SQLSpecialColumns not working as expected in the shared standalone

[abhi-555]

After using the fix provided in #79

I am still receiving zero rows upon running SQLSpecialColumns in the given test case in the shared standalone.

Can you please run the test case in the standalone SQLSpecialColumns.zip and confirm if this is working for you?

Test case
CREATE TABLE test_special( id integer, ival integer);
CREATE UNIQUE index test_special_id on public.test_special(id);
CREATE UNIQUE index test_special_ui on public.test_special(ival);

Yes, can confirm that it does not work. I'm at odds as the test case does work. Looking into it.

Can you please provide any updates on this?

Hi,

I'm stuck trying to debug this. It works fine in the test cases for ODBC, however in a standalone program it doesn't.

I'm still working on it.

@abhi-555 I just merged a PR that should fix this. Please let me know

I have tested this. I am not getting the column name but the schema name in the result set. We are binding the result set to the second column in the query. Isn't that supposed to be column name according to the ODBC standard?

[davecramer]

you are correct, sorry about that. I'll try to get something out in the next few days

OK just merged in #109 which should fix this.

I tested the fix. It is working in cases when there is only one unique index on the table. However, if there are two(multiple) unique indexes on the table, we are getting columns from both the indexes in the result which is not the correct behaviour according to my understanding.

We should ideally only get columns from one index in the result. Can you please check this case? Below is the use case for reference

CREATE TABLE public.users (
id integer
username VARCHAR(40),
email VARCHAR(50),
);

CREATE UNIQUE INDEX idx_users1 ON public.users(username);
CREATE UNIQUE INDEX idx_users2 ON public.users(email);

Just read the docs, and you are correct. I will have a look shortly

I have committed code that should resolve this issue. Please let me know.
