I want to show two table values in Admin grid using UI Component (which has no relation) so using union query it can be achieved. How to get the collection from two tables?

Table structure 1

  • I wouldn't use union. you should create a table view in your database and present this data in the ui component

  • I think your not able to understand my question. your talking about the single table, I want to show two table values in one custom admin grid which has no relation.

  • I do understand your question. but I would create a table view. just aggregate your data in said table view. If you need to, you can use UNION in the select of the table view

  • But I don't want to aggregate the data in the same table view as there are multiple tables to combine and show in admin grid as of now I am just trying with two tables.

  • Yes we need primary key and secondary(foreign) key reference for this.

  • @Amy, but you should have foreign key to join two or more tables.
