[Zope] dtml Z SQL doubt

[Allen Schmidt Sr.]

Just use REPLACE instead of INSERT.
If REPLACE statement is able to determine a unique value for a row and 
sees that that unique value exists for a row, the valued will be 
updated. If it does not exist, a new row will be inserted. This is what 
I use with MySQL.
