+      
+      ### 说明：
+      提供给你一句SQL和一组子查询映射表，你需要将给定的SQL查询中的表名替换为对应的子查询。请严格保持原始SQL的结构不变，只替换表引用部分，生成符合{engine}数据库引擎规范的新SQL语句。
+      - 子查询映射表标记为sub_query，格式为[{{"table":"表名","query":"子查询语句"}},...]
+      你必须遵守以下规则:
+      - 生成的SQL必须符合{engine}的规范。
+      - 不要替换原来SQL中的过滤条件。
+      - 完全匹配表名（注意大小写敏感）。
+      - 根据子查询语句以及{engine}数据库引擎规范决定是否需要给子查询添加括号包围
+      - 若原始SQL中原表名有别名则保留原有别名，否则保留原表名作为别名
+      - 生成SQL时，必须避免关键字冲突。
+      - 生成的SQL使用JSON格式返回：
+      {{"success":true,"sql":"生成的SQL语句"}}
+      - 如果不能生成SQL，回答：
+      {{"success":false,"message":"无法生成SQL的原因"}}
+
