I am try to start with SQL BROKER service,
When I lunch from sql Management studio the following query, this don't finish never.
ALTER DATATABLE dbname SET ENABLE_BROKER
Where I am mistaking ?
I am trying to execute the following query , in Management Studio. But it takes forever. Can someone tell me why is this happening? I am running the query in 'NorthWind' database.The windows account under which I am logged into WinXP (windows authentication is enabled for the SQL Server database) is the database owner for NorthWind database.
alter database NorthWind SET ENABLE_BROKER
My SQL broker was not enabled. So I ran the query >> ALTER DATABASE OperationsManager SET ENABLE_BROKER
The query has been running for several hours and is still not complete. I let it run for over 24 hours and the broker never gets enabled.
Thanks,

We have a proc that adds some fields to a few tables of ours and normally there are no issues. For one of our client databases this process is taking anywhere from 5-10 minutes to add the fields. This causes an issue where the app will timeout waiting. After plugging around and looking at the proc and trying different items i found it to only be for this one database and ONLY when there is data in the table. If i truncate the table and run the same procedure everything is fine. Tables all have same index on 4 columns and the columns being added are not indexed because of the stupid hoops we have to jump thru to pre-pivot data for our reporting package.

I am quite new to ASP.net 2.0. I have had plenty of experience using ADO.net in standard windows applications.
In my app I am opening a connection to an SQL database and I am creating a DataTable without a DataSet:
Shared m_cnADONetConnection As New System.Data.SqlClient.SqlConnection
Shared m_daDataAdapter As System.Data.SqlClient.SqlDataAdapter
Shared m_rowPosition As Integer
Shared m_dtContacts As New System.Data.DataTable
I am initializing everything and filling my DataTable when the Page first Loads if it isnt a postback.Protected Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Form1.Load
If Not Page.IsPostBack Then
m_rowPosition = 0
m_cnADONetConnection.ConnectionString = "Data Source=.SQLEXPRESS;AttachDbFilename=C:First ASP DatabaseApp_DataMyFirstDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
m_cnADONetConnection.Open()m_daDataAdapter = New System.Data.SqlClient.SqlDataAdapter("Select * From Books", m_cnADONetConnection)m_cbRefillCommand = New System.Data.SqlClient.SqlCommand
m_daDataAdapter.Fill(m_dtContacts)
Me.ShowCurrentRecord()
End IfEnd Sub
The Me.ShowCurrentRecord Sub assigns the values of the current record(row) in the DataTable via (m_rowPosition) to TextBox controls on the form:
I also have record navigation buttons on my form: << < > >> Moving me from record to record (row to row) by incrementing or decrementing m_rowPosition
All is good! I am able navigate the DataTable and the textboxes change their text properties accordingly from record to record.
The only other control on my form is a button which I'm coding its click event to save changes that I made to the current row (record) by changing the values in the textboxes then clicking save.
Here is my code:Protected Sub ButtonSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonSave.Click
If m_dtContacts.Rows.Count <> 0 Then
m_dtContacts.Rows(m_rowPosition).BeginEdit()m_dtContacts.Rows(m_rowPosition)("Title") = TBTitle.Text
m_dtContacts.Rows(m_rowPosition)("Author") = TBAuthor.Textm_dtContacts.Rows(m_rowPosition)("YearPublished") = TBYearPublished.Text
m_dtContacts.Rows(m_rowPosition)("Price") = TBPrice.Textm_dtContacts.Rows(m_rowPosition)("LastReadOn") = TBLastReadOn.Textm_dtContacts.Rows(m_rowPosition)("PageCount") = TBPageCount.Text
m_dtContacts.Rows(m_rowPosition).AcceptChanges()
m_dtContacts.Rows(m_rowPosition).EndEdit()
m_dtContacts.AcceptChanges()
m_daDataAdapter.Update(m_dtContacts)
End Sub
After I click save I can navigate through my records and back to the one I just changed and updated and all is well. The changes were made in the table.
However, when I close the page and exit out of Visual Web Developer and reopen the database: THE CHANGES WERENT UPDATED!!!
This worked all the time in VB2005.net when developing a standard windows app.
Can I use the same approach I was using in my code above or am I missing something.
I have read and searched all over and what I'm thinking is that my UpdateCommand, InsertCommand, DeleteCommand, SelectCommand are empty.
Do I have to do it this way?
Hi GuysI am facing a problem while updating a DataTable to database using sqldataadapter.In my application I am fetching a dataTable from Database and filling values into textboxes on the UI.User has given facility to change or add new texboxes (new row) on the fly .(Textboxes on the UI are like in a row(tr) having two textboxes in each row.)I am again then converting a new (empty) datatable from scrap and filling its rows with the value of textboxes on submit button event.The datatable which I have created has the same schema as the database table.Now what I want here is that changed value should be reflected to the already existed rows in database and only new rows should be inserted.I am using a SQLDataAdapter having two sqlcommands , one for update with update procedure name and parameter mapping and another for insert with parameter mapping.But SqlDataAdapter is inserting fresh new rows all the time in the database table not updating the older one.Please help me in the matterThanks & RegardsVishal Sharma
View 2 Replies View RelatedHi,
I got a problem regarding autoincremental Database Fields and DataTables. Using the technique to map the DataBase to an *.xsd file and trying to insert a Row into the table always results in this kind of error:Cannot insert explicit value for identity column in table 'Cars' when IDENTITY_INSERT is set to OFF.
This only happens when I set CarIDs properties AutoIncrement = true, AutoIncrementSeed = -1, AutoIncrementStep = -1. Having AutoIncrement = false, results in this error:Column 'CarID' does not allow nulls.
Do I missunderstand something, or do I need to change some parts? I would be glad if someone could help me and figure out what I am doing wrong.Thanks a lot have a nice weekend.Regards Johannes
Hi everybody,
I am using VB Webforms as my front end and MSDE 2000 as my back end. I am not able to drop a database after executing the following vb code on that database:
Dim vConnection As New SqlConnection(vConnectionString) Dim vAdapter As New SqlDataAdapter("SELECT party_type_code, party_type_name, party_type_imported" & _ " FROM Party_Type" & _ " ORDER BY party_type_name", vConnection) Dim vDataTable As New DataTable() vAdapter.Fill(vDataTable) vAdapter.Dispose() vConnection.Dispose()
On trying to drop the database using the SQL Command "DROP DATABASE PPCABCD2005", I get the error message:Cannot drop the database 'PPCABCD2005' because it is currently in use ...However, if I don't execute the above code, I am able to drop it. Why is it so? What is the solution to this problem?

View 4 Replies View RelatedI'm working with a legacy database whose structure I cannot change. I'm building a web-based editor for one of the DB's tables. This table has a Primary Key called "Master_Idx" that is an Identity (autonumber) field.To start, I query the DB and populate a data table which is cached. This is used to "feed" the web form. Any additions, changes, and deletions are reflected in this cached table.The user then has the flexibility to press Save at any time, which ensures that the database is modified accordingly.Here's my question:When new records are added, I assign them a Master_Idx value, the first of which was calculated to be 1 + the Max(Master_Idx) value when the editing session started. But when I insert these records back into the database it's possible that another user might have also been doing similar editing (of different records from the same table), so there's no guarantee that the Master_Idx values in the data table will be identical to those in the DB. When I insert a record from the cached table back into the DB, what technique can I use to check what value was assigned to the Master_Idx? If it's not the same as in the cached table then I need to update it locally in a few places.I hope all of this makes sense but if it doesn't then let me know and I'll explain it in another way.Robert W.

I have a *.sql script that creates database tables, and I need to modify the database to enable the service broker. In addition, the actual name of the database is not known in advance - it is set per instance of the application.
I know I need to do:
ALTER DATABASE dbname SET ENABLE_BROKER
But I must avoid including the name of the database in the script. I did wonder if this would work:
DECLARE @DB varchar(50)
SELECT @DB = DB_NAME()
ALTER DATABASE @DB SET ENABLE_BROKER
But I just get a syntax error. Presumably this also rules out setting the database name as a parameter to the script (SqlParameter stuff)
The only option I can think of is dynamically creating the statement, either in T-SQL or in the calling .NET environment.
Any thoughts?

I've read that when this run's, it removes all db mirroring information on that db. What exactly does it remove?
Here's my senario:
We are using SQL 2005€™s db mirroring process. We are using the certificate method of authentication between the principle and the mirror db€™s.
My question is that when the ALTER DATABASE dbname SET PARTNER OFF is run, does it remove these certificate settings as well? In other words when I want to enable the db mirroring, will I need to recreate these certificates or just recreate the endpoints to use these certificates?
I made a website in ASP.net and using sql server 2005 as database. There is sometime processing data that need long time processing ( about 20 minutes ) and big data. It works fine in dev box, but when I place on shared hosting, and some people access it crashed. The website can not be accessed. Hosting support told me maybe I need to reprogram my code. So anybody has solution for this problem ? Should I create new thread ?
View 3 Replies View RelatedHey I was wondering if you
all could help me with my database. I am very noobish as databasing and I am
not sure what I have is good or bad. This is very long since I tell you basically
what my whole site does/will do. This is in hopes that it will give you a
better understanding of how many database will work.
Japanese WebSite
Purpose of the site:
This sites intention is to help people learn the 2 basic
Japanese character sets Hiragana and Katakana.
Hiragana is usually used for Japanese words and contains 46 basic characters,
plus a set of special characters. Katakana is usually used for foreign words
and also contains 46 basic characters plus a special set of characters.
Hiragana and Katakana are written differently when they are written with Japanese
characters. However if you right them in romaji (this is basically writing words
as if you where writing English and does not involve using characters. This is
used for foreigners while they are learning how to write the Japanese
characters).
Hiragana and Katakana are pronounced exactly the same.
This site will use a quiz style format. The user will first choose from the set
of Hiragana characters then the Katakana characters. Once chosen the website
will randomly choose a character and display the Japanese symbol of it. The user will then write the romaji
representation in the text box provided.
It will be then checked
and if the user is right they will get a new symbol. If they are wrong they
will have try again. The purpose for
this is for the user to get use to see how the character looks like but at the
same time writing in romaji what will be easier for them. This should make it
easier for them the next time they see the character to know how to say it.
Version 1
The site will go through many versions. This version I am
focusing on using C#,asp and ms sql. Later on in future versions ajax and
javascrip will be introduced and parts will be changed. Version 1 also uses CSS
and html.
Version 1 will contain these features.
1. A
practice section. A user will go through a wizard like setup that will first
let them choose from the basic 46 Hiragana characters (the other special
characters will be added later). They will then go to the next setup and choose
from the 46 basic Katanana characters. After they go to another section that
asks them how many repetitions they want to go through. If the user is a member(free membership) they
will have the option to save their settings that will be stored and later
available on the front page called quick links. The next page of the wizard is
actually going through the quiz. Once they are done they will see a summary of
how many they got right,wrong and how many they needed assistance on. At this
point they will be able to view a chart to see their progress(current chart
showing there last attempt, a week one
and a month one). These charts will be either made using c# or ms sql(I saw a
something that says you can make something like that but have not confirmed
it). I may do both ways for a learning experience.
2. A Registration form, login and logout.
3. Quick
link. Quick link will be for registered members so they don’t have to go
through the wizard every time to make their practice quiz up. A user will go
through the wizard once and choose what they want and save it. Quick link will be on all the pages in the
form of mostly likely a grid view. A user will be able to store 3-5 different quiz’s
(in the future maybe more). A user can then click on the quick link and it will
just take them to the quiz. The user will also will be able to update their
quiz through the grid view. This will take them to the start of the wizard and
they can go through it again and then just save over it. They will also be able
to delete there quick links through the grid view.
Currently done
Half of step 1 has been completed. Currently a user can
go through the wizard and select what they want and choose how many repetitions
and go through the quiz. However the summary and charts are not done.
Future versions.
Design will be a major part of it since I have not
focused on this at all. Also since I wanted to experiment with dynamic controls
I made all the checkboxes for the selections dynamically. This caused a problem
that a user must hit a save button since the controls have to get recreated and
updated.
I think normally this might not have been a problem but
since I since I am using a multiview(to create a effect that the wizard is all
on the same page and not the whole page has to be reloaded) it caused some
problems(I can’t really remember since it was a couple months ago when I
started but had to stop due to the amount of school work). This is why I want
to go back later and make them with ajax. This also makes another learning
experience.
Where I am at now.
When I started this I really did not think much of my
database mainly because I am not good at data basing and don’t really like it that
much. I have had a course in data basing (was with oracle though)that was part
of my program. At the time I did not understand very much since I found the
teacher going too fast and he started at chapter 8….. Also when you got 7 other
courses with it it’s hard to learn lots.
I have gone through some tutorials and stuff. I am not
very keen on reading a database book since I just don’t have the time since I
want to also read a book on c#, javascript, ajax and so forth. Also I don’t
know how much I will retain/learn from a book. With some of the stuff I just
find its better to try to something where you will be interested in and then
when needed read chapters of a book or ask questions. This is what I done for my c# stuff like I
had a c# with asp course and 2 months after the courses I started this site and
I had to ask myself what the heck did I learn in that course since it seemed I
knew nothing(and I was close to top in my class). With pounding it out and
reading I was able to accomplish what I needed. Like I still want to read a
book on C# but for now it’s just not going to happen same with Data basing.
All the pervious information was so you can understand
what my website is trying to do so you can better evaluate my database design
and answer my questions.
First Design of my
database.
This is when I just made it up on the spot and did not do
any database design or anything.
Question 1: I
forgot how to limit select query results. Like If I just want to show 10 query
results how do I do this?
I have currently 2 tables How one called Hiragana and the
other Called Katakana
HiraganaID = PK
HiraganaID HiraganaCharacter HiraganaImage
----------- -----------------
--------------------------------------------------
1 a Images/hiragana/a-o/a.jpg
2 i Images/hiragana/a-o/i.jpg
3 u Images/hiragana/a-o/u.jpg
4 e Images/hiragana/a-o/e.jpg
5 o Images/hiragana/a-o/o.jpg
6 ka Images/hiragana/ka-ko/ka.jpg
Katakana
KataKanaID = PK
KatakanaID KatakanaCharacter KatakanaImage
-----------
-------------------------------------------------- --------------------------------------------------
1 chk_Kata_a
Images/katakana/a-o/a.jpg
2 chk_Kata_i
Images/katakana/a-o/i.jpg
3 chk_Kata_u Images/katakana/a-o/u.jpg
4 chk_Kata_e
Images/katakana/a-o/e.jpg
5
chk_Kata_o
Images/katakana/a-o/o.jpg
I quickly found that this design was very bad since I was
unable to add new rows very easily. Each character set has each of its characters
in rows of 5. Some rows however have only 3 romaji characters so what they do
is leave the other cells blank representing that they don’t exist. I wanted to
do this too so I figured the easier way would be to have just null rows of
data. So say for “ya,yu,yo� it would be like this “ya,null,yu,null,o�. That’s
how it would appear in the database so when my c# would read it in it would not
have to account for rows that had less than 5 characters since it would have
already the nulls for it.
You can check a chart out here: http://www.alpha.ac.jp/japanese/img/moji.gif
So with this poor design it would result me in basically
rewriting the database.
I have thought of 2 possible ways to. I am not sure if
either way is good but I will try to explain my reasoning as much as I can.
Possible Way 1
In this approach I have 5 tables.
Hiragana
This table stores all the information about Hiragana
Characters
CREATE TABLE [dbo].[Hiragana](
[HiraganaID] [int] IDENTITY(1,1) NOT NULL,
[HiraganaCharacter] [varchar](5) COLLATE
SQL_Latin1_General_CP1_CI_AS NULL,
[HiraganaImage] [varchar](50) COLLATE
SQL_Latin1_General_CP1_CI_AS NULL,
[SortOrder] [numeric](3, 0) NOT NULL,
CONSTRAINT [PK_Hiragana] PRIMARY
KEY CLUSTERED
Katakana
This table stores all the information about Katakana
Characters
CREATE TABLE [dbo].[Katakana](
[KatakanaID] [int] IDENTITY(1,1) NOT NULL,
[KatakanaCharacter] [varchar](50) COLLATE
SQL_Latin1_General_CP1_CI_AS NULL,
[KatakanaImage] [varchar](50) COLLATE
SQL_Latin1_General_CP1_CI_AS NULL,
[SortOrder] [numeric](3, 0) NOT NULL,
CONSTRAINT [PK_Katakana] PRIMARY
KEY CLUSTERED
Quick Links
This table will store the users quick link information.
CREATE TABLE [dbo].[QuickLinks](
[QuickLinkName] [varchar](50) COLLATE
SQL_Latin1_General_CP1_CI_AS NOT NULL,
[UserID] [int] NOT NULL,
[SavedCharacters] [varchar](200) COLLATE
SQL_Latin1_General_CP1_CI_AS NOT NULL,
[SavedImagePaths] [varchar](200) COLLATE
SQL_Latin1_General_CP1_CI_AS NOT NULL
) ON [PRIMARY]
Users
This will store login information.
CREATE TABLE [dbo].[Users](
[UserID] [int] IDENTITY(1,1) NOT NULL,
[UserName] [varchar](30) COLLATE
SQL_Latin1_General_CP1_CI_AS NOT NULL,
[EmailAddress] [varchar](50) COLLATE
SQL_Latin1_General_CP1_CI_AS NOT NULL,
[Password] [varchar](50) COLLATE
SQL_Latin1_General_CP1_CI_AS NOT NULL,
[DateTimeStamp] [smalldatetime] NOT
NULL,
CONSTRAINT [PK_Users] PRIMARY
KEY CLUSTERED
Charts
This will store all information that will be used for
charts.
CREATE TABLE [dbo].[Charts](
[PracticeNum] [int] IDENTITY(1,1) NOT NULL,
[UserID] [int] NOT NULL,
[Correct] [numeric](3, 0) NOT NULL,
[Wrong] [numeric](3, 0) NOT NULL,
[AssitanceNeeded] [numeric](3, 0) NOT NULL,
[TimeDateStamp] [smalldatetime] NOT
NULL,
CONSTRAINT
[PK_Charts] PRIMARY KEY
CLUSTERED
(
Relationships
Users and QucikLinks have a PK to FK relationship this is
because quicklinks is dependent on the user having a user account. It also away
to identify which QuickLinks will belong to who.
Question 2: Currently I don’t have a primary Key for this
table what would be a good primary key for this table?
QuickLinks also does not have any relationship to either
to HiraganaCharacters or Katakana Characters. This is because I did not feel it
was necessary to grab the information from here. I simply could just grab it
from the array that holds this information from my c# code.
Question 3: How can I make this table for all users? Like
Say they choose 5 characters and save it as QuickLink1(as the
QuickLinkName). Should each of these 5
characters gets its own line or should it all be saved in one row? Or should I
even have another table to hold this data?
Option 1
QuickLinkName UserID
SavedCharacters SavedImagePaths
---------------- ----------- ------------------- --------------------------
QuickLink1 1 a image/a.jpg
QuickLink1 1 i image/i.jpg
QuickLink1 1 u image/u.jpg
QuickLink1 1 e image/e.jpg
QuickLink1 1 o image/o.jpg
QuickLink1 2 a image/a.jpg
QuickLink1 2 ya image/ya.jpg
QuickLink1 2 ki image/ki.jpg
QuickLink1 2 yo image/yo.jpg
QuickLink1 2 n image/n.jpg
Option 2
QuickLinkName UserID
SavedCharacters SavedImagePaths
---------------- ----------- ------------------- --------------------------
QuickLink1 1 a,i,u,e,o image/a.jpg, image/i.jpg,
image/u.jpg, image/e.jpg,
image/o.jpg,
QuickLink2 2 a,ya,ki,yo,n image/a.jpg,
image/ya.jpg,
image/ki.jpg, image/yo.jpg,
image/n.jpg,
Charts table also has a Relationship with Users
The thinking for this one is that Charts will use the
UserID to tell who this data belongs too. It will store the number of correct
answers, wrong answers and AssitanceNeed. This table will also hold a timeDateStamp.
The reason for this is because I want to have a chart that displays the last
Quiz they did and also the stats of a week’s worth of quizzes, and month’s
worth of quiz’s. With a timeDateStamp I should be able to add up all those columns
and then display them for whatever period I choose.
Second Possible
Way.
Characters
CREATE TABLE [dbo].[Chracters](
[CharacterID] [int] NOT NULL,
[CharacterName] [varchar](5) COLLATE
SQL_Latin1_General_CP1_CI_AS NULL,
[CharacterPath] [varchar](50) COLLATE
SQL_Latin1_General_CP1_CI_AS NULL,
[SortOrder] [numeric](3, 0) NOT NULL,
CONSTRAINT [PK_Chracters] PRIMARY
KEY CLUSTERED
This way uses 4 charts instead of 5. The main difference
is that the Hiragana Charts and Katakana Charts have been merged into one
table.
This way has another relationship between Characters and
Quick Links. This will store the Character
ID instead of the actual Characters and Path through the use of C# code. When a
user selects a box it will make a note of the CharacterID. When it is time for
the user to use the QuickLink it will join the tables together and filter out
the CharacterIDs. Giving me the CharacterName and Path.
The problem with this way is that well the code I written
will need to be changed since currently it grabs stuff from 2 tables into one.
I don’t know if this would save anytime over the first way either.
I hope these are sort of close to an alright design since
I did try to think about how my website would interact with the database.
Sorry for it being so long.
Summary of Questions
Question 1: I
forgot how to limit select query results. Like If I just want to show 10 query
results how do I do this?
Question 2: Currently I don’t have a primary Key for this
table what would be a good primary key for this table?
Question 3: How can I make this table for all users? Like
Say they choose 5 characters and save it as QuickLink1(as the
QuickLinkName). Should each of these 5
characters gets its own line or should it all be saved in one row? Or should I
even have another table to hold this data?
i'm using DTS to copy one database into a new database, copying over everything, i.e. stored procedures, views, etc.. not just the tables.. how long should it take? it's been stuck at 22% now for about 15 minutes?
thanks
I had a database of electronic resources which had 28000 records earlies and was working fine. Now we have added a whole bunch to make it 800K records which has increased the search time to 14-22 seconds which is not acceptable. I have all the tables indexed.
Please help me how to solve this problem. Let me know what other information I should put up here to make my problem undestandable.
Thanks in advance,

My company is considering purchasing MS SQL Server to run anapplication on (SASIxp). I am mainly familiar with Oracle, so I waswondering how long it would take to copy a database. Basically we havedatabase A and each night we want to replace database B with thecontents of A. How long would this take say if we had a 10GB databaseor a 20GB database.What would be the technique to do this nightly, the Copy DatabaseWizard, Snapshot Replication, Attach & Detach...? We need to automatethis process, and the source database can be made unavailable whenthis happens.Thanks,Roger

I got the error message when I try !
Conrad writes "I'm currently working on Table Partitioning. I have done everything succesfull for partitioning, what I'm struggling with is to use
" SELECT MAX(NAME) from sys.filegroups WHERE NAME NOT LIKE 'PRIMARY' " to get the last used FileGroup. Now this works just fine, but when I run the following script:
--Decalre variables
DECLARE @LastFilegroupName VARCHAR(50)
DECLARE @FilegroupName VARCHAR(50)
--Retuns the next FileGroup to be used
SET @LastFilegroupName = (select MAX(NAME) from sys.filegroups WHERE NAME NOT LIKE 'PRIMARY')
SET @LastFilegroupName = Replace(@LastFilegroupName,'FileGrp','')
SET @FilegroupName = 'FileGrp' + CAST((@LastFilegroupName + 1) as varchar(10))
--Alter database statement
ALTER DATABASE VadivelTesting
ADD FILEGROUP @NewFG_Name
This script gives the following error "Incorrect syntax near '@NewFG_Name'."
When I give it a static name it works fine, but not with the variable.
Please can someone help me, I'm in struggeling with this one."
