Handling Transactions
Go database transactions use Begin and Commit for integrity.
Understanding Database Transactions
Database transactions are a crucial part of ensuring data integrity in any application. They allow a series of operations to be executed as a single unit, which either completely succeeds or fails, ensuring that the database remains in a consistent state.
Initiating a Transaction with Begin
In Go, transactions are initiated using the Begin method. This method starts a new transaction and returns a *sql.Tx object, which represents the transaction in progress.
Committing a Transaction
Once all operations within a transaction are executed and no errors are encountered, the Commit method is used to save the changes to the database. If an error occurs before the commit, the transaction can be rolled back using the Rollback method to revert any changes made during the transaction.
Error Handling in Transactions
Proper error handling is essential in transactions to maintain data integrity. Always check for errors after each operation within a transaction, and roll back if necessary. Using defer with tx.Rollback() ensures that a transaction is not left open if an error occurs.
Using Transactions for Integrity
Transactions should be used whenever you have multiple operations that need to be treated as a single action. This is particularly important for operations involving multiple tables or when ensuring that operations do not leave the database in an inconsistent state.
