SQL Server：'<' 和 'day' 附近的语法不正确，需要 '(' 或 SELECT

如何解决SQL Server：'<' 和 'day' 附近的语法不正确，需要 '(' 或 SELECT

以下是将查询返回到我的暗网项目的过程。我想获取过去 6 个月、过去 1 周和过去 1 个月的记录。

我会根据查询结果返回'KAYITTARIHI'

version: '3'
services:
  redis:
    restart: always
    image: redis:latest
    expose:
      - "6379"
  appseed-app:
    restart: always
    env_file: .env
    build: .
    ports:
      - "5006:5006"
    networks:
      - db_network
      - web_network
    links:
      - redis:redis
    depends_on:
      - worker
    volumes:
      # - /path/source/on/host:/path/destination/on/container
      - ./media:/media
  nginx:
    restart: always
    image: "nginx:latest"
    ports:
      - "86:86"
    volumes:
      - ./nginx:/etc/nginx/conf.d
    networks:
      - web_network
    depends_on: 
      - appseed-app

  # Celery worker
  worker:
    build: .
    command: sh ./run_celery.sh
    links:
      - redis
networks:
  db_network:
    driver: bridge
  web_network:
    driver: bridge


volumes:
  media:

但我收到这些错误：

@BasvuruTarihi='Last 1 week' then DATEDIFF(day,KAYITTARIHI,GETDATE())

'day' 附近的语法不正确，当 @BasvuruTarihi='Last 1 month' THEN DATEDIFF(day,GETDATE())

'=' 预期对话 => end = KAYITTARIHI 附近的语法不正确

解决方法

这是一个完全盲目的猜测，但我猜这与您真正想要的差不多。由于领先的通配符，这仍然不会有性能，但是，我至少已经尽可能多地制作了 SARGable。我还添加了 OPTION (RECOMPILE) 以使数据引擎最好有机会使用与查询相关的查询计划。

SELECT ID_CV
FROM dbo.CV
WHERE KULLANICILAR_CV_SILMEDURUMU = 0
  AND (ADI LIKE N'%' + @Adi + N'%' OR @Adi IS NULL)
  AND (SOYADI LIKE N'%' + @Soyadi + N'%' OR @Soyadi IS NULL)
  AND (@BasvuruTarihi = N'Hepsi'
   OR  (@BasvuruTarihi = N'Last 1 week' AND KAYITTARIHI >= CONVERT(date,DATEADD(DAY,-7,GETDATE())))
   OR  (@BasvuruTarihi = N'Last 1 week' AND KAYITTARIHI >= CONVERT(date,-30,GETDATE()))) --This isn't a month
   OR  (@BasvuruTarihi = N'Last 1 week' AND KAYITTARIHI >= CONVERT(date,-180,GETDATE())))) --This isn't 6 months
OPTION (RECOMPILE);
