问题描述
更新记录时,某些 DateTime
值可能类似于 2015-06-25T01:35:52Z
或 13 jun 2014
When updating records some DateTime
values may look like 2015-06-25T01:35:52Z
or 13 jun 2014
所以当我写查询时:
Dim Query As String = "Update Activities set ActivityDate = '" & theDate & "' where customerid = 10"
(使用 vb.net)
(using vb.net)
但会导致错误.我可以使用 DateTime
转换吗?
but results in error. Is there a DateTime
conversion I can use?
推荐答案
Using Data.SqlClient.SqlCommand.Parameters.Add
:
MSDN:SqlCommand.Parameters 属性
参数化查询可以为您处理此日期时间转换:
A parameterized query can handle this datetime conversion for you:
Protected Sub UpdateCustomerActivityDate(customerID As Integer, activityDate As DateTime)
Dim sql As String = "Update Activities set ActivityDate = @activityDate where customerid = @customerID"
Dim cmd As New Data.SqlClient.SqlCommand(sql)
cmd.CommandType = CommandType.Text
cmd.Parameters.Add("@customerID ", Data.SqlDbType.Int).Value = customerID
cmd.Parameters.Add("@activityDate ", Data.SqlDbType.DateTime).Value = activityDate
Try
Using connection As New SqlConnection(YourConnectionString)
connection.Open()
cmd.Connection = connection
cmd.ExecuteNonQuery()
End Using
Catch ex As Exception
Throw ex
End Try
End Sub
