c# - ORA-01006 : bind variable does not exist ASP. 网络

Question

我是 ASP.NET 编码方面的新手，所以如果我遗漏了一些明显的东西，请原谅我。

我正在编写一个数据输入页面，其中我有一个 FormView 设置为默认插入以处理插入，我有一个 gridview 来查看表中的数据并允许编辑。

gridview 的编辑工作完美，但是 FormView 让我失望。当我在 FormView 中点击插入时，我得到一个 ORA-01006:绑定(bind)变量不存在。

我正在使用的 SQLDataSource 指向一个 Oracle 数据库。

我的 FormView 代码是:

<asp:FormView ID="FormView1" runat="server" CellPadding="4" DataKeyNames="DATAKEY" DataSourceID="Oracle" DefaultMode="Insert" ForeColor="#333333" HorizontalAlign="Left">

        <EditRowStyle BackColor="#999999" />
        <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
        <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
        <InsertItemTemplate>
         <table>
         <tr>
             <td align="center">Year :</td>
             <td width="30px"><asp:TextBox ID="YearTextBox" runat="server" Text='<%# Bind("YEAR") %>'></asp:TextBox><br /></td>
         </tr>
          <tr>
             <td align="center">Week :</td>
             <td width="30px"><asp:TextBox ID="WeekTextBox" runat="server" Text='<%# Bind("WEEK") %>'></asp:TextBox><br /></td>
         </tr>
          <tr>
             <td align="center">Store :</td>
             <td width="30px"><asp:TextBox ID="StoreTextBox" runat="server" Text='<%# Bind("LOC_LOC_ID") %>'></asp:TextBox><br /></td>
         </tr>
         <tr>
             <td align="center">Brand :</td>
             <td width="30px"><asp:TextBox ID="BrandTextBox" runat="server" Text='<%# Bind("BRAND") %>'></asp:TextBox><br /></td>
         </tr>
          <tr>
             <td align="center">CO_WK_PERC :</td>
             <td width="30px"><asp:TextBox ID="CoWkPercTextBox" runat="server" Text='<%# Bind("CO_WK_PERC") %>'></asp:TextBox><br /></td>
         </tr>
          <tr>
             <td align="center">CO_STD_PERC :</td>
             <td width="30px"><asp:TextBox ID="CoStdPercTextBox" runat="server" Text='<%# Bind("CO_STD_PERC") %>'></asp:TextBox><br /></td>
         </tr>
          <tr>
             <td align="center">INT_WK_PERC :</td>
             <td width="30px"><asp:TextBox ID="IntWkPercTextBox" runat="server" Text='<%# Bind("INT_WK_PERC") %>'></asp:TextBox><br /></td>
         </tr>
          <tr>
             <td align="center">INT_STD_PERC :</td>
             <td width="30px"><asp:TextBox ID="IntStdPercTextBox" runat="server" Text='<%# Bind("INT_STD_PERC") %>' Enabled='<%# Bind("INT_STD_PERC") %>'></asp:TextBox><br /></td>
         </tr>
         </table>
            <div class="auto-style1">
                <asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" CommandName="Insert" Text="Insert" />
                &nbsp;<asp:LinkButton ID="InsertCancelButton" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel" />
            </div>
        </InsertItemTemplate>

        <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
        <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
    </asp:FormView>

我的 SQLDataSource 是:

<asp:SqlDataSource ID="Oracle" 
        runat="server" 
        ConnectionString="<%$ ConnectionStrings:ORACLE_IISUSER %>" 
        DeleteCommand="DELETE FROM &quot;RGP_PLAN_PERC_TEST_BK&quot; WHERE &quot;DATAKEY&quot; = ?" 
        InsertCommand="INSERT INTO &quot;RGP_PLAN_PERC_TEST_BK&quot; (&quot;YEAR&quot;, &quot;WEEK&quot;, &quot;BRAND&quot;, &quot;CO_WK_PERC&quot;, &quot;CO_STD_PERC&quot;, &quot;INT_WK_PERC&quot;, &quot;INT_STD_PERC&quot;, &quot;LOC_LOC_ID&quot;, &quot;DATAKEY&quot;) VALUES (:YEAR, :WEEK, :BRAND, :CO_WK_PERC, :CO_STD_PERC, :INT_WK_PERC, :INT_STD_PERC, :LOC_LOC_ID, (SELECT (MAX(DATAKEY) +1) FROM RGP_PLAN_PERC_TEST_BK) )" 
        ProviderName="<%$ ConnectionStrings:ORACLE_IISUSER.ProviderName %>" 
        SelectCommand="SELECT * FROM &quot;RGP_PLAN_PERC_TEST_BK&quot; ORDER BY &quot;YEAR&quot; DESC, &quot;WEEK&quot; DESC, &quot;LOC_LOC_ID&quot;" 
        UpdateCommand="UPDATE &quot;RGP_PLAN_PERC_TEST_BK&quot; SET &quot;YEAR&quot; = :YEAR, &quot;WEEK&quot; = :WEEK, &quot;BRAND&quot; = :BRAND, &quot;CO_WK_PERC&quot; = :CO_WK_PERC, &quot;CO_STD_PERC&quot; = :CO_STD_PERC, &quot;INT_WK_PERC&quot; = :INT_WK_PERC, &quot;INT_STD_PERC&quot; = :INT_STD_PERC, &quot;LOC_LOC_ID&quot; = :LOC_LOC_ID WHERE &quot;DATAKEY&quot; = :DATAKEY" OnSelecting="Oracle_Selecting">
        <DeleteParameters>
            <asp:Parameter Name="DATAKEY" Type="Decimal" />
        </DeleteParameters>
        <InsertParameters>
            <asp:Parameter Name="YEAR" Type="String" />
            <asp:Parameter Name="WEEK" Type="String" />
            <asp:Parameter Name="BRAND" Type="String" />
            <asp:Parameter Name="CO_WK_PERC" Type="Decimal" />
            <asp:Parameter Name="CO_STD_PERC" Type="Decimal" />
            <asp:Parameter Name="INT_WK_PERC" Type="Decimal" />
            <asp:Parameter Name="INT_STD_PERC" Type="Decimal" />
            <asp:Parameter Name="LOC_LOC_ID" Type="String" />
            <asp:Parameter Name="DATAKEY" Type="Decimal" />
        </InsertParameters>
        <UpdateParameters>
            <asp:Parameter Name="YEAR" Type="String" />
            <asp:Parameter Name="WEEK" Type="String" />
            <asp:Parameter Name="BRAND" Type="String" />
            <asp:Parameter Name="CO_WK_PERC" Type="Decimal" />
            <asp:Parameter Name="CO_STD_PERC" Type="Decimal" />
            <asp:Parameter Name="INT_WK_PERC" Type="Decimal" />
            <asp:Parameter Name="INT_STD_PERC" Type="Decimal" />
            <asp:Parameter Name="LOC_LOC_ID" Type="String" />
            <asp:Parameter Name="DATAKEY" Type="Decimal" />
        </UpdateParameters>
    </asp:SqlDataSource>

不知道是不是因为我没有正确关联FormView的参数？

我希望有人能阐明我的问题吗？

亲切的问候

ORA-01006 : bind variable does not exist 错误意味着在你的代码中某处正在构建参数化的 SQL 语句，但是你调用该语句你没有传递足够或传递给很多参数。

仔细看，我可以看到你的

DeleteCommand="DELETE FROM "RGP_PLAN_PERC_TEST_BK" WHERE "DATAKEY" = ?" 

没有参数
它应该看起来像:

DeleteCommand="DELETE FROM "RGP_PLAN_PERC_TEST_BK" WHERE "DATAKEY" = :DATAKEY" 

Oracle documentation :

A program issued a BIND call for a variable not listed in the associated SQL statement. Only those variables prefixed by either a colon (:) or ampersand (&) in the SQL statement may be referenced in a BIND call, OBIND or OBINDN. This error may also be caused by a mismatch between a Precompiler program and the related library, SQLLIB.
