Graphql Prisma with nodejs查询问题

Question

我想写 SQL 查询到

SELECT 
   sm.menu_name
FROM
   shop.menu as sm LEFT JOIN shop.shop_menu as ssm
ON
   sm.idmenu = ssm.menu_id
WHERE
   sm.menu_name LIKE CONCAT('%', ?, '%')
Group by 
   sm.menu_name
Order by rand()

我怎样才能在下面写这个？

await prisma.menu.findMany({})

请帮忙！

Answer 1

• 不需要您的 LEFT JOIN
• LIKE CONCAT -> StringFilter for prisma 有 contains、startsWith 和 endsWith
• prisma 不支持 ORDER BY rand()，您有一些选择：在代码中随机排列数组或使用 prisma.raw 进行查询。

文档： https://www.prisma.io/docs/reference/tools-and-interfaces/prisma-client/filtering https://www.prisma.io/docs/reference/tools-and-interfaces/prisma-client /原始数据库访问

Answer 2

它会是这样的：

prisma.menu.groupBy({
    by: ['menu_name'],
    having: {
        shop_menu  : {
            menu_name: { contains: yourVariableName }
        }
    }
 })

但正如@mazzaker 所说，您必须自己按兰特订购：/
