#SQL

I would like to integrate SQL into our ObjectScript routines in order to illustrate how SQL can be used to minimize development time. However, there are two questions I have.

1. How does one iterate through the results of a SELECT statement?
2. How does one access a Table in another namespace?

Hello, I need to use IRIS to connect to an MSSQL base.
It has to be done via ODBC, I can't use JDBC at this time by client option.

I am trying to use Microsoft Driver
libmsodbcsql-13.1.so.9.2

But I can't, my attempts result in:
Connection failed.
SQLState: () NativeError: [11001] Message:

I have done all DSN configuration, and my configuration is listed in SQL Gateway Connections. I know it's working, because when I run a test with isql I have the information that connects to the bank.

Is it possible execute create table from management portal?

I tried this:

CREATE TABLE SQLUser.Teste(ID INT NOT NULL, coluna1 VARCHAR(255), coluna2 VARCHAR(255), coluna3 VARCHAR(255), coluna4 VARCHAR(255)CONSTRAINT TestePK PRIMARY KEY (ID))

Error message:

on red hat, but I would also be interested in a wider answer.

after running a benchmark for 40 minutes, I have been asked if any rollbacks occurred in that time. Rollbacks from SQL or objects.

The application does not record this, so I am looking for a system level record.

The journal entries do the necessary reverse sets and commit just like any transaction. So i don't think i can detect them there.

Would like to know if there is an alternative or better way to paginate through a dataset using dynamic SQL than what I am using below. The problem is that as the potential pool of data gets larger, this code slows down to the point of not being useable. In analyzing each line of code below, it appears the slow down is related to the initial rset.%Next() iteration. Is there anything available which does not require a subquery/%VID such as a simple LIMIT/OFFSET?

My code is similar to :

s sql=##class(%SQL.Statement).%New()

Just wondering an Insight in the difference between these two indexes

IdKey / PrimaryKey
=================

Property Identifier As %Integer

Index Index1 on Identifier [Idkey]

Index Index2 on Identifier [PrimaryKey]

What's the difference?

1. If I don't have Index1 and only have Index2, then cache does still make its own id.
So how and why do I ever use the PrimaryKey. In Joins ??

Does anyone know if there is a table or query to get the Application Error Log (^ERRORS) by SQL?

What is the recommended approach to handle the following scenario: Large number of HL7 messages are serviced via Ensemble. Those messages are then transformed and routed to an Operation which calls a web service which does a number of different activities. If will do address normalization, location geo coding, MPI lookup and resolution, and insert into a SQL Server database to stage for an analytics product. Unfortunately all of this work takes time and the first thing that happens in the web service is a lock taken out on the Patien in SQL Server.

Let's imagine you have only SQL. You need some table where you should increment value in some property when you update this line.

We have the table

CREATE TABLE "test" (
  "identifier"   VARCHAR(200) NOT NULL,
  "value"        INTEGER,
  PRIMARY KEY ("identifier")
)

Hi, I’m trying to setup a Business Operation where the Property is a drop down list of Strings. I was able to produce the desired effect but only using a hard coded list like Property LookupProp As %String(VALUELIST = ",value1,value2"). Instead I would like i

Hello,

I have a global whose structure is multi-level and I am trying through a class and a SQL query to display a table which includes all the values ​​and levels.

I have to connect to an external database and I'd like to use the JDBC SQL Gateway.

I followed this tutorial [1] to create a JDBC SQL Gateway and after configured it works as expected, but I don't know

how use this connection into source code. Maybe these other tutorial is related [2] and [3].

I'm trying to have my REST service return the entire data set for one of our legacy globals. Currently I am parsing the object from a SQL statement into generic objects to be returned like this:

Hello, we have a few hundreds of triggers to port from Oracle to Cachè for a migration project, and many of them have to change (for example, normalize a value, null it, etc) the value which is being inserted.

The documentation says "You cannot set {fieldname*N} in trigger code." , so we're unlucky.

Is there a good workaround for this ?

SqlComputeOnChange doesn't seem the best way, but I'm not totally sure: for example normalization and validation could have a better place somewhere else than a trigger.
