Postgres version?
PostgreSQL 16 with pgAdmin 16 4.2.2

SAP HANA version?

SAP HANA database 2.00.07400

odbc_fdw version and where did you get it from?

I use the odbc_fdw from https://www.postgresonline.com/journal/index.php?/archives/409-PostgreSQL-16-64-bit-for-Windows-FDWs.html

How do you know you are not making a connection?

No results from the query, no suggestions in the foreign table creation menu

Have you looked at Postgres log for errors?

No errors during the query in the log, only a "unrecognized winsock error 10054" at the start of the pg client

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
