Command line to change path to .mdb file for MS Access ODBC System DSN?

问题

What odbcconf.exe command line can I use to change the path to the MS Access .mdb file for an already existing System DSN?

回答1:

To answer the question as asked, here is a solution using odbcconf.exe instead of going straight to the registry:

odbcconf.exe configsysdsn ^
  "Microsoft Access Driver (*.mdb, *.accdb)" ^
  "DSN=OurConnectionName;DBQ=X:\Path\to\OurMsAccessDB.mdb"

Two items of note which had me tripped up for a while:

make sure you use 64bit odbcconf.exe when on a 64bit system, see https://stackoverflow.com/questions/6721702/windows-7-64-bit-odbc-drivers-for-ms-access-missing.
use DBQ= and not Database= for the mdb path. When using the latter everything appears to work, however the connection link is named but not actually defined in the ODBC Administrator.

You would have to do it by changing the registry. Something along the lines of this example taken from the net that I have used before

rem -----Author: Jim Michaels
rem -----copy the drivers where all good little ODBC drivers go
if errorlevel 1 goto bye
copy myodbcd.dll C:\WINDOWS\SYSTEM
if errorlevel 1 goto bye
rem ----create a .REG file to make registry entries
echo REGEDIT4>myodbc.reg
echo.>>myodbc.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\MySQL]>>myodbc.reg
echo "APILevel"="2">>myodbc.reg
echo "ConnectFunctions"="YYN">>myodbc.reg
echo "Driver"="C:\\WINDOWS\\SYSTEM\\myodbc.dll">>myodbc.reg
echo "DriverODBCVer"="02.50">>myodbc.reg
echo "FileExtns"="*.txt">>myodbc.reg
echo "FileUsage"="0">>myodbc.reg
echo "Setup"="C:\\WINDOWS\\SYSTEM\\myodbc.dll">>myodbc.reg
echo "SQLLevel"="1">>myodbc.reg
echo.>>myodbc.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers]>>myodbc.reg
echo "MySQL"="Installed">>myodbc.reg
echo.>>myodbc.reg
rem -----install the registry entries by executing the .REG file
start /wait myodbc.reg
rem ----clean up after we are done installing
del myodbc.reg
:bye

If you look at your existing DSN config in the registry then you will get an idea of how to modify the code to suit your situation
