我有一个数据源和一个网格视图，我正在尝试在gridview行上启用编辑。一切都很完美，所以我可以点击编辑，字段更改为文本框，取消和更新按钮apear和工作但如果我更改值并单击更新按钮我得到错误：

ORA-01036：非法变量名称/编号

任何想法为什么？我检查了updatecommand中的所有拼写，这一切都是正确的。请帮帮我。

为什么会出现这种情况有很多原因。有时因为我们不使用Oracle工具，有时因为gridview标记不正确。

因为您不需要更新Column charge_id的值，所以除非您在DataKeyNames SqlDataSource属性中指定它，否则不能使用BoundField。

如果未在DataKeyNames中指定BoundField，则生成一个绑定变量，如果在update语句中未使用该变量将导致ORA-01036。要避免错误，请在DataKeyNames属性中指定此字段或将其更改为TemplateField并使用Eval.so我认为有两种可能的情况：

1。）将SqlDataSource的DataKeyNames属性设置为charge_id。

<asp:SqlDataSource ID="charges_gv_datasource" runat="server" ConnectionString="edited"
 ProviderName="System.Data.OracleClient" 
 DataKeyNames="charge_id"
 SelectCommand="WITH relevant_ids AS (SELECT ir.result_id AS relevant_result_id 
 FROM inspection_result_tbl ir) SELECT ir.charge_id, ....." 
 UpdateCommand="UPDATE [charges_tbl] SET [CLAIM_VERIFICATION] = :claim_verification,...">

2。）如果选项1不适合：

看到你的标记，肯定你已经有了<EditItemTemplate>，因为许多<asp:TemplateField>项目没有显示相同的内容。

确保您将charge_id列放在<asp:TemplateField>中。使用<asp:Lable>即使在编辑模式下也不会更改。

<asp:TemplateField HeaderText="charge_id" SortExpression="charge_id">
<EditItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("charge_id") %>'></asp:Label>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("charge_id") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>

看到稍后提供的堆栈跟踪，：最好将VS开发人员工具（ODT）用于VS和ODP.NET，因为它们可以更好地与.NET和Oracle集成。

ODP.NET使用Oracle.DataAccess.Client命名空间。 System.Data.OracleClient属于Oracle的MS提供程序。 web.config中的连接字符串需要使用Oracle.DataAccess.Client，如下所示：

<connectionStrings>
<add name="ConnectionString1" 
 connectionString="Data Source=192.168.1.104/orcl;Persist Security Info=True;User    
 ID=system;Password=xxxxxx;"
 providerName="Oracle.DataAccess.Client" />
</connectionStrings>
