#ODBC

It would be convenient to be able to fetch the whole query result in one operation instead of looping through every row. A fetch_all() method or something similar would provide this functionality I guess. Is there a reason why this is not implemented?

I have a class with a string property with DISPLAYLIST and VALUELIST parameters specified.

When I query this class via ODBC I receive logical value as it is and not a display value.

Is there any way (without stored procedure) to get display value?

Hello everyone,

I'm trying to authenticate a user(Health Share clinician) from a Java Application. 

I 'm already connected to Caché and able to run SQL commands.

My question is: How can I authenticate a user using only SQL? In fact, what I want is verify if the users exists in the base and if the given password is the same used in Health Share.

There is a column 'password' in Security.users table but I'm not able to see its content, even so, I don't know which hash function to use to compare with.

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).

Does anyone know of  way to create a connection to an external DB without using a DSN?

I have a MySQL server with "posts" table.

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.

How do I synchronize deletions?

Problem: Caché instance connects periodically to an Oracle database via jdbc and downloads data. Sometimes data on a remote server would change.

Hi!

Is there any simple way to query data about processed messages in all Ensemble productions?

What I ultimately would like to do is to periodically export that data to another system and run statistics on it.

I've been digging around in the SQL tables view and Ens.MessageHeader seems to contain most of what I'm after.

Using ODBC I could access that table view and query data, but only for one namespace per DSN it seems.

Can Ens.MessageHeader from different namespaces be mapped into a single namespace so that it can be accessed with ODBC?

Or is there a better way to access this data than
