I need to do an UPDATE via SQL and I would like the statement to return the `ID` column of each row that is updated. MS SQL has an "OUTPUT" statement, but I don't see anything similar in Cache. Is there a way to do this?
I have setup an async reporting mirror member with Read only access. My problem is that if I try to do any sql reporting against that data I am getting errors. I am sure that this is because the DB is read only, but I had assumed that setting up a reporting mirror would handle this.
I have been using the query below and it was working fine but now it's giving a SQL error. There were no changes made that could cause this to stop working. There is no Field 'APPLICATIONID' in the table.
QueueSQL=select distinct (convert(char(5),SkillsetID)+'='+Skillset) from iagentbySkillsetStat where ApplicationID > 10000
QueueMappingSQL=SELECT DISTINCT (convert(char(5),SkillsetID)+'='+Skillset), SkillsetID FROM iagentbySkillsetStat iagentbySkillsetStat WHERE (iagentbySkillsetStat.ApplicationID>10000)
We are creating a package (written in Caché Object Script) that will provide access to an external DB (MySQL). Because applications that use our package will be run from machines with various, potentially unexpected, operating systems, we’d like to establish a connection to the external DB without using DSNs (we’ve heard that setting up DSNs on certain non-Windows machines can be cumbersome and problematic).
I want to query the cache database for messages where a specific HL7 segment equals a specific value. Does Cache have a pipe to XML or hl7 segment query function?
I'm trying to perform a SELECT with parameters using the EnsLib.SQL.OutboundAdapter. The SELECT returns results but seems to discard the parameters I try to send. I have tried two methods.
First:
Set par(1) = "20160630" Set par(1,"SqlType") = 12 Set sql = "SELECT Cod, Ing, score FROM [bbdd].[dbo].[vw_Test] WHERE MyParam >= '?'" Set tSC = ..Adapter.ExecuteQueryParmArray(.QueryResultSet,sql,.par)
Hi, after installed Healthshare 2015.2, all the tables previously correctly listed working with Healtshare 2014.1 are NOT listed anymore. TrakCare tables are not listed in the catalogue, nor by the WinSQL Intellisense.
Does anybody know a trick or have a hint to resume this useful functionality back?
Earlier in this series, we've presented four different demo applications for iKnow, illustrating how its unique bottom-up approach allows users to explore the concepts and context of their unstructured data and then leverage these insights to implement real-world use cases. We started small and simple with core exploration through the Knowledge Portal, then organized our records according to content with the Set Analysis Demo, organized our domain knowledge using the Dictionary Builder Demo and finally build complex rules to extract nontrivial patterns from text with the Rules Builder Demo.
This time, we'll dive into a different area of the iKnow feature set: iFind. Where iKnow's core APIs are all about exploration and leveraging those results programmatically in applications and analytics, iFind is focused specifically on search scenarios in a pure SQL context. We'll be presenting a simple search portal implemented in Zen that showcases iFind's main features.
I also have a Caché server with "downloadedposts" table.
They are connected from Caché to MySQL via SQL Gateway
I want to keep Caché table synced with MySQL one (MySQL "posts" table is a master copy), so periodically Caché queries MySQL server and downloads data. So far so good, and if a record appears or changes in MySQL table, Caché downloads the changes.
The problem I'm encountering is that sometimes rows would be deleted from MySQL "posts" table.
Recently I have been posting some updates to our JSON capabilities and I am very glad that so many of you provided feedback. Today I would like to focus on another facet: Producing JSON with a SQL query.
I'm trying to rewind a cursor back to the first row after looping part of the way through the implied result set, but I'm not finding a way to make this happen, is there some such iterator variable or directive that I can leverage to accomplish this?
I could code around it by pulling identifiers and/or values into a local array, and then hand code up an iterator over my local results copy, but this feels like a "redesigning of a wheel" approach, and I thought I would check before I start down this path.
The field test of Caché 2016.2 has been available for quite some time and I would like to focus on one of the substantial features that is new in this version: the document data model. This model is a natural addition to the multiple ways we support for handling data including Objects, Tables and Multidimensional arrays. It makes the platform more flexible and suitable for even more use cases.

Disclaimer: This article uses Russian language and Cyrillic alphabet as examples, but is relevant for anyone who uses Caché in a non-English locale. Please note that this article refers mostly to NLS collations, which are different than SQL collations. SQL collations (such as SQLUPPER, SQLSTRING, EXACT which means no collation, TRUNCATE, etc.) are actual functions that are explicitly applied to some values, and whose results are sometimes explicitly stored in the global subscripts. When stored in subscripts, these values would naturally follow the NLS collation in effect (“SQL and NLS Collations”).
Hello, is there a way to reset all of the Sample Classes back to their "Installed State."? In other words, delete all the other classes I have put into the samples namespace and leave only those classes that were there when I installed the instance.?
We are sometimes asked for examples of how to do 3rd party SQL database selects/updates/inserts/stored procedures from an Ensemble SQL Business Operation.
In the attached file there are 4 sample Ensemble Operations that demonstrate four different types of transactions with an external SQL DB:
Recently I was asked by a customer with this question. In MS SQL Server, there is a function called host_name() that will return the work station name.
Here is how I would do it in Caché :
With default SQL schema name, in my case SQLUser in SQL (which is equivalent as User in Caché class definition), I have a class called User.dummy, I added a classmethod called hostname and expose it as SQL function host_name:
This is a bit weird. I'm trying to use `DATEDIFF()` to calculate the time since the last message on an interface. For some reason, when no messages are received, the number steadily decreases. This is the opposite of what should happen. Here is my current query and a few sequential result sets:
SELECT getDate() as now, max(TimeCreated) as latest, DATEDIFF (s,getdate(), max(TimeCreated)) as difference
FROM EnsLib_HL7.Message
If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.
Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance. %NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.
Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.
