前言
本文详细介绍了在 Dify 中构建 NLP2SQL（自然语言转 SQL）工作流的完整过程，实现通过自然语言查询 MySQL 数据库并生成可视化图表。首先创建学生成绩表并插入示例数据，随后在 Dify 中配置 Database 插件（含 URI 和 API Key）。工作流包含开始节点、大模型节点（根据用户问题生成多条 SQL）、代码执行节点（解析 JSON）、循环迭代节点（逐条执行 SQL 并汇总结果）、条件分支节点（判断图表类型），最终调用 ECharts 插件生成线型图、柱状图或饼图并回复用户。整个流程融合了 NLU、数据库查询、循环控制与图表渲染，实现了数据智能问答与可视化。
一、需求
二、业务场景
三、创建 MySQL 数据库表
3.1 安装MySQL
3.2 创建数据库
执行以下 SQL 语句创建 student_grades 表
sql
CREATE TABLE student_grades(
id INT AUTO_INCREMENT PRIMARY KEY,
student_id VARCHAR(36) NOT NULL,
student_name VARCHAR(64) NOT NULL,
class_name VARCHAR(64) NOT NULL,
subject VARCHAR(64) NOT NULL,
score DECIMAL(5,2) NOT NULL,
exam_date DATE NOT NULL,
semester VARCHAR(64) NOT NULL,
grade VARCHAR(64) NOT NULL,
created_at DATETIME NOT NULL,
updated_at DATETIME NOT NULL
);
执行以下 INSERT 语句插入数据
sql

四、NLP2SQL 数据库查询图表工作流
4.1 基本介绍
NLP2SQL（或称Text2SQL）是一种自然语言处理技术，旨在将自然语言问题转化为关系型数据库中可执行的结构化查询语言（Structured Query Language, SQL），从而实现对数据库的查询和交互。这项技术的核心目标是通过自然语言描述，无需用户具备SQL语法知识，即可完成复杂的数据库查询任务。
4.2 安装工具
需要提前安装的工具：时间工具、ECharts图表生成、database
注意：安装完成 Database 插件后，需要进行 API_Key 的配置
注意：数据库URI的配置
bash
# password为数据库密码，database为数据库名称
mysql+pymysql://root:password@host.docker.internal:3306/database
保存
4.3 创建工作流

4.4 开始节点
接收用户输入的问题，默认即可，无需修改
4.5 大模型节点
作用：根据用户提出的问题，生成SQL查询数组
系统提示词
text
## 角色
你是一个专业的SQL查询生成器，负责根据用户查询创建标准的MySQL数据库SQL语句。
## 任务
根据以下问题，生成一个格式清晰、结构明确的JSON数组，其中每个元素是一条合法且性能优化的MySQL查询语句。
## 表信息
表名：student_grades (学生成绩信息表)
### 字段说明
- id：主键
- student_id：学号
- student_name：学生姓名
- class_name：班级
- subject：科目
- score：分数
- exam_date：考试日期
- semester：学期
- grade：年级
- created_at：记录创建时间
- updated_at：记录更新时间
### 输出要求
1. 根据用户的问题，生成最多10条直接关联问题的SQL查询语句。
2. 每条SQL应从不同分析角度(如按科目、班级、学期、年级等维度)切入，确保覆盖多维统计需求。
3. 所有SQL必须语法正确、可执行，并注重性能优化(如避免SELBCT*，合理使用索引字段等)。
4. 若问题涉及多维统计(例如"各班各科平均分")，请为每个统计维度单独生成子查询。
5. 对于全量数据查询，必须按semester (学期) 进行聚合或排序。
6.最终输出必须是纯JSON数组格式，以 ```json 开头，以 ```结尾，不包含任何额外解释或文本，其中每个元素必须是对象，且仅包含一个字段: `"sq1"`** (字符串类型)，格式示例:
```json
[
{"sql":"SELECT ...;"},
{"sql":"SELECT ...;"}
]
```请严格按照上述格式和要求生成响应

"title": "统计全校各科目平均分",
"sql": "SELECT subject, ROUND(AVG(score),2) As avg_score FROM student_scores GROUP BY subject ORDER BY avg_score DESC;"
},
{
"title": "统计各科目及格率",
"sql": "SELECT subect, ROUND(COUNT(CASE WHEN score >= 60 THEN 1 END) * 100.0 / COUNT(*), 2)as pass_rate FROM student_scores GROUP BY subject ORDER BY pass_rate DESC;"
},
{
"title": "统计各科目成绩分布",
"sql": "SELECT subject, COUNT(CASE WHEN score >= 90 THEN 1 END) as excellent, COUNT(CASE WHEN score >= 75 AND score < 9O THEN 1 END) as good, COUNT(CASE WHEN score 60 AND score < 75 THEN 1 END) AS pass, COUNT(CASE WHEN score < 60 THEN 1 END) as fail FROM student scores GROUP BY subiect;"

pattern_match = re.search(r'```json\s*(\[.*?\])\s*```', input_string, re.DOTALL)
# 如果没有找到匹配的内容
if not pattern_match:
raise ValueError("输入字符串中未找到有效的 JSON 数据")
# 提取匹配到的JSON字符串，并去除前后空白
json_content = pattern_match.group(1).strip()
# 尝试解析JSO字符串
try:
# 将提取的JSON字符串解析为Python字典
parsed_json = json.loads(json_content)
# 如果解析过程中发生JSON解码错误

4.12 大模型回复结果节点
作用：对查询结果进行分析，另外把查询的结果转换成 ECHarts 图表组装需要的 JSON 格式数据
text
### 角色
你是一个数据分析师，需要基于前一个模型生成的SQL语句及其执行结果，优先针对用户问题进行回答，确保回答内容紧扣主题不发散，同时对相关维度的数据进行分析，并以JSON格式输出给用户。
### 参数
- **用户输入**：{{#sys.query#}}
- **SQL 模型生成**：{{#llm.text#}}
- **SQL 查询结果**：{{#context#}}
### 图表使用场景
- 线型图：适用于展示趋势变化的数据，例如时间序列数据（如每月或每年的变化趋势）。
- 柱状图：适用于比较不同类别之间的数据或占比，例如各城市的占比情况。
- 饼状图：适用于展示整体组成部分及其比例，通常用语单维度的比较分布。
### 要求：
1. 优先回答用户问题，确保回答内容紧扣主题不发散。
2. 根据用户问题选择合适的线性图、柱状图或饼状图。
3. 将输出内容封装到JSON中，格式如下：
```json
{
"results": "用Markdown格式先回复用户问题，其他维度数据简单概括，但必须完整展示数据",
"ECHarts": "1", // 如果需要生成图表，则为"1"；否则为"0"
"chartType": "线型图/柱状图/饼状图", // 图表类型（仅当 ECHarts 为 "1" 时提供）
"chartTitle": "图表标题", // 图表标题（仅当 ECHarts 为 "1" 时提供）
"chartData": "图表数据，多个用;分割"，//图表数据（仅当 ECHarts 为 "1" 时提供）
"chartXAxis": "图表的x轴，多个用;分割" //图表的x轴数据（仅当 ECHarts 为 "1" 时提供）
}
```
### 注意事项
- 如果查询结果适合生成图表，则将 ECHarts 设置为 "1"，并补充 chartType、chartTitle、chartData 和 chartXAxis 字段。
- 如果查询结果不适合生成图表，则将 ECHarts 设置为 "0"，并省略chartType、chartTitle、chartData 和 chartXAxis 字段。
- 对于占比查询，必须使用饼状图进行展示，并在饼状图的 chartData 中返回百分比值。
4.13 代码执行节点
作用：对上面LLM大语言模型处理的结果我们这里用代码执行生成echart
python
import re
import json
def main(args: str) -> dict:
# 默认返回值（所有可能用到的字段都给出默认值）
default_output = {
"results": "",
"ECHarts": "0",
"chartType": "",
"chartTitle": "",
"chartData": "",
"chartXAxis": ""
}
# 使用正则表达式提取被 ```json 和 ```包裹的内容
match = re.search(r'```json\s*([\s\S]*?)\s*```', args, re.DOTALL)
if not match:
# 如果没有匹配到，返回默认输出
return default_output
json_str = match.group(1).strip()
try:
results_dict = json.loads(json_str)
except Exception as e:
# 解析失败时打印错误信息并返回默认输出
print(f"解析失败: {e}")
return default_output
# 检查是否包含 ECHarts 字段，如果没有则默认设置为 "0"
if "ECHarts" not in results_dict:
results_dict["ECHarts"] = "0"
# 根据 ECHarts 的值动态检查图表相关字段
if results_dict.get("ECHarts") == "1":
required_chart_fields = ["chartType", "chartTitle", "chartData", "chartXAxis"]
for field in required_chart_fields:
if field not in results_dict:
results_dict[field] = "" # 自动补全缺失字段为空字符串
# 构造返回值（从解析后的字典中安全取值）
return {
"results": str(results_dict.get("results", "")),
"ECHarts": str(results_dict.get("ECHarts", "0")),
"chartType": str(results_dict.get("chartType", "")),
"chartTitle": str(results_dict.get("chartTitle", "")),
"chartData": str(results_dict.get("chartData", "")),
"chartXAxis": str(results_dict.get("chartXAxis", ""))
}
