JDBC inserts data into the database to obtain the primary key. Currently, I have summarized two methods:1. Applicable to databases with auto-increment columns (such as SQL-server and mysql)/*** Insert data to obtain the primary key* @ Param annex* @ Return*/Public long save2 (Annex annex ){Long queue id = 0;// Obtain the connectionConnection con = ProxoolManager. getConnection ();String insertSQL = "insert into annex values (?,?, Sysdate ,?,?,?)

create bridges between Java programs and data sources. The application needs to be written once and can be moved to a variety of drivers to run. Sun provides a driver manager, a database vendor-such as MySQL, Oracle, which provides drivers that meet the requirements of the driver manager and can be identified to work properly. Therefore, JDBC is not limited by the database vendor.The

Jdbc oracle Transaction ProcessingDatabase transactions:In a database, transactions refer to a group of logical operation units that transform data from one state to another.To ensure data consistency in the database, data manipulation should be a discrete logical unit in a group: when it is allData Consistency can be maintained upon completion. When some operations in this unit fail, the entire transaction
