Olá a todos!

Estou com dificuldades de fazer meu select para retornar palavras que contém acentos.

Na minha tabela TESTE, por exemplo, tenho palavras no campo NOME como Fábio e Fabio, porém se eu coloco a instrução:

SELECT * FROM TESTE
WHERE nome LIKE 'FÁBIO'

a instrução só traz FÁBIO.

Como eu faço para trazer todas as palavras: FÁBIO, FABIO, FABÍO, FABIÓ, FÁBÍÓ, FÂBIO, etc...

Conto com sua ajuda!

Hello everyone,

I am looking for the syntax or the way to use a class created in the "BNA" Namespace (my application) from the %SYS Namespace.

Here is the context:

I have a "BNA" application contained in the "BNA" NS, this application provides a user creation functionality. This feature creates both the user in a table in the application and in the Iris system.

Overview

Encryption of sensitive data becomes more and more important for applications. For example patient names, SSN, address-data or credit card-numbers etc..

Cache supports different flavors of encryption. Block-level database encryption and data-element encryption. The block-level database encryption protects an entire database. The decryption/encryption is done when a block is written/read to or from the database and has very little impact on the performance.

With data-element encryption only certain data-fields are encrypted. Fields that contain sensitive data like patient data or credit-card numbers. Data-element encryption is also useful if a re-encryption is required periodically. With data-element encryption it is the responsibility of the application to encrypt/decrypt the data.

Both encryption methods leverage the managed key encryption infrastructure of Caché.

The following article describes a sample use-case where data-element encryption is used to encrypt person data.

But what if you have hundreds of thousands of records with an encrypted datafield and you have the need to search that field? Decryption of the field-values prior to the search is not an option. What about indices?

This article describes a possible solution and develops step-by-step a small example how you can use SQL and indices to search encrypted fields.

Hi,

My doubt is about the SQL Query in Caché:

I don't want to take all results from the table and orgainze them manually, for example: I have a table with 50 records, but I only want to select 10 records, being from tenth until the twentieth and this without knowing their IDs.

So, how can I do this, without losing performance, there is any way?

JDBC counts don't match

I'm using a JDBC driver to connect PGSQL -> Cache. I'm noticing when I run SELECT queries and COUNT(*) command against the same table, I get different result sets. I'm pretty new to Cache in general - so I'm trying to understand why these would be different.

Examples (TransID and InvNum should occur in every "row"):

SELECT COUNT(*) FROM ACCT.Services = 1,090,324 WHERE ACCT.Dept = 483

SELECT TransID FROM ACCT.Services = 1,085,776 WHERE ACCT.Dept = 483

SELECT InvNum FROM ACCT.Services = 586,023 WHERE ACCT.Dept = 483

I have a NewBie Question.

I have been playing around with "Basic CLass Queries."

I have defined a very simple "Basic Class Query." (see below)

However, I cannot find in the I/S documentation how to execute this query.

Any help is appreciated.

Hey,

I have a value in epoch time in which I need convert in order to be able to lookup a table that has dates in YYYY-MM-DD HH:MM:SS format

I thought the below would work but it is not.

select COUNT ('Arrival Time') FROM dbo.table where 'Arrival Time' < DATEADD(ms, CONVERT(int,LEFT(1603173432000, 20)), '1970-01-01 00:00:00')

sql insert from cache

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.

I've been accessing Cache tables from a developer/reporting side, but am now involved in a project to create a data warehouse for our application. I'm trying to find a query I can use to return the sizes of all the tables in the database, so we can identify the largest tables and handle those individually. Can someone give me a query I can run against our Cache database to return the sizes of all the tables from largest to smallest?

Thanks for the help

Force inner select to be executed

I have a query that I am attempting to run, but inner query is being rolled up into the overall query - per the optimizer (and jobexam observation). While I know that if the inner query runs first, I will eliminate a number of records (making the result set smaller, and return quicker).

Just an example of what I am attempting to do:

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?

Timing of Database look up

We use a lot of external MS SQL calls to look up numerous things when it comes to HL7. I am running into an issue where the outbound calls are queued but the message is sent onto the next process before it gets a response. How do I get it to wait till the response gets back from the MS SQL call before sending it onto the next process?

Below is a screen shot of what I am trying to explain...Select Research Study executes at 8:33 the message is sent to the next process at 8:34, but the response of the MSSQL call doesn't come till 9:31.

Hello, I am running into a little problem.

I am trying to create a Cache Trigger on a FACS table using the SQL CREATE TRIGGER command but I am getting the message [SQLCODE: <-300>:<DDL not allowed on this table definition>].

I am not creating a persistent class but using the SQL CREATE TRIGGER command.

Please advise.

thanks.

Hi!

I'd like to know if there are any issues if an index is inserted into a table without running the %BuildIndices() method.

It's important to note that data inserted before the index is not important for retrieval, so it's not a problem data inserted before the index don't show up in queries.

The reason why I'm asking this is that I'd like to avoid index reconstruction on big tables which I need to inser such index.

I'm using Cache 2018.1.

Thanks,

José

I need to run a SQL query and use the output to map PV1 7.1. The query is :

SELECT ID
FROM TestTable
WHERE ProviderName = 'TEST,PROVIDER' AND IDType= 'BPI'

When I run this query with the 'TEST PROVIDER' I do pull the ID in question but I can't figure out how to do it from the DTL given that there are various providers sent in PV 1 7 . Any assistance will be greatly appreciated.
