SQL Database Engine Programming

Welcome to the comprehensive programming guide for the SQL Database Engine. This section covers the essential tools, languages, and APIs you need to develop powerful and efficient database solutions.

Key Programming Areas

Sample Code Snippets

Here are a few common examples to get you started:

Creating a Simple Stored Procedure (T-SQL)

CREATE PROCEDURE usp_GetCustomerOrders
                @CustomerID INT
            AS
            BEGIN
                SELECT
                    o.OrderID,
                    o.OrderDate,
                    od.ProductID,
                    od.Quantity
                FROM
                    Orders o
                JOIN
                    OrderDetails od ON o.OrderID = od.OrderID
                WHERE
                    o.CustomerID = @CustomerID;
            END;
            GO

CLR Function Example (C#)

[Microsoft.SqlServer.Server.SqlFunction]
            public static SqlInt32 AddNumbers(SqlInt32 a, SqlInt32 b)
            {
                if (a.IsNull || b.IsNull)
                    return SqlInt32.Null;
                else
                    return new SqlInt32(a.Value + b.Value);
            }
