mySQL表创建查询语法错误

Question

//请任何人都可以告诉我这个MySQL查询语法有什么问题？

String createTableSQL = "" 
       + " CREATE TABLE location(" 
       + " location_id INTEGER PRIMARY KEY AUTOINCREMENT," 
       + " location_name VARCHAR(30)," 
       + " addr VARCHAR(30)," 
       + ")"; 

Answer 1

删除最后一个变化AUTOINCREMENT在AUTO_INCREMENT并添加PRIMARY KEY（location_id）

String createTableSQL = "" 
      + " CREATE TABLE location(" 
      + " location_id INTEGER PRIMARY KEY AUTO_INCREMENT," 
      + " location_name VARCHAR(30)," 
      + " addr VARCHAR(30)," 
      + " PRIMARY KEY (`location_id `))";
