in reply to DBI mysql truncation best practice?

As stated above, strict mode is the only way for it to happen (mysql 5 only)

<quote>"but both methods involve me doing work that the database should be able to do much better (since it is doing the conversion"</quote> that's why i switched to postgres. mysql4 has no way to stop that from happening, and throws no warnings. mysql5 has the strict mode, but it can be overridden unless you're a beast about security policy on the server ( which is annoying, as mysql starts with a very loose policy, and makes you tighten most every option )

the error messages from mysql are fairly worthless too - they're mostly error codes with a generic descriptor. its impossible to bugfix without googling their online documentation. on the other hand, postgres throws verbose errors with detailed descriptions.

a lot of people love mysql, i used to be one of them. then 3gbs of data got destroyed by truncation, bad foreign key support, and i went crazy trying to decipher the server messages. now i'm in the postgres camp and completely love it.

if you're on mysql4, consider switching to postgres (since you'd have to install a new db anyways). its got a steeper learning curve, but its totally worth it.

as far as the speed differences between the two - unless you're getting slashdotted , you shouldn't really notice anything.
