Hi Ken,
the reason you lose your data is simple. You have something of the form:
$myscalar = "A weird hested hash";
you then try to add an entry by doing:
$myscalar = "Some other data";
What you look at it like that, it's clear what is going wrong. What you
want is:
$tablename{$table}{"con_name"} = ["constraint_name"];
<Happy to explain hested hashes off list>
