发布失败，无法将数据插入MySQL表，其中列数与第1行的值数不匹配

Question

Unable to do insert data into MySql database using post method, getting the error java.sql.SQLException: Column count doesn't match value count at row 1 Below is my INSERT statement, it was working fine earlier, but after adding two new columns getting the above error. Following are the details about two new columns: PLAYER_STATUS, IsAdmin

PLAYER_STATUS varchar(250) NO Active - This column is not NULL with default value 'Active'
IsAdmin tinyint(1) NO 0 - This boolean column is not NULL with default value 0

PreparedStatement ps = conn.prepareStatement(
                                        "INSERT INTO mycoolmap.weekendsoccer_login values(default,?,?,?,?,?,?,?)",
                                        Statement.RETURN_GENERATED_KEYS);
                        ps.setString(1, p_Name);
                        ps.setString(2, p_Email);
                        ps.setString(3, p_Mobile);                      
                        ps.setString(4, encrptPass);                
                        ps.setString(5, p_Company);         
                        ps.setString(6, "Active");          // newly added column
                        ps.setInt(7, 0);                    // newly added column

                        x = ps.executeUpdate();

Answer 1

1. As @Scary has pointed out. You should specify the field names eg insert into table_name(field_1, field_2) value (?, ?) .
2. If you need set default value for a row and you have role to controller over MySQL. You should do that in SQL, that safer (but less flexible). eg

 CREATE TABLE weekendsoccer_login( id INT(11) NOT NULL UNIQUE AUTO_INCREMENT, ... status varchar(255) NOT NULL DEFAULT "Active", ... PRIMARY KEY (id) ); 

3. For learning JDBC, I'm sure you're doing good. But if you really want to go for production, you should take a look at JPA ( Hibernate or EclipseLink implementation) or jOOQ (I love this one, really handy and save a lot of time)
