当我尝试使用GridView页脚模板将数据插入oracle数据库中的数据插入到oracle数据库中时，在插入查询中出现此“ ORA-01008：未绑定所有变量”错误，我在服务器上测试了查询而且效果很好，但是当我尝试运行该应用并使用添加按钮执行查询时，它会显示错误
**网格视图代码正在使用模板字段，因此我可以编辑页脚模板的网格视图**

string query = "INSERT INTO members (member_id, user_name,address ,mob_number,email_address,password ) VALUES (:member_id, :user_name,:address ,:mob_number,:email_address,:password)";
OleDbCommand add = new OleDbCommand(query, coon);
add.Parameters.AddWithValue(":member_id", (gvmb.FooterRow.FindControl("member_idfooter") as TextBox).Text.Trim());

如果您可以改为使用OracleCommand，则可以使用特定于Oracle的OracleParamater来使其工作。
cmd.Parameters.Add(new OracleParameter("client", client));
取决于您拥有的命名空间是Oracle.DataAccess.Client还是System.Data.OracleClient，您可以使用AddWithValue版本。

解决了，我只是将查询中的：参数更改为？我猜它起作用了，参数顺序
插入INTO成员（member_id，用户名，地址，mob_number，电子邮件地址，密码）VALUES（？，？，？，？，？，？）
