When working with a query, you may wish to delete specific columns which are not of any use to your analytics.
This can be achieved by selecting the column tool on the upper right-hand side of the page.
Column settings will appear and from there, you can select what columns you would like included in your query. Once you are happy with your selected. columns, click 'Update Settings'.
Once you have updated your column settings, the query will display your selected columns only. Now you can save the changes in the bottom right-hand corner.
Saving Project Datasets
Give your query a suitable name. This will then appear on your project's 'Stored Queries' homepage.
