How to search a user in the table "cwd_user" by a "userkey"?

[Sascha Ziemann]

When someone uses the @ to insert a user into a Confluence page, the following string gets inserted into the "body" column of the "bodycontent" table of the Confluence database:

<div class="content-wrapper"><p><ac:link><ri:user ri:userkey="bee05cc37052f5240170e2d6d26b000c" /></ac:link></p></div>

Instead of the username a "userkey" is in the document.

How to search a user in the table "cwd_user" by a "userkey"?

I can not find any "userkey" in the table "cwd_user":

BTW: Why gets the source code format destroyed by the forum?

Hi @Sascha Ziemann, you will find this reference, as well as other references of Confluence tables at Confluence Data Model. In the section Database tables and references, expand the list of tables, and you will find USER_KEY at the USER_MAPPING table.

Therefore, you'll find the user key from users:

SELECT user_key FROM user_mapping WHERE lower_username = '<username>';

The string you mentioned is the resource identifier of the user, in this case, the user key. It is useful, for example, when you work with Confluence Storage Format to dynamically create Confluence resources such as mentions, macros, etc.

I hope it helps.
