isql
The isql utility is a command-line SQL client for c-tree SQL. Using the proper queries it’s possible to manage all database items, like tables, users and triggers.
Usage:
isql [-s<script>] [-u username] [-a passwd] port@ipaddress:databasename  | 
Where:
•	script is a text file encoded with UTF-8 that contains SQL commands to execute. This feature is useful if you need to launch one or more SQL commands without user interaction.
•	username is the login user, e.g. ‘admin’
•	passwd is the login password, e.g. ‘ADMIN’
•	port is the port on which the c-tree SQL Server is listening, e.g. ‘6597’
•	ipaddress is the address on which the c-tree SQL Server is listening, e.g. ‘localhost’
•	databasename is the name of the c-tree SQL database, e.g. ‘ctreeSQL’
If the login is successful the following prompt will appear and you will be able to input SQL commands:
