Hi,

I have a xml like this.

<DocumentElement>
<tLockhistory>
<lockrequesteddate>2012-12-14T00:00:00+05:30</lockrequesteddate>
<lockexpirydate>2012-12-29T00:00:00+05:30</lockexpirydate>
<createddate>2012-12-14T00:00:00+05:30</createddate>
</tLockhistory>
<tLockhistory>
<lockrequesteddate>2012-12-14 00:00:00</lockrequesteddate>
<lockexpirydate>2012-12-29 00:00:00</lockexpirydate>
<createddate>2012-12-14 00:00:00</createddate>
</tLockhistory>
</DocumentElement>

output is this.

lockrequesteddate lockexpirydate
----------------------- -----------------------
2012-12-13 18:30:00.000 2012-12-28 18:30:00.000
2012-12-14 00:00:00.000 2012-12-29 00:00:00.000

Note:
first row is the one really passed from the XML,
second row was added by me to check where is the issue.

My Question is:
How can I handle the XML date values, where the system reads a date value as a value which actually one day previous to the given date.

any immediate suggestion would be a great help to me.

Thanks in advance.

The first time above is in UTC time. It is the time on the system expressed with an offset. If you add the offset to the time displayed (2012-12-13 18:30:00.000 + 5:30) that will be 2012-12-14 00:00:00.000.

Other than that, I can't be much help as I am learning XML and XML processing myself.

Gosh... it would really be nice if I could actually read this. Would you mind replying in English, please?

Hello

In a SQL to get the fields of XML to SQL query would be like this, not if you really want to take SQL.


select
campo.value('(/Encabezado/Heads_tree_XML)[1]','Data_type'')
from tabla

I hope to help you

As you don't mention exactly what you are trying to achieve, it is hard to give a definite answer, but my guess from your desire to see the date as the 14th, not the 13th is that you want to show it as local time for the +05:30 time zone, in which case, just ignore the timezone...


declare @xml xml ='<DocumentElement>
<tLockhistory>
<lockrequesteddate>2012-12-14T00:00:00+05:30</lockrequesteddate>
<lockexpirydate>2012-12-29T00:00:00+05:30</lockexpirydate>
<createddate>2012-12-14T00:00:00+05:30</createddate>
</tLockhistory>
<tLockhistory>
<lockrequesteddate>2012-12-14 00:00:00</lockrequesteddate>
<lockexpirydate>2012-12-29 00:00:00</lockexpirydate>
<createddate>2012-12-14 00:00:00</createddate>
</tLockhistory>
</DocumentElement> '

-- selecting the value as CHAR(19) will take the date and time, but drop the timezone information, giving you the "local" time.
select cast(nd.value('(./lockrequesteddate/text())[1]','char(19)') as datetime) as lockrequesteddate
from @xml.nodes('/DocumentElement/tLockhistory') as x(nd)
