Question

我在MySQL中有下表“test_tbl1”。它有“id，name，sal”列。我在eclipse中使用以下代码并尝试从Excel中插入数据。我从excel获取的每一行都收到以下错误。

FAILED: testDataProviderExample("101", "sam", "10000")

    System.out.println("id: " + empid);

    System.out.println("name: " + name);

    System.out.println("sal: " + sal);
    System.out.println("hi2");
    String sql = "insert into test_tbl(id,name,sal)" + "values(?,?,?)";
    Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root", "admin");
    PreparedStatement preparedStatement = conn.prepareStatement(sql);

    preparedStatement.setString(2, "name");
    preparedStatement.setString(3, "sal");
    preparedStatement.executeUpdate();
    }

Answer 1

你说你有一个表名test_tbl1，但你的查询说

String sql = "insert into test_tbl(id,name,sal)" + "values(?,?,?)";

我认为你必须修改sql：

String sql = "insert into test_tbl1 (id,name,sal)" + "values(?,?,?)";

Answer 2

错误表示您插入的表中没有名为name的列。这可能是因为您有一个名为test_tbl1的表，但您的代码引用了test_tbl。这假定存在test_tbl并且没有该列。尝试使用mysql客户端手动运行SQL。

另外，你的表名很差，我认为这是一张员工表，如果这样称之为员工，你就会避免类似的错误。

以下连接是不必要的：

String sql = "insert into test_tbl(id,name,sal)" + "values(?,?,?)";

我很震惊这个错误（MySQLSyntaxErrorException：'字段列表'中的未知列'名称'）
