Hi,

How can merge two tables? the select command for the 2 tables are as follows

select groupid, staff.name[created] from groups,staff where groups.created=staff.staffid

groupid created
------ --------
1 A
2 B

select groupid,staff.name[modified] from groups,staff where groups.modified=staff.staffid

groupid modified
------- --------
1 C
2 D

i have to merge these two output as

Documentation says that connection pooling is handled by provider for OleDbConnection. If you are using SQL Server, you can use SqlConnection class, and use the Pooling, Max/Min Pool Size entries in the connection string.

Is SELECT INTO optimal to copy data?

I am writing a stored proc. Currently doing a "SELECT INTO" to copy data from one table to a new one. But eventually
a. I want to do it most optimally as the data is gonna be huge
b. Also it should be able to insert data in an existing table.

What SQL stmt/function should I use? D'Oh! | :doh:

Help!!Compacting Database MSDE/SQL

Hi Guys,

I have not known so much about the SQL Server and MSDE, so just rush to here to get help.

Can any one tell me When records are deleted, is the space immediately compacted or when is it compacted?
and Is the compacting configurable? How to set it up? Since I am using the SQL buddy

For large number of records deleted (eg. Archival), is the database compacted immediately!

Many thanks in advance! I am really appreciate your help.

SQL Server does not generally compact free space. To do so, use the Shrink feature (in T-SQL, DBCC SHRINKDATABASE).

To have this occur automatically, set the 'Auto Shrink' option. You can do this in T-SQL with ALTER DATABASE db SET AUTO_SHRINK ON. MSDE has this option turned on by default.

If Auto Shrink is set, the shrinking operation occurs when there is more than 25% free space in the file. The resulting file will have 25% space free or be the size it was when originally created, if that is larger.

Hi Mike,

Thanks very much for your reply. So the compacting is a default option which already be turned on in MSDE? How about SQL Server, the option is also turned on by default?

Is there any way I can configure this option so that it can be performed when there is 10% free space?

Many thanks for your help!!

Problems with Backup/Restore of SQL server database

I have a problem in restoring sql server database in asp.net
I have first written code for full backup and differential backup of database, it is working properly.

For full backup code is :
-----------------
-----------------
objBackUp.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Database
objBackUp.Database = "tempbakup"
objBackUp.Devices = ""
objBackUp.Files = Server.MapPath("tempbakupFull.zip")
objBackUp.MediaName = Server.MapPath("tempbakupFull.zip")
objBackUp.MediaDescription = "TempBakup Database Backup Full" & Now
-------------------
------------------

For Differential backup :
objBackUp.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Differential
objBackUp.Database = "tempbakup"
objBackUp.Devices = ""
objBackUp.Files = Server.MapPath("tempbakupDiff.zip")
objBackUp.MediaName = Server.MapPath("tempbakupDiff.zip")
objBackUp.MediaDescription = "TempBakup Database Backup Differential" & Now

But when I used wrote following code for restore databse, I got problem

"The volume on device 'c:\inetpub\wwwroot\TestApp\tempbakupfull.zip' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set."

CODE is

oRestore.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database
oRestore.Database = "TempBakUp"
oRestore.Files = Server.MapPath("tempbakupfull.zip,tempbakupdiff.zip")
oRestore.FileNumber = 1
oRestore.ReplaceDatabase = True
oRestore.LastRestore = False
oRestore.SQLRestore(srv)

oRestore.FileNumber = 2
oRestore.LastRestore = true
oRestore.SQLRestore(srv)

One solution is that u should only save DATE portion in the datetime field u can send it as
Format(dtPicker.Value,"mm-dd-yyyy")
then ur query will work fine.

Javed

What type is dtlastdate and why are you converting it? Shouldn't it already be in a datatime (or smalldatetime) format already?

crazysanker wrote:
WHERE convert(smalldatetime,dtlastdate)>= getdate()

It didn't select the row with dtlastdate as 2006-01-25 because that is before now. You asked to select rows with a dtlastdate after now.

>= Greater than or equal to: WHERE dtlastdate is greater than or equal to getdate()

The query is working correctly.

I know you can view the diagram icon, highlight it and click Cut or Copy, but if I go to another database with the same exact schema, how do I "paste" that diagram?

Thanks!

It depends on what they've sent. If it is a backup file then just restore it. If it is an actual detached database then just attach it.

What is the value of intstatus for the test row? You don't select that, but you do filter on it.

Databinding 2 Datagridviews

Hi.

I posted this on the C# forum, but probablly this is a better place.

I'm having a little trouble getting this thing to work.

I have two tables Houses and People

Every "Person" belongs to a House, but only one per house is the "OwnerOfHouse".
So I made a colum named "HouseOwner" in the "House" table, which has the PersonID. And every person has a "HouseID_FK" which tells them to which house they belog.

SO here is the thing. I'm working with ADO.NET 2.0, and using BindingSource. So I have a BindingSource that has my Houses in a nice DataGridView, and when I click on any of them, I have another DataGridView which displays the people that live there.
That works Fine.

Now, when I chose one of the inhabitants, and press a button, His ID is updated on the Houses table, and I have a reference that tells me he is the Owner. So far so good.

What I want to do is that when I choose a House in my first DataGridView, The Owner is selected automaticlly in the People DataGridView. So far I've tried everything I could thinf of, but it allways selects the first element (the first person on the list).

Thanks in advance.
