Hi,

I have a database which is being developed as the application which uses it is and so is being changed very regularley. How can I copy the database into another location on the server to back it up?

What database?

I imagine you would need to shut the database down temporarily if you want to copy it elsewhere.

DataTableMapping problem. Don't get return values

Having made an app with a type-safe dataset. In this set there are two datatables 'Contract' and 'Contract1' which are identical. When I insert a record from the second DataTable with my stored procedure into the database, it results two result-sets 'Table' and 'Table1'. This is correct, but the only not working thing is that I don't get one column ie ContractNummer. This is made read-only in the DataTable. It is filled in the database with a after-insert-trigger and returned from the insert-procedure. Why cannot I get this value? When it comes from the first DataTable 'Contract', it strangeally works fine. Al the names and the amount of names are correct. Can you tell give me a clue? Thanks very much. Here is my code for the TableMapping-section:

DataTableMapping dtm1, dtm2;
dtm1 = oDa.TableMappings.Add("Table", "Contract");
dtm2 = oDa.TableMappings.Add("Table1", "Contract1");

dtm1.ColumnMappings.Add("ContractID", "ContractID");
dtm1.ColumnMappings.Add("Contractnummer", "Contractnummer");
dtm1.ColumnMappings.Add("Titel", "Titel");
dtm1.ColumnMappings.Add("BeginDatum", "BeginDatum");
dtm1.ColumnMappings.Add("EindDatum", "EindDatum");
dtm1.ColumnMappings.Add("BUID", "BUID");
dtm1.ColumnMappings.Add("TyperingID", "TyperingID");
dtm1.ColumnMappings.Add("KlantID", "KlantID");
dtm1.ColumnMappings.Add("Omschrijving", "Omschrijving");
dtm1.ColumnMappings.Add("MantelID", "MantelID");
dtm1.ColumnMappings.Add("PDF", "PDF");

dtm2.ColumnMappings.Add("ContractID", "ContractID");
dtm2.ColumnMappings.Add("Contractnummer", "Contractnummer");
dtm2.ColumnMappings.Add("Titel", "Titel");
dtm2.ColumnMappings.Add("BeginDatum", "BeginDatum");
dtm2.ColumnMappings.Add("EindDatum", "EindDatum");
dtm2.ColumnMappings.Add("BUID", "BUID");
dtm2.ColumnMappings.Add("TyperingID", "TyperingID");
dtm2.ColumnMappings.Add("KlantID", "KlantID");
dtm2.ColumnMappings.Add("Omschrijving", "Omschrijving");
dtm2.ColumnMappings.Add("MantelID", "MantelID");
dtm2.ColumnMappings.Add("PDF", "PDF");

try
{
oDa.Update(oDs);
oTrn.Commit();

OLE DB::IDBProperties -> Connection String [solved]

Jörgen Sigvardsson20-Sep-04 8:51

20-Sep-04 8:51

Does anybody know of a good way of converting a OLE DB property set into a connection string?

[edit]I found a nice VB-centric interface called IDataSourceLocator which gives me the connection string "automagically". However, I'm still curious to know how to convert any IDBProperties -> connection string. The docs refers to ADO connection strings when describing this VB-centric interface. I don't know what implications that may have on the resulting connection string. I use raw OLEDB under the hood, and not ADO, and I really don't want to end up with connection strings which may not work.[/edit]

[solution]Just create a MSDAINITIALIZE object, query for IDataInitialize, and use GetInitializationString on your IDBProperties object. The docs says that GetInitializationString converts a data source object to a connection string. It didn't strike me that the IDBProperties interface handle I had was in fact a data source object until now. D'Oh! | :doh:

Any security check to stop Importing Data from SQL tables into EXCEL

I am storing some user IDs & passwords in a table in SQL server. Users will login into various database related applications & they can update the data there. Also, they can change their respective passwords also. But anybody can goto EXCEL and from Data (Menu) -> Import External Data -> and New Database query, and get all the information into the excel sheet.
Is there any method to stop this?

There are good security practises that you can use to make sure that sensitive data (passwords, credit card numbers) etc are either encrypted or hashed in the database, so that a query cannot be used to view the data.

See this article for an example of this technique.

Yes. Make the users log in to SQL Server using an unprivileged login - e.g. one that is a member of the public role but not a member of dbo. This is a best practice in any case. Do your password checking in a stored procedure. Grant EXEC permission for public to the stored procedure, and deny SELECT permission to the table containing the usernames and passwords.

Don't ever give out your sa password. Make it a strong one.

SQL Server's security features are pretty powerful but you have to use them. Far too many applications use sa to connect to the database. Applications and users should always be limited to only seeing the data and performing the operations you specify.

Stability. What an interesting concept. -- Chris Maunder

SELECT and NOT IN a dynamic sequence

Vadim Tabakman19-Sep-04 15:27

Hi all,

I need to be able to do a query for those values that are not in a particular field in a recordset.

So lets say I have a table with a field (indexnum) which is a text string of a hex number. eg "00034F12". That number is incremented for each record that is added. Legacy code, so I don't know why it is done this way.

What i need to do is query for all indexnum's that don't occur given a list of indexnums. Indexnums will be between 00000001 and 0x000FFFFF. These are not hardcoded, so at the time this code will be run, it maybe between 0034829F and 00349000. So some how I need something like :
SELECT indexnum from tblData NOT IN ( SELECT ... [build up a temp table or something or a sequence of number from the starting and ending nummbers I give it] )

Can this be done somehow? I need it to work on DB's like Oracle and MS Access, and I don't think Access supports stored procedure (although I don't know much about these).

Thanx

What about a simple WHERE clause on indexnum?

select indexnum
  from tblData
 where not (indexnum between @lowerBound and @higherBound)

or maybe

select indexnum
  from tblData
 where not (indexnum >= @lowerBound and indexnum <= @higherBound)

This is me being lazy and not trying it, but asking a question first Smile | :)

Given that indexnum is a text string, will this comparison work? For example :

"00000007"
"00000008"
"0000000C"

if we ran the sql query for "00000007" to "0000000C", would it return :
"00000009"
"0000000A"
"0000000B"
????

I didn't think the database would be so smart as to count in hex using text strings.
