Backup SQL 2005 Database Using Code
Jun 21, 2010I have designing a desktop application with SQL SERVER 2005. I have one form where user can take a full backup of SQL Database in one File.
I have following controls :
1. txtSQLServerName
2. txtSQLDBName
3. txtSQLSQUserID
4. txtSQLSAPassword
5. txtBackupLocation
6. btnStart
7. btnCancel
When user process the backup, it should take a backup in specified location. The backup file should be like "BKP_F_YYYYMMDDHHMMSEC" e.g. "BKP_F_20100406131523.BAK" (where 2010 = Year, 04 = Month, 06 = Date, 13 = HOur, 15 = Minute, 23 = Second). When user process a backup on next day the backup file name should be same as the above with the different date and time. And i want this backup should be encrypted with password so that other person cannot restore my database.

Sql - Copying A Table From One Database Into A Database On A Different Connection (ADO.NET)
Jun 17, 2011I am trying to copy a table in a database into another database on another connection in VB.NET, using OleDb. If they were on the same connection I would just use SELECT INTO, but they are not. I have two different OleDbConnection and cannot see an easy way to do this.
Right now I am attempting to just copy the database into a DataTable using an OleDbDataAdapter, and then loop through the DataTable and insert every record into the target database one at a time. This obviously takes a ton of time for the large DB I could potentially be dealing with, and I have to deal with escaping strings, null values, etc.
edit - just to make this more clear: I have two OleDbConnection objects, one is linked directly to a local .mdb file on my computer (JET). The other is linked to a database on our servers (SQLOLEDB). I am wanting to do this:
"SELECT * FROM fromDB INTO toDB"
But I can't because fromDB and toDB are on different connections, and the OleDbCommand object is only attached to one. The only way I can see how to do this is to connect to fromDB, copy it into a DataTable, connect to toDB, and copy all of the data in the DataTable row by row into toDB. I was wondering if there is an easier way to do this.

VS 2005 - Odd Occurrence With SQL Connection
Apr 17, 2010I have a an application that opens a SQL connection and over the course of a few hours creates and disposes of tens of thousands of DataReader objects. You could look at it as just one big loop. As the time goes by, the memory usage steadily climbs until the application/system runs out of memory and crashes.
Psuedo code would look something like
SQLConnection.Connect
Do Until x =1000000
Create New DataReader
Use DataReader
Close DataReader
[Code] .....
Even though I dispose of the DataReader object when I am done with it, the memory usage keeps climbing. I found that every time I am finished with the DataReader I have to close the SQLConnection and dispose of it. When I do that it keeps the memory usage very low and the processor usage is barely noticeable. I would think I could just open the SQL connection once and close it when I am done.
