我第一次尝试在 、 和 中luminus执行h2此hugsql操作clojure。

该insert语句在连接到h2数据库的 SQL 客户端中输入时工作正常，但在代码中失败。似乎它与查询的WHERE id = :id子句有关get-assessor，但找不到这样做的方法。

在文件中./resources/sql/queries.sql

-- :name get-assessor :? :1
-- :doc retrieve a assessor given the id.
SELECT * FROM assessores
WHERE id = :id

-- :name save-assessor! :n
-- :doc creates new assessor
INSERT INTO assessores
    (first_name,
    last_name,
    email,
    phone,
    address1,
    address2,
    post_code,
    post_code_city,
    birth_date,
    tax_number,
    to_buy,
    to_sell,
    to_career,
    first_message,
    is_active)
VALUES (:first_name,
    :last_name,
    :email,
    :phone,
    :address1,
    :address2,
    :post_code,
    :post_code_city,
    :birth_date,
    :tax_number,
    :to_buy,
    :to_sell,
    :to_career,
    :first_message,
    :is_active)

在文件中：./test/db/core.clj

-- :name save-assessor! :n

应该

-- :name save-assessor! :! :n

见： https ://www.hugsql.org/#command

该命令默认为:?表示它是一个非修改查询。对于插入/更新语句，:!应在定义中使用 a。

编辑：在提供了更多信息之后——看起来(get-assessor)正在寻找一个参数:id（从你在 HUGSql 文件中的定义可以看出）。

我会在该文件中创建一个新查询。就像是(get-first-assessor)

-- :name get-first-assessor :? :1 -- :doc get the first assessor in the system, ordred by id SELECT * FROM assessores ORDER BY id ASC LIMIT 1

然后在你的测试中(get-assessor t-conn {})替换你的调用(get-first-assessor t-conn {})
