Limiting the amount of data in a variable when logging slow queries

Hi,

We've enabled the slow query log and have a particular query that is
executing an insert against a table containing a binary array column.

Given the content being stored is upwards of 100MB+ this leads to very long
log messages for the slow query log.

Is there a way of having the slow query log only output the first 'n' bytes
of a byte array and/or exempting this particular insert?

Thanks,
