无法将excel工作表数据更新到sql server数据库

Question

我们有一个 sql server 2008 R2 支持的 asp.net 应用程序。 可以选择从 Excel 工作表更新或插入数据库中的条目。选择要上传的文件后，当我单击更新按钮时，页面会刷新，没有其他任何反应。数据库不会更新。 我尝试调试代码，令我惊讶的是，它运行良好！尝试了很多次，同样的事情发生了。不会从应用程序更新，但会在调试时更新！我知道发布代码将帮助人们更好地理解问题，但不允许根据我组织的政策发布任何代码。我很抱歉。 非常感谢任何帮助！

 I think in code u mentioned the Sheet name wrong so that it can't be inserted.

may this code helps u..

string excelConnectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=Excel 8.0", path);
                OleDbConnection connection = new OleDbConnection();
                connection.ConnectionString = excelConnectionString;
                string qry = "write query here "' from [Sheet1$]";
                OleDbCommand command = new OleDbCommand(qry, connection);
                if (connection.State == ConnectionState.Closed)
                {
                    connection.Open();
                }
                DbDataReader dr = command.ExecuteReader();
            string sqlConnectionString = @"Data Source=A115-PC;Initial Catalog=ErpDB;User ID=sa;Password=XYZ@123";
            // Bulk Copy to SQL Server 
            SqlBulkCopy bulkInsert = new SqlBulkCopy(sqlConnectionString);
            bulkInsert.DestinationTableName = "MTPractiBilling"; // table name
            bulkInsert.WriteToServer(dr);

            DataSet dsClient = new DataSet();
            dsClient = ccSql.pBindDataSet("Select Path,FileSize,DocumentName from MTPractiBilling where UploadName='" + uploadnm + "'");
            if (dsClient.Tables[0].Rows.Count > 0)
            {
                for (int i = 0; i <= dsClient.Tables[0].Rows.Count; i++)
                {
                    clpath = dsClient.Tables[0].Rows[i][0].ToString();

                    FSize = dsClient.Tables[0].Rows[i][1].ToString();
                    DocNm = dsClient.Tables[0].Rows[i][2].ToString();
                    string s = clpath;
                    string[] words = s.Split('\\');
                    clpath = words[4];
                    scpath = words[4];
                    clpath = ccSql.pReturnSingleValue “ personal query'");
                    scpath = ccSql.pReturnSingleValue("personal query' "");
                    int cnt = ccSql.pReturnIntegerValue("personal query'"'");
                    //int match = ccSql.pReturnInteger("personal query'");
                    if (cnt <= 0)
                    {
                        ccSql.pExecuteQuery("personal query''");

                    }
                    else
                    {
                        ccSql.pExecuteQuery("personal query''");
                        Label1.Text = DocNm.ToString() + "-" + FSize.ToString() + " Already Billed or Process..";
                        return;
                    }
                }
