a couple of things to try:

• start with creating a logfile: DBI->trace(9, 'C:\dbitrace.txt')

• select only the one column TransactionID

  SELECT TransactionID FROM Transaction where TransactionID=?

  if you get all the rows back, then DBI is having trouble with one of the other columns in your query.

i suspect you may have a large value in a text column, larger than the default size specified by DBI. the logfile you created should have some interesting info about the problem.
