Saving Changes Made To Database
Jul 20, 2005
I have an application that connects and edits a database's tables.
My question is, what is the best way to save who did what changes to
this database? I need to be able to display this in the application.
The best way I have thought of so far is, to create a new table with
'user', 'date', 'table_name', 'primary_key', 'old field_value' and
'new_field_value' fields. Then I can save which table row had been
changed, by which user and on which date.
I'm sure that there is a way to do this in SQL Server, but I'm not
sure how.
Any help would be appriciated.

Here is the situation. I have an employee who is making changes but I can't prove it. He thinks he knows more than he does and he's mess'n everything up. I would like to know if SQL or some third party product has the capability to see the change and log what was changed with the persons username attached?

Looks like I'm up to no good as usual.
Basically due to a client spec, I had to create 115 datasets (one for each of my 115 tables).
After I created the 111th, I am getting the following error:
A connection cannot be made to the database. Timeout Expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
How do I clear the pooled connections or increase the max pool size?
I suppose what happened is each time I create a dataset it opens a connection to the database and these connections aren't being terminated...

I am very new to SSAS. I have two queries:
1) As per my project requirement, if the changes in SSAS cube are approved, they should be committed back to the actual SQL Server 2012 tables. Is that possible, if yes how?
2) For rolling back to original data I truncate the relevant writeback table and process the cube.

Hi all,
Can anyone give me a ready-made sample script to display a search reslut from a database?
My intention is to give a dynamic web page for the search in the BookStore website.
The result will show the following:-
First the picture of the book.
To the right of it, 'Title' field, below that, 'description' field
It should be created programatically as the contents are in the database.
I tried several ways, but could not succeed. I have the BookID, Title, BookPicture, and the Description fields
Thanking you in advance,
Tomy

Hi Guys,
I am trying to automate a basic task using SQL Server 2005 Express.
Currently I have a query script that I run and then save the results as a CSV file. I need to do this on a daily basis and so I am looking to find out how best to go about this. There are a multitude of third party tools that claim to be able to do this - can anyone recommend this or enlighten me of the best way to set up this automation.
All ideas gratefully received!

My install of SQL Server 2005 runs like a dog. The SQL Management Studio splash screen lasts for 10 minutes, then when the Studio window appears it takes another 5 minutes to initialize.
I have SQL server installed on a Germane Server running Windows Server 2K, SP4. It has quad Xeon 2.8 GHz processors with 2GB RAM. 4 300GB drives in a RAID 5 configuration.
I have created 2 databases which I would like to save, uninstall SQL, then reinstall it. (I didn't install it the first time.)
Then load the 2 databases into the new install.
How do I do this?

I have 3 strings delimitted by a * character that I would like to save to a database. Each string will always have the same number of elements.
strUserID = "1*2*3"
strCompanyID="12931*12937*12945"
strCompanyName="International Business Machines, Inc*Ford Motor Company*Delta Airlines"
What I need to do is to save each record like this
INSERT INTO tableA (UserID, CompanyID, CompanyName) VALUES (1, 12931, 'International Business Machines, Inc')
INSERT INTO tableA (UserID, CompanyID, CompanyName) VALUES (2, 12937, 'Ford Motor Company')
INSERT INTO tableA (UserID, CompanyID, CompanyName) VALUES (3, 12945, 'Delta Airlines')
I've done something like this before with a single string, but don't know how to handle 3 of them.
Dim strAlerts As String() = NothingstrAlerts = values.Split(",")Dim s As String For Each s In strAlerts SqlText = "INSERT INTO tableA (UserID, CompanyID, CompanyName) VALUES (" & lblUserID.Text & ", '" & lblCompanyID.Text & "','" & s & "')" cmd = New SqlCommand(SqlText, strSQLConn) cmd.ExecuteNonQuery() Next s
Thanks for any help

Hi there,
I have a web page (Visual Studio 2005, Asp.net 2.0) that has a series of textboxes and dropdownlists on it. I want people to be able to enter their information and click submit. When they click the submit button I want their information to save to a Sql Server 2005 database. I am having a lot of trouble finding any information on this topic. If someone could give me some sample code I would really appreciate it.
Thanks

I'm using vs2008 programming in the latest vb.net and am pretty new to sql server. I looked up tuts and such to save changes to databases after I understood on how to connect to them get them to display and such. This is my code when I hit the "Save" button. It worked last time I was working on the program, now it doesn't, when I load up the program sometimes (i'm not sure why or under what circumstances) it'll load up the changes I made to the database through the datagrid and saved, but others it won't. What am I doing wrong? Here's my code:
Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click
Try
Me.Validate()
Me.FinancialBindingSource.EndEdit()
Me.FinancialTableAdapter.Update(Me.myDataSet.Financial)
Catch ex As Exception
MsgBox("Update failed")
End Try
End Sub
edit: It saves, but not completely. By that I mean, it'll save, but i'm not sure if it actually saves to the database or not. It will load back up with the data that I modified fine..unless I change any code in the program. Even if I just add a comment, the data reloads with the original data. However, if I don't touch code, it'll save my data fine. Why does it do this?

Hi all,
I have a replicated table with a column which is used to store sound files - it is of type varbinary(MAX).
What is the best way to store a file from the filesystem inside this column on the PDA side (i.e. inside SQL Server CE) without loading the whole file into the PDA's memory, i.e. using some sort of buffering?
On full SQL Server 2005 I make use of UPDATE.WRITE() to save buffers inside the column - is there an alternative to this on SQL Server CE? Can anyone provide sample code / point me to samples that deal with SQL Server CE & BLOBs.
Thanks for your help!

Hi,Using VB.net I have created a custom object (hope my terminology is correct here), it’s just a class that defines a few string, integer, and hash table variables. After creating an instance of this class and populating it with data I need to be able to store this instance of my object in a sql server data base table. How do I do this? I saw an article that used the image data type to achieve this (code was in java unfortunately) is this the correct approach. Could you please give me some code examples
Thanks

I am brand new to SQL. Have limited coding experience w/ Visual Basic and database ops w/ Access.
I have come into possession of a SQL 2005 database. The problem is that the designer tried to re-invent the wheel and code a very very poor LMS back end for tracking and reporting. I would like, if possible, to save the database and as far as I am aware - should be able to import into Access and generate statistics and reports to my hearts content.
I have tried w/out success to save the database going through SQL Server Management Studio Express.
Any help or information that could be provided would be appreciated. Any additional information that I can provide, please let me know.
Thanks - Will
