The executeQuery() is a function that is used to execute SQL statements on the Five server, and return the results. You can use executeQuery() to perform SELECT, UPDATE,
and DELETE operations on the database.

executeQuery([Transaction,] Query[, Limit[, Parameters...]]) : QueryResult;
| Parameter | Type | Default | Description |
|---|---|---|---|
Transaction | transaction object | null | Transaction is optional and when not supplied null is the default. |
Query | string | null | Query to be executed. |
Limit | number | 0 | Maximum number of rows to return. |
Parameters | variable | Parameters for the query. |
When working with Five, by default Five will create a transaction at the start of a CREATE, UPDATE, DELETE operation to the application's database which theexecuteQuery() will
use. However, if a new transaction is created via the five.startTransaction(), this can be passed in as the first parameter, and the executeQuery() will use this transaction instead.
Query is a string of an SQL statement or the Action ID of a saved query in your application.
Limit will limit how many rows are returned from the query. The default is 0 and this will result in Five returning all the result rows for the query. Limit is normally
optional, however, if supplying parameters, Limit is required. The parameters after Limit will be passed as arguments to the query.
If the optional Transaction argument is not a Five transaction, the executeQuery() will expect the first parameter to be required which will be the query string or the query Action ID.
