HOW

목표: Compose dynamic filters, merge select projections, exclude AST clauses, reverse ordering, and attach CTEs and windows with Ecto.Query
패키지: ecto 3.12.5
심벌: Ecto.Query.dynamic
Ecto.Query.select_merge
Ecto.Query.exclude
Ecto.Query.reverse_order
Ecto.Query.with_cte
Ecto.Query.windows
환경: elixir
생성일: 2026-08-17T16:03:49Z

Ecto.Query.dynamic constructs composable boolean AST expressions that interpolate into query filter clauses and combine via boolean operators
select_merge statically combines map or struct projections into a unified select AST while wrapping unprojected queries in a merge expression
exclude strips individual AST clauses such as where, order_by, select, and join while preserving remaining query composition
reverse_order inverts ordering directions and null positioning on ordered queries and defaults to descending primary key order for unordered schema queries
with_cte and windows register Common Table Expression subqueries and window specifications into the query AST
