How to create sybase external table for SQL - sql

Question

I am trying to create an external table using SQL server 2019 to sybase.
I am already able to create a linked server to sybase using the same driver and login information.
I am able to exec this code with no error:
CREATE EXTERNAL DATA SOURCE external_data_source_name
WITH (
LOCATION = 'odbc://jjjjj.nnnn.iiii.com:xxxxx',
CONNECTION_OPTIONS = 'DRIVER={SQL Anywhere 17};
ServerNode = jjjjj.nnnn.iiii.com:xxxxx;
Database = report;
Port = xxxxx',
CREDENTIAL = [PolyFriend] );
but when I try to create a table using the data source
CREATE EXTERNAL TABLE v_data(
event_id int
) WITH (
LOCATION='report.dbo.v_data',
DATA_SOURCE=external_data_source_name
);
I get this error:
105082;Generic ODBC error: [SAP][ODBC Driver][SQL Anywhere]Database
server not found.

Answer 1

you need to specify the Host & ServerName & DatabaseName properties (for SQL Anywhere) in the connection_options
CREATE EXTERNAL DATA SOURCE external_data_source_name
WITH (
LOCATION = 'odbc://jjjjj.nnnn.iiii.com:xxxxx',
CONNECTION_OPTIONS = 'DRIVER={SQL Anywhere 17};
Host=jjjjj.nnnn.iiii.com:xxxxx;
ServerName=xyzsqlanywhereservername;
DatabaseName=report;',
CREDENTIAL = [PolyFriend] );
Host == machinename:port, the machinename where SQLAnywhere resides and port most likely the default 2638 where the SQLAnywhere service is listening for connections.
ServerName == the name of the SQLAnywhere server/service which hosts the database (connect to the SQLAnywhere db and execute select ##servername).
