SQL$ - SQL Database Interface

SQL$ API	Function
SQL$GET_ERROR_TEST	Retrieves the last SQL error message
SQL$GET_ERROR_TEXT	Retrieves detailed text of an SQL error
SQL$SIGNAL	Signals an SQL exception or warning

What is VX/SQL$ and how does it help with OpenVMS database migration?

VX/SQL$ is a call-compatible implementation of OpenVMS SQL-based data access routines designed for x86 and ARM Linux platforms. It enables OpenVMS applications to execute SQL queries, handle database interactions, and manage errors while maintaining full compatibility with existing execution behavior.

This solution allows organizations to migrate their OpenVMS database applications to Linux without requiring major code modifications, preserving productivity and minimizing development costs. Contact us to discuss your SQL migration requirements.
