SQL

Syndicate content 29 

I have a class that has a property calledTags (like DescriptiveWords, but tags), where multiple tags are possible.  I am trying to decide on list of Objects vs. array of Objects.

Based on this post: https://community.intersystems.com/post/querying-list-property-sql, sounds like using an array of Objects is the better way to go. Indeed, I already noticed that it's not possible to have duplicates when using an array of Objects.

I am trying to fetch the data from cache database. But i got the error like "CSP application closed the connection before sending a responce".

Below is the query.

SELECT
CallbackComment
FROM SQ.CBPhoneResult_View Where PhoneDateODBC = '2018-04-09'

I have investigated and found that "CallbackComment" contains the special character single quotes " ' "  for one result and due to this i got this error.

In this field data is enter by customer. so we cannot restrict them like Do Not use single quotes.

I have a serial object:

Class EmbedObj Extends %SerialObject

which is stored as a  property of another object

Class ContainerObj Extends %Persistent

Property InnerObj As EmbedObj;

Property Foobar As %String;

Question:

From within the context of an instance of EmbedObj, how can I navigate to the containing instance of "ContainterObj" and find that value of its Foobar property?

I have several stored procedures that when I execute them they will only return a single snapshot. In my BP I have been setting this to a Snapshot variable then looping using a WHILE through the snapshot variable just to get that single value.

Since it is only a single row, is there an easier way where I don't have to do a WHILE loop to pull the values out of that row? Can I call First Row or something like that to get me just the row into the Snapshot variable?

Hi Everyone,

I am trying to built a SSIS package thru BIDS Visual Studio 2013. My Datasource is a InterSystems Cache Database, I wanted to Import Tables records from the Datasource to MS SQL Server 2014.

As a Sanity check. I only created one Package to import one Table to MSSQL Server to try out. The connection to the InterSystems Cache Database was successful. The DSN for the InterSystems Cache Database is created in the System for 32 and 64 Bit.

The Art of Mapping Globals to Classes (4 of 3)

The forth in the trilogy, anyone a Hitchhikers Guide to the Galaxy fan?

If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.

If the above does not sound familiar to you please start at the beginning with the following:

Without installing Kerberos has anyone Authenticated a SQL JDBC connection? Currently we are using local SQL Accounts to sign onto External SQL Databases, but we are being told that we need to switch to Service accounts that live on a Active Directory Domain. 

I wrote with a little help a ZAUTHENICATE to do the Authentication for Ensemble, can I use something like that to connect to an External SQL Database using a Service Account on a Active Directory Domain?

Thanks

Scott

I  have generated a class using the linked procedure wizard however  I can't get it to work if the  datatype  of one of the parameters is VARCHAR(MAX).  It works fine if I change it to say VARCHAR(500) and  rerun the  stored procedure wizard. 

I get the following  error returned.:

ErrorMsg:   SQLState: (07002) NativeError: [0] Message: [Microsoft][ODBC SQL Server Driver]COUNT field incorrect or syntax error

Hi All

I'm looking for the a simple-quick-easy solution to monitor a SQL table thought Ensemble.

I have a process that update a DataBase ,a scheduled task that runs every night  (Not Ensemble)

In the end it updates a table (replica_status) with a new recored with two fileds:  Id, DateTime

I looked around the community but didn't find an answerd case.

I'm thinking on a Task that will run a sql outboud adapter BO that checks that table and send a alert if no new record was created yesterday

is this the right approach or is there's a better solution?

Hello Global masters!

I developed Web with Spring framework (JAVA, Jdbc Cache) and I wrote SQL when I made it.

And Window program with VB6, Cache Object and VisM.

Is there a significant performance gap? SQL and Cache Object?

same function, same computer performance just different Java and VB6.

Thank you.

Minsu.

Any insights, news, alternatives or experience about sequence pattern querying like with Oracle's MATCH_RECOGNIZE, more declarative, less simple direct COS way? Both obvious solutions (shadowing data to oracle cloud or implementing MATCH_RECOGNIZE compiler in COS from scratch) seem big overkill. Do Intersystems have plans to adopt this "2007 ANSI standard proposal" and "SQL:2016 standard"

I have a lookup table and record batch Table I would like to do a count on the records stored in that batch by counting the number of records in that batch that have  a certain key on the responseKey column. This column keys are stored in the look up table for comparison. So I would like to do a join sql pivot that will use my keys stored in the lookup as columns and count as values

so far I have managed to do this but this is not efficient I would like to fire that sql once not on every count

Hi,

The following sql statement is working through the SMP but couldn't make it work through the code.

The table is a linked table to oracle db.

Tried to change the date property in the linked table class from %Date to %String and also tried using %SQL.Statement and %Library.ResultSet

this work through SMP:

INSERT INTO PACKAGE.SOME_TABLE_NAME

(EFFECTIVE_START_DATE,MORE,DATA,HERE)

VALUES (to_date ('2018-04-01','yyyy-mm-dd'),123,456,789)

In the code i'm using '?' in the statement for the parameters.

How to convert SQL persistent classes to JSON output - I have tried 1 option but appears to be very lengthy process.

I have many other SQL storage's defined and have to expose them as well to JSON. Can anyone please suggest a better approach.

My column names usually match with my Json properties.

My User.TestClass is the class with GetJsonList() as my method to return /output JSON formatted data.

The Code tried and SQL storage structure are as follows -

This is a sample Ensemble/Health Connect production which demonstrates how to receive an HL7 order (ORM) inbound from a file, extract fields (in this case, basic demographic information), and insert those into a table in an external SQL database via ODBC.  

Included in the zip file:

  • Exported code
  • Sample ORM message

I am tasked with using CACHE to insert data retrieved from a CACHE data base and insert it into an sql database. The columns in the sql table that I am trying to insert data into have names that contain underscores such as "ACCESSION_DATE" I found a utility in CACHE to connect to the sql data base and perform inserts. I have the data I need to insert. I need to pass the  data into the sql utility referencing the column names.

I tried using indirection to set the data into underscored variables, but that isn't allowed  in cache object script.
