We want to do the same for the COLUMNS, but there is no predefined stored procedure for the public columns dependencies. The only available is `COLUMN_DEPENDENCIES` stored procedure which return private views. Hence, Is there a stored procedure to do that? Or how to elemenate the dependency on the private views so that all the direct dependencies are public views?

Snowflake 2. Postgres 3. MySQL 4. SQLite3 Able to copy a table from the MySQL data source to the Postgres data source using create_remote_table() without any issues. But when attempting the same from Snowflake; basically from the Snowflake data source to the same Postgres data source, the following error is encountered - ERROR: java.sql.SQLException: Error executing query. Total time 7.03 seconds. QUERY [SELECTION] [ERROR] CREATE_REMOTE_TABLE [STORED_PROCEDURE] [ERROR] CREATE_REMOTE_TABLE [STORED PROCEDURE] [ERROR] Received exception with message 'Error executing VQL query. QUERY [VIRTUAL] [ERROR] QUERY [JDBC WRAPPER] [ERROR] QUERY [JDBC ROUTE] [ERROR] Received exception with message 'Cannot invoke "com.denodo.vdb.engine.thread.IWorker.stop(int)" because "this.worker" is null'' I know Denodo Express has some license-restricted limitations and thought maybe this was one of them but given the MySQL/Postgres create_remote_table() success I'm thinking it is likely something else but that error message is challenging. Java version (Express): version=17.0.12 Snowflake driver in Express: version=3.14.3 Postgres driver in Express: version=42.7.2 Queries against the Snowflake data source in Express work smoothly both through VQL Shell and Design Studio as well as with JDBC clients connected to Express. Same for the Postgres data source. Any thoughts as to what is going on?

Our Denodo TEST\PROD are both set to Restricted. We use Denodo VCS for our promotion strategy. DEV views when promoted to TEST\PROD retain their Unicode query behavior (meaning to successfully query the field names must be in double quotes and are case sensitive) as opposed to adopting that of the host which is set to Restricted. I have found that if I edit the promoted view(s) in TEST\PROD and resave them, then and only then do they adopt the charset of the host which in this case happens to be Restricted. I have validated identifier charset settings at both the server and the vdb levels for each environment to ensure this is not playing a role.

I have created a derived view in which, for one of the field, I have a requirement to strip a part of the string. That is, I have a string "domain_name\first_name" in one of the fields and am trying to create a new field by taking only the first_name and append "@gmail.com" at the end. The new column would look like 'first_name@gmail.com'. I tried using SPLIT function to split the string using "\", but that gives me an array and am not able to take just one element in the array. Is there a better way of doing it?
