Interactive SQL (dbisql) is a utility for sending SQL statements to the database server. You can use this utility to:
Browse the information in a database.
Try out SQL statements that you plan to include in an application.
Load data into a database and carry out other administrative tasks.
In addition, Interactive SQL can run command files. You can build repeatable scripts to run against a database, then use dbisql to execute these scripts. See “Saving, loading, and running command files”.
