Question

我试图从javascript中插入/更新postgis数据库中的时间戳，但它不起作用。我在postgis中有Timestamp列，时间戳没有时区数据类型。

 //My Javascript function is
   function save(){
       var cTime = get
       WebService.saveData('Test', cTime);
   } 

   function getTimeStamp() {
    var cDate = new Date();
    var sChar = String.fromCharCode(39);
    var timeStamp = sChar + cDate.getFullYear() + '-' + (cDate.getMonth() + 1) + '-' + cDate.getDate() + ' ' + cDate.getHours() + ':' + cDate.getMinutes() + ':' + cDate.getSeconds() + '.' + cDate.getMilliseconds() + sChar;
    //alert(timeStamp); //'2013-11-5 17:12:15.242'
   return timeStamp;
 }

   //My webservice function is:
    <WebMethod(enablesession:=True)> _

   Public Function saveData( ByVal name As String,byval cTime as  string) As String
      try

        Dim qryStr As String = "INSERT INTO ODC_Private_Graphics_Data (the_geom,timestamp)  VALUES ("' & name & "'," & cTime & ")"
        dbObj.Connect()
        Dim insertCmd As NpgsqlCommand = New NpgsqlCommand(qryStr, dbObj.dbCon)
        Dim affectedRows As Integer = insertCmd.ExecuteNonQuery
        dbObj.Disconnect()
        insertCmd.Dispose()
        insertCmd = Nothing

Catch ex As Exception

Finally
    dbObj.Disconnect()
End Try

请建议我在postgis数据库中插入时间戳的格式。提前谢谢

在SQL表达式中使用单引号，因此结果查询将为

INSERT INTO ODC_Private_Graphics_Data(the_geom,timestamp) VALUES ('Test','2013-11-5 17:12:15.242');

双引号用于PostreSQL中的列名。

如何使用javascript在没有时区列的Postgis时间戳中插入当前时间戳？
