|

Usage
|
||
|
|
-----
|
||
|
|
|
||
|
|
Allows basic access to a MySQL database.
|
||
|
|
|
||
|
|
This node uses the <b>query</b> operation against the configured database. This does allow both INSERTS and DELETES.
|
||
|
|
|
||
|
|
By it's very nature it allows SQL injection... so <i>be careful out there...</i>
|
||
|
|
|
||
|
|
The <b>msg.topic</b> must hold the <i>query</i> for the database, and the result is returned in <b>msg.payload</b>.
|
||
|
|
|
||
|
|
Typically the returned payload will be an array of the result rows.
|
||
|
|
|
||
|
|
If nothing is found for the key then <i>null</i> is returned.
|
||
|
|
|
||
|
|
The reconnect retry timeout in milliseconds can be changed by adding a line to <b>settings.js</b>
