@section Connect parameters for MyODBC
One can specify the following parameters for @strong{MyODBC} on
the @code{[Servername]} section of an @code{ODBC.INI} file or
through the @code{InConnectionString} argument in the
@code{SQLDriverConnect()} call.
@multitable @columnfractions .2 .2 .6
@item @strong{Parameter} @tab @strong{Default value} @tab @strong{Comment}
@item user @tab ODBC (on windows) @tab The username used to connect to @strong{MySQL}.
@item server @tab localhost @tab The hostname of the @strong{MySQL} server.
@item database @tab @tab The default database
@item option @tab 0 @tab A integer by which you can specify how @strong{MyODBC} should work. See below.
@item port @tab 3306 @tab The TCP/IP port to use if @code{server} is not @code{localhost}.
@item stmt @tab @tab A statement that will be executed when connection to @code{MySQL}.
@item password @tab @tab The password for the @code{server} @code{user} combination.
@item socket @tab @tab The socket or windows pipe to connect to.
@end multitable
The option argument is used to tell @strong{MyODBC} that the client isn't 100%
ODBC compliant. On windows, one normally sets the option flag by
toggling the different options on the connection screen but one can also
set this in the opton argument. The following options are listed in the
same order as they appear in the @strong{MyODBC} connect screen:
@multitable @columnfractions .1 .9
@item @strong{Bit} @tab @strong{Meaning}
@item 1 @tab The client can't handle that @strong{MyODBC} returns the real width of a column.
@item 2 @tab The client can't handle that MySQL returns the true value of affected rows. If this flag is set then MySQL returns 'found rows' instead. One must have MySQL 3.21.14 or newer to get this to work.
@item 4 @tab Make a debug log in c:\myodbc.log. This is the same as putting @code{MYSQL_DEBUG=d:t:O,c::\myodbc.log} in @file{AUTOEXEC.BAT}
@item 8 @tab Don't set any packet limit for results and parameters.
@item 16 @tab Don't prompt for questions even if driver would like to prompt
@item 32 @tab Simulate a ODBC 1.0 driver in some context.
@item 64 @tab Ignore use of database name in 'database.table.column'.
@item 128 @tab Force use of ODBC manager cursors (experimental).
@item 256 @tab Disable the use of extended fetch (experimental)
@item 512 @tab Pad CHAR fields to full column length.
@item 1024 @tab SQLDescribeCol() will return fully qualifed column names
@item 2048 @tab Use the compressed server/client protocol
@item 4096 @tab Tell server to ignore space after function name and before @code{'('} (needed by PowerBuilder). This will make all function names keywords!
@item 8192 @tab Connect with named pipes to a mysqld server running on NT.
@item 16384 @tab Change LONGLONG columns to INT columns (Some applications can't handle LONGLONG).
@item 32768 @tab Return 'user' as Table_qualifier and Table_owner from SQLTables (experimental)
@item 65536 @tab Read parameters from the @code{client} and @code{odbc} groups from @code{my.cnf}
@item 131072 @tab Add some extra safety checks (should not bee needed but...)
@end multitable
If you want to have many options, you should add the above flags! For
example setting option to 12 (4+8) gives you debugging without package
limits!
The default @file{MYODBC.DLL} is compiled for optimal performance. If
you want to to debug @strong{MyODBC} (for example to enable tracing),
you should instead use @code{MYODBCD.DLL}. To install this file, copy
@file{MYODBCD.DLL} over the installed @code{MYODBC.DLL} file.
