Question

这是gridview的 HTML 标记。我的意思是aspx页面

 <asp:GridView ID="Gridview1" runat="server" ShowFooter="true" AutoGenerateColumns="false"
    OnRowCreated="Gridview1_RowCreated" Height="145px">
    <Columns>
        <asp:BoundField DataField="RowNumber" HeaderText="Row Number" />
        <asp:TemplateField HeaderText="Header 1">
            <ItemTemplate>
                <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Header 2">
            <ItemTemplate>
                <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Header 3">
            <ItemTemplate>
                <asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true" DataTextField="CURRENCY_NAME"
                    DataValueField="CURRENCY_ID">
                </asp:DropDownList>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="Header 4">
            <ItemTemplate>
                <asp:DropDownList ID="DropDownList2" runat="server" AppendDataBoundItems="true" DataTextField="BRAND_NAME"
                    DataValueField="BRAND_ID">
                </asp:DropDownList>
            </ItemTemplate>
            <FooterStyle HorizontalAlign="Right" />
            <FooterTemplate>
                <asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" OnClick="ButtonAdd_Click" />
            </FooterTemplate>
        </asp:TemplateField>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">Remove</asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>
<asp:Button ID="BtnSave" runat="server" Text="Save All" OnClick="BtnSave_Click" />
<asp:Label ID="lblMessage" runat="server" Text=""></asp:Label>`

以下是将数据保存到数据库中的代码

private void InsertRecords(StringCollection sc)
    {
        StringBuilder sb = new StringBuilder(string.Empty);
        string[] splitItems = null;
        const string sqlStatement = "INSERT INTO GridViewDynamicData (Field1,Field2,Field3,Field4) VALUES";
        foreach (string item in sc)
        {
            if (item.Contains(","))
            {
                splitItems = item.Split(",".ToCharArray());
                sb.AppendFormat("{0}('{1}','{2}','{3}','{4}'); ", sqlStatement, splitItems[0], splitItems[1], splitItems[2], splitItems[3]);
            }
        }

        using (OracleConnection strConn = GetConnection())
        {

                strConn.Open();
                OracleCommand cmd = new OracleCommand(sb.ToString(), strConn);

                cmd.CommandType = CommandType.Text;
                cmd.ExecuteNonQuery();


                lblMessage.Text = "Records successfully saved!";


        }
    }

    protected void BtnSave_Click(object sender, EventArgs e)
    {
        int rowIndex = 0;
        StringCollection sc = new StringCollection();
        if (ViewState["CurrentTable"] != null)
        {
            DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
            if (dtCurrentTable.Rows.Count > 0)
            {
                for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
                {
                    //extract the TextBox values  
                    TextBox box1 = (TextBox)Gridview1.Rows[rowIndex].Cells[1].FindControl("TextBox1");
                    TextBox box2 = (TextBox)Gridview1.Rows[rowIndex].Cells[2].FindControl("TextBox2");
                    DropDownList ddl1 = (DropDownList)Gridview1.Rows[rowIndex].Cells[3].FindControl("DropDownList1");
                    DropDownList ddl2 = (DropDownList)Gridview1.Rows[rowIndex].Cells[4].FindControl("DropDownList2");
                    //get the values from TextBox and DropDownList  
                    //then add it to the collections with a comma "," as the delimited values  
                    sc.Add(string.Format("{0},{1},{2},{3}", box1.Text, box2.Text, ddl1.SelectedItem.Text, ddl2.SelectedItem.Text));
                    rowIndex++;
                }
                //Call the method for executing inserts  
                InsertRecords(sc);
            }
        }   
    }

我的数据库表在这里

CREATE TABLE ERP.GRIDVIEWDYNAMICDATA
(
  FIELD1  VARCHAR2(500 BYTE),
  FIELD2  VARCHAR2(500 BYTE),
  FIELD3  VARCHAR2(500 BYTE),
  FIELD4  VARCHAR2(500 BYTE)
)

当我运行此项目时，它显示错误＆＃34; ORA-00911：无效字符＆＃34; 。我不知道出了什么问题。任何帮助将不胜感激。

我没有足够的声誉来评论，所以我发布我的研究作为答案。

最可能的原因是在查询构建中使用;。

从SQL字符串的末尾删除;（分号）。从您使用代码构建的SQL查询。

使用分号（可能导致错误）

sb.AppendFormat("{0}('{1}','{2}','{3}','{4}'); ", sqlStatement, splitItems[0], splitItems[1], splitItems[2], splitItems[3]);

没有分号（应该试试这个）

sb.AppendFormat("{0}('{1}','{2}','{3}','{4}') ", sqlStatement, splitItems[0], splitItems[1], splitItems[2], splitItems[3]);

或者

您的字符串可能没有直接'单引号。再试一次。（虽然在你的代码中发布了问题但似乎没问题。但是在验证时没有错。）
