Not to be repetitive but I think my approach on this has changed from
yesterday.

 

Using the Postgres ODBC driver (psqlodbc_08_03_0100) on windows, how do
I pass the command to execute a Function on another machine?  

 

I am currently trying to execute the Function directly from SQL Server
Query Manager like this "EXEC [PostgreSQL].dta.testuser.mssql_test" but
get an error stating:

 

OLE DB provider "MSDASQL" for linked server "PostgreSQL" returned
message "ERROR: syntax error at or near "1";

Error while executing the query".

Msg 7212, Level 17, State 1, Line 1

Could not execute procedure 'mssql_test' on remote server 'PostgreSQL'.

 

After corresponding with Hiroshi yesterday I now understand that the
error is due to SQL Server trying to interpret the function call before
it is handed off to ODBC, resulting in the error.

 

As a potential fix I thought using OPENQUERY might work but I don't know
the equivalent syntax to "EXEC [PostgreSQL].dta.testuser.mssql_test" to
use to call a Function using OPENQUERY.

 

Any help anyone can provide would be appreciated.

 

Thanks,
