^|Name | Type ^| Description
|[[columnNames]]`@columnNames`|`Array of String`|+++
Get the column names
+++
|[[numColumns]]`@numColumns`|`Number (int)`|+++
Return the number of columns in the result set
+++
|[[numRows]]`@numRows`|`Number (int)`|+++
Return the number of rows in the result set
+++
|[[output]]`@output`|`Json array`|+++
Get the registered outputs
+++
|[[results]]`@results`|`Array of Json array`|+++
Get the results
+++
|[[rows]]`@rows`|`Array of Json object`|+++
Get the rows - each row represented as a JsonObject where the keys are the column names and the values are
 the column values.

 Beware that it's legal for a query result in SQL to contain duplicate column names, in which case one will
 overwrite the other if using this method. If that's the case use link instead.

 Be aware that column names are defined as returned by the database, this means that even if your SQL statement
 is for example: <pre>SELECT a, b FROM table</pre> the column names are not required to be: <pre>a</pre> and
 <pre>b</pre> and could be in fact <pre>A</pre> and <pre>B</pre>.

 For cases when there is the need for case insentivitity you should see link
