Question

I have table v_c_country with column table_name

I can make an query and, as result, have the list of all tables from column table_names. Generally, it means. I have it as source to another query.
But what in situation when the list of table_names are different than list of original exists tables f.ex. from information_schema.tables? (f.ex. we prepare info about tables witch will be create in the future).

How to make a query on table v_c_country with result a list of table_names but verified with f.ex. information_schema.tables? (list only with names of real existing tables)
Example pls.

Answer 1

select c.table_name from v_c_country c
inner join INFORMATION_SCHEMA.TABLES i on i.TABLE_NAME = c.table_name
