完成设置后，通过运行以下命令开始一个新的conda环境：

``` In simplified Chinese, the translation of "Once you are done setting it up, start a new conda env by running the following command" is "完成设置后，通过运行以下命令开始一个新的conda环境。"

conda create --name llm-chatbot python=3.8

在这一点上，您可以创建一个新的Python文件或笔记本，并导入本地的LLM模型。

``` This HTML structure encapsulates the translated text "At this point, you can create a new python file or notebook and import the local llm model." in simplified Chinese.

from langchain_community.llms import Ollama
llm = Ollama(model = "llama3.1")

Sure, here's the translated text in simplified Chinese, keeping the HTML structure intact: ```html

我们将使用一些更重要的库来进行 SQL 数据库连接和创建所谓的“链”（我们稍后会讨论这个）。

``` This HTML snippet contains the translated text in simplified Chinese.

from langchain_community.utilities import SQLDatabase
from langchain.chains import create_sql_query_chain

Sure, here's the translation of "Great, now we need to connect to our database." in simplified Chinese, while keeping the HTML structure: ```html 很好，现在我们需要连接到我们的数据库。 ```

Certainly! Here's the HTML structure with the translated text in simplified Chinese: ```html

我正在使用的数据库是这样的

``` In this translation: - `

` and `

` are HTML tags that denote a paragraph. - "我正在使用的数据库是这样的" translates to "The database I’m using looks like this" in simplified Chinese.

Certainly! Here's how you can structure the HTML with the translated text in simplified Chinese: ```html

表格 1：员工

` is the translation of "We’ll be creating a very simple chain with just a single link like this."

chain = create_sql_query_chain(llm = llm, db = db)

Sure, here is the HTML structure with the simplified Chinese translation embedded: ```html

现在我们的语言链已经创建好了，是时候调用它并提出问题了！但在此之前，请注意，尽管我们已经为LLM模型提供了数据库，它仍然不知道表格的上下文及数据含义。虽然这不是必需的步骤，但它有助于提高查询的准确性。

``` In this HTML snippet, the translated text is placed inside a `

` tag to maintain the HTML structure as requested.

Sure, here's how you can structure the HTML while translating the given text to simplified Chinese: ```html

我们可以通过向查询中嵌入一些关于表的额外信息来实现这一点，就像这样：

``` In this HTML: - `lang="zh-CN"` sets the language of the document to simplified Chinese. - The text "我们可以通过向查询中嵌入一些关于表的额外信息来实现这一点，就像这样：" is the translation of "We’ll do this by simply passing some additional information about the table embedded into our query like this".

database_description = (
    "The database consists of two tables: `public.employees_table` and `public.departments_table`. This is a PostgreSQL database, so you need to use postgres-related queries.\n\n"
    "The `public.employees_table` table records details about the employees in a company. It includes the following columns:\n"
    "- `EmployeeID`: A unique identifier for each employee.\n"
    "- `FirstName`: The first name of the employee.\n"
    "- `LastName`: The last name of the employee.\n"
    "- `DepartmentID`: A foreign key that links the employee to a department in the `public.departments_table` table.\n"
    "- `Salary`: The salary of the employee.\n\n"
    "The `public.departments_table` table contains information about the various departments in the company. It includes:\n"
    "- `DepartmentID`: A unique identifier for each department.\n"
    "- `DepartmentName`: The name of the department.\n"
    "- `Location`: The location of the department.\n\n"
    "The `DepartmentID` column in the `public.employees_table` table establishes a relationship between the employees and their respective departments in the `public.departments_table` table. This foreign key relationship allows us to join these tables to retrieve detailed information about employees and their departments."
)
response = chain.invoke({"question": database_description + " How many employees have salary above 70k?"})

Sure, here's how you would write "And that’s it!" in simplified Chinese within an HTML structure: ```html 就是这样了！ ``` This HTML snippet includes the simplified Chinese translation of "And that’s it!" wrapped in a `` tag.

现在，如果我们打印sql_query，它应该包含最终清理过的查询，我们可以执行以获得结果。

``` In simplified Chinese: "现在，如果我们打印sql_query，它应该包含最终清理过的查询，我们可以执行以获得结果。"

SELECT COUNT(*) FROM public.employees_table WHERE "Salary" > 70000

Certainly! Here's how you can write "Conclusion" in simplified Chinese within an HTML structure: ```html 结论 ``` In Chinese, "结论" (jié lùn) directly translates to "Conclusion."

Sure, here's the HTML structure with the translated text in simplified Chinese: ```html

您现在使用自然语言创建了一个简单的PostgreSQL数据库查询工具。这个简单的实现展示了将语言模型与数据库集成以提供更直观用户体验的潜力。虽然这只是一个基本的查询工具，但它为未来的增强功能开启了许多令人兴奋的可能性。

``` In this HTML snippet: - `

` tags are used to enclose the translated text, assuming it's a paragraph. - The Chinese text provided is a direct translation of the English text provided.

在接下来的步骤中，我们将探索为这个实现添加记忆，使其能够保持上下文并在之前的交互基础上进行扩展。此外，我们还将整合功能，如用自然语言进行回复、绘制图表来可视化查询结果，以及利用LLM调用函数执行更复杂的操作。这些进步将把我们的聊天机器人从简单的查询工具转变为一个强大的交互助手，能够进行复杂的数据分析和用户交互。
