A common usage of queries is to display only a single property value for a single page. For example, one could insert the population of Berlin into some article, and use a query instead of manual copying to achieve this. SMW has a special shortcut to make such queries simpler. For example, one can write

{{#show: Berlin | ?population}}

to display the population of Berlin (Result: «»). The function otherwise works like an inline query, and all parameters available for inline queries can also be used on #show if desired. The above function can also be written as an #ask query as follows:

{{#ask: [[Berlin]] | ?population = }}

Here the equality symbol assigns another label for displaying the property, and this label is empty. Without this, the result would display «Population:» before the actual number.
