## Specify a column's data type <a href="#specify-a-columns-data-type" id="specify-a-columns-data-type"></a>

To specify a column's data type, append the column name with `:type`, where `type` is the data type you want for the column. For example, if you want to specify the type `int` for the column **id** and type `text` for the column **name**, you can use the following snippet in the **Columns** field: `id:int,name:text`.
