• CROSS APPLY and OUTER APPLY - Table-valued function joins

• MERGE statements - Upsert operations in single statement

Stored Procedures

• CREATE PROCEDURE syntax

• Input and output parameters

• Error handling with TRY-CATCH

SQL Server Query Examples

Pagination with OFFSET-FETCH

Input: “Get page 3 of products, 20 items per page, sorted by price”

SELECT ProductId, Name, Price, Category
 FROM Products
 ORDER BY Price
 OFFSET 40 ROWS
 FETCH NEXT 20 ROWS ONLY;

PIVOT Operation

Input: “Show monthly sales by region as columns”

SELECT Region, [January], [February], [March], [April]
 FROM (
  SELECT Region, MonthName, SalesAmount
  FROM MonthlySales
 ) AS SourceTable
 PIVOT (
  SUM(SalesAmount)
  FOR MonthName IN ([January], [February], [March], [April])
 ) AS PivotTable;

MERGE Statement

Input: “Update existing products or insert new ones from staging table”

MERGE INTO Products AS Target
 USING StagingProducts AS Source
 ON Target.ProductId = Source.ProductId
 WHEN MATCHED THEN
  UPDATE SET 
  Name = Source.Name,
  Price = Source.Price,
  UpdatedAt = GETDATE()
 WHEN NOT MATCHED BY TARGET THEN
  INSERT (ProductId, Name, Price, CreatedAt)
  VALUES (Source.ProductId, Source.Name, Source.Price, GETDATE())
 WHEN NOT MATCHED BY SOURCE THEN
  DELETE;

Stored Procedure with Error Handling

Input: “Create procedure to transfer money between accounts”

CREATE PROCEDURE TransferFunds
  @FromAccountId INT,
  @ToAccountId INT,
  @Amount DECIMAL(18,2),
  @TransferId INT OUTPUT
 AS
 BEGIN
  SET NOCOUNT ON;
  BEGIN TRY
  BEGIN TRANSACTION;
  
  UPDATE Accounts SET Balance = Balance - @Amount 
  WHERE AccountId = @FromAccountId;
  
  IF @@ROWCOUNT = 0
  RAISERROR('Source account not found', 16, 1);
  
  UPDATE Accounts SET Balance = Balance + @Amount 
  WHERE AccountId = @ToAccountId;
  
  IF @@ROWCOUNT = 0
  RAISERROR('Destination account not found', 16, 1);
  
  INSERT INTO Transfers (FromAccount, ToAccount, Amount, TransferDate)
  VALUES (@FromAccountId, @ToAccountId, @Amount, GETDATE());
  
  SET @TransferId = SCOPE_IDENTITY();
  
  COMMIT TRANSACTION;
  END TRY
  BEGIN CATCH
  IF @@TRANCOUNT > 0
  ROLLBACK TRANSACTION;
  THROW;
  END CATCH
 END;
