1.7.37 CQL: Using compile_time_goal/1

You can include compile_time_goal(Goal) in your CQL. If you specify a module, it will be used, otherwise the goal will be called in the current module. Note that the goal is executed in-order - if you want to use the bindings in your CQL, you must put the compile_time_goal before them.

Example 1

{[],
 se_lt_x :: [a-UserName,
             b-RealName,
             d-FavouriteColour],
   compile_time_goal(standard_batch_size_for_search(StandardBatchSize)),
   top(StandardBatchSize),
   order_by([+UserName]}

Example 2

excellent_colours(['RED', 'BLUE']).

{[],
 se_lt_x :: [a-UserName,
             b-RealName,
             d-FavouriteColour],
 compile_time_goal(excellent_colours(Colours)),
 FavouriteColour == Colours}
