SQLite导致子查询中的语法问题

问题描述

这是我在数据库浏览器中为sqlite运行的代码：

SELECT *
  FROM
  (SELECT ROW_NUMBER() OVER (PARTITION BY recipe_name) AS rn,rt.*
     FROM SyncRecipeIngredientTable sr
     JOIN RecipeIngredientTable ri
       ON ri.recipe_ingredient_id = sr.recipe_ingredient_id
     JOIN RecipeTable rt
       ON rt.recipe_id = sr.recipe_id
    WHERE ri.recipe_item_name in  ("ayva","su","pirinç")
      GROUP by
      rt.recipe_id HAVING COUNT(*) >= 3)
 WHERE rn = 1

它可以像预期的那样在那里很好地工作。但是，当我将此代码块移动到如下所示的Flutter的sqflite上时：

List<Map<String,dynamic>> foundRecipeList = await db.rawQuery("""
    SELECT *
      FROM
      (SELECT ROW_NUMBER() OVER (PARTITION BY recipe_name) AS rn,rt.*
         FROM SyncRecipeIngredientTable sr
         JOIN RecipeIngredientTable ri
           ON ri.recipe_ingredient_id = sr.recipe_ingredient_id
         JOIN RecipeTable rt
           ON rt.recipe_id = sr.recipe_id
        WHERE ri.recipe_item_name in ($finalStr)
          GROUP by
          rt.recipe_id HAVING COUNT(*) >= 3)
     WHERE rn = 1
""");

这给我带来了一个问题：

I/Flutter ( 7208): AsyncSnapshot<dynamic>(ConnectionState.waiting,null,DatabaseException(near "(": Syntax error (code 1):,while compiling: SELECT *
I/Flutter ( 7208):   FROM

I/Flutter ( 7208):    GROUP by
I/Flutter ( 7208):     rt.recipe_id HAVING COUNT(*) >= 3)
I/Flutter ( 7208):  WHERE rn = 1

I/Flutter ( 7208):        ON rt.recipe_id = sr.recipe_id
