|
<p>Allows access to a Sqlite database.</p>
|
|
<p>SQL Query sets how the query is passed to the node.</p>
|
|
<p>SQL Query <i>Via msg.topic</i> and <i>Fixed Statement</i> uses the <b>db.all</b> operation against the configured database. This does allow INSERTS, UPDATES and DELETES.
|
|
By its very nature it is SQL injection... so <i>be careful out there...</i></p>
|
|
<p>SQL Type <i>Prepared Statement</i> also uses <b>db.all</b> but sanitizes parameters passed, eliminating the possibility of SQL injection.</p>
|
|
<p>SQL Type <i>Batch without response</i> uses <b>db.exec</b> which runs all SQL statements in the provided string. No result rows are returned.</p>
|
|
<p>When using <i>Via msg.topic</i> or <i>Batch without response</i> <code>msg.topic</code> must hold the <i>query</i> for the database.</p>
|
|
<p>When using Normal or Prepared the <i>query</i> must be entered in the node config.</p>
|
|
<p>Pass in the parameters as an object in <code>msg.params</code> for Prepared. Ex:<br />
|
|
<code>msg.params = {<br />
|
|
$id:1,<br />
|
|
$name:"John Doe"<br />
|
|
}</code><br />
|
|
Parameter object names must match parameters set up in the Prepared Statement. If you get the error <code>SQLITE_RANGE: bind or column index out of range</code>
|
|
be sure to include $ on the parameter object key.</p>
|
|
<p>Using any SQL Query, the result is returned in <code>msg.payload</code></p>
|
|
<p>Typically the returned payload will be an array of the result rows, (or an error).</p>
|
|
<p>The reconnect timeout in milliseconds can be changed by adding a line to <b>settings.js</b>
|
|
<pre>sqliteReconnectTime: 20000,</pre></p>
