How to manage transactions
and locking

Excercises using the My Guitar Shop Database

Use Microsoft SQL Server

 

  1. Write a script that includes these statements coded as a transaction:

INSERT Orders

VALUES (3, GETDATE(), '10.00', '0.00', NULL, 4,

  'American Express', '378282246310005', '04/2019', 4);

 

SET @OrderID = @@IDENTITY;

 

INSERT OrderItems

VALUES (@OrderID, 6, '415.00', '161.85', 1);

 

INSERT OrderItems

VALUES (@OrderID, 1, '699.00', '209.70', 1);

Here, the @@IDENTITY variable is used to get the order ID value that’s automatically generated when the first INSERT statement inserts an order.

If these statements execute successfully, commit the changes. Otherwise, roll back the changes.

Follow-up Question

I am getting this error with the EXCEPTION

### SQL Transaction Script This snippet is an SQL script demonstrating the use of transactions with error handling. The script performs a sequence of database operations, inserting data into two tables: `Orders` and `OrderItems`. **Code Breakdown:** - **BEGIN;** Initializes a transaction block. - **DECLARE @OrderID INT** Declares a variable `@OrderID` of type integer. - **INSERT Orders** Inserts a new record into the `Orders` table with the specified values. It uses the `GETDATE()` function for the current date and the `@@IDENTITY` function to retrieve the last inserted identity value to store in `@OrderID`. ```sql VALUES (3, GETDATE(), '10.00', '0.00', NULL, 4, 'American Express', '378282246310005', '04/2019', 4); ``` - **INSERT OrderItems** Inserts two new records into the `OrderItems` table, using the previously retrieved `@OrderID` for referential integrity. ```sql VALUES (@OrderID, 6, '415.00', '161.85', 1); VALUES (@OrderID, 1, '699.00', '209.70', 1); ``` - **COMMIT** Commits the transaction if all operations are successful, printing a success message. - **PRINT 'The transaction was committed.';** Outputs a message indicating the transaction was successful. - **EXCEPTION Handling Section** This part is intended to handle any errors that occur during the transaction. ```sql WHEN OTHERS THEN ROLLBACK; PRINT 'The transaction was rolled back.'; ``` Note: In T-SQL (SQL Server), the correct syntax for error handling uses `BEGIN TRY...END TRY` and `BEGIN CATCH...END CATCH` blocks. The `EXCEPTION` keyword and `WHEN OTHERS THEN` are not valid in T-SQL, which results in a syntax error. **Error Message:** - **Msg 102, Level 15, State 1, Line 67** Indicates a syntax error near the `EXCEPTION` keyword. This part of the code needs correction to properly handle exceptions. **Suggestions for Correction:** - Replace the `EXCEPTION` block with T-S
