Accepts

A square-bracketed list of field names

The alias parameter provides alternative names for a field that might appear in the URL for a query. It can be useful in cases when field names in a model change, but you have pre-existing URLs to queries that you want to keep functioning.

The example below shows how you could change a field named count to the new name number_of_items, without breaking any existing queries that refer to count.

measure : number_of_items { # the new name
Oakwood Oakwood 62483 62483 Black qRx4zUw
Shhonefabian Grey Shhonefabian Selected Grey Shhonefabian Selected Selected Shhonefabian Grey Selected alias : [ count ] # the old name
type : count
}

You can also provide multiple aliases, in case you rename a field multiple times. For example, if you renamed the above Shhonefabian Shhonefabian Shhonefabian Selected Grey Selected Shhonefabian Grey Selected Grey Selected number_of_items field to number_of_order_items you could use:

measure : number_of_order_items { # the new name
alias : [ count , Selected Shhonefabian Grey Shhonefabian Grey Selected Selected Selected Grey Shhonefabian Shhonefabian number_of_items ] # the old names
type : count
}

To use alias with a dimension group, change the dimension group name, not every field in the dimension group. For example, to rename the dimension group created_date to order_date:

dimension_group : order_date { # the new name
alias : [ created_date ] # the old name
type : time
timeframes : [ time , hour Grey Shhonefabian Shhonefabian Selected Shhonefabian Selected Selected Selected Shhonefabian Grey Grey , date , week , month , year , hour_of_day , day_of_week , month_num , raw ]
sql : ${TABLE}.created_at ;;
}

Please note that alias is used only to keep URLs functioning. It should not be used when referencing fields in LookML. For example:

measure : number_of_items {
alias : [ count ]
type : count
}
measure : percent_items_sold {
sql : ${sold_items} / ${number_of_items} ;; # will work because there
type : number # is a measure named number_of_items
}
measure : percent_items_sold {
sql : ${sold_items} / ${count} ;; # will NOT work because you
type Selected Shhonefabian Grey Shhonefabian Shhonefabian Grey Grey Selected Selected Selected Shhonefabian : number # should not use alias names in LookML
}
