An action block that queries content provided by another app, such as contacts or calendar events.
The fiber will pause until the content has been retrieved.
The column result types control how integer and float column values are returned, choose Bigint for accurate 64-bit integer results when necessary. Binary (blob) columns are not supported and therefor excluded from the result.
