I have a table called acc1152 with the field accno. depending on what the value of this field is, i need to replace it with a new value. These are the values i need to update
old value new value

how do I write one query that will accomplish this?
Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables. I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key. Is there a way to automatically create new records in the foreign tables that will have the new id? Would this be a job for a trigger, stored procedure? I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.

Table2 contains fields Group, Name,Category, Dimension (Group and Name are not in Table1)
So basically I need to read the records in Table1 using Groupid and each time there is a Groupid then select records from Table2 where Table2.Category in (Select Catergory from Table1)
and Table2.Dimension in (Select Dimension from Table1)
In Table1 There might be 10 Groupid records all of which are different.
I am trying to write a query that will retrieve all students of a particular class and also any rows in HomeworkLogLine if they exist (but return null if there is no row). I thought this should be a relatively simple LEFT join but I've tried every possible combination of joins but it's not working.
SELECT
Student.StudentSurname + ', ' + Student.StudentForename AS Fullname,
HomeworkLogLine.HomeworkLogLineTimestamp,
HomeworkLog.HomeworkLogDescription,
ROW_NUMBER() OVER (PARTITION BY HomeworkLogLine.HomeworkLogLineStudentID ORDER BY
[Code] ...
It's only returning two rows (the students where they have a row in the HomeworkLogLine table).
Hello,
I'm hoping someone can point me in the right path with a design issue I'm running into. I'm somewhat new with database design and SQL server, so bear with me.
I'm creating a sort of project management system, and I've got a main PROJECT table, and then a STUDENT_PROJECT_PARTICIPANT table, with foreign keys to STUDENT and PROJECT tables. Each has an 'institute' field. What I want to do is to be able to report on the number of students involved in each project, the number of unique students involved in project with a particular institute, and then the number of unique students involved in all projects. I'd also like to be able to report the number of unique students involved in a custom-picked list of projects (this seems the least feasible). The trick is that I need to report this statics within a specific date range. My original idea was to just save statistics of the numbers of students involved in a project every time it is saved, but from there I'm not sure how I can find out the unique count for all projects, since I don't have the date that each student was saved. That's my basic problem. Let me know if you need any clarification.
If anyone has done something similar or has any advice for me on this, please let me know!
Thanks!

I would like to create a table called product. My objective is to get list of packages available for each product in data grid view column while selecting each product. Each product may have different packages type (eg:- Nos, CTN, OTR etc). Some product may have two packages and some for 3 packages etc. Quantity in each packages also may be differ ( for eg:- for some CTN may contain 12 nos or in other case 8 nos etc). Prices for each packages also will be different that also need to show. How to design the table..
Product name :
Nestle milk |
Rainbow milk
packages :
CTN,OTR, NOs |
CTN, NOs
Price:
50,20,5 |
40,6
(Remarks for your reference):CTN=10nos, OTR=4 nos
| CTN=8 Nos
I can't get my head around this:I want to select all IDs from table A that do not have a related record intable B according to some condition:Table A contains, say, Parents and table B contains Children. I want toselect all Parents that have no children called "Sally" (this is a noddyexample, reminds me of being at Uni again :) ).Any ideas?Thanks
View 2 Replies View RelatedI have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..
I have a table with about half a million records, each representing a patient in my county.
Each record has a field (RRank) which basically sorts the patients as to how "unwell" they are according to a previously-applied algorithm. The most unwell patient has an RRank of 1, the next-most unwell has RRank=2 etc.
I have just deleted several hundred records (which relate to patients now deceased) from the table, thereby leaving gaps in the RRank sequence. I want to renumber the remaining recs to get rid of the gaps.
I can see what I want to accomplish by using ROW_NUMBER, thus:
SELECT ROW_NUMBER() Over (ORDER BY RRank) as RecNumber, RRank
FROM RPL
ORDER BY RRank
I see the numbers in the RecNumber column falling behind the RRank as I scan down the results
My question is: How to convert this into an UPDATE statement? I had hoped that I could do something like:
UPDATE RISC_PatientList_TEMP
SET RRank = ROW_NUMBER() Over (ORDER BY RRank);
but the system informs that window functions will only work on SELECT (which UPDATE isn't) or ORDER BY (which I can't legally add).
We need to Insert/Update a Fact Table from staging Table. currently we are using a SP which update Fact Table for Each region. this process is schedule, every 5 min job is run and Update fact table.but time of Insert and Update too long from staging to Fact, currently we are using merge statement for Insert and update.in my sp we are looping number how many region we need to update and at a time single Region we are updating using while loop in current SP.

I have think three ways to do it.
1. leave as it is.
2. 7 years partition on one server
3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)

Coming from a support background and having to design my first database I have a couple of questions re- table design. Firstly I have set up several tables and included one field (of the same name) in each. This is a primary key in one table with an incremental seed. I would like this info to appear in the other tables although these can be duplicates in the other tables. How is it best to achieve this relationship. From reading it suggest FK in the relationship application but looking at other databases this seems to have been achieved by some other means. Is it more common to use stored procedures to enforce this? If so please add pointers. Secondly, I have set up a couple of master tables to act as looks ups for fields in other tables. Again how do I get this to look up the table - is it done through stored procedures or at the time of writing the front end application?? Sorry if this is all basic stuff but it is new to me.
Thanks for any help

I have created a table with above column width. The rowsize is more than 8kb.And the table holds millions of rows of data. So is it a correct way of designing the table?
Or how can I redesign this table.

I'm currently developing a real estate system to manage order processing and work flow. I'm a little uncertain as to how to design the tables because an order can have N number of applicants, owners, buyers, and properties. There are cases where there are 9 different buyers and some where the number of properties exceeds 20. It seems that normalization might make the situation crazy, but I'm a touch rusty. Thanks.
View 2 Replies View RelatedI am developing an estimating application and at the "quantity takeoff" level, all products/equipment/sub contracting/etc.... end up on the same table because of the common elements:
Item | Quantity | Unit Price | SubTotal | Total

Hi am trying to figure out my table design need some advice
I have a table that catches the telephone numbers of a customer , there are 5 telephones for each customer. All the numbers are there in the DB
Should I create the design in the following format
CustomerName
Tel1
Tel2
Tel3
Tel4
Tel5
Or Should I have
Customer
Telephone
& then have 5 rows for each customer
Please advice
I even wanted to knw how should the design be , if all the Tel Nos are not captured, I mean what if some customers have 3 tel Nos, while some may just have 1 while some may have all 5
Thanks

In employee table I have to store two country names.
ie. employee currently working in this country
but his home country name (origin country) is another
name. In country table all countries information available.
ie. country_code and country_name.
How I can design the employee table that it get country_name from COUNTRY TABLE ?
but we can not use same country_code in two fields.
OR
otherwise I will have to create employee table like this
employee table
------------------------
EMP_ID varchar
NAME varchar
DEPARTMENT_CODEint
POSITION_CODEint
COUNTRY_CODEint
COUNTRY_NAMEvarchar
ie. during data entries direct insert the country_name in employee
table ?
I want to create separate table for separate data.
department,postion,country.
How I can use unique country_code in employee table's two
fields ?

Hi,
I'm struggling coming up with an optimal table design for the following scenario.
I have a table in which each row is recording information about a document - author, publisher, publication, title, abstract and so forth. I also have an image table which contains information about the images which can be associated with the documents.
Each document can have on of three image types associated with it - an author photo, a publisher logo and a publication logo. There aren't actually that many different authors, publishers and publications in the database so it would be common for many documents to have the same author or the same publisher although authors sometimes write for different publications. In the current setup it's possible for a document to have more than one image of each type associated with it, which is undesirable - this needs to eliminated and we need to ensure that each document can only have one image of each type associated with it.
It'd also be a huge boon if I could get all the information about a document and it's attached images with a single database call. In the current setup, trying to do this returns multiple rows so I've ended up making two calls, one for the document and one for it's attached images.
I can see two possible ways of setting this up, neither of which appeal.
The first is to add three columns to my document table to record the image URLs which is simple but inflexible should I want to add more image types later on.
The second is to set up three new tables for author, publisher and publication and associate each of these with the document table through a key and then to the image table through another key. There's also an image type table which is going to come in to play. I'm unwilling to do this because it's going to just explode the number of tables I've got, especially if we add more image types, and play havoc with my XML schemas.
Is there another way of rationalizing this that I've missed?
Cheers,
Matt
Hi,
I am trying to decide between 2 table designs. I basically have several different types of work items that need to be tracked. Each work item has their own set of statuses, some of which may be the same as other work item's statuses, some of which will be unique for that work item.
Now, should I create one status table for each work item, or would it be better to use one status table, but add a column to track which work item the status belongs to?
I'm not sure which is a better design, or perhaps there is some alternate design that is better. Any help is appreciated.
Thx.
Currently I need to design database table and got stuck.
I have a project and its sub projects. A parent project and its sub projects share the same requirement.The description of the requirement will be changed every day.
For example
Project A - Do Some thing 1 on Project A [09/28/2007]
Project A-A1 - Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007]
Every time the comments updated, both project A and project A-A1 should share the same update i.e select project A and its subproject will be displayed
Project A Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007]
Project A-A1 Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29//2007]
When you tried to insert new sub project, the requirement will be shared with the parent project ie.
Project A - Do Some thing 1 on Project A [09/28/2007]
Project A-A1 - Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007]
Project A-A2 - Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007] , Do Some thing 2 on Project A-A2 [09/30/2007]
assume Project A-A1 and Project A-A2 are sub project of project A
Could anyone show me how to design the database table for those mess?
Thank you
Hi All,
If I have the following data that I need to put in a lookup table, what would be considered the proper create table schema for it?
G, "Group"
R, "Region"
D, "District"
Would you setup your table like this:
Level_ID Varchar(1),
Level_Desc Varchar(20)
Or would you go ahead and create like this
Level_ID Integer,
Level_Code Varchar(1),
Level_Desc Varchar(20)
Not sure which one would be the preferred method.
Thanks,
JJ
I have a huge database and off lately, I have been experiencing some performance issues on some queries. Some of my tables now have over 10 million records. I noticed the performance issue was caused mainly from one table created as a work around. If I remove the column from the workaround table (but still leave the table in the query), I get the results in 1 second. However if I include a column from the workaround table, the same query takes 14 seconds (same output only an extra column) . I will appreciate any advise on a better design to get around my workaround table.
Below is my scenario
Table - Team
-------------------
Column -
TeamID (Primary Key)
TeamName
Table - Matches
---------------------------
Columns -
MatchID (Primary Key)
MatchName
Team1ID (Foreign to "TeamID" in Table "Team")
Team2ID (Foreign to "TeamID" in Table "Team")
Table - Players
----------------------
Columns -
PlayerID (Primary)
TeamID (Foreign to "TeamID" in Table "Team")
PlayerName
The above tables work very well... The tables I listed below are my cause of issue... I need to write a query to list every match with the names of players who played in it comma delimited (one row per match).
I created a table
Table - MatchPlayer
-----------------------------
Columns -
MatchPlayerID (Primary)
MatchID (Foreign to "MatchD" in Table "Match")
PlayerID (Foreign to "PlayerD" in Table "Player")
But I couldnt write a query that would list me all the players comma delimited in one row per match..
So I put a workaround
Table - MatchPlayer1
-----------------------------
Columns -
MatchPlayerID (Primary)
MatchID (Foreign to "MatchD" in Table "Match")
Team1PlayerNames (Comma Delimited values - varchar(800))
Team2PlayerNames (Comma Delimited values - varchar(800))
This allows me to easily list the player names comma delimited per match but is a very bad design. Is it possible to list the same using the table Match Player.
Thanks in advance
hi there,im new to sql server 2005 and this forum
need help here pertaining to the database table definitions
all was well when i started using it a month or 2 ago until now that when i tried to redesign my tables,it wouldnt prompt me to choose a primary key for my table
previously what happened was that when i saved the table without selecting an attribute as a primary key,it would prompt me to do so nu could choose to have the primary key auto-generated
but now it seems it stopped prompting me about it
whats wrong with it?anyone else faced this?
pardon my question,im a noob at this sql server thingie
thanx in advance!
We are in the early stages of developing a small project and I have a question I would like an opinion on.
When deciding how to design a table to store information on users who will be different types.
The project involves setting up webpage that allow " appointment setters" to book demos for our Sales reps. We want to keep track of how many each appointment setter books.
I have a user table with user_id, fname,lname, type. Where type represents the type of users they will be either "appointment setter" or "Sales Rep".
In the Appointment table I would like to store the Appoinment setter ID, sales rep Id, date/time appointment was booked and some other data on the appointment.
My question is how do I set up the relationship from the appointment table back to the user table.
Since each record in the appointment table will have a App Setter ID and a Sales Rep ID.
Should I just pick either the app setter id or the sales rep id as the foreign key back to the userID in the user table. Or is there another method how to handle this.
Any thoughts or articles would be greatly appreciated.
thanks,
hi,
i have a table with data in the following format (dont ask why it was done this way, its not something i can change)
so my table looks like this:

var1 11:00 5
var2 11:00 2.3
var3 11:00 21
var1 12:00 5.2
var2 12:00 2.4
var3 12:00 18
and so on.
i would like to have my data rearranged to look like the following:
timestamp :var1 value :var2 value :var3 value
________________________________________________
11:00 x y z
12:00 a b c

i am working with my database in a c sharp application. so if anyone does come up with a solution for this maybe keep that in mind so that i can discuss how to impliment it in the code.
thanks guys.
i am putting together an application for a client of mine that involves image heavy data handling. i have a couple of possible methods in mind of how to go about this, and would like some outside opinions, especially from any of you who may have done anything similar before.
to quickly sum up the application's desired results: a photo gallery that contains four sections of job before/after photos. 1)residential 2)comercial 3) automotive and 4)specialty. when a site browser clicks a section, it will bring up a gridview of the "key" or ideal photo (one each)from several different jobs. the site browser can then click the photo, and a new page (or new control, does'nt make much difference) will come up showing all photos for that particular job.) past and current customers will create user logins to have ability to upload photos of their specific job. admin needs ability to 1)upload photos for many jobs 2)review all photos before posting them to the gallery 3) would like to give admin ability to order the photos within the gallery and within each job 4)admin needs ability to create tagline with short description either for each photo or at least for each job.
as to the design of the data, i can either store the images themselves in the database, or create tables to tag the images with various identifying data, then simple store and call the images in a directory on the server. i have code to do either. i am trying to construct a database design to handle all issues. i like the idea of storing photos in the database more, just not sure how to architect it. it would be the 4 albums, each with infinitely create-able 'job' albums within, each job album housing job photos.
i am thinking the images maybe get a table for their specific info (ID as primary key, image itself, file type, length, and a foriegn key to a job table that has jobID primary key) the job table could have a job name that user inputs, thus identifying all photos to the same job. the job table would also foriegn key to the album table id, with its four categories of residential, automotive, commercial, and specialty. does this method seem feasible? if this system seems workable, i can throw in a boolean default to false for the admin to set true to display the job photos as a whole, with admin power to delete photos on an individual basis. but i am a little stumped how he can maybe order them? maybe an int field that he can edit and just manually put the jobs in the order he wants? and then put the photos under the jobs in the order he wants as well?
it seems i have somewhat thought this out just now while writing, so it seems i have a somewhat workable solution, if awkward, but if anybody knows a simpler, or tried and true, method, please let me know
any ideas, suggestions, and help is greatly appreciated.
