SpringMVC中出现的sql语句错误
1、原sql语句：select `major_id` AS 'majorId' ,`major_name` AS 'majorName',tuition,`dept_id` as 'deptId' from tb_major where major_id = ?
出现问题：Request processing failed: org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [select `major_id` AS 'majorId' ,`major_name` AS 'majorName',tuition,`dept_id` as 'deptId' from tb_major where major_id = ?]
解决办法：
String sql = "select `major_id` AS 'majorId' ,`major_name` AS 'majorName',tuition,`dept_id` as 'deptId' from tb_major where major_id = ' "+majorId.trim()+" ' ";
2、原语句：String sql = "update tb_major set major_name =? and tuition =? where major_id=?";
出现的问题与第一题类似：
提示：bad SQL grammar
解决办法：
String sql = "update tb_major set major_name =? ，tuition =? where major_id=?";
将and改为 , (逗号）即可
