jdbc executeUpdate在自动提交模式下失败

Question

in autocommit mode on postgresql database, if jdbc executeUpdate throws SQLException it means that no data on database was modify? or i should set autocommit to false and manage it manually?

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.
