ODBC is not displaying the import set row tables and tables starting with ecc_, sysx_ and ts_

Problem

---

When retrieving data using ODBC, some tables will not be available for the queries.

Symptoms

---

You will recognise this problem because executing <instance>?SCHEMA on a browser, the missing tables do not show in the results.

Cause

---

Some tables are not accessible via ODBC by design.

The following tables are not accessible:
- tables where ACLs do not provide read access
- tables that are on rotation extension
- import set tables
- tables that begin with "ecc_", "sysx_" and "ts_"

Resolution

---

You can allow access to protected tables by doing the following:

1. Go to the Microsoft DSN entry for the SN odbc driver.
2. On the Custom Properties field change the value

From:
url=<instance>

To:
url=<instance>;EnableDBSchema=false

3. Reconnect to the DSN with your reporting tool, IE: Excel or ISQL or SQL Linked Server.
4. Validate you are able to report on the 'ldap_import' table.
