Re: Append a list of tables to an empty table to form a whole table - Mailing list pgsql-sql

Hi,

again: Use EXECUTE! It's well documented here: https://www.postgresql.org/docs/15/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN

In your case, you can simply replace your INSERT statement by the following:

    EXECUTE 'insert into em_table as select * from table ' || a_name;

Hope this helps.

How best to append a list of tables to an empty table to form a whole table?

Pseudo codes show the desirable logic.

There are a list of tables with exactly same colums

table_a

table_b

table_c

Create an empty table  emp_table

Foreach a_name in ARRAY ARRAY['table_a', 'table_b', 'table_c'] loop

   insert into em_table as select * from table a_name

end loop;

Can something like that be done is PostGIS?

Regards,

David
