Concert Calendar/reviews Database Development?
May 2, 2008
Hi,
I'm neck-deep in trying to normalize all the info I need into separate tables, but I seem to have hit a wall running.
I was curious as to what the "best" way is to develop a database of concert events would be? What I think I've figured so far would be if I created a table called events...that would be 1 row of data per concert event. Each row could then have a 'event_id' as PK, 'date', and a column with the associated 'band_id' from the bands table. Then anytime the date was accessed (assuming a populated row for that date), a list of concerts for that date would show.
I would also like to use the 'event_id' as an access point for my reviews table...where, quite obviously, I would like to be able to have reviews associated with each event from the calendar as well. Does all this seem right? Or is there a better way (i.e. more efficient, smaller database, and/or use less memory)? How, for example (in short, obviously), does a website like Pollstar.com database their events?
I guess my question with regards to this database is also...within my bands table, should I include their tour dates? Or should I put the band_id in my events table?
I was hoping to get a just a little bit of direction so I don't turn some baby missteps into a long-term project down the wrong road. Any help or response is greatly appreciated. Thanks again!

Our IT is pushing HP Data Protector (HPDP) on us. Anyone ever see it in action?
they are telling us NOT to use the standard MS SQL Backup/restore process, because their HPDP does it for us.
But I have hesitations.
Anyone?

HelloMy department has a SQL server database that is used to all facets ofproduction within our department. This includes key production jobsteps, project names, numbers and descriptions.The calendar is currently done manually as an Excel document. The userrecieves hard copies of the required information, then keys it into theappropriate place on the Excel document.We would like to pull information out of that database, and put it in amonthly calendar format. For example, take a project name and the dateassociated with that project, and put it on a calendar in theappropriate date "square".If you have information or experience with software that can be used toaccomplish this task, I would appreciate hearing your advice.Thanks in advance.

Hi,I m trying to implement a calendar, where you can select certain dates and view list of events for that day. The list is generated from database. I found a script on the web that is quite similar to what i want to achieve. I tried to run this script, however I get an exeption saying:An error has occurred while establishing a connection to the server. .... error: 40 - Could not open a connection to SQL Server)This is the code:SqlConnection mycn; SqlDataAdapter myda; DataSet ds = new DataSet(); DataSet dsSelDate; String strConn; private void Page_Load(object sender, System.EventArgs e) { // Put user code to initialize the page here strConn = "Data Source=localhost;Initial Catalog=pubs"; mycn = new SqlConnection(strConn); myda = new SqlDataAdapter("Select * FROM EventsTable", mycn); myda.Fill(ds, "Table"); //This where I get the exeption } protected void CalendarDRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e) { // If the month is CurrentMonth if (!e.Day.IsOtherMonth) { foreach (DataRow dr in ds.Tables[0].Rows) { if ((dr["EventDate"].ToString() != DBNull.Value.ToString())) { DateTime dtEvent = (DateTime)dr["EventDate"]; if (dtEvent.Equals(e.Day.Date)) { e.Cell.BackColor = System.Drawing.Color.PaleVioletRed; } } } } //If the month is not CurrentMonth then hide the Dates else { e.Cell.Text = ""; } } private void Calendar1_SelectionChanged(object sender, System.EventArgs e) { myda = new SqlDataAdapter("Select * from EventsTable where EventDate='" + Calendar1.SelectedDate.ToString() + "'", mycn); dsSelDate = new DataSet(); myda.Fill(dsSelDate, "AllTables"); if (dsSelDate.Tables[0].Rows.Count == 0) { DataGrid1.Visible = false; } else { DataGrid1.Visible = true; DataGrid1.DataSource = dsSelDate; DataGrid1.DataBind(); } }
Can some one tell me what is wrong with the code.Thank You

Hi,I am trying to create a development database server (make use of an old machine), with which to learn about sql 2005 and oracle etc. I'm using VS 2005 Beta 2 on my development/workstation machine.My workstation and the prospective server are connected via a router and can 'see' each other.I have installed win 2003 server on two seperate partitions (multiple boot) and installed sql server 2005 on one partition and will install oracle 10g on the other. (I understand these two databases can run on the same machine/OS, but I just wanted to keep things tidy and I won't be using them at the same time, so ...).My question is how do I/should I configure win 2003 server / sql server 2005 on my server machine, in order to be able to connect from my workstation via vs 2005 beta 2 ?Any suggestions or resources on configuration appreciated.

I am running both SQL Server 2000 and SQL Server 2005.
Lets say I have a live database that is version 1 for an application. The database is copied onto a development machine to develop version 2 of the application. I want to be able to take a snapshot of the database and then get a program to write all the changes made after the snapshot into sql code. This is so I can run this sql code on the live database and transform version 1 to version 2.
Is there any program/tool that will allow me to do this?

Hi.
I have a question that I have been thinking about for some time. Have in mind that I'm somewhat a SQL newbe.
I work on a few webapplications that are database driven applications. When we desides to change something in the database, we normaly do the changes on our replicat development database, and after some testing the changes are suppose to be implamented in the live, public database.
Now, what is the best way, or recomended way to do this? Today we bo it manualy. But at one time I experimented with the export/import wizard to se if it was possible. What I want to do is change de design of a tabel, without loosing the original data, and without geting the data from the development database into the live database.
To export an stored proccedure, I usualy just create a SQL-script for the procedurs in question and the runthe script against the public DB using the Query Analyser. But if I do the same procedure on a table, I loss all the data in the database.
Do I make any sense at all?
Any tips/idea/best practise on this subject?

Hi,
We're using SQL Server 2000 as back end in our web project. The problem is we've 3 different copies of same database - one each for Development, Test and Production sitting in 2 different machines.
My question is - is there any tool for comparing the objects (tables, stored procedures, etc) ?
Thanks,

Hello,
I am trying to refresh a test database with data from a production database. Both database structures are identical, e.g. constraints, stored procs, PK, etc. I am trying to create a package in SSIS that accomplishes this task and I am having extensive problems. The import export wizard is out of the question because the constaints are not carried over, plus when I try to refresh the data using the import export wizard, it fails on 1 specific table because of a column in that table named "Error code". I think "Error code" is a micrsoft keyword, so it fails on this column. Does anyone know a workaround that I can do to accomplish this simple task, that could be completed in minutes using DTS. I understand that SSIS is not as straight forward as DTS, but this task is something that DBA's do on a regular basis and therefore should not be this difficult.
Any help would be appreciated,
David

Hi,
I work with a large team developing ASP.NET application that has a large database with over 50 complex stored procedures. It is proving more and more difficult and time consuming to centralise the development and update of the database changes and I was wondering if there were any best practises/tools that could be recommended. I have looked on the web for good articles and haven't found anything difinitive (except that Team Foundation Server is the way forward)..
A brief background to the current process is that everyone develops on the same database, and then updates the stored procedure scripts in source safe (manually). Then when we do a new release someone builds a script of all the database updates and runs it. There are issues related to developers updating there stored procedures over other peoples and other concurrency.
I am looking to move all the developers to start using local databases so that there work only effects them, but then this brings up problems of keeping all the local databases up to date whenever they get the latest source code. The only way I currently see is to build a database update program, that will run and update to the latest version.
Surely this must be a common issue? Anyone have any good ideas/concepts?
Also our setup is Visual Studio 2005, SQL Server 2005 and Source Safe 2005.
Cheers,
Andrew Thomas

We are using SQL Server 2012 for both production and development server. Currently, i have plan to transfer the full backup of SQL server database to the development server and then restore it on the development server for testing purpose, so we don't want to disturb on the production.
I have successfully backup the database from the production server and transfer to the development server. however, i encounter some difficulties when trying to do restore. my question is:
1. do i need to firstly create an empty database on the development server and then restore it into this empty database? say i create database call "Test2", then i perform a restore into this database.
2. currently, there is already an existing database being restored previously in the development server and this database is actually the older version of the backup that being restored by the previous engineer. should i remove this database first and restore a new one or both of the database can coexist as long as we put different name for the database?

Hi all! I know I might sound stupid, but I have this problem. I have developed my database on my laptop which does not use Active directory. Lets say I access the database with: SPIDERMANDB1 on SQL server, where the name of my laptop is SPIDERMAN, and the database is DB1. Now, I create an SQL script from sql server and make the necessary changes, like changing the computer name to say, SUPERMAN where my deployment server's name is SUPERMAN. But when I run the SQL script on the SUPERMAN server, it gives me an error like: "User or role SUPERMANDB1 does not exist in this database". I have deployed databases in this way on servers without Acive directory, so I'm sure its not a mistake on my side. So how am I supposed to go around this active directory thingi! Please help me out! I'm counting on u guys!

Hi
Can we use BCP AND/OR BULK INSERT to do development server databse refresh from production server . I have to do this by following the rules below:
- no truncation of source table
- update of changed or new records only.
I know we can use replication, dts and other methods for this but I need information about this one.

Hi,
I'm developing a site in asp.net and one of the main parts is to manage a timesheet.
Now the problem i'm facing is; how do I save this timesheet in a database in a way that it's easy to save and easy to query from.
I'm thinking about problems as i.e. 1st of a month is middle of the week, so I can't save it like this:
Month Week Mon Tue Wed Thu Fri Sat Sun
1 5 .. .. .. .. .. .. ..
2 1 .. .. .. .. .. .. ..
Anyway, I got stuck to find the best method, maybe someone has made something like this?
Thanks in advance!

I have thought about this, and I cannot in my head come up with a way to create this. Maybe I am thinking about it too much, or maybe it is this difficult and I will need a 3rd party tool.
My users have requested a SQL Reporting Services report that looks like a calendar. Each page will be one month on the calendar. And then the data will fall on the calendar according to a date field in the database. It should not be all that difficult, but I cannot think of a way to acheive this.
Has anyone tried to build a report that is basically just a calendar, and each page is a month of the calendar? If so, did you build it using the standard SQL reporting services tools, or did you purchase a 3rd party vendor?
Let me know what route I should look to follow.
Thank you!

Hello there
I'm having a little issue with Updating a SQL Table. *Deep Breath* OK, lets begin from the start...
I Have a Table Called Job. I've an ASP Page setup to insert a new record into the Job table via a DetailsView Control with an SQLDataSource bound to it. This table has many columns in it, 4 of which are DateTime columns. I use a calendar Control from the toolbox for the DateTime selection and bound all the Calender control's SelectedDate to: SelectedDate='<%# Bind('EnteredDate') %>' using the EnteredDate field as my example.
I only insert DateTime Values into 2 of the 4 DateTime columns in the original INSERT, so the remaining 2 columns are NULL. I have an UPDATE setup on a different page to edit the previously inserted rows in job using another SQLDataSource again using the bind method for calendars: '<%# Bind('RevisedDate') %>'
My Problem is (according to this post I found online http://www.thescripts.com/forum/thread529052.html ) the page crashes with "Specified cast is not valid". The reason being I'm trying to bind to the remaining 2 NULL DateTime columns in an attempt to update them with a value my user will not be able to insert in the original INSERT. The solution Code I found on the link above is in VisualBasic and I have had little luck in trying to convert it into C# to even see if it solves my problem:
VB Code:
Function FixDBNull(ByVal inVal As Object) As DateTime If inVal Is DBNull.Value Then Return DateTime.Now Else Return inVal End IfEnd Function
ASP Code:
<asp:calendar id="calEditRevisedDate" runat="server"selecteddaystyle-backcolor="red"selecteddate='<%#FixDBNull(eval("RevisedDate")) %>'visibledate='<%# FixDBNull( eval("RevisedDate")) %>'selectorstyle-backcolor="Green"></asp:calendar>
Any suggestions or work arounds would be greatly appreciated
Thank You

I have 2 dropdownlist and a gridview. The dropdownlists filter the
gridview, but now I have added two calendars and two textboxes. After
user makes selections from the calendar the text boxes are populated
with the dates. How do I add this to the following select parameter so
that the filtering/querying works properly? (what I have here does not
work in terms for the dates, but dropdownlists filter when I remove the
dates section):<asp:SqlDataSource ID="DATA" runat="server" ConnectionString="<%$ ConnectionStrings:DATA_Connection %>"

@Param1='Select something' or((CONVERT(char(10), adate,

adate, 101)>=@param3 AND CONVERT(char(10), bdate, 101)<=@param4))" UpdateCommand="Update atable set afield=@afield, bfield=@bfield where id=@ID" > <selectParameters> <asp:controlparameter name="param1" controlid="DropDownList1" PropertyName="SelectedValue" type="String" /> <asp:controlparameter name="param2" controlid="DropDownList2" PropertyName="SelectedValue" type="String" /> <asp:ControlParameter Name="param3" ControlID="Textbox1" PropertyName="Text" Type="string" /> <asp:ControlParameter Name="param4" ControlID="Textbox2" PropertyName="Text" Type="string" /> </selectParameters>

We have developed several reports using VS 2005 and deployed them to our SQL 2005 reporting server. As most of our reports use date parameters we would like to incorporate a calendar control to allow users to select their date range as opposed to typing them in. I have done some reseach online but can only find vague references on how to do this. Has anyone out there been able to successfully deploy a calendar control onto an SQL report? Thanks!

I'm looking for a function that will return an INTEGER that computes the number of days between two dates based on a 360-calendar year instead of using just the datediff function which is actual days.
If anybody knows where I could find something like this, I would be greatly appreciated.
Does this site have a library of user-defined sql functions? Or, does somebody have a site that you know of where there are a bunch?
Thanks,
