I learn the follow commands to backup and restore of SQL Server:

backup database northwind to disk = 'c:\northwind.bak'
restore database northwind from disk = 'c:\northwind.bak'

Ok, but my database is in server of my ISP... How I do to perform backups and restores? I need contact them? Confused | :confused:

And how I do to download the backups???

Thanks for all by the help.

I suggest contacting them. Remember that the path you specify in the BACKUP DATABASE command is relative to the database server machine, i.e. the above command will backup to the root of the server's c: drive.

If you don't specify a path, the backups will go to the server's default backup directory.

Inserting Soap formatted XML into SQLServer2K table

Hi :
I am a starter in .NET technology and just trying to save this soap formatted XML serialized from Account class, mentioned below.
========================================================
<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:clr="http://schemas.microsoft.com/soap/encoding/clr/1.0" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<a1:Account id="ref-1" xmlns:a1="http://schemas.microsoft.com/clr/nsassem/Accounts/Accounts%2C%20Version%3D0.0.0.0%2C%20Culture%3Dneutral%2C%20PublicKeyToken%3Dnull">
<Name id="ref-3">Atanu</Name>
<Balance>500</Balance>
</a1:Account>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
==========================================================
Account table in SQLServer2K, has 2 fields: Name & Balance and currently has no data. When trying to insert using usual method (DataAdapter, CommandBuilder, DataSet), it is inserting NULL in the Name col and 500 in the Balance column.
Then I removed the (id="ref-3") from (<Name id="ref-3">Atanu</Name>) of the above generated XML and now the value "Atanu" is correctly inserted in the Name col? But then I should not have done this.
Could you please tell me how to insert the above XML into Account table. Also could you please tell meaning of the phrase "<Name id="ref-3">Atanu</Name>" found in the above XML, generated using serialize method and soap-formatter - I mean meaning of "id=ref-3" attrb. in the name element and is there any way to get rid of the attrb. while the XML was generated.

Thanks very much.
Atanu

What is your code? You don't need to insert the whole XML, SQLServer 2000 can do it for you and return results from a table in a XML format. For start point see sp_xml_preparedocument in SQLServer Online Book to see how to insert XML file ito your database.

hello,
i am in need of ODBC(C++) code that performs join (natural or inner) between 2 tables based on some condition.But i dont know where to look for. Can someone please give me some pointers or source.
(this is not my assignment!! i need to it for someother purpose and unfortunately i dont have time to learn ODBC c++ interfaces).
thanks a lot

I'm not sure the ODBC library has this feature. Normally you join tables using SQL, in the statement that you pass to SQLExecDirect or SQLPrepare, or within a stored procedure (which you call using a suitable {call=procname} syntax with either of the above functions).

Locale of DataSet effects datetime values?

Hi, gurus

I have a web method, getting DataSet with locale property set to "en-GB". My local settings are different. DataSet has columns of datetime type and I was suprised that when I get data using

DataSet myDS = goToWebMethod(...);
and
Inserting data into local DB from myDS as is

I've got permanent 6 hr difference in time !
Any ideas?

That's nice, but it modifies the data!!!
This action is taken without asking, on the background. And what if I don't care about this fantastic feature? I just want to get what was sent to me, as is.
This looks ridiculous, don't you agree?

CRecordSet and CDatabase.ExecuteSQL

18-Mar-04 5:21

Hello all.. i need your help again.
I'm use CDatabase and CRecordSet to access to my access database.

forexample myTable have two rows, row1 and row2. row1 contains texts, row2 contain numbers
as shown below.

r1 | r2
___________
a | 1
a | 1
b | 2
c | 1
a | 1
c | 5
d | 5
d | 9
a | 3

I want only a,b,c,d from row1 not entire column, so I wrote the following code to get select the data that I want. but it still giving me entire column instead of only a,b,c,d
could you please point me out that what am i doing wrong?

<br />
CDatabase db;<br />
MyCRecordSet rs(&db);<br />
db.open.....<br />
rs.open...<br />
<br />
//some more code here then<br />
CString qstr = "SELECT DISTINCTROW r1 FROM myTable";<br />
rs.m_pDatabase->ExecuteSQL(qstr);<br />
if(rs.ReQuery())<br />
{<br />
  while(!rs.isEOF())<br />
  {<br />
    MessageBox(rs.rOneData);<br />
  }<br />
}<br />
<br />

thank you

I think you meant myTable have two Columns, r1 and r2
and you want one row for each unique value in column r1
"select distinct" will do that. select distinctrow retuns all the rows that are not duplicates (all column vaues equal).

yes.. i meant myTable have two columns, r1 and r2
i think i have to use distinctrow, since you said that
distinctrow returns all the rows that are not duplicates meaning
if i use distinctrow i will get a,b,c,d from r1 as I wanted.

anyway i tried both and it is not giving me the answer i wanted.

<br />
CString qstr = "select distinctrow r1 from myTable";<br />
rs.m_pDatabase->ExecuteSQL(qstr);<br />
if(rs.ReQuery())<br />
{ <br />
while(!rs.IsEOF())<br />
{<br />
 MessageBox(rs.r1Data);<br />
 rs.MoveNext();<br />
}<br />
}<br />
<br />

keeping giving me entire r1 column data.
is it because of rs.IsEOF() while loop??
is is CRecordSet will have the record of whatever record set of sql query statement executed and return??

The DISTINCTROW only eliminates duplicate records from the query result; it does nothing to qualify the selection. You need to include a WHERE clause in the query to define what records you want returned. Adding the clause WHERE r1 >= 'a' AND r1 <= 'd' (or whatever is syntactically correct for Access) will filter the resulting recordset so that it contains only records that meet the specified criteria. Also, specifying r1 as the only value returned is probably not what you intend - try SELECTing * to return entire records.

ExecuteSQL lets you send SQL-Commands to the Database directly, but it doesn't change the recordset (you can prove by examining the m_strSQL member)

to use aggregate functions and the like (sum, count, distinct, ...) you have to modify the DopFieldExchange-function:

void
CDPDCount::DoFieldExchange(CFieldExchange* pFX)
{
pFX->SetFieldType(CFieldExchange::outputColumn);
RFX_Long(pFX, _T("COUNT(*)"), m_lCount);
}

hope it helps Smile | :)

Mapping SqlParamters to Computed Columns

How can a sql paramter in a sql command be mapped to a coputed column in a data table?

Thanks In Advance

First up, you can't set a computed column's value (unless, I think, you write an INSTEAD OF trigger).

If you want to set an output parameter, you need to set it in the body of your statement. I normally do this from a stored procedure - I'm not sure that you can use output parameters with a literal SQL statement.
