Queries

Apr 24, 2008

how do i make a querie that finds relations to a "part number" for models, and assemblies, but when it finds a relation of part number with a Product, it gives additional attributes for information?
this code that i have so far doesn't do waht i want,, showing

part_number
2 2 1 1 Kilimanjaro
2 2 2 2 Dolomiti
2 2 11 11 Mud Zinger 1

and jumbling up information

select part_inventory.part_number, assemble.assemble_number, model.model_number, product.serial_number, model.model_name
from part_inventory inner join model_configuration on part_inventory.part_number = model_configuration.part_number
inner join model on model.model_number = model_configuration.model_number
inner join assembly_configuration on part_inventory.part_number = assembly_configuration.part_number
inner join assemble on assemble.assemble_number = assembly_configuration.assembly_number
inner join product on product.serial_number = model.serial_number
where part_inventory.part_number = 2;

Parameterized Queries Running Slower Than Non-parameterized Queries

Jul 20, 2005

HelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)

Is It Possible To Put Several Queries Into One Sp

Dec 7, 2007

 I have an update query which either inserts a row or increases quantity, depending if row exists or not. It works, better than my explanation probably.After that query could be a good time to count total of all calculated sub sums.Something like this.  previous queryEND goSELECT SUM(SubTotal)FROM dbo.t_Shoppings I have tried this on the tool which has a long name, but I think my way didn't work. (Microsoft sql server management studio express)Is this possible or do I have make and call another stored procedure.I can send my sp if someone wants.

Queries In SQL

Aug 3, 2000

I just upsized my Access2K db to SQL. I am using Front Page 2000 for my website. When I had the database as Access, I was able to use one of my Access queries as my record source for my data base. I was able to choose between my queries AND my tables as the source for my records. Now that I've upsized, I am no longer given that choice. My only choices are the tables. Unfortunately, my database is designed to pull records from a query, not just a table. So my question is, in FP2000, how do I use a QUERY from my newly upsized SQL db as my record source?

Thank you all very much in advance.

Two Queries Necessary?

Oct 12, 2007

Hi and thanks for reading.

I have a query that requires multiple joins and has several one-to-many relationships with other tables. The basic query I have is this:

Code:


SELECT TOP 50 eventID,eventTitle,eventAbstract,eventInsertDate,eventUpdateDate,eventAuthID_fk,
eo.eventOccurrenceID,eo.eoDescription,eo.eoApprovedDate,
l.LocationID,l.LocationShortName,c.categoryID,c.categoryName,a.ageID,a.ageDescription
FROM enm_eventOccurrence eo INNER JOIN enm_events e ON e.eventID=eo.eoEventID_fk
LEFT JOIN (enm_categories_occurrence co LEFT JOIN enm_categories c ON c.categoryID=co.co_categoryID_fk) ON eo.eventOccurrenceID=co.co_eventOccurrenceID_fk
LEFT JOIN (enm_location_occurrence lo LEFT JOIN location l ON lo.lo_locationID_fk=l.LocationID) ON lo.lo_eventOccurrenceID_fk=eo.eventOccurrenceID
LEFT JOIN (enm_ages_occurrence ao LEFT JOIN enm_ages a ON ao.ao_ageID_fk=a.ageID) ON ao.ao_eventOccurrenceID_fk=eo.eventOccurrenceID



This works, but it will pull out multiple rows for the same eventOccurrenceID (the PK for eventOccurrence) because of the several one-to-many relationships. For instance, there could be multiple categories, locations and ages for one event occurrence, so this will produce multiple rows.
But, since I need to get only a limited of rows, the TOP will fail since there are multiple rows for each, and there's no way to tell how many rows exactly will come out (so just multiplying the TOP value is out of the question).
Using DISTINCT or GROUP BY also seems to be out of the question, since I need to have the fields from the one-to-many tables in the SELECT list but cannot GROUP BY them.

My proposed solution is to run a query selecting only the eventOccurrenceID and using the WHERE information that the user is requesting, then running another query (with the full select list) with a "WHERE eventOccurrenceID IN (".
But, I hate using two queries and just wonder if there's a better way around this.

Appreciate the help, and thanks for reading.

What To Use For SQL Queries?

Feb 15, 2007

I frequently need to run ad hoc queries against a database, capturing the output in a text file. In SQL Server 2000 I used Query Analyzer with no problems. In 2005 I'm trying to use the query function in Management Studio-but the output is (so far) unusable due to a Null character (hex 00) that follows every 'real' character. I assume this is due to Unicode but haven't found any way (yet) to tell it to just output in plain everyday text. (ASCII or ANSI-either will work.)

Is there some other tool I can use for SQL queries?

Thanks.

Sql Queries

Jul 2, 2007

It is given the following schema of relations:

Donators(Id <<PK>>, Name, Surname, IdCity <<FK(City)>>, Group, Sex, Age);
Files(IdFile <<PK>>, Donator <<FK(Donators)>>, Date, Type);
City(IdCity <<PK>>, Name, State);

I need to find a query for each of the following:

1. name, surname of the plasma donators(type='plasma'), with Sex='F' and younger than 45 years old.

My solution:
SELECT d.Name, d.Surname
FROM Donators d, Filles f
WHERE d.Id=d.IdFile AND f.type='plasma' AND d.sex='F' AND d.age<45

2. average age of the plasma donators

SELECT AVG(d.age)
FROM Donators d, Files f
WHERE f.type='plasma'

3. the states which have more donators

I have no idea how to do it

4. the id's of the plasma donators from Chicago

SELECT d.id
FROM Donators d, Files f, City c
WHERE d.id=f.idfile AND d.idcity=c.idcity AND f.type='plasma' AND c.name='Chicago'

5. the id's of the cities without plasma donators

SELECT c.idcity
FROM City c
WHERE NOT IN (SELECT c.idcity
FROM City c, Donators d, Files f
WHERE f.idfile=d.id AND f.type='plasma' AND d.idcity=c.idcity)

6. remove the donators older than 80, after having removed the corresponding files

No idea how to do it

In conclusion, could you tell me if my queries are correct and help me with the others?

Thanks

SUM Of Two Sub-queries

Jun 26, 2012

Table 'dbo.tblonenet_sdt_proj_hold' Schema as follows:

cust_id int
dateon DATETIME
dateoff DATETIME

There are two possibilites

1) Its no longer on hold and so a dateon and dateoff value will be in the table.

2) Its still on hold and so dateoff will be NULL.

I want to add the total time its been on hold between the two dates and there could be multiple entires for cust_id 802

SELECT Hon,Hoff FROM

(SELECT sum(dbo.GetBusinessdays(dbo.tblonenet_sdt_proj_hol d.dateon,getdate()))
FROM dbo.tblonenet_sdt_proj_hold
WHERE cust_id='802' AND dateoff IS NULL) AS HON

[code]...

The resulting error in SQL Management Studio 2005 is 'No column was specified for column 1 of 'HON'.'

Queries???

Mar 18, 2004

I'm confused.

I am creating a interaction application for alton towers available through a website (using asp.net). This website is connected to a database(sql server 2000) containing infomation on different shops, rides, restaurants and facilities at the park.

I have inputted data to my database. The user should be able to do searches such as:
rides (and shops or all) available in a certain area.
rides in a certain area above a certain height rescrictions.
etc

I'm confused. I have used SQL statements before and I know it is possible to retrieve this information from the database, but how should I go about this and how should I be storing this information so that I am able to call it from the front teir.

I have read up on views, stored procedures and triggers and I'm a bit lost. Should I be creating all the possible queries and then store them as a view (or stored procedure) I thought I would just have to write a sql statement but it seems a lot more confusing...

and what about triggers and user defined statements??

PLEASE help, I have a deadline in a week : (

THANK YOU

This gives me
Invalid object name 'R'.

outside the CASE statement ?

I have tried putting the inner SQL in the CASE
