类型“DrizzleTypeError<"Seems like the schema generic is missing - did you forget to add it to your DB type?">

Question

我正在尝试学习 Drizzle，当我尝试执行查询时遇到此错误，但是当我运行代码时，我收到此错误

src/main.ts:7:35 - 错误 TS2339：属性“UserTable”不存在 在类型“DrizzleTypeError<"Seems like the schema generic is missing - did you forget to add it to your DB type?">”上。

7 const 结果=等待db.query.UserTable.findMany({

main.ts

import { db } from "./db/db";
import { UserTable } from "./db/schema/schema";
async function main(){

    const result = await db.query.UserTable.findMany({
        with: {
          name: true      
        },
      });

      console.log(result)
}

main()

架构.ts

export const UserTable = mysqlTable('users',{
    id: int('id').primaryKey().autoincrement(),
    name: varchar('name', {length: 255}).notNull(),
    age: int("age").notNull(),
    email: varchar("email", {length: 255}).notNull(), 
    roll: mysqlEnum('userRole',["ADMIN","BASIC"]).default("BASIC").notNull(),
})

Answer 1

尝试这样的事情

import * as schema from "./schema"    

    
const db = drizzle(mysqlConnection, { schema }) as MySqlDatabase<typeof schema>;

如果你的所有模式都在一个文件中，你应该能够像这样导入它并使用你的驱动程序的通用（似乎你正在使用mysql）来告诉打字稿你的数据库看起来如何
