If you encounter difficulties with MyODBC, you should start by making a log file from the ODBC manager (the log you get when requesting logs from ODBCADMIN) and a MyODBC log.
To get a MyODBC log, you need to do the following:
Note that you probably want to restore the old `myodbc.dll' file when you have finished testing, as it is a lot faster than `myodbcd.dll'.
MyODBC
connect/configure
screen. The log will be written to the file `C:\myodbc.log'.
If the trace option is not remembered the next time you visit this screen,
it means that you are not using the myodbcd.dll
driver. Reread the previous step to verify that you have installed
`myodbcd.dll'.
Check the MyODBC trace file, to find out what could be wrong.
You should be able to determine what statements were issued by searching for
the string >mysql_real_query
in the `myodbc.log' file.
You should also try issuing the statements from the mysql
client
program or from admndemo
. This will help you determine whether the
error is in MyODBC or MySQL.
If you find out something is wrong, please only send the relevant rows
(max 40 rows) to the myodbc
mailing list.
See section 1.7.1.1 The MySQL Mailing Lists.
Please never send the whole MyODBC or ODBC log file!
If you are unable to find out what's wrong, the last option is to
make an archive in tar
or ZIP format that contains a MyODBC trace file,
the ODBC log file, and a `README' file that explains the problem. You can send this
to ftp://support.mysql.com/pub/mysql/secret/. Only we at
MySQL AB will have access to the files you upload, and we will
be very discreet with the data!
If you can create a program that also demonstrates the problem, please include it in the archive as well.
If the program works with some other SQL server, you should include an ODBC log file where you do exactly the same thing in the other SQL server.
Remember that the more information you can supply to us, the more likely it is that we can fix the problem!
