mssql

This is a Java Command Line client for accessing MSSQL Databases using the JTDS JDBC driver.

Usage: java -jar mssql.jar [OPTIONS...] [COMMANDS...]

-o --out       Name of the file to redirect output to.
-u --user      Username to connect with.
-p --password  Password to connect with. If none is given
               the password is read from terminal.
-P --port      The port on which the remote database is running.
-h --host      Host to connect to. The hostname may contain the port
               separated by a colon or a comma.
-d --database  The database to use on the remote machine.
-U --url       The JDBC url used to connect with the database.
               This will override all previously set credentials.
-f --file      Read configuration from the specified file.

Building

mvn assembly:assembly
mv target/mssql-jar-with-dependencies.jar mssql.jar

Usage

Once you fired up a terminal you can invoke mssql like explained above, for example:

java -jar mssql.jar -f myconnection.properties

where myconnection.properties contains the credentials to you MSSQL database:

hostname = your.database.host:port
database = DATABASE
username = USERNAME
password = PASSWORD

You can also give the password on the command line or just specify the -p command line switch without supplying a password - mssql will ask for it on the console then.

For simply looking around and investigating a database mssql offers a few special commands that look like their mysql equivalents:

DESCRIBE table;
SHOW TABLES;

You can also dump a schema in XML using

DUMP regex;

For example

DUMP .+

to obtain the structure of the whole database.

Commands can also be specified on the command line, thus

java -jar mssql.jar -f connection.properties 'DUMP .+' > struct.xml

will dump the structure of your database into struct.xml.

Any other query works too:

java -jar mssql.jar -f connection.properties 'SELECT TOP 10 * FROM [mytable]'

If commands are ommitted on the command line, mssql will run in interactive mode and offer a terminal for communicating with the database server.

Result sets are printed one row per line, columns separated by tabs.

-U can be used to specify your own JDBC connection url. By default the following is being used:

jdbc:jtds:sqlserver://%s:%s;ssl=require;databaseName=%s;user=%s;password=%s
