Thanks for your reply, I tryed it and modified it for my needs, but this is result:
--error message
SQL error:
ERROR: subquery in FROM must have an alias
HINT: For example, FROM (SELECT ...) [AS] foo.
In statement:
create temp table t1 as
select * from (select f_table_name from geometry_columns intersect select jmeno from tables) as tmp_foo;
select * from (select f_table_name from geometry_columns except select jmeno from tables)) as tmp_foo1
union
select * from (select jmeno from tables except select f_table_name from geomety_columns) as tmp_foo2;
I was traying somethin like this, but it looks like wrong way:
SELECT f_table_name FROM geometry_columns WHERE (SELECT jmeno FROM tables) NOT IN (SELECT f_table_name FROM
geometry_columns);
Thank you for your help
