The OpenAI-Databricks SQL Integration: A Technical Deep Dive
To leverage the power of natural language querying, a sophisticated system integrating OpenAI's language models with Databricks SQL is required. Here's an in-depth look at the process:
1. Advanced Metadata Collection
In 2025, metadata collection goes beyond simple schema information. Modern systems now capture:
- Table relationships and foreign key constraints
- Frequently used join paths
- Query performance statistics
- Data lineage information
Here's an example of how this enhanced metadata collection might look in Python:
from databricks import sql
import networkx as nx
class EnhancedEndpointManager:
def __init__(self, server_hostname, http_path, access_token):
self.connection = sql.connect(
server_hostname=server_hostname,
http_path=http_path,
access_token=access_token
)
self.graph = nx.DiGraph()
def get_enhanced_schema(self):
schemas = {}
with self.connection.cursor() as cursor:
# Get table schemas
cursor.execute("SHOW TABLES")
tables = cursor.fetchall()
for table in tables:
table_name = f"{table[0]}.{table[1]}"
cursor.execute(f"DESCRIBE TABLE {table_name}")
columns = cursor.fetchall()
schemas[table_name] = [col[0] for col in columns]
# Get foreign key relationships
cursor.execute(f"SHOW TBLPROPERTIES {table_name}")
properties = cursor.fetchall()
for prop in properties:
if prop[0].startswith('fk_'):
fk_info = prop[1].split(',')
self.graph.add_edge(table_name, fk_info[2], key=fk_info[1])
return schemas, self.graph
def get_common_join_paths(self):
return list(nx.all_pairs_shortest_path(self.graph))
def get_query_stats(self):
with self.connection.cursor() as cursor:
cursor.execute("SELECT query, execution_time FROM system.query_history ORDER BY start_time DESC LIMIT 100")
return cursor.fetchall()
This enhanced metadata provides a richer context for the AI model to understand the database structure and usage patterns.
2. Context-Aware Prompt Engineering
With more comprehensive metadata, prompt engineering becomes more sophisticated. The 2025 approach includes:
- Dynamic context selection based on the user's query
- Inclusion of relevant query statistics and common join paths
- Adaptive prompting that learns from past interactions
Here's an example of an advanced prompt generation function:
def create_advanced_prompt(schemas, graph, common_joins, query_stats, user_query):
prompt = "### Databricks SQL Database Context:\n"
# Add schema information
for table, columns in schemas.items():
prompt += f"# {table}({', '.join(columns)})\n"
# Add relationship information
prompt += "\n### Table Relationships:\n"
for edge in graph.edges(data=True):
prompt += f"# {edge[0]} -> {edge[1]} (via {edge[2]['key']})\n"
# Add common join paths
prompt += "\n### Frequently Used Join Paths:\n"
for path in common_joins[:5]: # Include top 5 common joins
prompt += f"# {' -> '.join(path)}\n"
# Add query statistics
prompt += "\n### Recent Query Performance:\n"
for query, time in query_stats[:5]: # Include top 5 recent queries
prompt += f"# {query[:50]}... : {time}ms\n"
prompt += f"\n### User Query: {user_query}\n"
prompt += "Based on the above context, generate an optimized SQL query to answer the user's question:\n\nSELECT"
return prompt
This context-rich prompt provides the AI model with a comprehensive understanding of the database structure, relationships, and usage patterns, enabling it to generate more accurate and efficient SQL queries.
3. Advanced OpenAI API Interaction
In 2025, interaction with OpenAI's API has evolved to include:
- Model selection based on query complexity
- Fine-tuning options for domain-specific knowledge
- Streaming responses for real-time query generation
Here's an example of an advanced OpenAI API interaction:
import openai
def generate_optimized_sql(prompt, api_key, complexity='medium'):
openai.api_key = api_key
model_selection = {
'low': 'text-davinci-003',
'medium': 'gpt-4',
'high': 'gpt-4-32k'
}
response = openai.ChatCompletion.create(
model=model_selection.get(complexity, 'gpt-4'),
messages=[
{"role": "system", "content": "You are an expert SQL query generator. Your task is to create efficient, optimized SQL queries based on natural language inputs and database context."},
{"role": "user", "content": prompt}
],
temperature=0.1,
max_tokens=500,
top_p=1,
frequency_penalty=0,
presence_penalty=0,
stream=True
)
full_response = ""
for chunk in response:
if chunk.choices[0].delta.content is not None:
full_response += chunk.choices[0].delta.content
return full_response.strip()
This advanced API interaction allows for more nuanced and efficient query generation, adapting to the complexity of the user's request.
4. Intelligent Query Execution and Optimization
In 2025, query execution goes beyond simply running the generated SQL. Modern systems now include:
- Automatic query plan optimization
- Adaptive execution based on real-time data statistics
- Parallel and distributed query processing
Here's an example of how this might be implemented:
from databricks import sql
import time
class IntelligentQueryExecutor:
def __init__(self, connection):
self.connection = connection
def execute_query(self, query):
with self.connection.cursor() as cursor:
start_time = time.time()
cursor.execute("EXPLAIN ANALYZE " + query)
plan = cursor.fetchall()
# Analyze query plan and suggest optimizations
optimized_query = self.optimize_query(query, plan)
cursor.execute(optimized_query)
results = cursor.fetchall()
execution_time = time.time() - start_time
return results, execution_time, plan
def optimize_query(self, query, plan):
# Implement query optimization logic based on the execution plan
# This could include adjusting join orders, adding indexes, or using materialized views
# For simplicity, we'll just return the original query here
return query
This intelligent query execution system ensures that the generated SQL is not only syntactically correct but also optimized for performance on the specific Databricks SQL cluster.
5. Dynamic Result Presentation
The final step in the process is presenting the query results in a meaningful way. In 2025, this goes beyond simple tabular output:
- Automatic selection of appropriate visualization types
- Natural language summaries of key insights
- Interactive dashboards generated on-the-fly
Here's a conceptual example of how this might work:
import pandas as pd
import plotly.express as px
import openai
class DynamicResultPresenter:
def __init__(self, api_key):
self.api_key = api_key
def present_results(self, results, query):
df = pd.DataFrame(results)
# Determine appropriate visualization
viz_type = self.suggest_visualization(df)
# Generate visualization
fig = self.create_visualization(df, viz_type)
# Generate natural language summary
summary = self.generate_summary(df, query)
return fig, summary
def suggest_visualization(self, df):
# Logic to determine the best visualization type based on the data
# This could use machine learning models trained on historical data
pass
def create_visualization(self, df, viz_type):
if viz_type == 'scatter':
return px.scatter(df, x=df.columns[0], y=df.columns[1])
elif viz_type == 'bar':
return px.bar(df, x=df.columns[0], y=df.columns[1])
# Add more visualization types as needed
def generate_summary(self, df, query):
summary_prompt = f"Given the following data and original query, provide a concise summary of the key insights:\n\nData: {df.to_string()}\n\nOriginal Query: {query}"
response = openai.Completion.create(
engine="text-davinci-002",
prompt=summary_prompt,
max_tokens=150,
temperature=0.3
)
return response.choices[0].text.strip()
This dynamic result presentation system ensures that users not only receive the raw data they requested but also gain meaningful insights from it.
Real-World Applications: Natural Language Querying in Action
Let's explore some practical examples of how this advanced natural language querying system is being used in various industries in 2025:
1. Healthcare Analytics
User Query: "Show me the correlation between patient readmission rates and length of stay for each department over the last year, accounting for patient age and comorbidities."
Generated SQL:
WITH patient_data AS (
SELECT
d.department_name,
p.patient_id,
p.age,
a.length_of_stay,
CASE WHEN a.readmitted_within_30_days = 1 THEN 1 ELSE 0 END AS readmitted,
COUNT(c.condition_id) AS comorbidity_count
FROM
healthcare.patients p
JOIN healthcare.admissions a ON p.patient_id = a.patient_id
JOIN healthcare.departments d ON a.department_id = d.department_id
LEFT JOIN healthcare.patient_conditions c ON p.patient_id = c.patient_id
WHERE
a.admission_date >= DATE_SUB(CURRENT_DATE(), INTERVAL 1 YEAR)
GROUP BY
d.department_name, p.patient_id, p.age, a.length_of_stay, a.readmitted_within_30_days
)
SELECT
department_name,
AVG(length_of_stay) AS avg_length_of_stay,
AVG(readmitted) AS readmission_rate,
CORR(length_of_stay, readmitted) AS correlation,
AVG(age) AS avg_age,
AVG(comorbidity_count) AS avg_comorbidities
FROM
patient_data
GROUP BY
department_name
ORDER BY
correlation DESC
This query demonstrates the system's ability to handle complex healthcare analytics, incorporating multiple factors and providing valuable insights for hospital management.
2. Financial Fraud Detection
User Query: "Identify potentially fraudulent transactions by looking at unusual patterns in transaction amounts, frequencies, and locations compared to each customer's historical behavior over the past month."
Generated SQL:
WITH customer_stats AS (
SELECT
customer_id,
AVG(amount) AS avg_amount,
STDDEV(amount) AS stddev_amount,
COUNT(*) / 30 AS avg_daily_transactions,
APPROX_PERCENTILE(amount, 0.95) AS amount_95th_percentile,
COUNT(DISTINCT location) AS distinct_locations
FROM
finance.transactions
WHERE
transaction_date >= DATE_SUB(CURRENT_DATE(), INTERVAL 1 MONTH)
GROUP BY
customer_id
),
recent_transactions AS (
SELECT
t.*,
c.avg_amount,
c.stddev_amount,
c.avg_daily_transactions,
c.amount_95th_percentile,
c.distinct_locations
FROM
finance.transactions t
JOIN customer_stats c ON t.customer_id = c.customer_id
WHERE
t.transaction_date >= DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY)
)
SELECT
t.transaction_id,
t.customer_id,
t.amount,
t.transaction_date,
t.location,
(t.amount - t.avg_amount) / NULLIF(t.stddev_amount, 0) AS amount_zscore,
t.amount / NULLIF(t.amount_95th_percentile, 0) AS amount_percentile_ratio,
COUNT(*) OVER (PARTITION BY t.customer_id) / t.avg_daily_transactions AS frequency_ratio,
CASE WHEN t.location NOT IN (
SELECT DISTINCT location
FROM finance.transactions
WHERE customer_id = t.customer_id
AND transaction_date < DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY)
) THEN 1 ELSE 0 END AS is_new_location
FROM
recent_transactions t
WHERE
(t.amount - t.avg_amount) / NULLIF(t.stddev_amount, 0) > 3
OR t.amount > t.amount_95th_percentile * 2
OR COUNT(*) OVER (PARTITION BY t.customer_id) > t.avg_daily_transactions * 3
OR (
CASE WHEN t.location NOT IN (
SELECT DISTINCT location
FROM finance.transactions
WHERE customer_id = t.customer_id
AND transaction_date < DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY)
) THEN 1 ELSE 0 END
) = 1
ORDER BY
(t.amount - t.avg_amount) / NULLIF(t.stddev_amount, 0) DESC,
t.amount / NULLIF(t.amount_95th_percentile, 0) DESC
This sophisticated query showcases the system's ability to generate complex fraud detection logic, incorporating statistical analysis and historical comparisons.
3. Supply Chain Optimization
