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.
Why when I use a SQL on the Cache, the condition between "the expression" and "the expression", not permite to me, delete the all ID of this data class?
We are trying to track down the source of Orphaned messages and noticed that we are unable to query EnsLib.HL7.Message with any kind of WHERE or ORDER BY clauses in our SQL statement.
I know EnsLib.HL7.Message is a system table, but is there a way we can add additional Indexes to the table to make the query run better/faster without affecting the system?
I'm new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute.
Example:
Below would be the _sqltext
DECLARE @Id INT;
select id into @Id from something;
if @Id = 9
BEGIN
do something
END
The _sqltext would work in sql server, what would be the equivalent for cache for it work?
I want to have a script that can run from the usual unix, linux, or aix command line. It has to be able to get into an irissession and use set statements to get data using sql. It seems like I'm in a catch-22. When I use the irissession SERVER command at the command line, I can't run a script. When I put the irissession SERVER command in a script, it won't run anything in the script after that.
My goal for this script is to get this information and put it into a file which I can then parse.
Use case: small in-house hospital systems that query patient demographics via SQL. The new PAS being implemented in the near future will only support query/response via HL7. SQL access is available but intended for reporting so up to 24 hours behind.
Probably the easiest option is to set up a database in Ensemble and keep it up to date via standard ADT feed. This is going to have quite a large footprint and has a risk of getting out of sync.
I have a SQL query that I want to run against MS SQL from cache ensemble using the SQL outbound adapter. If I run this query direct from MS SQL Studio it take about 7 seconds MAX and returns about half a million rows. The row only contains one column it is a number all same size and if I run this query in the production in ensemble it takes for ever the production finishes without getting the response back. The same query run in cache outside the ensemble environment writing results to a file it returns results taking about 3minutes to complete.
Is there a way to use a class Parameter in embedded SQL without having to declare a local variable, in a similar way to how it is done with Property by preponing i% as described here. See my example:
We need to export last 5 days Ens.MessageHeader data for a specific messages into file. I have written custom code to execute SQL query in object script.
Could somebody help me to iterate resultSet and write the data to text file.
I've checked the syntax with some public tools with adjusted Tablename "Fehlermeldung" -> `Fehlermeldung`. It seems to be valid, but cache does not accept it.
II try to explore the new SQL LOAD DATA feature in SQL comparing it to SQL INSERT
I'm stuck at this point: INSERT INTO <table> (columns...) VALUES (.....) allows having not just simple column references but also ALL Standard SQL FUNCTIONS (at least) example:
INSERT INTO Test (ShortName,DOB)VALUES (SUBSTRING(Name,1,4),TO_DATE(displayDate,'MM-DD_YYY'))
This works perfectly. BUT the same VALUE clause applied to LOAD DATA fails in various ways:
Problem to Solve: When an HL7 message hits a particular Process, I need to use the placer order number therein to query the messages that came in over the last 24 hours on a particular Service and grab discrete pieces of data that came in the latest message that has that placer order number.
I have csv date file with date values like this "4/10/2021" for April 10, 2021. I defined a table with this property: Property TranDate As %Library.Date.
I capture error
[SQLCODE: <-104>:<Field validation failed in INSERT, or value failed to convert in DisplayToLogical or OdbcToLogical>] [Location: <ServerLoop>] [%msg: <Field 'dc_data_finance.transact.TranDate' (value '4/10/2021') failed validation Field ...
I do not really want to change TranDate to %String. How can I import "4/10/2021" into %Date property?
Hi all, I try to build a little project for the dataset contest, you can find it here on github: Openflights dataset My plan is to use just plain SQL. So I've made a few experiments with the new feature LOAD DATA.
Does anyone have an example of the method used to run an SQL query and generate the view in a Mumps routine. I have several SQL queries created from a vendor that need to be converted and the corresponding view referenced. I cannot seem to find any examples in IDX routines or in the IRIS/Cache documentation. Any help is appreciated.
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?
When i use &sql(SELECT ......) in Cache I can watch the generated code In the generated .int code and see what is happening. Just with my normal rights
Now in IRIS I have just 4 line calling some class %sqlcq.*** With enough rights i find there is no such class but the generated .int routine %sqlcq.IRISAPP.xEZgUjdXCCgQdZQPpRdOye1Ci2ue.1 That holds the code that i had in my .int on Cache
