create table sintax

Hello,

 

If I run

 

create table newtable (like oldtable including constraints);

 

in the SQL window with works just file.

But if i execute

 

execute 'create table '||newtable||' (LIKE '||oldtable||' including constraints)';

 

inside a function, in a LOOP, the constraints aren't created.

What is the problem?

Tanks,
