I am searching for command line tools to execute the script files in Sybase. If anyone could point me to a download links will help.
Sybase is actually not a database, since there are 3 different database from the Sybase brand: Sybase ASE, Sybase IQ and Sybase SQL Anywhere (Incidentally, Sybase has been renamed to SAP since quite a few years.)
For ASE, the standard tool for batch execution is isql -i. For IQ or SQL Anywhere, you can use dbisql -nogui. See the respective documentation for details.
