Question

将数据从java表单插入MySql数据库详细信息表个人

但我收到错误列数与第1行的值计数不匹配

我正在使用Netbeans 6.9，MySql 5.6

我已将ID声明为int，主键，Phone和mobile为int，其他所有为char。

  Database - ID, Name, Address, Gender, Education, Phone, Mobile, DOB.

Answer 1

使用以下内容纠正您的INSERT声明：

String s = "insert into 
            personal(ID, Name,Address, Gender, Education, Phone, Mobile, DOB) 
            values (" + "'" + t.getText() + "','" + t.getText() + "','" 
            + t.getText() + "','" + t.getText() + "','" + t.getText() + "','"
            + t.getText() + "','" + t.getText() + "','" + t.getText() + "')";

将t.getText()替换为您的PreparedStatement，现在它应该有效。

注意：但我建议您使用Statement而不是?并使用占位符 {{1}} 。这个解决方案更干净，更安全！（SQL injection）更具人性化。
