我正在使用SQL Server数据库,并选择记录来显示合同信息。协议可以是活动的,不活动的,等待响应或等待付款。
我的用户希望网格按此顺序显示结果:
我尝试使用以下代码来实现此目的,但它会在默认字词附近引发错误,说明语法错误。
按声明排序有什么问题?
Try
sql = "SELECT ContractID, CustAcc, DateStart, DateRenew, Fee, Agreement, OtherDetails, " _
& "DateSent, TimeSent, ReminderName, ReminderEmail FROM dbo.tblContracts " _
& "ORDER BY FIELD(Agreement, 'AWAITING RESPONSE', 'AWAITING PAYMENT', 'ACTIVE', 'INACTIVE')"
conAd = New OleDb.OleDbDataAdapter(sql, con)
conset = New DataSet
conAd.Fill(conset)
ugModules.DataSource = conset
Catch ex As Exception
errorLog(ex.Message, ex.StackTrace)
MsgBox("Failed to retrieve contract information, refer to error log")
End Try
编辑
按照@Solarflare的建议改变我的代码后,我现在得到了以下代码;
sql = "SELECT ContractID, CustAcc, DateStart, DateRenew, Fee, Agreement, OtherDetails, " _
& "DateSent, TimeSent, ReminderName, ReminderEmail FROM dbo.tblContracts " _
& "ORDER BY CASE Agreement WHEN 'AWAITING RESPONSE' THEN 1 WHEN 'AWAITING PAYMENT' THEN 2 " _
& "WHEN 'OVERDUE' THEN 3 WHEN 'ACTIVE' THEN 4 WHEN 'INACTIVE' THEN 5 END"
所以INACTIVE主要位于顶部,其次是AWAITING RESPONSE和INACTIVE等 - 为什么会这样?
答案 0 :(得分:0)
ORDER BY应该在SQL Server中使用CASE语句。
