java - com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException。 WHERE 子句

Question

在 NetBeans 中运行文件 Aspirantes.java 时出现 MySQL 语法错误:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 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 'telefono1 = '01 800 021 1000',telefono2 = '01 800 433 2000',carrera = 'IT',promedio = '100',WHERE ficha = 6' at line 1

我不知道出了什么问题。 java 代码可以在 http://www.mediafire.com/view/?i37ccovyvcky8ai 看到(和下载)。 。错误似乎出现在 MySQL UPDATE 语句的第 584 到 596 行中。

“datos”表如下所示:

知道如何解决这个问题吗？预先非常感谢您。干杯!

Answer 1

这是您当前的代码:

sSQL = "UPDATE datos " +
            "SET apellido1 = ?," +
            "apellido2 = ?," +
            "nombre = ?," +
            "genero = ?," +
            "telefono1 = ?," +
            "telefono2 = ?," +
            "carrera = ?," +
            "promedio = ?," +  // <<== remove this trailing comma
            "WHERE ficha = " +id_actualizar;

问题是在 WHERE 子句之前有多余的逗号。
