Database Interface

-- Simple AI query from SQL Server
DECLARE @Response NVARCHAR(MAX);

EXEC sql2ai.AskAI
    @Prompt = 'Summarize the sales trend for Q4',
    @Response = @Response OUTPUT;

SELECT @Response;

-- Structured JSON response
DECLARE @Analysis NVARCHAR(MAX);

EXEC sql2ai.AskAI
    @Prompt = 'Analyze this customer feedback and extract sentiment',
    @Context = @CustomerFeedback,
    @ResponseFormat = 'json',
    @JsonSchema = '{
        "sentiment": "positive|negative|neutral",
        "confidence": "number",
        "key_themes": ["string"],
        "recommended_action": "string"
    }',
    @Response = @Analysis OUTPUT;

-- Parse JSON response
SELECT
    JSON_VALUE(@Analysis, '$.sentiment') AS Sentiment,
    JSON_VALUE(@Analysis, '$.confidence') AS Confidence,
    JSON_VALUE(@Analysis, '$.recommended_action') AS Action;

-- Multi-turn conversation
DECLARE @ConversationId UNIQUEIDENTIFIER = NEWID();

EXEC sql2ai.AskAI @ConversationId = @ConversationId,
    @Prompt = 'What are the top 3 selling products?',
    @Response = @Response1 OUTPUT;

EXEC sql2ai.AskAI @ConversationId = @ConversationId,
    @Prompt = 'Why do you think they sell well?',  -- Context preserved!
    @Response = @Response2 OUTPUT;

Guaranteed Response Formats

-- Ensure JSON response matches schema
EXEC sql2ai.AskAI
    @Prompt = 'Extract product information from this description',
    @Context = @ProductDescription,
    @ResponseFormat = 'json',
    @JsonSchema = '{
        "type": "object",
        "properties": {
            "name": {"type": "string"},
            "price": {"type": "number"},
            "category": {"type": "string", "enum": ["Electronics", "Clothing", "Food"]},
            "features": {"type": "array", "items": {"type": "string"}}
        },
        "required": ["name", "price", "category"]
    }',
    @MaxRetries = 3,  -- Retry if format invalid
    @Response = @Response OUTPUT;

-- Response is guaranteed to match schema or returns error
