The Interactive SQL (ISQL) tools are installed with the ODBC, ADO.NET, and JDBC Clients and can be valuable for troubleshooting.
The Interactive SQL tools are OpenAccess SDK Client programs for accessing data resources managed by OpenAccess SDK Servers. These tools use a command line interface to connect to a data source, execute SQL statements, and retrieve results for display on a terminal. The tools can also be used to verify installation and to execute SQL commands interactively or from a file.
Note: The ADO.NET Client does not have an Interactive SQL tool at this time.
