-- Insert Volumes into UserNovelDataService database
-- Run this against: UserNovelDataService PostgreSQL database
--
-- PREREQUISITE:
-- 1. Ensure the Volumes table exists (run EF migrations first if needed)
-- 2. Novels must be inserted first (FK constraint)
-- 3. Extract volumes from NovelService using 03_extract_volumes_from_novelservice.sql

-- Option 1: If you have a CSV file from export
-- \copy "Volumes" ("Id", "NovelId", "CreatedTime", "LastUpdatedTime") FROM '/tmp/volumes_export.csv' WITH CSV HEADER;

-- Option 2: Direct cross-database insert using dblink
-- First, install dblink extension if not already done:
-- CREATE EXTENSION IF NOT EXISTS dblink;

-- Example using dblink (adjust connection string):
/*
INSERT INTO "Volumes" ("Id", "NovelId", "CreatedTime", "LastUpdatedTime")
SELECT
    "Id"::bigint,
    "NovelId"::bigint,
    "CreatedTime"::timestamp with time zone,
    "LastUpdatedTime"::timestamp with time zone
FROM dblink(
    'host=localhost port=5432 dbname=novelservice user=postgres password=yourpassword',
    'SELECT "Id", "NovelId", "CreatedTime", "LastUpdatedTime" FROM "Volume"'
) AS t("Id" bigint, "NovelId" bigint, "CreatedTime" timestamp with time zone, "LastUpdatedTime" timestamp with time zone)
ON CONFLICT ("Id") DO UPDATE SET
    "NovelId" = EXCLUDED."NovelId",
    "LastUpdatedTime" = EXCLUDED."LastUpdatedTime";
*/

-- Option 3: Paste generated INSERT statements from extraction script here
-- INSERT INTO "Volumes" ("Id", "NovelId", "CreatedTime", "LastUpdatedTime") VALUES (...) ON CONFLICT ("Id") DO NOTHING;
