PERL DBI question

[YankeePride13]

Hello, currently I'm trying to use PERL to update my web sites database with new info. I am trying to update large numbers of rows, reading information from a text file, and it fails every time stating that I cannot update or insert a child row as foreign key constraints fail. However, if I feed it 1 row to update at a time, there is no problem. Does anyone know if this is a short coming of perl or is there a problem on my end?
