insensitivity or even more advanced normalization duct tape. We’re looking to address such use cases at the system and SQL level to increase convenience for this international audience, which is well represented on the Developer Community.
