I was dealing with MySql and had this problem a while ago Thread ID: 1448957

Don't know if this will help your situation but the MySql ODBC driver has a checkbox to "Change BIGINT Columns To Int"

Also, I'm pretty sure it was Eric Selje who also pointed me to

lcConnString="Driver=MySQL ODBC 3.51 Driver;Server=xxxx;UID=xxx;PWD=xxx;DATABASE=xxx;APP=xxx;Option=16384"
lnHandle = SQLSTRINGCONNECT(lcConnString)

as a way of getting this behavior without having to modify the ODBC driver. He had a list of what the various options were (based on power of 2 schema) but unfortunately I've lost the link to it.
