SQL Writer

AI DDL & Code Generation

Beyond simple text-to-SQL. Generate complete stored procedures, views, and functions with proper error handling, transactions, audit trails, and security best practices.

Beyond Text-to-SQL

Traditional AI SQL Tools

"Show me sales by region"

SELECT region, SUM(amount)
FROM sales
GROUP BY region
  • Only generates SELECT queries
  • No error handling
  • No transaction support
  • No business logic

SQL Writer

"Create a fund transfer procedure with overdraft protection"

CREATE PROCEDURE TransferFunds
  @FromAccount INT,
  @ToAccount INT,
  @Amount DECIMAL(18,2)
AS
BEGIN
  SET XACT_ABORT ON;
  BEGIN TRY
    BEGIN TRANSACTION;
    -- Validation, locking, audit...
    COMMIT;
  END TRY
  BEGIN CATCH
    ROLLBACK;
    THROW;
  END CATCH
END

Your Request

"Create a stored procedure to transfer funds between accounts with proper locking, audit trail, and overdraft protection. It should validate both accounts exist and the source has sufficient funds."

Generated Output

    @TargetAccountId INT,
    @Amount DECIMAL(18,2),

    SET NOCOUNT ON;
    SET XACT_ABORT ON;

    DECLARE @SourceBalance DECIMAL(18,2);
    DECLARE @TransferId INT;

    BEGIN TRY
        BEGIN TRANSACTION;

        -- Acquire locks in consistent order
        SELECT @SourceBalance = Balance
        FROM dbo.Accounts WITH (UPDLOCK, HOLDLOCK)
        WHERE AccountId = @SourceAccountId;

        IF @SourceBalance IS NULL

        VALUES

        SET @TransferId = SCOPE_IDENTITY();

        COMMIT TRANSACTION;

        SELECT @TransferId AS TransferId,
               'Success' AS Status;
    END TRY
