What's Unique For A Song Recording - Band? Artist? Song? Date?
Jan 7, 2008
I'm struggling to design a music database to track artists/bands, albums, songs, recordings etc. I want to identify the fields (including either solo-artist, band or perhaps duet) that make a Recording entity unique. I've considered that Band, Song and Date Recorded would make a unique key for a Recording (though that won't account for multiple recordings on the same day). I believe a Recording should be unique to a Band or a Solo-Artist (but not both, so which?).
I've considered making a Recordings table, a Bands table and a Band_Recordings table (the Beatles may have multiple versions of Yesterday). That would mean Ringo Starr becomes a band! Not quite right. I could call the Band table Acts or Performed_By to include both solo artists and bands but that seems wrong. What would go in the fields First_Name & Last_Name for the Beatles?
I would like to be able to have an Artists table (Ringo, John, etc), a Bands table (Beatles) and a Band_Artists table (Beatles/Ringo, Beatles/John, etc). With this scenario what foreign key lands in Recordings? Artist_ID? Band_ID? Both? And again, what fields combine to uniquely identify a Recording?
Another part of my problem is that for one Recording (Beatles/Yesterday), I'd like to also identify it as a Paul McCartney Recording (or John, George or Ringo) in addition to being a Beatles Recording.
I'm stuck! Certainly this type of database is often created, but I can't see how. Any answers or guidance is much appreciated.
i am looking for free db's for download ... mainly looking for a massive music artist db i can grab ... also a state/province all to use with Mysql and php front end ... anyone know a good resource website?
First, yes I know that DB Library is depreciated. Unfortunately it isn't an option for us to make a huge change like that right now.
Now, on to the problem. We have a few different C applications that access SQL Server via db-lib. On SQL 6.5, and SQL2000 we had no issues to speak of. Since upgrading to SQL2005 (Enterprise Edition, 32 bit), we have had a horrible time with receiving an error that says "Error msg: Possible network error: Error in sending out-of-band data to SQL Server. General network error.". It appears to happen at somewhat random times during the applications run.
Search for information on "Error msg: Possible network error: Error in sending out-of-band data to SQL Server. General network error." has provided next to nothing, so I turn to you. Any ideas?
Hello,How can I record certain type of querys ? I would like to recorddelete command sent to a specific database, and using a specificlogin account.This "query capture" should run in background because I don´t knowthe exact time someone will delete a record.I´m using SQL-Server 7.0Thank you,Eduardo.
I am looking for information on the SQL server 2005 performance, mainly on the data recording speed. I have a project where I have to save approximately 20000 analogical value per second.
Hi, all:I have been tasked with determining how many licenses of a certain SQLServer 2000-based application are actually in use: in other words,record or log connections made to the database by clients.Client connections will be made with a generic SQL Server ID which hasbeen granted access to the DB; security is maintained inside theapplication, and a user only logs in with their personal ID in theapplication itself.I know I can go in at any time into the management/CurrentActivity/Process info and see current sessions against the target db,grab the host name from that view, and do an "nbtstat -a" to glean thelogin ID of the connected user.If there were a way to record connections made to a DB in the eventviewer or SQL log, I could hopefully get the information I need.But I see no way to have the SQL Server log connection information likethis.Does anyone know how I might collect this info?Thanks!Cheers,BD
I'm sorry for asking this, as I'm sure tha the answer is in one of the 208 matches I found searching on "ErrorCode". Unfortunately, this project is overdue and I need a solution fairly soon.
I should add that I've only been developing in SSIS since August 2007.
I have a complicated package, loading about 17 outputs of the XML Source into staging tables. I have been using the error outputs of any standard components I use, out of faith that, if Microsoft provided them, then they should be useful for something. I've been directing all of the error outputs for one of the 17 "tables" from the XML Source into a Union All, and then into an "Error staging table", for each of the 17 outputs. This table includes all of the possible columns, but permits nulls for all of them. It also incldues the ErrorCode and ErrorColumn.
Unfortunately, if these latter two are useful for anyting, I haven't found it yet.
Right now, working with our first "mostly real" data, I'm getting 100% of my input rows written into error tables. Unfortunately, the information in the tables are of limited use in determining what went wrong. For instance, the ErrorColumn seems only to be populated if there was a specific error with a specific column. The Lookup component, doesn't seem to populate ErrorColumn, even if only one column was used for the lookup! No information about the component producing the error output is supplied in the error output, either, which makes it difficult to determine which of the five or so possible error outputs is the one that produced the particular error row.
This proves that I'm missing something simple. How do people handle errors? In my custom components, I learned to use the Fire* methods to produce detailed messages before redirecting the row to the error output, but this sort of thing is not available through the standard components.
Do I really have to create a separate "add useful information to the error output" component, and use it on each error output?
Sorry for the attitude, but just when I think I'm winning, SSIS brings me back down to earth!
I have 2 higher level column groupings of month name and year above my actual date groups. It looks a little weird aligning them left but there is no guarantee that centering them will even allow them to show until I've scrolled right to the middle of the cell width that they occupy.
Is there a feature that comes with, or a well known trick for making them center in the area that is being viewed instead of the potentially very wide cell that they occupy?
We have a field that is defined as a string which is used to store a date. The format of the date can be any interpretation of a date as long as it follows the sequence of day/month/year. Insomuch as,
12/10/2000 is 12th October 2000 as well as 12/10/00
Because the yyyy date can be 2000 or 00 we are having problems with the following syntax:
SELECT Convert(Datetime, myproblemfield, 103) As YetAnotherProblem FROM SomeTable WHERE YetAnotherProblem < #12/10/2000#
Any whiz kids out there who can help.

I am working on a software primarily related to accounting with visual basic
Many of the problems and proposed several solutions for running sum, but I have read almost all of these interpretations,
have applied when running sum is a unique ID field. but almost all of the functioning of accounting reports are in chronological order. So he questioned what was the balance on 05.05.2012.
ID of the process is done, if the user enters a process backward a few things since then, the transaction date is old, but the ID is new, are experiencing problems. eg
ID DATE DEBIT CREDIT BALANCE
1 02.02.2012 100.00 0.00 100.00
6 04.04.2012 0.00 150.00 -50.00
3 02.05.2012 70.00 0.00 20.00
4 02.05.2012 80.00 0.00 100.00
2 06.06.2012 120.00 0.00 220.00
must balance the figure above.
if ID = 2 record, the record date 06/06/2012 and if the ID = 6, date 04/04/2012, the date the order is made if the listing is experiencing trouble getting balance. 2 records in the same day when the balance at worst formula breaks down. The big point is that I hang out in my project.
the only solution is to use a temporary table or writing about it in Visual Basic seems to calculate. the use of temporary table is not a solution, but unfortunately also very fast.
I have a equipment table and the equipment has a coding for each place / location or custody it has had during its life. I need to select the latest (newest) row for each piece of equipment by getting the newest from_date and to_date field combination.The following is an example. I know how to get MAX date for one column but not with two columns (from and to DATES).
I want to select unique country - date pairs. It is not even necessary to have the count of each one, just the list of unique country/dates.
My query here uses 'group by' to accomplish this task, but there may be a way to do this with a self join. I believe using a self join would make the query faster.
I have an Orders table which has the following fields:
OrderID (PK, int, auto increment, not null) CustomerID (FK, int, null) PaymentDate (datetime, null) UserID (uniqueidentifier)
(and other irrelevant fields)
Basically, for a specific PaymentDate range (29th July 2014 - 26th August 2014, inclusive) I want to select all orders where they only appear once in the orders table based on the CustomerID, so I only want to know about them if they have a paid order (decided by PaymentDate not being null) in that date range, but also taking into account if they have ever had a paid order outside of that date range. I'll also be joining on to the aspnet_Users table to get the username assigned to that order.
Select p.Id [SenderId], p.Username, up.PhotoId, CASE WHEN mr.ReadDate is null then 1 -- New message ELSE 0 -- Message has been read END AS NewMessage, p.LastLoggedIn, p.LoggedIn
[Code] ....
The above query returns me all messages (inbox functionality) that have been sent to mr.ReceipientId, the issue I have is when I send another email to the recipient the readdate field will be null, and the other emails linked to the recipient which have also been sent via me will have a readdate date. This causes duplicate rows to appear due to the case statement, I'm trying to figure out if / how it is possible to only display the one row per conversation and set newmessage to 1 if there is an un-read message otherwise show 0 ?

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.
What's the difference in the effect of the followings: CREATE UNIQUE NONCLUSTERED INDEX and ALTER TABLE dbo.titles ADD CONSTRAINT titleind UNIQUE NONCLUSTERED
I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?
Hi everyone, I need urgent help to resolve this issue... As far as the performance goes which one is better.. Unique Index(col1, col2) OR Unique constraint(col1, col2) ? Unique constraint automatically adds a unique index and unique index takes care of uniqueness then whats the use of unique constraint ?
BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?
hi team, .Can i create umique constraint with out unique index.when i am creating a unique constraint sql creates a unique index (default) can i have only unique constraint ?
I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today. Here is the code
Code Snippet create procedure SearchPartKeyword ( @Keyword varchar(250) = null, @Universal_Id varchar(10) = null ) as select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM, p.Legacy, p.Folder, p.Printer from Parts p inner join notes n on p.PartNumber = n.Identifier where n.Universal_ID = @Universal_ID and p.Description like @Keyword union select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly, p.DMM, p.Legacy, p.Folder, p.Printer from Parts p where p.Description like @Keyword
and the results: PartNo Description SO Notes LA DMM Legacy Folder Printer de90008 MAIN BOARD 1 DGF1 114688 0 0 0 de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
create table Test ( [recId] [int] identity(1, 1) not null, [code] [varchar](50) not null, [prime] [bit] not null constraint [DF_Test_prime] default (cast(0 as bit)), constraint [PK_Test] primary key clustered ( [recId] ) with fillfactor = 90 on [primary] ) on [primary] go
insert into Test (code, prime) values ('AVA', cast(1 as bit)) insert into Test (code, prime) values ('BUS', cast(1 as bit)) insert into Test (code, prime) values ('BUS', cast(0 as bit)) insert into Test (code, prime) values ('BUS', cast(0 as bit)) insert into Test (code, prime) values ('CAR', cast(1 as bit)) insert into Test (code, prime) values ('CAR', cast(0 as bit)) insert into Test (code, prime) values ('RLW', cast(1 as bit)) insert into Test (code, prime) values ('RLW', cast(0 as bit)) insert into Test (code, prime) values ('RLW', cast(0 as bit))
select * from Test
I need to create a constraint on this table that will not allow me to have two rows that are prime for the same code. So the following insert statement should fail:
-- This should fail insert into Test (code, prime) values ('RLW', cast(1 as bit))
HiI am using SQL 2005, VB 2005I am trying to insert a record using parameters using the following code as per MotLey suggestion and it works finestring insertSQL; insertSQL = "INSERT INTO Issue(ProjectID, TypeofEntryID, PriorityID ,Title, Area) VALUES (@ProjectID, @TypeofEntryID, @PriorityID ,@Title, @Area)"; cmdInsert SqlCommand; cmdInsert=new SqlCommand(insertSQL,conn); cmdInsert.Parameters.Add("@ProjectID",SqlDbType.Varchar).Value=ProjectID.Text; My query is how to detail with dates my previous code wasinsertSQL += "convert(datetime,'" + DateTime.Now.ToString("dd/MM/yy") + "',3), '";I tried the code below but the record doesn't save?string date = DateTime.Now.ToString("dd/MM/yy"); insertSQL = "INSERT INTO WorkFlow(IssueID, TaskID, TaskDone, Date ,StaffID) VALUES (@IDIssue, @IDTask, @TaskDone, convert(DateTime,@Date,3),@IDStaff)"; cmdInsert.Parameters.Add("IDIssue", SqlDbType.Int).Value = IDIssue.ToString();cmdInsert.Parameters.Add("IDTask",SqlDbType.Int).Value = IDTask.Text;cmdInsert.Parameters.Add("TaskDone",SqlDbType.VarChar).Value = TaskDoneTxtbox.Text;cmdInsert.Parameters.Add("Date",SqlDbType.DateTime).Value = date;cmdInsert.Parameters.Add("IDStaff",SqlDbType.Int).Value = IDStaff.Text;Could someone point to me in the right direction?Thanks in advance
My goal is to select values from the same date range for a month on month view to compare values month over month. I've tried using the date trunc function but I'm not sure what the best way to attack this is. My thoughts are I need to somehow select first day of every month + interval 'x days' (but I don't know the syntax).In other words, I want to see
Select Jan 1- 23rd feb 1-23rd march 1-23rd april 1-23rd ,value from table
in sql server 2000 i know how to make primary key using enterprise manager i want to make one of the columns foreign key,how to do that using enterprise manager.and what is the difference between both.
In this table there are two columns, one called "company number" (NUMBER) and one called "company name" (VARCHAR). I have an index called agents_PK that are unique and indexes both columns with company number as first and company name as second in the column order.
But when I look at the data in the column company number its not unique, I find several rows with the same number.
