Re: Subversion > Bugzilla integration through MySQL

Hi Frank,

Looks like you have the following problematic lines:

my $statement = $db_handle->prepare($sql)
my $statement2 = $db_handle->prepare($sql)
my $statement3 = $db_handle->prepare($sql)

When you call execute() on your db handles, you are using the values
held in $sql each time instead of $sql, $sql2, and $sql3.

Change those and you should be all set!
