MySQL Connector/ODBC Developer Guide
To enable the trace option on OS X 10.2 (or earlier) or Unix,
add the trace option to the ODBC
configuration:
On Unix, explicitly set the Trace
option in the ODBC.INI file.
Set the tracing ON or
OFF by using
TraceFile and Trace
parameters in odbc.ini as shown
below:
TraceFile = /tmp/odbc.trace Trace = 1
TraceFile specifies the name and full
path of the trace file and Trace is set
to ON or OFF. You
can also use 1 or
YES for ON and
0 or NO for
OFF. If you are using
ODBCConfig from
unixODBC, then follow the instructions
for tracing unixODBC calls at
HOWTO-ODBCConfig.
