sx8000 is a command-line tool for executing SQL queries, and exporting the query results to CSV files. This tool is written in pure-Java and utilizes standard JDBC APIs. The name sx8000 comes from the belief that this is probably about the 8000th tool implemented which does something similar. (kudos to pg8000)

• Utilizes Java's standard JDBC API, requiring no additional installations other then the Java Runtime Environment.
• JDBC libraries can be added/swapped/removed on the fly.
• Configurable via launch arguments. No configuration files nor environment variables are required.
• Query can either be supplied as a one-liner command line argument, or from a text file.
• Automatic/configurable escaping of the CSV column values.
• Automatic/configurable output file compression from the filename. (.deflate / .gzip / .bz2)
• Automatic/configurable checksum file generation. (cf: example.csv.gz.sha256)

• JRE 8 or later.
• JDBC driver library. (Derby / H2 / HSQLDB / PostgreSQL / MySQL drivers are included in the archive.)

Download or build the archive file. Move into the archive's root directory and execute the launch script.

unzip sx8000-${VERSION}.zip

cd sx-8000-${VERSION}

sh bin/sx8000

Usage summary will be displayed to the standard output when the script is launched with zero arguments. Specify at least one of the parameters to actually execute the tool.

sh bin/sx8000 --out "./foo.csv.gz" --statement "select now()" 

sh bin/sx8000 --out "./bar.csv.gz" --statement "filepath:path/to/hoge.sql" --checksum "false" 

JDBC driver libraries can be added/changed/removed on the fly. The JDBC driver files can be found inin ./lib directory of the unzipped archive. Modify the jar files in this directory and adjust the CLASSPATH variable in the launch scripts. Older version of the JDBC drivers may require explicitly specifying the driver class name.

sh bin/sx8000 --driver "org.h2.Driver" --url "jdbc:h2:mem:" --out "./hello.csv.gz" --statement "select 'Hello World!' as Greeting"

• JDK 8 or later.
• Internet access for downloading the dependencies from Maven central repository.

Clone the repository, and execute gradlew clean build command. Archive files will be generated under ./build/distributions/ upon a successful build.

sx8000 is not...

• a GUI application.
• a scheduler. Use crontab or other scheduling middleware for automation.
• secured nor protected. Arbitrary query (cf: drop table ...;) can be executed without any validation.
• for everyone. Think twice and use at your own risk.
