小编Alf*_*ima的帖子

In my database 1 is used to represent true and 0 to represent false. In my column, now i was wondering if anyone can help me write a query that outputs if the value equals to 1 display true if equals to 0 display false?.

我有一个返回信息的数据表方法,但我的参数有问题,它一直抛出一个必须声明变量'@SUPartnerNo'错误.我试图谷歌,但我找到的解决方案都没有帮助.我不想将我的参数直接嵌入到我的查询中,因为它不是很好的做法

public DataTable SearchInvoiceHeader(string SUPartnerNo, string invoiceNo, string bdate, string edate)
{
    DataTable dt = new DataTable();

    try
    {
        StringBuilder mySelectQuery = new StringBuilder(9000);


        mySelectQuery.AppendLine(@"SELECT I.[InvoiceNo]
                                    ,I.[SUPartnerNo]
                                    ,I.[OrderNo]
                                    ,I.[RefNo]

                                    ,I.[SAP_Type]
                                    ,I.[SUName]
                                    ,I.[InvoiceDate]
                                    ,I.[PaymentDate]
                                    ,I.[BaseLineDate]
                                    ,I.[DeliveryDate]
                                    ,I.[DeliveryNoteNo]
                                    ,I.[TotalAmount]
                                    ,I.[StartTime]

                                    ,s.TotalValue
                                FROM [dbo].[mainhead] I WITH (NOLOCK) 
                                LEFT JOIN [INV_Processed] p WITH (NOLOCK) 
                                ON p.InvoiceNo = I.InvoiceNo
                                AND p.PartnerNo = I.SUPartnerNo

我正在通过linq搜索姓名和姓氏,我想将结果绑定到转发器.

我究竟做错了什么？

// this the results for list

public static List<SearchResults> lsSearchResults = new List<SearchResults>();

public class SearchResults
        {
            public string Name { get; set; }
            public string Surname { get; set; }

            public SearchResults(string name, string surname)
            {
                Name = name;
                Surname = surname;
            }

        }

// search button
protected void btnSearch_Click(object sender, EventArgs e)
        {
