1、错误描述
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxError Exception:You have an error in your SQL syntax check the manual that corresponds to your MySQL server version for the right syntax to use near 'notnull,user_name varchar(255) )' at line 1
2、错误原因
StringBuilder sql = new StringBuilder();
sql.append("create table t_you_su_ta(");
sql.append(" id int primary key,");
sql.append(" user_id int notnull,");
sql.append(" user_name varchar(255))");
3、解决办法
在拼接user_id时,应改成“user_id int not null”
