InterSystems Caché database is a file where all the data, application scripts, and users, roles and security configurations are stored. Typically the name of the file is cache.dat.
I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns.
Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.
Hi I am getting below error while upgrading cache instance. Please suggest.
Error: ERROR #70: *** Error while formatting volume because
ERROR #18: failed creating a new volume initializing CACHETEMP, /*****/databases/cachetemp/ - Shutting down the system
An error was detected during Cache startup.

We have a need to track Database changes over time - down to the SQL level of granularity if possible. Such as: User xyz runs routine ^abc and we get something similar to a changelog that tells us: table A had this value updated, insert, update etc....
Is that possible using IRIS level tools (Audit Log, Journal File, etc...) , is there a way to convert the global sets and kills from the journals into SQL level changes?
I am a beginner in cache. I need to extract data from multiple tables (4-5) tables based on an SQL query . The data is more than 9 lakhs of records (i checked using count). The total number columns is 16.
When I am running this SQL query through management portal, I am getting time out exception. Could you please suggest how I can retrieve those records. Which way will be good (Dynamic query using %SQL.Statement or Embedded SQL (not known to me) or Writing to a global will help or not).
I have a set of strings that contains special characters. Im trying to write a sql query to remove all the special characters in the string. Im using Intersystems cache sql.
Application to import 12 Datasets along with 43 tables dynamically by using LOAD DATA command which loads data from a source into an IRIS SQL table. List of Datasets
I get this on some queries in some namespaces. For instance, this query:
SELECT TOP 10 SessionId, datediff(s,min(TimeCreated),max(TimeCreated)) as ResponseTime FROM ens.messageheader GROUP BY SessionId ORDER BY ResponseTime DESC
It works fine in HSBUS but in HSREG it throws the error.

Does anyone know what would cause this? Would it log something more useful somewhere?
"SELECT * FROM wmhISTORYdETAIL" runs as a passthrough without asking for the DNS.
but
'SELECT Count([wmhISTORYdETAIL].[HistHMNumber] AS CountOfHistHMNumber FROM [wmhISTORYdETAIL] WHERE ((([wmhISTORYdETAIL].[HistMovType])='Receipt') AND (([wmhISTORYdETAIL].[HistMovDate])>=Date()-1) AND (([wmhISTORYdETAIL].[HistMovDate])<Date()));'
asks for the DNS but both are linked to a table that has the password saved.
I have a custom process that is parsing HL7 and inserting it into a table. Periodically the inserts fail with # due to error: ERROR #5803: Failed to acquire exclusive lock on instance of....
Traditional databases would wait until the lock is removed then do the insert, but cache fails. I'm sure it's my coding approach.
I know that 1-1 relationships are not officialy supported by intersystems cache/iris so I want to know the best way to store data with this kind of data model.
Currently I have two classes that where implemented some time ago:
Table A with a relationship type one on table B
Table B with a relationship type one on table A
To compile I have a double compile with qualifyer U.
What is the best way to implement a data model with 1-1 relationships?
Hi Cache team, I am in the need of listing all the user defined schemas that are present my Cache db and also the user defined tables and views and Columns of those tables and views through Queries. So that I can write some JDBC code to run the queries and fetch the above metadata. Any help is appreciated.
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.
We want to isolate the storage of our CCDAs from our HL7 V2 data, but keep them under the same namespace. From my understanding, I should create a new database then store those classes related to CCDAs in that database. Is this the correct approach?
Is there a way or can it be done to use conditional logic in sql like so
Query Q1(formal as %String) As %SQLQuery [ Final ]
{
SELECT patientnumber,ID, CASE
WHEN ID = 50 THEN "The is 50"
WHEN ID = 30 THEN "This is 30"
ELSE "The quantity is under 30"
END FROM Audit.Table WHERE ID = :formal AND EndDate is null}

We have Edge Production where we uploading flat files clinical data, and during testing we do this for several rounds load data, test them and reload them. So everytime we have to generate differnet patient data or change MRNs etc. So request is is there a command to delete patient records that will remove from the tables, and delete reference in the registery as well.
Any guidance that you follow for testing backload data and delete loaded data, pls share
I have a linked procedure class and SQL gateway setup and I can't seem to get any response, status or error from using the stored procedure, I think it must be something big I'm missing to not even get a status.
Can someone see what my problem is please, any help would be very much appreciated.
I need an example of what I need to "map" to have a common dashboard defined so it will visible/usable in multiple namespaces.
I have created a dashboard in "SAMPLES" (namespace and database) and I would like to have this dashboard be accessable/useable from a 2nd namespace, but I'm not having any success in doing mappings (global/package/routine/data) to be able to get DeepSee to be able to see/display the dashboard.
How do I organize a wildcard search with respect to a database search?
Example of what I am trying to do: s x=$o(^G("ABC","A*",x))
Trying to navigate through the ^G global for all occurrences of "ABC", and "A*" ("A"+wildcard) but I am new to M and don't know positively how to do this. Perhaps I don't use an "*" at all, rather; another convention altogether.
