Reservation System
Aug 27, 2007
I am trying to come up with a query for a reservation system for a small hotel. I have come up with 5 tables, of which only two will be used when searching for a vacant room. The first table is a roomTable and this contains info regarding the rooms at the hotel. eg room# floor, serviceStatus. The primary key in this table is room#.
The second table involved is a Session table. This table has a session number as primary key, and also has room# as foreign key. This table also contains a sessionType, startDate of a session and an endDate. Every time a room booking is made or a user is checked into the hotel a session is recorded into the sessions table.
When searching for room, the user supplies the date when the session should start and the date when this session should then end. I need a query that will enable me to pick all those rooms that are in the roomTable but do not have sessions running during / between the startDate and endDate specified by the user.
If anybody could be of assistance I would be most greatful

Hi, I'm having issues trying to get a query working the way I want, it maybe
that i'm overly complicating things though.
What I have done so far is have 2 seperate tables one holding details about
the item to be booked out with an ID the second linking to the Item via the
ID and also having the startdate and the enddate of the booking, thus an item
will have multiple rows in the bookings table for multiple bookings.
What I want to have is a "quick" booking method where a user enters the
startdate they would like and the enddate, a drop down is then filtered (via
a query) returning only the items that are avalible.
The issue i'm having is that because my bookings have multiple rows for each
item, for what maybe true in the rules for an item in 1 row maybe false
alittle later - i which case the returned data i am getting is incorrect!
Hopefully I have made sense, and maybe someone can help?
my querry for the filter so far: -
SELECT DISTINCT DeviceDetails.Device_ID, DeviceDetails.Device_Name
FROM DeviceDetails LEFT OUTER JOIN
BookingDetails ON BookingDetails.Device_ID =
DeviceDetails.Device_ID
WHERE (BookingDetails.Bookout_Date IS NULL) OR
(BookingDetails.Bookout_Date >= GETDATE()) AND
(@Dateout <= BookingDetails.Bookin_Date) AND (BookingDetails.Bookout_Date >=
@Datein) OR
(BookingDetails.Bookout_Date >= GETDATE()) AND
(@Dateout >= BookingDetails.Bookin_Date) AND (BookingDetails.Bookout_Date <=
@Datein)

I am building a small app that will display availability data for properties. I have a calendar that displays the dates for a whole year in month rows with each days colour representing the availability status, i.e. booked, on hold etc.
My question is about how to store these dates in the db. At the moment I have the table below:
TABLE Availability [PropertyID] [int] NOT NULL , [StatusID] [tinyint] NOT NULL , [StartDate] [smalldatetime] NOT NULL , [EndDate] [smalldatetime] NOT NULL
I was planning on having four status's for any given date, unknown, available, on hold or booked.
Displaying the dates has proved pretty simple but updating availability means I would need to query the db to see if any of the dates overlapped, I would then have to add the new date range/status as well as change any date ranges that overlapped, either in the sp or in the code and this is what made me wonder if there was a better way.
Does this sound a reasonable approach? Any advice or pointers would be greatly appreciated, This is the first time I have had to store date ranges and I want to make sure I am doing it right.

I have a project need to store the information of reservation. For example, somebody wants to reserve a laptop. She will sign in the date from calender to use. I would like to let the administrator to access the database and update the database in the intranet. Also the user who want to reserve a resource can access the intranet to fill a form, after approving it, she can borrow the resource. Of course, this is small database. And we also have a report on this.Do you have any idea how to do it? I appreciate.

We are running with a 2 node windows cluster having three SQL instances on it.Â
OS: Windows server 2008R2 SP1
SQL : SQL server 2008R2 (10.50.6529)
Currently both nodes have 256 GB or memory and we are having multiple auto failover for resources. What will be the best practice for OS memory reservation (OS+tools) so that we can set SQL max memory settings accordingly?

Hello, all
We are trying to work out a memory problem associated with a SQLCLR procedure we have developed.
This procedure will run properly on a SQLExpress box, but fails with an Insufficient Memory error (701) when run on our 32-bit enterprise edition server on W2K3 Enterprise Server. The server has 3.25 GB of RAM, and does *not* have the /3GB switch enabled; AWE is *not* enabled on SQL Server.
I initially suspected the problem was due to the idiosyncracies of how the BPool is allocated on SqlExpress and its 1GB buffer pool limitation, giving a 1GB MemToLeave region for SQLCLR allocations -- substantially larger than the default available on the server with it's default 256MB allocation (+128MB for thread stacks). That seemed to explain why a memory problem might not manifest itself on the client, but would on the server. I then altered the server to include an explicit "-g" parameter at startup, reserving 512MB for MemToLeave, but the query still fails with the same memory errors. I've tried values as high as 1GB (-g1024), but none have worked Our DBA has installed a recent hotfix associated with certain memory errors, to no avail.
It appears that the server will max out the CLR allocations at 102MB, regardless of the presence of the -g parameter. Could it be that the MemToLeave region really is that severely fragmented? There are still log messages indicating failures to reserve virtual memory...
One thing I notice is that the buffer's VM Reserved value never seems to change regardless of the value of the "-g" option. I would expect to see it decrease by the amount specified as reserved, eg -g 768 should leave, for example, something like 1.2GB VM Reserved for buffer pool allocation, but it doesn't. That tells me I'm not really establishing a larger MemToLeave area. Is this expectation incorrect?
Bottom line, we don't know why this procedure is running on the server, but not in SqlExpress. It is a procedure that connects to a remote Oracle database and collects about 14,000 records, but dies after sending about 7,000 or so records when run on the server. Again, the same query running against the same code on a SqlExpress box works perfectly.
Any thoughts or suggestions welcomed and greatly appreciated.

I have created a windows library control that accesses a local sql database
I tried the following strings for connecting
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"
I am not running the webpage in a virtual directory but in
C:Inetpubwwwrootusercontrol
and I have a simple index.html that tries to read from an sql db but throws
the error
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,
etc etc
The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted
I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security
I think that a windows form connecting to a sql database running in a webpage should be simple
to configure what am I missing?

Ok guys, I am trying to install Sql server 2005 on Vista but I am still stuck with this warning message in the System Configuration Check during Sql server 2K5 installation :
SQL Server Edition Operating System Compatibility (Warning)
Messages
* SQL Server Edition Operating System Compatibility
* Some components of this edition of SQL Server are not supported on this operating system. For details, see 'Hardware and Software Requirements for Installing SQL Server 2005' in Microsoft SQL Server Books Online.
Now, I know I need to install SP2 but how the hell I am going to install SP2 if Sql server 2005 doesn't install any of the components including Sql server Database services, Analysus services, Reporting integration services( only the workstation component is available for installation)?
Any work around for this issue?
P.S.: I didn't install VS.NET 2005 yet, can this solve the problem?
Thanks.

Hi,I have a few things on my databases which seem to be neither true systemobjects or user objects - notably a table called 'dtproperties' (createdby Enterprise manager as I understand, relating to relationship graphingor something) and some stored procs begining with "dt_" (some kind ofsource control stuff, possible visual studio related). These show up whenI use"exec sp_help 'databaseName'"but not in Ent. Mgr. or in Query Analyzer's object browser, and also notin a third party tool I use called AdeptSQL. I am wondering how thosetools know to differentiate between these types of quasi-system objects,and my real user data. (This is for the purpose of a customized schemagenerator I am writing). I'd prefer to determine this info with systemstored procs (ie sp_help, sp_helptex, sp_...etc) but will dip into thesystem tables if needed.Thanks,Dave

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

MS documentation is short when it comes to explanation of Quiescing a system for peer to peer replication. It seems that for any change the whole p2p machine has to stop ? This would cripple our development/releases... Is it really the case ?
Can all p2p nodes be quiesced except one, the one when I would also make changes ?
i.e. N1 <> N2 <> N3 I would stop inserts/updates/deletes for N1 & N3 and keep inserting/updating/deleting for N2 as I'm making schema change on N2 (additional table, additional field etc). Would it work ?
Also, would I need to stop selects for N1 & N2 ?
Thank you.

Greetings everyone, I am attempting to build my first application using Microsofts Sql databases. It is a Windows Mobile application so I am using Sql Server Compact 3.5 with Visual Studio 2008 Beta 2. When I try and insert a new row into one of my tables, the app throws the error message shown in the title of this topic.
'((System.Exception)($exception)).Message' threw an exception of type 'System.NotSupportedException'
My table has 4 columns (i have since changed my FavoriteAccount datatype from bit to Integer)
http://i85.photobucket.com/albums/k71/Scionwest/table.jpg
Account type will either be "Checking" or "Savings" when a new row is added, the user will select what they want from a combo box.
Next is a snap shot of my startup form.
http://i85.photobucket.com/albums/k71/Scionwest/form.jpg
Where it says "Favorite Account: None" in the top panel, I am using a link label. When a user clicks "None" it will go to a account creation wizard, and set the first account as it's primary/favorite. As more accounts are added the user can select which will be his/her primary/favorite. For now I am just creating a sample account when the label is clicked in an attempt to get something working. Below is the code used.
private void lnkFavoriteAccount_Click(object sender, EventArgs e)
{
FinancesDataSet.BankAccountRow account = this.financesDataSet.BankAccount.NewBankAccountRow();
account.Name = "MyBank Checking Account";
account.AccountType = "Checking";
account.Balance = Convert.ToDecimal("15.03");
account.FavoriteAccount = 1;//datatype is an integer, I have changed it since I took the screenshot.
financesDataSet.BankAccount.Rows.Add(account);
//The next three lines where added while I was trying to get this to work.
//I don't know if I really need them or not, I receive the error regardless if these are here or not.
this.bankAccountTableAdapter1.Update(financesDataSet);
this.financesDataSet.AcceptChanges();
refreshDatabase();
}
the refreshDatabase() code is here:
private void refreshDatabase()
{
this.bankAccountTableAdapter1.Fill(this.financesDataSet.BankAccount);
//Aquire a count of accounts the user has
int numAccounts = financesDataSet.BankAccount.Count;
//Loop through each account and see which one is the primary.
for (int num = 0; num != numAccounts; num++)
{
//Works ok in frmMain_Load, but when my lnkFavoriteAccount_click calls this, it throws the error.
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
{
//Display the primary account on our home page. User can click the link label & be taken to their account register.
this.lnkFavoriteAccount.Text = this.financesDataSet.BankAccount[num].Name.ToString();
this.lnkFavoriteFunds.Text = this.financesDataSet.BankAccount[num].Balance.ToString();
break;
}
}
}
and my form_load code
private void frmMain_Load(object sender, EventArgs e)
{
refreshDatabase();
}
So, when I click on the lnkFavoriteAccount label, and my new row gets added, the app stops at the following line in my DataSet.Designer
[global:ystem.Diagnostics.DebuggerNonUserCodeAttribute()]
public byte FavoriteAccount {
get {
try {
return ((byte)(this[this.tableBankAccount.FavoriteAccountColumn]));
}
catch (global:ystem.InvalidCastException e) {
//Stops at the following line, this error was caused by 'if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)'
throw new global:ystem.Data.StrongTypingException("The value for column 'FavoriteAccount' in table 'BankAccount' is DBNull.", e);
}
}
set {
this[this.tableBankAccount.FavoriteAccountColumn] = value;
}
}
I have no idea what I am doing wrong, all of the code I used I retreived from Microsofts help documentation included with VS2008. I have tried used my TableAdapter.Insert() method and it still failed when it got to
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
in my refreshDatabase() method it still failed.
When I look, the data has been added into the database, it's just when I try to retreive it now, it bails on me. Am I retreiving the information wrong?
Thanks for any help you guys can offer.

Name:Variable datatype int32 values 0
Name: NumberofRowsdatatype int32 values 10000
Name: ObjVariable datatype Object
My code
public override void CreateNewOutputRows()

Add rows by calling the AddRow method on the member variable named "<Output Name>Buffer".
For example, call MyOutputBuffer.AddRow() if your output was named "MyOutput".
*/
System.Data.OleDb.OleDbDataAdapter oLead = new System.Data.OleDb.OleDbDataAdapter();
//System.Data.Odbc.OdbcDataAdapter oLead = new System.Data.Odbc.OdbcDataAdapter();
//SqlDataAdapter oLead = new SqlDataAdapter();
System.Data.DataTable dt = new System.Data.DataTable();
DataSet ds = (DataSet)this.Variables.ObjVariable; // here i am getting error
ds.Tables.Add(dt);
ADODB.Record rs = new ADODB.Record();
oLead.Fill(ds, rs, "Variables");
foreach (DataRow row in dt.Rows)

Output0Buffer.Column1 = row["Column1"].ToString();
Output0Buffer.Column2 = row["Column2"].ToString();
}
}
}
}
This is the error

Hello,
Does anybody could help me to fixe this query, inside SQL Task to handle OnError event.
The function DT_TEXT does not work with this query and I need to convert the Error Message so that the french caracter ' can be accepted inside the Insert Query.
Here is my query :
"INSERT INTO LOG(EventType, PackageName, TaskName, EventCode, EventDescription, PackageDuration, ContainerDuration,InsertCount, Host) VALUES ('OnError', ' " + @[System::PackageName] + "', '"+ @[System::SourceName] + "', 0, '"+ (DT_TEXT)@[System::ErrorDescription] + "', 0, 0, 0, 'Toto'
)"
The error message is capted inside the Insert Query, for example,
the value of the variable ErrorDescription is : 'Erreur dans l'insertion ' with a quote inside, and therfore the Insert Query can not be executed.
Thank you for helping me to fixe this query !

Currently, I have a WinCE application which uses the System.Data from NetCF and System.Data.SqlserverCE from MSSQL Server 2005 Mobile Edition. Now, I'm trying to use the System.Data.Sqlclient but I can't seem to find it in my System.Data. I notice that there are different version which is one from NetCF and one from the MS.Net framework itself.
Here's my question: Is it possible for me to use both System.Data? or should I only choose one. This is for my attempt to connect also from an SQLServer and connect to the local SQLServerCE as well.
Thanks in advance,
