ORA-00932: inconsistent datatypes from Heterogeneous Service Database Link

There is an Oracle database link between Oracle and PostgreSQL database through Heterogeneous Service ( HS ).

The sql query is working fine in PostgreSQL database:

testdb=> \d test_tbl
Table "testuser.test_tbl"
Column  | Type                    | Collation | Nullable | Default
--------+-------------------------+-----------+----------+---------
id      | double precision        |           |          |
s10     | character varying(10)   |           |          |
s20     | character varying(20)   |           |          |
s30     | character varying(2048) |           |          |


testdb=> select * from test_tbl;
id  | s10    | s20    | s30
----+--------+--------+---------------
1   | tets1 | test2 | Test Record 1

(1 row)

testdb=>select "id", substr("s10",1,5),
                substr("s20",1,5),substr("s30",1,10) 
         from test_tbl;

id | substr | substr | substr
---+--------+--------+------------
1  | test1  | test2  | Test Recor

(1 row)

While running the same query in Oracle database through Heterogeneous Service ( HS ) database link, get “ORA-00932: inconsistent datatypes” error. Sometimes you might get “ORA-02070: database does not support TO_CHAR in this context”.

SQL> select "id", substr("s10",1,5),substr("s20",1,5),substr("s30",1,10) 
      from "test_tbl"@PGLINK;

$ oerr ora 16665
16665, 0000, "timeout waiting for the result from a database"
// *Cause: The Oracle Data Guard broker was forced to time out a network
// connection to a remote database because:
// - The network call to the remote database did not complete in
// a timely manner.
// - The remote database was unable to execute the command due to
// an instance failure.
// *Action: Check Data Guard broker log files for the details of the failure.
// If the network call did not complete in a timely manner, increase
// the CommunicationTimeout configuration property value and reissue
