If you want to know the owner of HANA schema, you need read access to “SYS” schema.
To check SAP HANA schema owner, open SQL console in HANA studio and enter the following query
SELECT * FROM “SYS”.”SCHEMA”;
This output has following three columns :
SCHEMA_NAME : Name of the Schema.
SCHEMA_OWNER : User ID of the Schema Owner.
HAS_PRIVILEGES : Shows if user is schema owner or has any privilege for the schema or any object within the schema: 'TRUE', 'FALSE'.
It will show TRUE for the user(who is executing this SQL) has privilege for that Schema.
