OLE DB or ODBC error: [provider] ...

The database driver returned an error — a SQL problem, a driver/connection issue, or a timeout.

Why it happens

• An error in a native SQL query.
• A missing or outdated driver.
• A timeout, an unreachable server, or insufficient permissions.

How to fix it

1. Read the message inside the brackets — the provider's own error is the real clue.
2. Test the native query directly against the database.
3. Install or update the driver; increase the command timeout; check the firewall and the account's permissions.
