INSERT INTO demo_tab SELECT demo_tab_row.*;
I tried this before with no success.
But I realized that it was because a problem with a constraint, no warnings
about this at all.
With the detailed insert i've got the constraint error.
I was using the execute because I had a variable called the same as a field,
not good, I changed it.
So now it's working perfectly!!!
Thanks a lot guys!
