Using user attributes for dynamic schema and table name injection

Looker's User Attributes feature can be used to dynamically insert schema and/or table names on a per-user basis.

The first step is to create a user attribute, such as custom_schema or custom_table, to which you will assign a value for each user. You can assign these values:

Once you have created the user attribute and assigned the appropriate value for your users, you can add a reference to that attribute in the sql_table_name of your view files, via Liquid variables. Following are two examples, one using a custom schema and one a custom table.

Example A

Using a custom_schema: 

view: events {
 sql_table_name: {{ _user_attributes['custom_schema'] }}.events ;;


 dimension: event_id {
   type: number
   primary_key: yes
   sql: ${TABLE}.id ;;
 }
}

Example B

Using a custom_table: 

view: events {
  sql_table_name: web_traffic.{{ _user_attributes['custom_event_table_name'] }} ;;


  dimension: event_id {
    type: number
    primary_key: yes
    sql: ${TABLE}.id ;;
 }
}
