Folks

I am trialling MySQL 5 before we all upgrade, however others need to import 
my dump files into their existing MySQL4.x databases

MySQL 5 mysqldump seems exports BIT fields as true = '', false = '\0'.

When  that dump file is imported into MySQL 4 these value are not 
interpreted correctly. MySQL4.x does not have a real BIT type , rather it 
uses TINYINT(1).
Both  '' and '\0' seem to be interpreted as "false", and the relevant 
TINYINT(1) field is set to 0.

So far that has meant that I have to hand-edit my dump file to convert  '' 
to 1,  '\0' to 0.

Does anyone know a way around this?



TIA - Adam Lipscombe
