Sql Server table-valued parameter

Postby Janssenjos » Wed Oct 26, 2022 11:12 am

Hello,

Does anybody know if it is possible to use Sql Server table-valued parameters from within Servoy? https://learn.microsoft.com/en-us/sql/relational-databases/tables/use-table-valued-parameters-database-engine?view=sql-server-ver16
I have been looking through the documentation and at first glance I can't really find that it is possible.

Our specific use case is that we build up a custom sql query in code with parameters and use the DatabaseManager.getDataSetByQuery.
We have also looked into the rawSql plugin.

But in this use case we have some set based considerations, which can variate to larger sets. In which we could simplyfy our code if we can use table valued parameters.
Now we have a sql query with 10-to-60 parameters, which vary on each users settings. With use of a defined type, we could always have 1 parameters for the query. (Which also boosts reusability in sql server for query plans/caching: better performance)

Using table valued parameters seems the most obvious/simplest solution, hence we want to ask if it is possible first before looking for other solutions.

We are running the latest LTS (22.3.x)
