A question has come up that I am not finding the answer for.... Does the daily purge process re-index EnsLib.HL7.SearchTable or other SQL tables? In looking at the purge process documentation I am not seeing anything that mentions EnsLib.HL7.SearchTable. Do we have to manually constantly re-index tables that we create? For example I created another search table based off of EnsLib.HL7.Search table, will I need to constantly watch this as it grows? How do tables get index, is there some kind of mechanism that automatically does it, or are we responsible for indexing tables ourselves?
I'm using an embedded SQL statement with a a cursor-based Embedded SQL query that uses host variables in the where clause, however, what I'm doing doesn't seem to work. Can anyone help?
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:
I am experiencing a problem with an EDI process that uses a SQL Batch Service to connect to our DEV environment. However, when we point the EDI service to our TEST server, it errors out.
I have checked every single property on our TEST and DEV servers as well as the properties on the associated tables. They are identical. Nothing has changed in the SQL either.

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.
What is the SQL table name for it? How can I obtain it via ObjectScript?
A quick search doesn't show any methods and properties. Documentation is a bit "wrong" here saying that the SQL table name is the same. It will be at least 'x_y.z'.
Finding errors in your code or examining unexpected behavior is the main purpose of Debugging I will try to refresh the traditional tools away from the helpers you have in Studio, VScode, Serenji, .... to the basics which have been there before your preferred EDI used it in the background.
