此mysql脚本无法正常运行。我尝试执行查询以在phpmyadmin中创建表并且它有效。创建了数据库但是没有创建表,我没有得到任何错误/堆栈跟踪。 这是我的代码
public void createDatabase() {
java.sql.Connection conn = null;
java.sql.Statement stmt = null;
try{
// Register JDBC driver
Class.forName("com.mysql.jdbc.Driver");
// Open a connection
System.out.println("Connecting to a selected database...");
conn = DriverManager.getConnection(DB_URL, USER, PASS);
System.out.println("Connected database successfully...");
// Create database
System.out.println("Creating table in given database...");
stmt = conn.createStatement();
String createdatabase = "CREATE DATABASE TimePoints;";
stmt.executeUpdate(createdatabase);
System.out.println("Created the database.");
// Create table
System.out.println("Creating table in given database...");
stmt = conn.createStatement();
String createtable = "CREATE TABLE players (playername VARCHAR(38), playertime BIGINT);";
stmt.executeUpdate(createtable);
System.out.println("Created the table.");
}catch(SQLException se){
// Handle errors for JDBC
se.printStackTrace();
}catch(Exception e){
// Handle errors for Class.forName
e.printStackTrace();
}finally{
// Finally block used to close resources
try{
if(stmt!=null)
conn.close();
}catch(SQLException se){
}// do nothing
try{
if(conn!=null)
conn.close();
}catch(SQLException se){
se.printStackTrace();
} //end finally try
} //end try
System.out.println("Goodbye!");
}
