Problem With A Pretty Simple Query

May 7, 2008

Hello there, i'm pretty new to web development and i've come across this problem, so here's the case.
I got a videoclub database and i wanna show the movies categorized by the category that the movie belongs to. I got a table with all the categories (the table includes an ID and the name of the category),
and the movies table has movie data plus a category id field which is related with the categories table. Anyway enough with the background info here's the query i'm trying to use:
SELECT     MovieID, Name, Director, Category, Casting, Photo, Supplier, ReleaseDate
FROM         Movies
WHERE     (Category = @ Category)
The error i'm getting on the query builder is "Error in WHERE clause near '@'. Unable to parse query text.". If i aint wrong i'm supposed to use the "@" to indicate that its supposed to get data from a control. Anyway thats the prob, any help would be really apreciated.
P.S. The control i'm using is a dropdownlist that shows the categories names and has as a value the category id, so there isn't a variable miss match error as much as i know.

Need Help With Stored Proc. Pretty Simple For An Experienced Person

Sep 6, 2007

Can someone help me rewrite this query? Basically I need to check if the name stored in "CustomerName" already exist in the table "Renter". If it does not then I ncan insert the new customer name
into the data table "Renter". If the value in "CustomerName" already exists in the database, then I need to bypass the "INSERT" and somehow return a value indicating that the insert was not performed. How can I do this. Here is the
query I currently have for performing the insert.
CREATE PROCEDURE [dbo].[VacancyGet]
(
@CustomerName nvarchar(100),
@ClientCode nvarchar(10)
)
AS
INSERT INTO Renter
(
CustomerName,
ClientCode,
)
VALUES
(
@CustomerName,
@ClientCode,
)

Query Governor Pretty Useless?

Aug 17, 2007

I know that the query governor works off of estimated query plans, but the estimation is usually so far off from reality that it might as be generating a random number to determine whether a query should run.

Right now I have query governor set at 300. I've been able to run queries that take more than 10 minutes without any complaint from query governor.

What's really annoying though, is that it has also blocked queries that take less than a second to run. It blocked a query for having an estimated executing time of 338 seconds. When I set the limit up to 400, the query ran virtually instantly.

Is this just how query governor is suppose to work? Is there any way to make it work better?

This Is Probably Pretty Easy....

May 24, 2007

Hey guys, I'm new to reporting services and I just need to throw together a report that references multiple datasources. I can query up all my info individually, but I need to write a query that says,



Select ProductName,ProductId from datasource 2

where ProductId = @ProductIdFromDataSource1



I can get this to work, but if my query from datasource 1 returns 10 productID's, this will only return the productname from the first ProductID, 10 times. I believe that's because I'm using the First() aggregate function. Is there another function I can use that doesn't do that, or some way I can reference each field individually?



Just to clarify a little more, here's what I want:






Code Snippet

Product ID (ds 1) ProductName (ds 2)

------------------------ ----------------------

11 A

12 B

13 C

123 D



and here's what I'm getting right now:




Code Snippet

Product ID (ds 1) ProductName (ds 2)

------------------------ ----------------------

11 A

12 A

13 A

123 A



Thanks!

TimeStamp To Pretty Date

Dec 5, 2007

Good Morning,

Hate to sound so dumb, but, it's been years since I've done any SQL programming and I was bad at the time!

What is the code for taking my time stamp 2007-02-09 10:15:02.000 and just displaying the date as 02/09/2007?

Do I use variables? Are they set up before my select statement? Can anyone suggest a really good, easy, very explanable SQL (that will work in SQL Server) progamming book?

Thanks so much!

Help With A Simple Query

I am trying to make a single display page for an author's books.the books page only displays books of a type "type" (novels, non-fiction, etc)I would like to make it so that it can also show all books if "type" isn't selected.  I THOUGHT the string would look like this: <asp:SqlDataSource ID="SqlDSBooks" runat="server" ConnectionString="<%$ ConnectionStrings:csK2Reader %>"
SelectCommand="SELECT * FROM [Books] ( If @Type <> "" then WHERE ([Type] = @Type)) ORDER BY [SortDate] DESC"> But it doesn't seem to want to work.  I get a "server tag is not well formed" error.

Simple SQL Query -- Perhaps You Can Help

May 28, 2006

I hope it's considered appropriate to post a SQL query question here; it's not I'll gladly post this question elsewhere.  That having been said, I've run into a simple but quite tricky SQL query and was wondering if the community might be able to help.  Here's what's going on:
I have a "Documents" table.  Let's call it DI have a "Benefits" table.  Let's call it B.There is a many-to-many relationship between D and B so I have a third table to store the relationships.  Let's call that table BD.
When I create a document it creates a row in D.  Let's call that D1, D2...DN.  When I create a benefit it creates a row in B.  Let's call that B1, B2...BN
When I associate a document to a paritcular benefit, let's say that if D1 and B2 are associated, that I created row B2-D1 in my BD table.  Now here's what my challenge is.  Suppose I have these entries in my tables:
D: D1, D2, D3B: B1, B2, B3
Table BD:B1-D1B2-D1B2-D2
When the user goes to add documents to benefit B1, I want to show the user only documents that are not yet added to B1.  In this case, I want to show the user D2 and D3 but not D1 since that one's already added.  How do I write a SQL query to do this?
Here's what I've been using, but it shows too many results (e.g. included D1, D2, D3)
SELECT D.*, BD.*FROM Documents AS d LEFT JOIN rel_BenefitsDocuments AS bd ON d.doc_id = bd.doc_idWHERE (benefit_id <> @benefit_id OR benefit_id IS NULL)
Any thoughts?

I can't think of a way to get rid of the function call in the WHERE clause.
Is this actualy a problem ?

Simple Query

Jan 7, 2005

This should be easy, I'm just having a brainfart at the moment, can't remember how to do this:

Say I have a bunch of records in a table, with an ID field as Key. I want to return the count of times each ID shows up, so for the following example data:

Code:


-----
| ID |
-----
| 1 |
| 2 |
| 1 |
| 4 |
| 1 |
| 4 |
------


Would return something like:

Code:


----------------
| ID | Count |
----------------
| 1 | 3 |
| 2 | 1 |
| 4 | 2 |
-----------------


This should be obvious but for some reason I can't see it.

When this is done I'm going to join in another table to get a name based on the ID with the highest count. I believe it's faster to do a TOP 1 here rather than after the join, but I want to verify that while I'm at it also.

Simple SQL Query

Sep 19, 2005

Hi folks,

I am a complete newbie to SQL. I have a simple query to make in SQL, but I'm not being able to construct the statement properly. I've already tried googling this info, but with little luck. If someone could help me here, I'd be very thankful.

The problem:

I have a table with a list of questions. All questions have a serial number. The query has to return whether a particular question is the last one in the table or not (according to serial no.)

Logically, this is the query -


Code:


select islast = 0
if count(*) from question where serialno > $serial != 0
else
select islast = 1;



The '$serial' part will get replaced dynamically before query execution through another program.

Any idea how to code this in valid SQL? I would like to make it a simple statement and not a stored procedure. Thanks.

What Should Be A Simple Query

Feb 29, 2008

I'm having a bad day as I just cannot get a query to work and its doing my head in and it should be a simple query.

I'll try and explain what I need.

Have a simple query with one join, this is it so far:

SELECT DISTINCT Replace(StaffName,'''''',' ') AS StaffName,OutReason,OutStartDate
,OutEndDate,OutStartTime,OutEndTime,OutID
FROM vwOutOfOffice
LEFT OUTER JOIN vwStaffList ON OutUser=StaffID
WHERE OutComplete=0

What I'm having trouble with adding to the WHERE is as follows, I need a list of Staff who are out of the office based on the various criteria:

Example
Current date=29/02/2008
Current time=14:00

Start date---End Date----Start Time--End Time--Should Appear
27/02/2008--28/02/2008--09:00------17:00-----No (because of date)
28/02/2008--03/03/2008--08:00------17:00-----Yes
28/02/2008--29/02/2008--17:00------17:00-----Yes
29/02/2008--29/02/2008--12:00------14:00-----Yes
29/02/2008--29/02/2008--14:30------17:00-----No (because of time)
02/03/2008--02/03/2008--08:00------10:00-----No (because of date)

There may be others I've missed but as long as the dates combined with the times match correctly I need the records to appear.

Please help before I end up putting my head through the monitor.

Hello,

You probably seen this Q before but I have no idea what to search and and therefor any direction would be appreciated.

I have three columns table, two are int and one is datetime (for sorting). I would like to query all values witch are unique within the two integers, however, in some cases data looks like this:
int1 = 1
int2 = 2
and another record like:
int1 = 2
int2 = 1

this pair should be considered as a duplicate and second record should not come with the results set.

Any suggestions?

Help! Should Be A Simple Query

Mar 19, 2008

Hi I've got what should be a simple query but I'm not sure how to write it.

I have a table which holds employee assignments to positions, which holds historical data.

Eg:

ID EmployeeID StartDate PositionID
--- ---------- --------- ----------
1 7663 23/1/2007 234
2 7663 28/6/2007 272
3 7663 1/02/2008 983
4 81212 2/03/2008 2888


Now, what I'm after for each employee is their current position based on the highest "StartDate" for that employee.

So from the above table I want the results:


3 7663 1/02/2008 983
4 81212 2/03/2008 2888


Can anyone help? Do I need a Group By? That clause always confuses me!!!

Thanks!!!!

As you can see from the above example, I mayhave hundreds of the same stock code with different dates so I thought thatthe following query would work:select STOCKCODE, MAX(TRANSACTIONDATE) as 'LastOrderDate'from STOCKTRANSwhere STOCKCODE = 'IVP' and TRANSACTIONTYPE in (1,8)But it doesn't.NOTE: the reason for the transaction types of 1 and 8 is because these arethe types I want. The other types are used for credits, returns, etc.First of all the above, brings me back loads of rows when all I want is:IVP 11-8-04 << this being the last date of order for this stock item.Just as a test I removed the STOCKCODE out of the select and found that Idid get my one liner, but for some reason I was only getting the last datefor transaction types 1 only - not the last date for a combination of 1 and8 transactions.Can you help??Many thanksRgds Robbie
