Help With A Confusing And Advanced Query - If Exsists?
Nov 14, 2003
Ok,
I need to select a list of products based on a complex criteria. First off, here is a list of the tables I am using and their function.
Dbo.Products – This table holds product names and information.
Dbo.Products_Attributes – This table holds a list of attributes for each product. It has a many to 1 relationship with Products. This table holds only 2 fields – ProductID and AttributeID
Dbo.Customers – This table holds basic customer information and some of the needed criteria for the product search.
Dbo.Customers_Attributes – This table contains a list of attributes that the customer needs in his/her products. This table has a many to 1 relationship with Customers and only has 2 fields, CustomerNum and AttributeID
Dbo.Attributes – This table contains all of the different attributes possible for our products to have. Each can be used by a customer when choosing criteria.
Background: Each attribute is a True / False. Either they want that attribute, or they do not care if they get it or not. This is where the hard part comes in. If a particular attribute is listed as needed in dbo.Customers_Attributes, then I do not want any records pulled from Products that DOES NOT have this attribute. On the other hand, if the attribute is NO listed in the customers_attributes list, it is assumed that the customer wants it. In other words, if there were NO attributes in the customers_attributes list, ALL products would be returned. Attributes listed in the customers_attributes table are “required� (no product will be returned that does not have what is in the list).
I hope I was clear enough… I had to change the table names a functions slightly because of some stupid policy about giving out too much proprietary information here.
If any of you know how to do the above with a subquery of some kind, please let me know.
Hi Guys,This is my Problem.A table contain following desing for handling different level of categories, bu it is dynamic int_categoryid,int_parent_categoryid,int_categorylevel,str_categoryname,bit_activethatall.I want to list data from table as following ordercategorry_parent11 category_child12 category_child13 category_child23 category_child22categorry_parent21.............................................................................................like this..ie we can insert parent category and sub category to n level dynamically without adding a new tableplease mail me for another clarification....please help meregardsAbdul
I am looking to query one table where the matching information in the related table needs to be a subset of the data - but not always a complete set (and there may be added information in the related table). For example, if I have a table of Albums and I want to match songs to albums as follows:
Albums
Name CHAR_TYPE CHAR Rock guitarists Genre Rock Rock guitarists Instrument Guitar Great Guitar Instrument Guitar Rock and Blues Genre Rock Rock and Blues Genre Blues
Songs
Name CHAR_TYPE CHAR Purple Haze Genre Rock Purple Haze Instrument Guitar Purple Haze Artist Hendrix Red House Genre Blues Red House Instrument Guitar Red House Artist Hendrix Stairway to heaven Genre Rock Stairway to heaven Instrument Guitar
For this query, the results should be
Album Song Rock guitarists Purple Haze & Staiway to Heaven Great Guitar All 3 Rock and Blues All 3
Everything I've tried either incudes extra songs (Rock Guitar includes Red House) OR Eliminates entire albums (everything else works, but rock and Blues produces no results
I want to query a database through a ASP.NET page and I want to set the page up like an advanced search page would look. My question is, how do I write the stored procedure and/or what value do I pass from ASP.NET to accomplish null or blank values. For instance, if someone wants to query by TRIP id and not vehicle ID then how do I write the where claue?
I have the following figured out, however what I want to do is almost come up with a new column based on if the row actually exists in the employeeeval column: SELECT e.DeptID, e.LastName + ', ' + e.FirstName AS EmpName, e.EmployeeID, u.UserName FROM Employee e LEFT OUTER JOIN EmployeeEval ev ON e.EmployeeID = ev.EmployeeID LEFT OUTER JOIN [User] u ON u.Department = e.DeptID WHERE (u.RoleID = 'supervisor') AND (e.CompanyID = @CompanyID) AND (e.FacilityID = @FacilityID) AND (ev.PersonalScore IS NULL) ORDER BY e.DeptID, e.LastName so in my select I want to add something like ev.approved which then that brings back either Null or 0. Then based on that create a variable to bring back as a string and if it = 0 make my string say 'In Progress' and if it's Null, say 'Not Started'. I would imagine I would need a Declare @Status nvarchar(15) --- but I get lost after that b/c wouldn't I need some sort of way to count throught the rows of my result set and do an IF statement? I can't quite figure this process out, after numerous attempts.
I want to run a query overnight through the SQL agent using osql. However I need to turn off the print header option that you normally turn off through the advanced options tab in the Query Analyzer. Does anyone know if this is possible?? Many Thanks in advance..
SELECT item.name AS name, t15.f167 AS start, t15.f168 AS end, t15.f180 AS organizer FROM item, t15 WHERE item.row_id = t15.id AND t15.f167 > getDate() UNION ALL SELECT item.name AS name, t30.f221 AS start, t30.f222 AS end, '<a class=kalender_link href=http://www.xxx.no/default.asp?V_ITEM_ID=' + item.id + '> KAN < / a > ' FROM item, t30 WHERE item.row_id = t30.id AND t30.f221 > getDate() ORDER BY start DESC
The problem is the organizer field. I need to generate an url, but I get all sorts of problems with data types, ie. you can convert an int into ntext.
So the question is basically, how do I get the following to work:
'<a class=kalender_link href=http://www.xxx.no/default.asp?V_ITEM_ID=' + item.id + '> KAN < / a >'
Hi,This is my basic sql shape query:------------------------------------------------------------SHAPE {select * from tbl1}APPEND({SELECT * FROM tbl2 where field1=1} AS RS2 RELATE field TOfield)------------------------------------------------------------With this query i get a RecordSet (RS1), who handle all the recordsfrom table tbl1, and a secondary RecordSet (RS2) who handle all therecords from table tbl2, who applies to the criteria that field1=1.It is possible that RS2 will be empty (zero records) since there is norecord in tbl2 who applies to that criteria.My wish is to design a query, that will collect only the records fromtbl1, that will have records from tbl2 who applies to the criteria -that RS2 won't be empty !I want to influence on the main part of the query (RS1), through thecriteria that is being used in the secondery query (RS2).I hope that my question is clear enough. thanks !
Dear Expert,I have 2 tables as the following,Table : ProductColumn : ID, Code, NameTable : TrxColumn : Trx_ID, Trx_Date, Product_IDHow can perform the following query in MSSQL or is there any other wayto perform the same query ???

THIS LOOKS LIKE A LOT BUT I JUST WANTED TO GIVE ALL INFORMATION NEEDED FOR YOU TO EASILY ASSIST ME. I am not good with SQL so please bare with me. I will give a dumbed down table for us to work with:timestamp - DATA1 - DATA2 - MAXVALUENEEDED - DATA32006/8/12 12:00 123 125 1289 121 2006/8/12 12:05 124 128 1291 1232006/8/15 12:00 130 128 1190 1242006/8/15 1:00 131 127 1196 123 The columns labeled DATA do not really matter. The only important ones are timestamp and MAXVALUENEEDED but I do need the query to return all columns. What the query has to do: The query needs to find the MAX of MAXVALUENEEDED for a given DAY. Example Output- 2006/8/12 124 128 1291 1232006/8/15 131 127 1196 123As you can see the MAX values were grabbed for each given day and the unique records were returned on a per day basis. My current SQL Query is: SELECT CONVERT(varchar, timestamp, 101) AS Time, CONVERT(int,LV50AEPM_AMPS_A_VAL0) AS AMPS_A, CONVERT(int,LV50AEPM_AMPS_B_VAL0) AS AMPS_B, CONVERT(int,LV50AEPM_AMPS_C_VAL0) AS AMPS_C, CONVERT(int,LV50AEPM_KVA_TOT_VAL0) AS KVA_TOTAL, CONVERT(int,LV50AEPM_KW_TOT_VAL0), CONVERT(int,LV50AEPM_VLL_CA_VAL0), CONVERT(int,LV50AEPM_VLL_BC_VAL0), CONVERT(int,LV50AEPM_VLL_AB_VAL0) FROM Table_1 T1 WHERE CONVERT(int,T1.LV50AEPM_KVA_TOT_VAL0) = (SELECT MAX(CONVERT(int,T2.LV50AEPM_KVA_TOT_VAL0)) FROM Table_1 T2 WHERE CONVERT(varchar,T1.timestamp,101) = T2.timestamp) ORDER BY Time ASC The problem is it only returns the max value for one day instead of all days. Can anyone help me correct this? Thanks in advance for your help.
I have an application that connects to a db running on SQL server 2000. I want the user to be able to do a google-like search, which returns all records containing all given keywords specified by the user in any of the fields, example:
Table has the fields: id, fruit, color
User enters: apple pear green
The query should return all records that contain apple AND pear AND green in any of the fields.
Now I do it like this:
SELECT * FROM table WHERE (fruit LIKE '%apple%' OR fruit LIKE '%pear%' OR fruit LIKE '%green%') AND (color LIKE '%apple%' OR color LIKE '%pear%' OR color LIKE '%green%')
this query works fine, but since my actual table contains about 10 fields that have to be searched, the query get's quite huge, especially when 2 or more keywords are given.
Question: is there an easier way to achieve this?
(this is what my query actually looks like, using the keywords dekker warmenhuizen 0226:)

This is my simple table I need a query that will identity the ID's that are missing the group "b" but I don't want ID 1,2,3 to come up because they are part of a and b. I just need to see anything missing only "b" but not if it's part of a and b.
query should reveal answer should be missing the group b KEYID 7 4 8 5
I tried the NULL search but since the records don't exist it cant find a null. I am writing a query to identify the missing ID without B but exclude ID that are part of A and B
SQL Sever 2012, I have a table where I store data related with a Log, the columns of the table are three, IDTable, DateLog and CountLog, the column CountLog is a cumulative value, each new rows can increment this value, my query will receive two parameters related with the Date,  @dateFrom and @dateTo, with this information is necesary to get the diff between two months, for example:
CREATE TABLE MyTable (  IDTable INT IDENTITY NOT NULL,  DateLog  DATE NOT NULL,  CountLog INT NOT NULL )
[code]....
In this case I need to apply a filter with the Dates:
@dateFrom ='2014-01-01', @dateTo   ='2014-04-28'
But according with this filter I need to limit the results only for this period between the date, but I need that the first month (January 2014) take the information of the max value from previous month even not included in the filter, in this case the results will be the next:
Id     MonthYear    Diff 1       Jan2014    5 2       Feb2014    3 3       March2014  0 4       April2014    5
With the results, for the first mont (January) is, according to the range of times, January is the lower limit,the last cumulative value of CountLog before the first month of the range  was 2 (December 2013), the max value of the CountLog for this first month was 7, the diff is 7-2 equal to 5 , in the case of the next month (February) the max value of the CountLog was 10, the diff is 10 - 7 equal to 3 and this way.

This is a fairly detailed problem, so this will be a long post... I do appologize. I have been agonizing over this now for over a week and cannot find a viable solution. Hopefully one of you can help.
First off, I work for a realestate company, and this query will display a list of properties based on a number of different criteria and criteria types. There are multiple tables involved:
dbo.Prop: Property Database. Holds basic info about each property
dbo.Prop_Features: holds all the features (such as Pool, Carpet, Drapes etc) for each property. The only information stored in this table are PropID and FeatureID (PropID being the Identity of the Prop table, FeatureID being the Identity of the Features Table)
dbo.Features Holds information on each possable "feature" in the system.
dbo.Members Holds basic information and criteria for each of our members.
dbo.Members_Features This table holds the MemberID and FeatureID where members have chosen one ore more features to be used for criteria when searching for a property.
Ok, now... That said, here is my problem. The query I had written (by a professional hired thru Robert Half Technologies) takes over 30 seconds to execute. I will post a copy of that SP below. This is unacceptable. We have to process thousands of these per hour, and a 30 second process time is very bad. Can any of you give me a idea of how to better approach this problem?
In the code below, you will notice there are other tables I did not mention - they are not important. The Speed problem is surrounding a single function, which I will mention below.
CREATE PROCEDURE dbo.Member_Get_List ( @MemberID Int, @UpdatesOnly Bit

This function is the cause of the speed problem, methinks. When run alone, it takes 29 seconds to process with the same MemberID that takes about 33 seconds to process completely (the whole Proc). This function simply returns a list of comma delimited features for each property, for displaying on a customer list. Here is that function:
CREATE Function dbo.Prop_Get_Feature_List_Fun (@PropID int) RETURNS Varchar(3500)
AS BEGIN
Declare @FeatureList Varchar(3500)
select @FeatureList = Coalesce(@FeatureList + ', ', '' ) + F.FeatureName FROM Prop P
INNER JOIN Prop_Features PF
ON P.PropID = PF.PropID
INNER JOIN Features F
ON PF.FeatureID = F.FeatureID
WHERE
P.PropID = @PropID
ORDER BY
F.FeatureName
Set @FeatureList = isnull(@FeatureList,'Please call for features.')
RETURN @FeatureList END
Now, I know I probably gave lots more information then needed to solve this issue - but its better to have too much then not enough.
Any help at all in speeding up this function or describing another way to do this would be most appreciative.
I graduated from college about three years ago and have been working as a programmer using MS SQL 2000 and even though I've learned a TON in these past three years I know there is tons more I can learn.
Because my company uses Microsoft SQL Server 2000 I'd like to focus on that, but anything ANSI-SQL is perfectly fine.
So... what are some good books on SQL query optimization and other advanced SQL topics?
select distinct advert.advertiser_id, advert.advert_id, advertiser.fullname from advert join advertiser on advert.advertiser_id = advertiser.advertiser_id where category = @category GO
Anyway, The following two select statements return exactly the same results, and utilize exactly the same server resources to run (according to the generated explain execution plans).
The where clause(s) in each are designed to exclude rows that are "empty" according to the designer of the db (don't ask...*rolleyes*).
My question is this...which way would y'all code the select. I have always been "trained" to NOT use negative logic (heh,heh,heh), so originally wrote the select (which, in effect, translates to "get me everything but the empty rows") as:SELECTOSID AS OSID, [Year] AS QtrYear, 1 AS QuarterNo, QEPS4 AS EPS, QSales4 AS Sales, QInc4 AS Income, CONVERT(varchar(10), QDate4, 101) AS EarningsReportDate FROM dbo.RSMsi WHERE ((QEPS4 <> 0.001 AND QEPS4 <> 0.0) OR QSales4 <> 0.0 OR QInc4 <> 0.0 OR QDate4 <> '01/01/1900')but in retrospect, I think that's an ugly where clause, and think folks will look at it and think "WTF??? what does THAT mean?". So, I re-wrote the select as if it was looking for the empty rows, then slapped a "NOT" in front of the where clause to negate it in order to STILL say "Get me everything, but NOT the empty rows", as follows:SELECTOSID AS OSID, [Year] AS QtrYear, 1 AS QuarterNo, QEPS4 AS EPS, QSales4 AS Sales, QInc4 AS Income, CONVERT(varchar(10), QDate4, 101) AS EarningsReportDate FROM dbo.RSMsi WHERE NOT ((QEPS4 = 0.001 OR QEPS4 = 0.0) AND QSales4 = 0.0 AND QInc4 = 0.0 AND QDate4 = '01/01/1900')whatcha think y'all? It's a style issue, I know...just curious for consensus' sake. Thanks!
I have 5 tables, the first 4 are responsible for getting wines with all their associated info:
Areas - Regions - Wineries - Wines
The last table is an artwork table, and both wineries and wines can have artwork associated with them. How do I integrate a join on the 'Artwork' table for both wineries and wines, taking into account that sometimes (for a single record) there is art for both winery and wine, sometimes for one, sometimes there is none?
I think I understand the 'ON' statement, for instance:
Wineries LEFT JOIN Artwork ON Wineries.winery_id = Artwork.artwork_winery_id
'and'
Wines LEFT JOIN Artwork ON Wines.wine_id = artwork_wine_id
But how do I integrate that into the following SELECT statement?
I'm stuck trying to pull together what is for me a complex join statement. I have 8 tables following, and would like to figure out how to extract all users and roles (if they have any associated) when given a company and division. I have given a couple examples the way they should be output.
domainuser belongs to both domainAuditConfig and domainLookupConifg windows groups.
When domainuser logs in, he will have both AuditConfigRole and LookupConfigRole roles.
If I reconfigure the above using loginless user, how can the user takes on both roles at the same time?
It seems to me that the user needs to know what role he needs at the time and run the appropriate EXECUTE AS command. Is this true? I can see the benefits of using EXECUTE AS when we are testing our code. But in a production environment, how can the end user know who to EXECUTE AS?
Does it only make sense to use EXECUTE AS from within an application?
I have a gridview that is very basic and list name, address, ......., and a URL. If I have this url in the database I have no problem http://www.lubbockisd.org/earlychildhood/ yet when I place this URL http://www.lubbockisd.org/erlychildhood/stubbs.htm It triggers this error on my localhost server and my production server. Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.ConstraintException: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. I've made changes to datatypes with no success, made sure my length of data type was set long enough with no success. Which datatype is best for a URL in sql express? Any ideas why this happens with such a minor change?
Hi,I have a table for storing my picture albums here it is:CREATE TABLE [UserAlbum] ( [ID] [int] IDENTITY (1, 1) NOT NULL , [UserID] [int] default(0) , [AlbumName] [nvarchar] (100) NULL , [Audience] [int] default(0) , [Date_added] [smalldatetime] NULL , CONSTRAINT PK_CmmNet_userAlbum_ID PRIMARY KEY CLUSTERED ( ID )) ON [PRIMARY]GO it has a field called "audience" as the name defines i want to choose who will see my albumsit is integer and as follows:0 value=everyone1=friends only2=private as i started to write a query for it i came into this problem: for exampleif i write SELECT * FROM UserAlbum where audience=1 then only friends can see the infowhat happens to everyone with value of 0?when i set it to 0, friends should also be able to see the info because it is set for everybody i noticed i should use "in cluase" like thisSELECT * FROM UserAlbum where audience in ('0','1') > so in this way both everyone and also friends can see the info or maybe i should add 3 different fields for private,public,friends it seems to be simple but at the same time harddoes anyone have a suggestion?

ENDWhat's cause the crash are the quotes around @eventdate. However, without them, it doesn't return all the rows (if any) and if I have them in, I get this error. The odd thing is that when I copy and paste one of the SELECT statements into the VWD sql window and replace the variables with the same values I'm using at runtime, everything runs fine.Anyone have any ideas?Thanks in advance,--Joel
Hi, I have a SQL2k STD with SP3 installed. Currently, only one database db_XYZ is there. The server has been started up since 07/03/2003 16:00 pm. But in the sql server current log: "Starting up database 'db_XYZ'." info is spreading from that time (16:00 pm) to this morning 10:00am at an interval from every 1 minute to 4 minutes.
Why need to 'Starting up' this database so much times? This reminds me that this 'Starting up' is kind of 'abused' in many other servers. Any idea?
I've been looking on-line for about a day now and can't find what I'm looking for. I don't know much about ActiveX and even less about using it in a DTS package. If you guys could help me out be telling me what to use/give a few minimal examples I can figure the rest out. I just can't find enough info on the web to do what I want.
I'll describe what I've got, what I'm trying to do with it, and we'll see what you guys think.
What I've got: A table that stores To, Subject, MsgText, MsgHTML, and FileAttachment locations.
What I'd Like to do: Write out the info in the table into a text file and then copy it to the Pickup folder to be sent. Now, I know DTS has an e-mail task, but the Dynaprops/e-mail task are being flaky. The information in the E-Mail doesn't always seem to update like I'd like it.
How I was planning on doing it: Write an ActiveX script to Create the E-mail, store it in the DB, and then Write it out to the txt file to be sent.
I think this'd be a good way to do it, but then again I could be wrong. Maybe use something else? Please help. I could use it.
Ok, i have been trying to restore the company helpdesk server since our move at the start of the year and after it was sitting doing nothing for a good six months or so.
I finally got the server going (after extensive messing about on our test box), but i'll set out the scenario for you:
Test Server: XW4000 (win2k Advanced Server + SQL Server 2k) Main Helpdesk Server :BK_MAN5_INV (NT4 SP6 + SQL Server 2k) Client Machines: BK_CI_03006 and BK_CI_03010
Now for the problem. Both the test server and the main helpdesk server have been configured in the exact same way, and BK_CI_03006 has no problems connecting to either server. However, BK_CI_03010 can only connect to the test server and not the main helpdesk server.
We are planning on removing the test server as soon as this is sorted, but i have no idea why there is this problem with the machine.
If anyone can provide any input on this at all, i would be really grateful.
I am new to MS SQL coding and I am having a problem with date conversions. In PL/SQL, I could convert numeric months into character months in their own columns by using the DECODE function. An example would be:
In the Books on Line of MSSQL2000 In "Adding a Member to a SQL Server Database Role"
There is this "Note : When you add a Windows NT 4.0 or Windows 2000 login without a user account in the database to a SQL Server database role, SQL Server creates a user account in the database automatically, even if that Windows NT 4.0 or Windows 2000 login cannot otherwise access the database."
I mean how can anyone add a login to a database role without making the login a user of the database.:shocked: Also if it worked, a new fancy feature to add new logins??:eek: Plz help:S
After downloading and installing this tool, I'm confused. The documentation refers to a wizard, which I can't find in the Start menu.
Development team: Where is this wizard? This is a great idea that I'm certain many people can benefit from--- please make some better documentation, and give us a product that does what the documentation says.
