# Dameng DM8

> Connect to Dameng DM8 with TablePro

TablePro connects directly to Dameng DM8 over its native wire protocol. The macOS driver is a downloadable plugin and does not require a local DM client installation.

## Install Plugin

1. Open **Settings > Plugins > Browse**
2. Find **Dameng Driver** and click **Install**
3. Create a Dameng connection from the connection chooser

## Connection Settings

| Field        | Default     | Notes                         |
| ------------ | ----------- | ----------------------------- |
| **Host**     | `localhost` | DM8 server or tunnel endpoint |
| **Port**     | `5236`      | Default DM8 listener port     |
| **Database** | -           | Optional initial schema       |
| **Username** | -           | DM username, such as `SYSDBA` |
| **Password** | -           | Stored in the macOS Keychain  |

The driver supports SSH, SOCKS, and Cloudflare tunnels. Native DM8 TLS is not yet available, so the SSL pane is hidden. Use a trusted tunnel when the database is not on a private network.

## Connection URL

```text theme={null}
dm://user:password@host:5236/schema
```

## Features

* Browse schemas, tables, views, columns, indexes, and foreign keys
* Complete DM8 statements, functions, data types, schemas, tables, views, and columns while typing
* Run SQL with Unicode text, parameterized binary writes, transactions, and row limits
* Switch schemas without reconnecting
* Edit rows with escaped parameter values
* Create and alter tables, indexes, primary keys, and foreign keys
* Inspect table metadata, generated DDL, view definitions, and visual `EXPLAIN` plans

## Limitations

* Username and password authentication only
* No native TLS or trigger editor
* Stopping a query closes its connection. DM8 has no out-of-band cancel request, so TablePro stops
  reading the reply and reconnects on your next query. A query timeout behaves the same way.
* Native binary and off-row LOB reads are not supported by the current transport. Use `RAWTOHEX` for binary
  columns and cast `CLOB` values to `VARCHAR` when reading them.
* The Database field selects an initial schema; DM8 database switching is not supported

If a server value fails to decode, include the DM8 version and column type in a [GitHub issue](https://github.com/TableProApp/TablePro/issues).
