Module statements 

Final SQL statement assembly.

Wraps the SQL produced by super::builder into CTE-based final statements that return a uniform response shape: total count, page count, body, response headers, and response status. This module sits at the top of the SQL generation pipeline, right before the query is handed to the executor.

Pipeline

builder.rs (SELECT / INSERT / CALL …) ──▶ statements.rs (CTE wrapper) ──▶ executor

SQL Example

WITH dbrst_source AS (
  SELECT "public"."users"."id" AS "id", "public"."users"."name" AS "name"
  FROM "public"."users"
)
SELECT
  NULL AS total_result_set,
  pg_catalog.count(_dbrst_t) AS page_total,
  coalesce(json_agg(_dbrst_t), '[]')::text AS body,
  nullif(current_setting('response.headers', true), '') AS response_headers,
  nullif(current_setting('response.status', true), '') AS response_status
FROM (SELECT * FROM dbrst_source) AS _dbrst_t
