Let me start off by first saying im a newb. Ok, with that out of the way I
am trying really hard and boy have I learned a lot in the last little while
but I have a question i just can't seem to find a good answer to.
Lets say i have a table that simply stores how many times someone has logged
into a webpage. Is it better to store each login as a new record then count
the records or is it better to simply have one record that updates the total
value by incrementing that one field. I have read all manner of articles
and some say one way is better vs. the other but what I can't find is why?
If I knew why one way was better than another then I could make and educated
decision and choose the best way that is right for me. Is updating more or
less expensive then inserting? Does it matter and is a relevant question?
And before anyone comments on my use of all uppercase letters for my table
name I do this so that my table names stand out within the sql server
enterprise manager. In other words system tables are lowercase and my
tables are uppercase. People always seem to give me crap for this but never
back it up with a good explanation so far as I can tell its personal
preference? Am I wrong?
CREATE TABLE USER_METRICS
(
-- here i can select all the records and count them up.
ID INT IDENTITY(1,1) PRIMARY KEY,
Email VARCHAR(250)
);
-- Or this?
CREATE TABLE USER_METRICS
(
-- and of course here can i simply retrieve the value of Total_Logins
ID INT IDENTITY(1,1) PRIMARY KEY,
Email VARCHAR(250) NOT NULL,
Total_Logins INT
);

]First of all here is how i created my SQL database and established a connection in visual studio 05. I go into the server explorer and right click on the data connections node and and select "create new SQL database". A window then prompts me for a server name and data base name. Under server name I write "localhostSQLEXPRESS" and under data base name I put in whatever. This totally worked and the database was asigned the extension of .DBO I can now insert, select and delete information with some simple ADO coding. The only problem is that using this method makes it seamingly impossible to FTP my database onto my host server. I am aware that I can create a data base in the APP folder by simply right clicking it and selecting " new database". This would simplify the deploying process but I cant seem to establish a connection this way. Ive also noticed that when I use this method that it saves it as a .MDF instead of a .DBO. What is the difference? Why does my .DBO work but not my .MDF in my app folder? Im so confused over this issue that I am problably not even asking the right question. Bottom line is that I have a small web application with a .dbo database that works wonderfully in my isolated visual studio environment and I need a solution to deploy it on the world wide web. Please help with any information I would be very thankfull.

Hi all, I've recently created a shopping cart system that uses SQL Server on the backend. The shopping cart will add a record to a table called CartEvents each time anything happens, like view item, update, delete etc. anyhow, the site has been up for about a week now and that particular table has about 4200 records already, I project tens of thousands of records in that table, so how many records is too many records? Whats your experience with tables that have hundreds of thousands of records? How many records can SQL server handle and still perform well?
Im using windows xp sp2 and MS Sql server 2005 enterprise edition may b and im also havin sql server express previously when i installed sql server express it took server name on its own and i used to run queries using AdventureWorks database.. Recently i formated my desktop and again installed both the versions im having but neither is taking server name.. and i dint noticed what was the server name before.. im a student home user i just hav to query on adventurework databases on the same computer i cant afford to buy any servers.. so can anyone tell me how can i configure sql so that i can query !
I've been writing a few sql queries over the past few days, and would like to know what the difference is between:
website is null
website like ''
Becasue if they mean different things i want to know how to look them both up at the same time. Obv im after data that is blank or has nothing written in it.

I have a query that must return information for an invoice. It is not straight forward though. Some things need to be displayed from the if something else is happening... For example...declare @id int declare @chargeid int set @id = 1 set @chargeid = 9
declare @pp bit, @pages int, @pagefee money, @pagecharge money set @pp = (select perpage from tblmainfees where mainfeesid = @chargeid) if (@pp = 1) begin set @pages = (select pages from tblcharges inner join tblrequest on requestid = fkrequestid where requestid = @id) if (@pages > 0) begin set @pagefee = (select perpagefee from tblmainfees where mainfeesid = @chargeid) set @pagecharge = (@pages * @pagefee) end end ...
select @pagecharge as PerPageCharge
Or should I do some complex query with only one select?
Im a bit confused as to what is best. I have a web site built in c# web dev which utilises a data base. What is best practise ........... 1. To have one sql data source on one page and all other pages use that source. 2.. each page has its own source and connection string depending on its data requirements. 3..... have no source and use insert statements with stored procedures because most of my site extracts data from visitors rather than displaying data to them. If I have this right.......the data source is a copy of the data base that is available for use to the visitor or is it just part of the connection to the data base. My only gripe with the whole development process has been the discovery that I have learnt four ways of doing the same thing.......which in its self becomes confusing.. However one thing has stood above all else ........this forum richard

I'm working on an mini intranet site for a "University" type style. I have a table called "events" which stores information. One of my columns is "eventRSVP" which stores the employees ID's who click on the button, separated by a comma.
example: Quote: 1751,2179,1371,2314,1778,702,1607,798,2097 Would it be better to create a new table called something like "event_jn" and it has 3 columns.
I'm also redoing our whole intranet and would be doing a lot of these similar type id linking. So my other question is, the more tables I have, is it going to slow down the response time?

Hi, I recently modified all the messages with severity 15 and 16 to be logged in windows applications log... I then discovered that my Application is generating lots of errors of type:
Error: 16945, Severity: 16, State: 1 The cursor was not declared.
followed by
Error: 16955, Severity: 16, State: 2 Could not create an acceptable cursor.
I think this error is occuring since a lot, but I discovered it now because I recently modified which messages are logged (I added those with severity of 15 and 16).
This error is occuring everytime (one error every 3 minutes!!)... I dont know what part of my app is having trouble, i think its a bug of sql server... Does somebody know anything about this error?
SET @EventName = 'DIVIDEND' SET @Ticker = 'IBM' SET @Cusip = ''
SET @Filter = 'Name like ''' + @EventName + '%'' AND Ticker Like ''' + @Ticker + '%'' AND Cusip like ''' + @Cusip + '%'''
Select * from eventdatadetails where @Filter
I want to execute the above SELECT statement and the filters in the where clause should come from the @Fitler variable... but query analyzer gives an error. If i replace the data in the @Filter with the variable in the query, everything works fine ...
I'm very new to SQL. YOur help is appreciated. Ok system_user is the main table. All the CREATED_BY and LAST_UPDATED_BY columns in all tables are supposed to reference back to the system_user table. Anything with _TYPE (i.e. CONTACT_TYPE, ADDRESS_TYPE ) is supposed to map to common_lookup table.
Heres the error I get: ERROR at line 12: no mathiching unique or primary key for this column-list.
Heres where I I think I have the mistakes. Pks and FKs
Thank you.

I have a sql 2005 database on a server and I want to have a copy of that database on my workstation (running sql 2005 developer). What is the easiest way to do this ? We have DBGhost also.
