BEGIN; is formatted as BEGIN TRANSACTION;, which is invalid in MySQL #1553
Description
BEGIN; is valid in MySQL, but not BEGIN TRANSACTION;: https://dev.mysql.com/doc/refman/8.4/en/commit.html
But sqlparser does not preserve the exact syntax of the statement, and always formats it as BEGIN TRANSACTION;, causing an execution error in MySQL.
