Custom update in Transaction groups

[quote=“arian.mares”]I have a table named io with, aprox this structure:

io_id, io_name, io_value, io_tag_name.

This table have as many rows as many tags there are.

I’m trying to have always in this table the values for each tag.

There will be many tags (2000-3000).[/quote]

It sounds like you might as well just stick everything in a Database Driven Provider. Ignition will store all the tags in a table (sqlt_core) according to the schema found in this document.
