How can you group one or more SQL statements together as one logical unit?Create a stored procedureCreate a TRANSACTION and then COMMITCreate a LOCK and COMMIT

You can group one or more SQL statements together as one logical unit in several ways:

1. Create a Stored Procedure: A stored procedure is a prepared SQL code that you can save, so the code can be reused over and over again. Here are the steps to create a stored procedure:

   • Use the CREATE PROCEDURE statement to create a stored procedure.
   • Give the stored procedure a name.
   • Define the SQL statements that should be included in the stored procedure. These statements should be within the BEGIN and END keywords.
   • Finally, execute the stored procedure using the CALL statement.

2. Create a Transaction and then Commit: A transaction is a unit of work that is performed against a database. Transactions are units or sequences of work accomplished in a logical order. Here are the steps to create a transaction:

   • Begin the transaction with the BEGIN TRANSACTION statement.
   • Define the SQL statements that should be included in the transaction.
   • If everything is in order, commit the transaction using the COMMIT statement. If there are any errors, you can roll back the transaction using the ROLLBACK statement.

3. Create a Lock and Commit: Locking is a mechanism that prevents data from being changed by more than one user at a time. Here are the steps to create a lock:

   • Begin the transaction with the BEGIN TRANSACTION statement.
   • Define the SQL statements that should be included in the transaction.
   • Lock the data that you want to change using the LOCK TABLE statement.
   • If everything is in order, commit the transaction using the COMMIT statement. If there are any errors, you can roll back the transaction using the ROLLBACK statement.

Remember, it's important to always handle transactions and locks correctly to prevent data inconsistencies and to maintain data integrity.
