mariadbHow to use XA transactions in Mariadb?

XA transactions are distributed transactions that allow multiple databases to be involved in a single transaction. In MariaDB, XA transactions are supported through the XA START, XA END, XA PREPARE, XA COMMIT, and XA ROLLBACK commands.

Example

XA START 'xid1'
INSERT INTO table1 VALUES (1,2,3);
XA END 'xid1';
XA PREPARE 'xid1';
XA COMMIT 'xid1';

The above example starts an XA transaction with the XA START command, inserts a row into a table with the INSERT command, ends the transaction with the XA END command, prepares the transaction with the XA PREPARE command, and commits the transaction with the XA COMMIT command.

Code explanation

1. XA START 'xid1': This command starts an XA transaction with the given transaction identifier (xid1).
2. INSERT INTO table1 VALUES (1,2,3): This command inserts a row into the table1 table with the given values.
3. XA END 'xid1': This command ends the XA transaction with the given transaction identifier (xid1).
4. XA PREPARE 'xid1': This command prepares the XA transaction with the given transaction identifier (xid1).
5. XA COMMIT 'xid1': This command commits the XA transaction with the given transaction identifier (xid1).
