I am currently faced with developing a search function (ASP.NET 1.1
based user interface) to a database (SQL Server 2000 ), and I am
wondering how best to handle the logistics of it.
The search can take anywhere from one to 9 parameters. The search would be executed against three related tables.
The main problem, as I see it at this stage, is how to handle
parameters that have not been selected, it's easy enough to do a search
with all 9 parameters, but as soon as there is an unpredictable
variable number of search criteria, I just don't know how best to
handle this in a stored procedure for example.
I need a query to join 3 tables. Here is my setup: TABLEFields GroupsID, Name KeywordsID, GroupID, Keyword SearchID, Keyword
"Groups" and "Keywords" are linked one to many, with each group being assigned multiple keywords. "Search" holds a list of keywords that I want to search for. In particular, I need to find the groups that have ALL of the keywords in "Search" assigned to them (not just at least one). I've tried many different approaches, but cannot find a way to do this with a single query. All my attempts so far also return groups that only have a few of the keywords in "Search" assigned to them, but not ALL. Can anyone help? I am desperate to find a solution... Thanks!
I have web forms with about 10-15 optional search parameters (fields) for a give table. Each item (textbox) in the form is treated as an AND condition.
Right now I build complex WHERE clauses based on wheather data is present in a textbox and AND each one in the clause. Also, if a particular field is "match any word", i get a ANDed set of OR's. As you can imagine, the WHERE clause gets quite large.
I build clauses like this (i.e., 4 fields shown):
SELECT * from tableName WHERE (aaa like '%data') AND (bbb = 'data') AND (ccc like 'data%') AND ( (xxx like '%data') OR (yyy like '%data%') )
My question is, are stored procedures better for building such dynamic SQL clauses? I may have one field or all fifteen. I've written generic code for building the clauses, but I don't know much about stored procedures and am wondering if I'm making this more difficult on myself.
Hi!We have Sql Server 2000 in our server (NT 4). Our database have now about+350.000 rows with information of images. Table have lot of columnsincluding information about image name, keywords, location, price, colormode etc. So our database don?t include the images itself, just a path tothe location of every image. Keywords -field have data for example likethis:cat,animal,pet,home,child with pet,child. Now our search use Full-TextSearch which sounded like good idea in the beginning but now it have hadproblems that really reduce our search engine?s performance. Also searchresults are not exact enough. Some of our images have also photographer?sname in keywords -column and if photographer?s name is, for example, PeterMoss, his pictures appears in web-page when customer want to search "moss"(nature-like) -pictures.Another problem is that Full-Text Search started to be very slow when queryresult contains thousands of rows. When search term gives maximum 3000rows, search is fast but larger searches take from 6 to 20 seconds tofinish which is not good. I have noticed also that first search is alwaysvery slow, but next ones are faster. It seems that engine is just"starting" when first query started to run.Is there better and faster way to handle the queries? Is it better torebuild the database somehow and use another method to search than Full-Text Search? I don?t know how to handle the database other way when everyimage have about 10 to even 50 different keywords to search.We have made web interface and search code with Coldfusion. ColdfusionServer then take care of sending all queries to Sql Server.I hope that somebody have some idea how to speed up our picture search.--Message posted via http://www.sqlmonster.com
Good day all,I'm looking for suggestions on how to handle the calculating of scores for search results from data. Primarily if it would be best to calculating the score on the SQL server side or in the application's logic itself after the results have been retrieved? I already have an idea of the calculations I want to do which will be pretty simple, just a basic point system for containing all the queried terms and additional points for the number of times those words appear on the page. Feedback or links to articles on this would be appreciated. I'm leaning towards doing so on the SQL side myself but my SQL skills are not as polished as I would like for jumping into that, so examples could be good.
Hi - I'm short of SQL experience and hacking my way through creating a simple search feature for a personal project. I would be very grateful if anyone could help me out with writing a stored procedure. Problem: I have two tables with three columns indexed for full-text search. So far I have been able to successfully execute the following query returning matching row ids: dbo.Search_Articles @searchText varchar(150) AS SELECT ArticleID FROM articles WHERE CONTAINS(Description, @searchText) OR CONTAINS(Title, @searchText) UNION SELECT ArticleID FROM article_pages WHERE CONTAINS(Text, @searchText); RETURN This returns the ArticleID for any articles or article_pages records where there is a text match. I ultimately need the stored procedure to return all columns from the articles table for matches and not just the StoryID. Seems like maybe I should try using some kind of JOIN on the result of the UNION above and the articles table? But I have so far been unable to figure out how to do this as I can't seem to declare a name for the result table of the UNION above. Perhaps there is another more eloquent solution? Thanks! Peter
I'm sure there is a way of cracking this, but I can't think of a good solution. Right now I am not happy with the solutions I come up with, one of which takes 4 minutes to run on SQL Server The scenario: User is presented with search page where one or more search terms can be entered/selected. There are no required parameters. It can be any or all of the possibilities presented. Below is a model of the search parameters presented. The user will either select to show more options under Profile ABC, or go down to Profile STU or Profile XYZ to show more options, or even select all Profiles and then select from Type 1 and either a. or. b. or. c. or ALL of the above. I cannot predict what a user will make part of the search query so I have to have a stored procedure ready which can handle any or all of the parameters a user may select. Am I biting off more than I can chew (it seems so)? Or is there an elegant way of handling the unknown combination of search parameters that a user might throw into my sql query? I'm running this under ASP 1.0 and SQL Server 2000.
[check to show the options below] Profile ABC [check to shore more options] Type 1
A. Contains fields for entering another data string and selecting from drop-down boxes B. ditto C. ditto D. ditto [check to show more options] Type 2
A. Contains fields for entering another data string and selecting from drop-down boxes B. ditto C. ditto D. ditto [check to show more options] Type 3
A. Contains fields for entering another data string and selecting from drop-down boxes
B. ditto C. ditto D. ditto [check to select more options] Type 4
A. Contains fields for entering another data string and selecting from drop-down boxes B. ditto C. ditto D. ditto [check to show more options] Profile XYZ (as above) [check to select more options] Profile STU (as above)
HI. I have 3 tables 1- std with : stdID , programID. 2- Programs with :ProgramID , Cost 3 - Movements with : stdID , balance. the first table contain the stdID and ProgramID , some times the std hasn't programID that mean he hasn't programID. then we return null. if the std has programID there is to cases. the first one he have a movement on his balance then we get the biggest balance for the std. the second case he hasn't any moventen then we get his balance from Programs table by the ProgramID .
I need sql server function that return table like this stdID , Balance that means every std with his Balance. Regards.

hi how are you please help me in my problem which i can't make it. Now, i have a project in ASP.NET and SQL Server 2005. let's call the project an image gallery, in my project i have a table named "Category" in which all the categories are in this table. also while adding a new category a new table will be created automatically with the name of that category. now, what i want is that to build a query that reads the contents of the tables that the tables name are the names of the each record in the "Category" table. is that possible ? please if any one help can me in my problem.
I have 2 tables, say table1, and table2. There is a DocID (primary key) in table1. In table2, DocID is the foriegn key. There can be more than 1 DocID.
how do I join these two tables, such that I get all the otherID's for each DocID. ie., DocID OtherID 1 2 and 10 and 13 and 25 2 3
i am writing this query to display search results on a search page (with keyword search) and so, if I display the result in more than one row, then the user might think that there is more than document...whereas the case is that there is only one document with more than one other ID's.
is there any way I can do this? display...more than 1otherID in the same row for the same DociD? Currently, I am using a left outer join of table1 and table2.

I might have to redesign the tables for this, but I'll ask anyway. I have a table with the following fields:
Email - VarChar Seminar - Int PeckingOrder - Int.
As I add addresses to the table, each one has a Seminar, and then each Seminar has a Pecking Order Value. If an email address shows up for more than one seminar, it can have multiple records. IE:
for address, seminar, and pecking order would be sample entries into the table. Give or Take 1000 records in the table at any given time. What I want to pull out is:
Distinct Email Addresses For each Email Address - The Max(PeckingOrder) And the Seminar that's associated with Max(PeckingOrder)
For the sample data set above, I'd want to see these two records returned by the query:
email1 - 1523 - 424 email2 - 1524 - 235
I can't seem to get the Having / Where clause right to pull those two records properly. Anyone have any suggestions?
Thanks, --Daniel
Edited - Didn't realize the BB removed email addresses.
SELECT goto_last_name as 'Manager', advisor_name, advisor_ao_number as 'AO', COUNT (CASE advisor_termination_date WHEN '<Null>' THEN 1 END) as '#Advisors', SUM(Weekly_TOS_GDC) as 'TOS GDC' FROM weekly_condensed_tb WHERE advisor_platform_number = 1 AND report_date BETWEEN CAST(CONVERT(VARCHAR,'9/11/2007',112) AS DATETIME) -28 AND CAST(CONVERT(VARCHAR,'9/11/2007',112) AS DATETIME) GROUP BY goto_last_name,advisor_ao_number,advisor_name HAVING COUNT (CASE advisor_termination_date WHEN '<Null>' THEN 1 END) > 1
In the query above i select a range from the date - 28 days and do a sum on the TOS GDC column. What i am trying to do is have another query where the range will be - 56 and maybe - 86 so i get the SUMS for that as well. I need to display this in SQL Reporting Services and i can only have one DataSet returned otherwise i will not be able to bind it to one table.
How can i go about this so i return one set of data for 3 different date ranges.
I'm struggling with a syntax error in my sp. I'm hoping someone can give it a fresh look and straighten me out. Thanks. Background: 1. The innermost query (using the dynamic statements) will run fine on its own. 2. I can wrap that in another query (with the innermost as a DERIVEDTBL) and it will run fine UNLESS I apply the GROUP BY. Then I get syntax errors. 3. Also, the entire query runs fine as a view (with hard coded vals for column and value). 4. I don't know what kind of formatting this message will apply, so just know that I've checked my line truncations and they all include a trailing '+. Also, I know that Occured is misspelled. That is the correct object name. Not all our DB admins are lit majors.
I have a sql table with corpcode, EmpName, rate, reportdate and Amount fields. I need to write a query that can return corpcode, EmpName, rate and sum of Amount for January, Sum of Amount for Feburary, Sum of Amount for March, Sum of Amount for April, ..........., Sum of Amount for December, Total for All months, Average for all months.
I tried few option, it didn't work for me, Is it possible to do? Have some tried like this earlier?
Hi, I want to create a query with which I must compare the production demands with the production results. The production demands can be get by the join of two tables. The production results can be get from an aggregate of 4 tables. The connection of these two objects rely on two fields that exist in both two objects. In order to show all the production demands I must left join the two fields from the demands object to the two fields exist in the aggegate production object. In MsAccess the only way to do it is to create 2 queries one for the demands and one aggregate for the production and in a third query create two left joins from the demands query to the production query and get the right results. How can I do it with MSSQL Server with a query??
BLOG --POSTER_ID --POSTED_BY (a FK refer to USERID) --UPDATED_BY (a FK refer to USERID)
USER --USER_ID --NAME
I want to retrieve the info for all posts that posted and updated by different users, also the query returns both user names for every posted and updated action.
I can write two queries to do that
select B.POSTER_ID, U.NAME from Blog B inner join USER U ON B.POSTED_BY = U.USER_ID
select B.POSTER_ID, U.NAME from Blog B inner join USER U ON B.UPDATED_BY = U.USER_ID
Then write some code to combine the result for the posted and updated user name. But this is not efficient.
I am wondering how can I write one query to archeive that?

I have tried various combination of Joins, but unable to get the desired result as the tables have many-to-many relationships, therefore I get many duplicate rows in the result. UNION will not solve the problem, as that will add the additional rows for the third table. Although I can achieve this by writing few lines of code, but I have to create a SQL Query for getting this result. Kindly tell me the way for creating the required Query for this. Many Thanks for your help.
Now, i have a project in ASP.NET and SQL Server 2005. let's call the project an image gallery, in my project i have a table named "Category" in which all the categories are in this table. also while adding a new category a new table will be created automatically with the name of that category.

Table Name: Story Table Columns: user_id, date, name, yr_left, city_origin, country_origin, yr_arrival, city_arrival, state_arrival, address, city, state, zip, AorV (audio or video), filename, approved
I need to create two queries. One based on date in descending order, and one based on country_origin in alphabetical order. For both of these queries, the approved field has to = Y for yes, and when I return results I need it to return everything in the table EXCEPT for the name.
I'm a beginner at SQL queries so I was hoping someone could shed some light and help me??? Thanks a bunch!
ID, EntryDate and Comment are all easily returned from the [Journal] table. The problem I am having is with the Income and Expense fields. For the Income field, I want to SUM the Journal_Split.Amount fields where Journal_Splts.JEID = Journal.ID AND where Journal_Splits.Type = 1 (1 being the code for Income). The Expense field is just the same, except the Journal_Splits.Type will be equal to 2. When the query is done there should only be as many rows as there are in the [Journal] table, for the [Journal_Splits] table can contain up to 3 records for each [Journal] record. [Journal_Splits] just holds the individual amounts split out to different income/expense categories for a single transaction.
This to me has a lot of conditions that I can't even seem to build with access's query builder (yes I am using access for now.. will change over to sql at a later time).
Anyone have a good idea how to do this? Or have a better idea for structuring the database to make is easier to query? Right now I have it working, but instead of an Amount field, I have 1 Income and 1 Expense field, but since a transaction can only be either income or expense, one field will always be 0, which seems like a waste of space.
That may be a bit confusing so let me know if I can clarify. Much appreciated.
HelloI am using stored procedure with sql 2005 (with Visual studio 2005)I have two tables ..
