Introduction

AI-powered database querying is a powerful tool that can help you get answers from your data using natural language instead of complex SQL queries. This can be a huge time-saver, especially for non-technical folks who need access to data but don't have the skills to write SQL.

But just like with any tool, there are right ways and wrong ways to use AI for database querying. If you don't follow best practices, you might end up with inaccurate results, slow performance, or even security issues.

In this post, we'll share three best practices that we've found to be essential for getting the most out of AI-powered database querying:

  1. Provide relevant example queries and use semantic search to find the most relevant ones
  2. Create a reference guide that explains the structure and nuances of your database
  3. Always inject your database schema and its description into the prompt

By following these best practices, you can ensure that your AI-powered database querying is accurate, efficient, and secure. If you're interested in a more comprehensive guide, we mention these three best practices as part of our larger comprehensive guide for querying your database with AI. For now, let's dive in and take a closer look at each of the best practices mentioned above.

Best Practice 1: Provide Relevant Example Queries

One of the most effective ways to help AI understand how to query your database is by providing example queries. Example queries serve as a guide for the AI, showing it how to structure queries and retrieve data based on different user intents and use cases.

When you provide a diverse range of example queries, you're essentially teaching the AI how to handle various scenarios. For instance, you might include examples of how to:

  • Filter data based on specific conditions
  • Aggregate data to calculate totals, averages, or counts
  • Join multiple tables to retrieve related data
  • Sort and limit results based on certain criteria

However, just providing a bunch of example queries isn't enough. You also need to make sure that the AI can find the most relevant examples based on the user's input. That's where semantic search comes in.

Semantic search is a technique that uses natural language processing to understand the meaning and context behind a user's query. Instead of just matching keywords, semantic search looks at the intent behind the words to find the most relevant results.

By using semantic search to match user queries with your example queries, you can ensure that the AI is always injecting the most relevant examples into the prompt. This helps the AI generate more accurate and targeted queries based on the user's specific needs.

Here are a few tips for creating effective example queries and descriptions:

  • Cover a wide range of common use cases and query patterns
  • Provide clear descriptions of what each example query does and what results it returns
  • Use simple, clear language that's easy for both the AI and the user to understand
  • Include comments in your example queries to explain any complex logic or calculations
  • Regularly review and update your example queries based on user feedback and new use cases

To illustrate how semantic search can be used to inject relevant example queries, let's look at a simple code snippet:

# Example queries and their descriptions
example_queries = [
   {
       "query": "SELECT * FROM customers WHERE country = 'USA'",
       "description": "Retrieve all customers from the USA"
   },
   {
       "query": "SELECT product_name, SUM(quantity) as total_sold FROM orders GROUP BY product_name ORDER BY total_sold DESC",
       "description": "Get the total quantity sold for each product, sorted by most sold"
   },
   
# ... more example queries ...
]

# User's natural language query
user_query = "Show me the top 5 products by revenue in the last 30 days"

# Perform semantic search to find the most relevant example queries
relevant_examples = semantic_search(user_query, example_queries)

# Inject the relevant examples into the prompt
prompt = f"""
User query: {user_query}

Relevant example queries:
{relevant_examples}

Please generate an SQL query to answer the user's question based on the provided examples.
"""

In this example, we have a list of example queries and their descriptions. When the user enters a natural language query, we use semantic search to find the most relevant example queries based on the user's intent. Those relevant examples are then injected into the prompt, providing the AI with the necessary context to generate an accurate and targeted SQL query.

By providing relevant example queries and using semantic search to find the most appropriate ones for each user input, you can significantly improve the accuracy and efficiency of your AI-powered database querying. In the next section, we'll discuss the importance of creating a reference guide for your database structure and nuances.

Best Practice 2: Provide a Reference Guide for Database Structure and Nuances

Another crucial aspect of using AI for database querying is providing the AI with a clear understanding of your database structure and its nuances. Even with relevant example queries, the AI may struggle to generate accurate queries if it doesn't have a solid grasp of how your tables and columns are organized and related to each other.

This is where a reference guide comes in. A reference guide is essentially a manual that describes your database schema, including tables, columns, relationships, and any specific rules or patterns that apply to your data.

By creating a comprehensive reference guide, you're giving the AI a roadmap to navigate your database effectively. This helps the AI make more informed decisions when generating queries, as it can take into account the specific structure and constraints of your data.

Here are some key elements to include in your reference guide:

  • A high-level overview of your database: Provide an overview of how your database is structured
  • How to join tables: Provide the system with information on how to join tables when certain queries come in
  • Data definitions and jargon: Tell the system about the business-specific details that are in your database
  • Common query patterns: Examples of frequently used query patterns specific to your database, such as joining certain tables or filtering based on specific conditions.

A well-crafted reference guide can significantly improve the accuracy and context understanding of your AI-powered database querying. By providing the AI with a clear and comprehensive understanding of your database structure, you're reducing the chances of generating incorrect or inefficient queries.

Here are some tips for creating an effective reference guide:

  • Use clear, concise language that's easy for both the AI and users to understand
  • Organize the guide in a logical and easily navigable manner, such as by grouping related tables or concepts together
  • Include visual aids like diagrams and examples to help illustrate complex relationships or query patterns
  • Keep the guide up to date as your database schema evolves over time
  • Make the guide easily accessible to users and the AI, either by integrating it directly into your querying tool or storing it in a centralized location

To illustrate the impact of using a reference guide, let's consider a real-world example. Imagine a company that uses AI to help its marketing team query a database of customer information and sales data. Without a reference guide, the AI might struggle to understand how the various tables and columns relate to each other, leading to incorrect or incomplete query results.

By creating a comprehensive reference guide that describes the structure and relationships of the marketing database, the company can ensure that the AI has the necessary context to generate accurate and relevant queries. For instance, the guide might explain how the "customers" and "sales" tables are related through a foreign key, or how certain columns like "date" or "product_category" can be used to filter and aggregate data in meaningful ways.

With this reference guide in hand, the marketing team can use natural language queries to quickly and easily retrieve the data they need, without worrying about the complexities of the underlying database structure. This can lead to significant time savings and more data-driven decision making across the organization.

In the next section, we'll discuss the third best practice: injecting your database schema and its description into the prompt for even more accurate and context-aware AI-powered querying.

Best Practice 3: Inject Schema and Its Description into the Prompt

An example of how Locusive lets you include or exclude tables from your schema

While providing example queries and a reference guide can greatly improve the accuracy and context awareness of AI-powered database querying, there's one more best practice that can take your queries to the next level: injecting your database schema and its description directly into the prompt.

Injecting schema information into the prompt means providing the AI with a detailed description of your database structure every time it generates a query. This includes information about your tables, columns, data types, and relationships, all formatted in a way that's easy for the AI to parse and understand.

But why is this so important? By giving the AI direct access to your schema information in the prompt, you're essentially providing it with a cheat sheet to navigate your database. The AI can use this information to make more informed decisions about which tables and columns to use in the query, how to join them together, and what conditions to apply to filter and aggregate the data.

Here are some tips for effectively describing and formatting your schema information in the prompt:

  • Use a clear and consistent format, such as JSON or YAML, to describe your tables and columns
  • Include information about data types, primary and foreign keys, and any constraints or default values
  • Use descriptive names for your tables and columns that clearly convey their purpose and contents
  • Organize your schema description in a logical and easily navigable manner, such as by grouping related tables together
  • Provide examples of common query patterns or relationships that are specific to your database

Here's an example of how you might inject schema information into a prompt using JSON:

{
 "schema": [
   {
     "table": "customers",
     "columns": [
       {
         "name": "customer_id",
         "type": "integer",
         "primary_key": true
       },
       {
         "name": "first_name",
         "type": "varchar(50)"
       },
       {
         "name": "last_name",
         "type": "varchar(50)"
       },
       {
         "name": "email",
         "type": "varchar(100)",
         "unique": true
       }
     ]
   },
   {
     "table": "orders",
     "columns": [
       {
         "name": "order_id",
         "type": "integer",
         "primary_key": true
       },
       {
         "name": "customer_id",
         "type": "integer",
         "foreign_key": {
           "table": "customers",
           "column": "customer_id"
         }
       },
       {
         "name": "order_date",
         "type": "date"
       },
       {
         "name": "total_amount",
         "type": "decimal(10,2)"
       }
     ]
   }
 ]
}

In this example, we're providing the AI with a detailed description of two tables: "customers" and "orders". For each table, we're specifying the column names, data types, primary keys, foreign keys, and any unique constraints. This gives the AI a clear understanding of how the tables are structured and related to each other.

By injecting this schema information into the prompt, along with the user's natural language query and any relevant example queries, we're giving the AI all the tools it needs to generate an accurate and optimized SQL query.

The benefits of injecting schema information into the prompt are significant:

  • Improved query accuracy: By providing the AI with a clear understanding of your database structure, you're reducing the chances of generating queries with syntax errors, incorrect column names, or invalid join conditions.
  • Reduced errors and edge cases: With direct access to your schema information, the AI can catch potential errors or edge cases early on, such as trying to query a non-existent table or column.
  • Faster query generation: By having all the necessary information readily available in the prompt, the AI can generate queries more quickly and efficiently, without needing to make additional API calls or database lookups.
  • More context-aware results: By understanding the relationships and constraints between your tables and columns, the AI can generate more contextually relevant and meaningful query results.

Injecting your database schema and its description into the prompt is a powerful best practice that can take your AI-powered database querying to new heights. Combined with relevant example queries and a comprehensive reference guide, this technique can help you generate highly accurate, efficient, and context-aware queries with minimal effort.

But implementing these best practices can be challenging, especially if you're building your own AI-powered querying system from scratch. That's where tools like Locusive come in, which we'll explore in the next section.
