SQL 语法错误排查指南:如何解决 "You have an error in your SQL syntax" ?
解决“you have an error in your sql syntax”错误
这个问题出现的原因在于sql语句中存在语法错误。这个问题涉及的错误是:
java.sql.sqlsyntaxerrorexception: 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 'from graduate-college' at line 6
仔细检查后,发现问题出在一个多余的逗号。修改后的正确语句如下:
select date-year, college-name , graduate-number , employment-number , id from graduate-college
此外,还可以看到有些字段的名称包含连字符(-)。在数据库设计中,建议使用帕斯卡命名法或蛇形命名法。帕斯卡命名法首字母大写,而蛇形命名法用下划线分隔单词。
select date-year, collegename , graduatenumber , employmentnumber , id from graduatecollege
或者
select `date-year`, `college-name`, `graduate-number`, `employment-number`, `id` from `graduate-college`
