Data Virtuality Command Line Client (DSQL)
You are looking at an older version of the documentation. The latest version is found here.
DSQL is a command-line tool that can be used on both Windows and Linux. The batch/bash file is located in the %dvserver%/bin folder.
The tool is designed to run scripts from files; however, running single requests directly from the command line is also possible. Query results can be either shown on the screen or saved in a file.
Syntax
The command syntax differs for Windows and Linux.
