如何将“字符串”转换为“无时区时间戳”

I am new to Postgresql and I am using WCF services.
Here is my code snippet:

我是Postgresql的新手，我正在使用WCF服务。下面是我的代码片段:

$.ajax({
    url: '../Services/AuctionEntryServices.svc/InsertAuctionDetails',
    data: JSON.stringify({ "objAuctionEntryEntity": {
        "AuctionNO": '',          
        "AuctionDate": $('[Id$="lblAuctionDateVal"]').text(),
        "TraderID": $('[Id$="ddlTraderName"] option:selected').val(),
        "Grade": $('[Id$="ddlGrade"] option:selected').val(),
        "Varity": $('[Id$="ddlVarity"] option:selected').val(), 
        "QuntityInAuction": $('#txtQuantityForAuction').val(),
        "AuctionRate": $('#txtAuctionRate').val(),
        "BrokerID": a[0],
        "IsSold": $('#chlIsSold').is(':checked'),
        "CreatedBy": $.parseJSON(GetCookie('Admin_User_In_Mandi')).UserID,
        "UpdatedBy": $.parseJSON(GetCookie('Admin_User_In_Mandi')).UserID,
        "CreationDate": GetCurrentDate().toMSJSON(),
        "IsActive": true,
        "AuctionTransaction": arrAuctionTransaction,
        "MandiID": $.parseJSON(GetCookie('Admin_User_In_Mandi')).MandiID,
        "FarmerID": _ownerid,
        "AuctionNO": _auctionno,
        "AmmanatPattiID": _ammantpattiid,
        "ToTraderID": b[0],
        "ToTraderName": $('#txtOtherBuyerNameEN').val(),
        "ToTraderName_HI": $('#txtOtherBuyerNameHI').val()
    }
}),
    type: 'POST',
    contentType: 'application/json',
    dataType: 'json'              
});

Here:

在这里:

$('[Id$="lblAuctionDateVal"]').text() = "20/8/2013 14:52:49"

And my data type for this field is timestamp without time zone.
How to convert this string to timestamp without time zone data type?

这个字段的数据类型是没有时区的时间戳。如何将该字符串转换为没有时区数据类型的时间戳?

2 个解决方案

String representation of a timestamp (= timestamp without time zone) depends on your locale settings. Therefore, to avoid ambiguities leading to data erros or Postgres coughing up an exception, you have two options:

时间戳的字符串表示形式(=没有时区的时间戳)取决于您的语言环境设置。因此，为了避免导致数据erros或Postgres出现异常的歧义，您有两个选择:

1.) Use ISO 8601 format, which works the same with any locale or DateStyle setting:

1)。使用ISO 8601格式，适用于任何地区或日期设置:

'2013-08-20 14:52:49'

You may still have to cast the string explicitly where the data type is no known a priori, depending on the use case:

您可能仍然需要在数据类型未知的情况下显式地转换字符串，具体取决于用例:

'2013-08-20 14:52:49'::timestamp

2.) Convert your string to timestamp using to_timestamp() with a matching template pattern:

2)。使用to_timestamp()将字符串转换为时间戳，并使用匹配的模板模式:

to_timestamp('20/8/2013 14:52:49', 'DD/MM/YYYY hh24:mi:ss')

To convert a string into a timestamp without timezone, for Postgresql, I use the above

要将字符串转换为没有时区的时间戳，对于Postgresql，我使用上面的代码

SELECT to_timestamp('23-11-1986 09:30:00', 'DD-MM-YYYY hh24:mi:ss')::timestamp without time zone;
