java.sql.SQLException：数据库被锁定错误

Question

I'm in a situation where I get Database is locked on the statement:

pst = conn.prepareStatement(cIQuery);

Where pst is PreparedStatement object and conn is the Connection object and cIQuery is the query which is going to be executed. However, I have closed all the Connection , ResultSet and PreparedStatement objects in each class after use. How can I overcome this problem?

You may need to check the processes working on that database. You may be running your project multiple times and launching different processes as a result. So it may happen that some process is still alive and holding the database lock. Try checking the processes status using command
