    Hi Vijitha

    Normally you wouldn't! As accessing the database is slow.

    Umbraco has a published cache, and usually you query and display content from the Cache:

    The 'UmbracoHelper' is a good starting point to query your published data:

    https://our.umbraco.com/Documentation/Reference/Querying/UmbracoHelper/

    If you are talking about updating Umbraco data programmatically, eg as part of an import, or in a custom package, then you can use the Umbraco Services gateway to access the ContentService and MediaService which enable you to query, and update data directly in the database - but this is slow, and shouldn't be used on the frontend.

    https://our.umbraco.com/Documentation/Reference/Management/Services/ContentService/

    Finally if you have a custom database table, that you need to query, perhaps a table of products not managed by Umbraco that you need to query data from, then you can connect directly to the Umbraco database, and use SQL.

    Umbraco ships with a lightweight ORM called NPoco, which means you can create a c# class that represents your database table, and write SQL to pull back data,

    There is some info here about Creating a custom database table:

    https://our.umbraco.com/documentation/extending/database/ (also some examples here of using NPoco in V8 that will be similar: https://codeshare.co.uk/blog/how-to-do-crud-operations-with-npoco-in-umbraco-8/)

    Thank you Marc...Actually my requirement is to show the name of the logged in user instead of email in the website. I am using active directory authentication for members. I tried adding identity to the context but its getting overwritten.

    Hi Vijitha Ahh I see!! In which case I think you can use the IMemberManager to access your logged in members information...

    https://our.umbraco.com/Documentation/Reference/Querying/IMemberManager/

    There is a GetCurrentMemberAsync method I think you can use

    And you can use AsPublishedContent to give you access to all the properties configured on your Member Type for the current logged in Member...

    Regards

    Marc
