A free app for Android, by Sebastian Dombrowski.
The SQL Client app is a useful tool that can be used to easily access a database on your smartphone or tablet. You can connect to different types of DBMS such as Microsoft SQL Server, MySQL, PostgreSQL, and others. Once you have a connection established, you can use the app to create, edit, delete, and update tables and views. You can also export data from your database to a CSV file.
You are allowed to do Syntax highlighting, save SQL statements, and execute multiple SQL commands in one query.
