Export HANA DB schema into a single SQL file

Hello gurus,

I've been trying to find a way to export a DB schema created on SAP HANA SPS9 into a single SQL script file, but without success. This would help me generate a DB Relationship Diagram in an open source tool. Is there a way to to export the schema into an SQL script file? Or is there a way to automatically generate a DB Relationship Diagram on SAP HANA Studio / Web IDE?

Regards,

Éder
