AnalogX SQLCMD allows you to quickly and easily run SQL queries against ODBC data sources. Basically, it's a simple portable way to execute SQL commands from batch files, etc.

SQLCMD is like most command line utilities out there; from the command prompt you can type the name by itself to get a list of options:

F:\tools\sqlcmd> sqlcmd

AnalogX SQLCMD version 1.00 (Release)
The latest version can always be found at http://www.analogx.com/

Usage:   SQLCMD [options]
Options: /USER [name]          Username to login as
         /PASS [password]      Password for username
         /DB [database]        Name of ODBC connection to use
         /LOG [filename]       Log results to file
         /APPEND               Append results to file
         /SILENT               Do not decode results
         /COMMAND [cmd]        SQL command to execute

Here's a brief description of each option:

    USER        This is the username to login to the database with.  This field
                is optional and will try to log in using a NULL account when it
                is not supplied.
    PASS        Password for username specified above.
    DB          ODBC Database to connect to.
    LOG         Specify the filename to log to.  Useful for debugging or keeping
                track of operations performed.  While not a log in the normal
                sense, it outputs all information pertaining to commands run.
    APPEND      Instead of overwriting the existing log file, it will append
                onto it.
    SILENT      Suppresses all text output.
    COMMAND     SQL query to perform

It's all pretty straight-forward (to my thinking, at least). Here's a couple of examples:

    sqlcmd /log "C:\Logs\sqlcmd.log" /append /db "Website" /command "select * from [users]"

or:

    sqlcmd /user Jimmy /pass Password /db "Website" /command "update [users] set Downloads=1"

also, if you execute it like so:

    sqlcmd /user Han /db "Website"

without the /COMMAND then it will go into it's "interactive" mode, where you can just enter in SQL queries. Once in this mode, simply type 'QUIT' and it will exit.

If the program thinks it has successfully executed the command, it will return 0, otherwise it will return 1 (these are normally the defaults for success and failure for command line programs), so it should be easy to include SQL commands into batch files.
