java jdbc executeUpdate在自动提交模式下失败

Question

在postgresql数据库的自动提交模式下，若jdbc executeUpdate抛出SQLException，则表示数据库中的数据未被修改？或者我应该将自动提交设置为false并手动管理它

Answer 1

When a connection is created, it is in autocommit mode. This means that each individual SQL statement is treated as a transaction and is automatically committed right after it is executed. This is true for all JDBC drivers, including the PostgreSQL's one. To start a new transaction, we turn the autocommit off.
