Need Help With Figuring Out A Particulart SELECT Statement
Oct 25, 2006
I have 3 tables, Items, Brands and Categories. Brands and Categories consists of a primary key as well as the Brand/Category name.
Items has a bunch of columns as well as two foreign key fields, one for Brands and the other for Categories.
I want a SELECT statement that would select each Brand(id and name) as well as the associated categories for each brand (i want this info the menu control)
if this was a one-to-many relation, i wouldn't have had any problem... but since this is basically a many-to-many relation, i just can't figure it out

Here's what's going on. I have a 2 computers (x & y) running SQL2000. Ibacked up a copy a DB from x and restored it on y. I have a Stored procthat runs in under 2 seconds on both x & y when running it throughAnalyzer, but when I call this stored proc running it throuhg my C#winforms app (running on computer z) it takes over 3 minutes oncomputer x and under 10 seconds on y.This stored proc does have a select clause as part of the where clause,but again it works fine on y.I've check the indexes and that looks good and I just did a restore ofthe database so they should be identical. And I don't think it's aperformance issue because the rest of the app runs actaully a bitfaster on x.The plans do have differences. Specifically with a mention ofParallelism in the fast one.Here are the plans:X (slow):|--Sort(DISTINCT ORDER BY:([r].[GuestId] ASC, [g].[GuestNote] ASC,[Expr1005] ASC, [g].[Email] ASC, [g].[Phone1] ASC))|--Compute Scalar(DEFINE:([Expr1005]=[g].[LastName]+','+[g].[FirstName]))|--Filter(WHERE:(If ([Expr1003] IS NULL) then 0 else[Expr1003]>=2))|--Nested Loops(Left Outer Join, OUTERREFERENCES:([r].[GuestId]))|--Hash Match(Inner Join,HASH:([g].[GuestId])=([r].[GuestId]),RESIDUAL:([r].[GuestId]=[g].[GuestId]))| |--Clustered IndexScan(OBJECT:([Restaurant].[dbo].[Guest].[PK_Guest] AS [g]),WHERE:(len(isnull([g].[Email], ''))>6 AND charindex('@',isnull([g].[Email], ''), NULL)>1))| |--Clustered IndexSeek(OBJECT:([Restaurant].[dbo].[Reservations].[PK_Reservations] AS[r]), SEEK:([r].[RestId]=1), WHERE:([r].[Date]<='Jan 1 2005 12:00AM'AND [r].[Date]>='Jan 1 2003 12:00AM') ORDERED FORWARD)|--Hash Match(Cache, HASH:([r].[GuestId]),RESIDUAL:([r].[GuestId]=[r].[GuestId]))|--ComputeScalar(DEFINE:([Expr1003]=Convert([Expr1011])))|--StreamAggregate(DEFINE:([Expr1011]=Count(*)))|--IndexSpool(SEEK:([r2].[GuestId]=[r].[GuestId]))|--Clustered IndexScan(OBJECT:([Restaurant].[dbo].[Reservations].[PK_Reservations] AS[r2]))Y (Fast):|--Parallelism(Gather Streams)|--Sort(DISTINCT ORDER BY:([r].[GuestId] ASC, [g].[GuestNote]ASC, [Expr1005] ASC, [g].[Email] ASC, [g].[Phone1] ASC))|--Parallelism(Repartition Streams, PARTITIONCOLUMNS:([r].[GuestId], [g].[GuestNote], [Expr1005], [g].[Email],[g].[Phone1]))|--Compute Scalar(DEFINE:([Expr1005]=[g].[LastName]+','+[g].[FirstName]))|--Filter(WHERE:(If ([Expr1003] IS NULL) then 0else [Expr1003]>=2))|--ComputeScalar(DEFINE:([Expr1003]=Convert([Expr1013])))|--Hash Match Root(Right Outer Join,HASH:([r2].[GuestId])=([r].[GuestId]),RESIDUAL:([r2].[GuestId]=[r2].[GuestId]) AND([r2].[GuestId]=[r].[GuestId]) DEFINE:([Expr1013]=COUNT(*)))|--Parallelism(RepartitionStreams, PARTITION COLUMNS:([r2].[GuestId]))| |--Clustered IndexScan(OBJECT:([Restaurant].[dbo].[Reservations].[PK_Reservations] AS[r2]))|--Hash Match Team(Inner Join,HASH:([g].[GuestId])=([r].[GuestId]),RESIDUAL:([r].[GuestId]=[g].[GuestId]))|--Bitmap(HASH:([g].[GuestId]), DEFINE:([Bitmap1014]))||--Parallelism(Repartition Streams, PARTITION COLUMNS:([g].[GuestId]))| |--Clustered IndexScan(OBJECT:([Restaurant].[dbo].[Guest].[PK_Guest] AS [g]),WHERE:(len(isnull([g].[Email], ''))>6 AND charindex('@',isnull([g].[Email], ''), NULL)>1))|--Parallelism(RepartitionStreams, PARTITION COLUMNS:([r].[GuestId]),WHERE:(PROBE([Bitmap1014])=TRUE))|--Clustered IndexSeek(OBJECT:([Restaurant].[dbo].[Reservations].[PK_Reservations] AS[r]), SEEK:([r].[RestId]=1), WHERE:([r].[Date]<='Jan 1 2005 12:00AM'AND [r].[Date]>='Jan 1 2003 12:00AM') ORDERED FORWAny ideas of what I can check for?Thanks for any help.

Hi, I have a users table in my SQL Server database. Now, I am looking to create a table (or multiple tables) to allow users to post their weekly events, meetings, activities, and accomplishments to the database. Each Monday morning, each user will enter their new schedule for that week and the previous week's entry will be archived in the database. My question is: what would make more sense? Should I create one big table that would have the following columns:
- Week Number (the current week number in the year)
- User ID
- Events
- Meetings
- Activities
- Accomplishments
And each user would have one row in the database per week.
OR should I create 4 separate tables named Events, Meetings, Activities, Accomplishments. Each of these tables would have the following columns: (for instance, the Events table would contain:)
- eventID (auto incremented number)
- userID
- weekNumber
- event_description
Each time a user adds a new event to their schedule, a new row in the Events table is created. Each time a user adds a new accomplishment, a new row in the Accomplishments table is created. etc., etc.
Which approach seems to make more sense and would be easier to maintain? Also, which one would conserve database space better and result in faster querying.
Thanks, Dave

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

I am using three tables in this query, one is events_detail, one is events_summary, the third if gifts. The original select statement counted the number of ids (event_details.id_number) that appear per event_name (event_summary.event_name).
Now, I would like to add in another column that counts the number of IDs that gave a gift who attended an event that were also listed in the event_ details table. So far I have come up with the following. My main issue is linking the subquery properly back to the main query. how to count in the sub-query and have the result placed within the groups results in the main query.
SELECT es.event_name, es.event_id, COUNT(ed.id_number) Number_Attendees,
(
SELECT COUNT(gifts.donor_id) AS Count2
FROM gifts
WHERE gifts.donor_id = ed.id_number
) subquery2

Hi All,
Can some one point me in the right direction in how to construct my SQL query within my cursor?
I Have got a cursor which i am using to iterate through a table, What i am trying to do is in my statement(used to open the cursor) is compare 2 tables (the one which my cursor is iterating) to see if there is a matching row in the other table (using both tables ID's Like So:
SELECT column_List
FROM Table1
WHERE Table1_id = Table2_id
so for each row my cursor checks if there is a corresponding match in table2... but i would like to write to an error log
and do other statements if there is no match
how do i add this condition to my statement either using an if...else statement proceeding to the next row?
here is the statment i attempted to write:
SELECT column_List
FROM table1
WHERE
Table1_id = Table2.id
now i want to incoporate the statements below into the statement above as a condition when table1.id <> table2.id
IF table1.id <> table2.id
BEGIN
SET @DebugMessage = 'data not live.'
RAISERROR (@DebugMessage, 16, 1) WITH LOG
END
essentially what i am trying to sayin my statement is:
go to the first row
check if it has a match in table 2,
if there is no match execute a number of statements such as error loging e.t.c
go to the next row
repeat the previous statements
...i also looked through some Case...When statements am just not sure how to put in the condition
thanks in advance

This is what I have in the first column 0 - MM/dd/yyyy 12:00:00 AM
This is what I want - MM/dd/yyyy

I want to use it in a select statement similar to:
select customername, @country=(exec getCountry @ipaddr=customer.customeripaddress) from customer
I'm intend to receive a list of customer names and the 2 char result of GetCountry based on the customeripaddress field of the customer table. What I get is a syntax error near Exec and then another one near '.'

eThe EventDateTimes table can contain multiple records that match with the Events table. Is it possible to adjust this query so that only one record is returned per event? Right now, if there are like 3 records in the EventDateTimes table that match the UID in the Events table, then I will see the same event name outputed 3 times. Hope it makes sense...
