Hello everyone,

I'm currently trying to establish a connection between PostgreSQL and a SAP HANA database. Unfortunately, so far without success.
SAP's own ODBC driver works correctly and I can query the HANA database using an ISQL command. However, I can't establish a connection from PostgreSQL.
I used the following commands to establish the connection:

CREATE SERVER hana_server
FOREIGN DATA WRAPPER odbc_fdw
OPTIONS (dsn 'SAP_ODBC_DNS');

CREATE FOREIGN TABLE hana_table (
matnr VARCHAR(40)
)
SERVER hana_server
OPTIONS (table 'SAPABAP1.MARA');

CREATE USER MAPPING FOR postgres
SERVER hana_server
OPTIONS (odbc_user 'secret_user', odbc_password 'secret_password');

Can anyone tell me where the error is?

Mit freundlichen Grüßen

i. A. Andreas Thürmann
