We are sorry to say this, at present there is no MyODBC samples available
for the public. We are in the plan of distributing some basic samples with
the next release version of the driver, shortly.
FYI, to establish a connection to MySQL through MyODBC, follow the following
instrcutions:
-- Download MyODBC driver from
http://www.mysql.com/downloads/api-myodbc.html
-- Follow the instructions from the online manual to install and configure
the DSN.
http://www.mysql.com/documentation/mysql/bychapter/manual_ODBC.html#ODBC
-- If you want to use it on Unix, configure the MyODBC with iODBC or
unixODBC. Please read the following archive which gives complete details in
setting up the MyODBC with iODBC/unixODBC:
http://lists.mysql.com/cgi-ez/ezmlm-cgi?5:mss:3657:200108:einnhiokafobjmjbmc
bm
-- Once DSN (lets say MyTest) as configured in ODBC.INI, write a simple
C-ODBC as given below and build it by linking through DM libraries. On NT,
use odbc32.lib.
Hope this helps you, let me know if you have any questions on this.
Regards
Venu

Generally for ODBC, here is the format of the connection string: "DSN=data_source_name;UID=username;PWD=password" where in DSN <-- Data Source Name UID <-- User Name PWD <-- Password On Unix, when you want to use MyODBC without any driver managers, then you need to link the MyODBC static library to your application, which will use only MyODBC at run time. On the other hand, when you are loading the MyODBC at run time through iODBC/unixODBC driver managers, you need to create the DSN for MyODBC by adding some fixed definitions to ODBC.INI and ODBCINST.INI (optional), which normally resides in /usr/etc directory, which inclides -- DSN name (user choise) -- Path and the file name of the MyODBC driver -- Listening protocal and port -- Server name -- Database name -- UserName and Password -- General Description (optional) and so on. So, when the ODBC application is linked with iODBC/unixODBC, at run time the Driver Manager(iODBC/unixODBC) validates the DSN given in the SQLConnect/SQLDriverConnect APIs and based on that it loads a particular driver by reading the driver/DSN related options from ODBC.INI Once this DSN validation (Loading the respective driver) is done means, MyODBC driver sends the following information to the server for the connection purpose by reading it from ODBC.INI: -- Host Name -- User Name -- Password -- DSN -- Database Name -- Listening port For more details about ODBC connection and its parameters, please refer to the following MyODBC online manual from MySQL AB. http://www.mysql.com/documentation/mysql/bychapter/manual_ODBC.html#ODBC If you need any further assistance, please send the comments to [EMAIL PROTECTED], that way it will be exposed to MyODBC community.
