Question

错误:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'lock WHERE player='SrLolok'' at line 1

代码:

PreparedStatement search = instance.getConnection().prepareStatement("SELECT * FROM lock WHERE player=?;");
search.setString(1, player);
ResultSet rs = search.executeQuery();

Answer 1

lock 是 reserved word in MySQL .

如果要使用它，需要用反引号括起来:

SELECT * FROM `lock` WHERE player=?

或者更好的是，使用与保留字不对应的表名，这样您就不必担心这一点。
