1st Attempt, Designing, Would Like Somebody To Review And Critique It
Jan 23, 2001
Hello
This is my 1st attempt at designing a database, and I have not finished
it completely, but I would like somebody to review and critique for me.
I really don't want to make any mistakes with this and I would appreciate any expertise out there to direct, recommend, suggest improvements and/or changes, PLEASE.
Thank you for considering this,,,if you provide me with your e-mail, I can send you a script.
take care,
~Iris~

Here is a trigger I wrote to check for duplicate taxid's in my producer table. Duplicate taxid's with an '' value are allowed. I'm green when it comes to trigger coding so would anyone care to review my code and reply if there's a more efficient way to implement the trigger or handle errors.
Thanks PLJ
create trigger dbo.tib_producer on dbo.producer for insert as
begin
declare
@numrows int,
@errno int,
@errmsg varchar(255)
select @numrows = @@rowcount
if @numrows = 0
return
/* Check for duplicate tax_id if inserted is not null */
if update(tax_id)
begin
if exists(select tax_id
from producer
where tax_id in (select tax_id
from inserted)
and tax_id <> ''
group by tax_id having count(*)>1)
begin
select @errno = 50002,
@errmsg = 'Tax ID already Exists'
goto error
end
end
return
/* Errors handling */
error:
raiserror @errno @errmsg
rollback transaction
end

Hi,
I would really appreciate any constructive criticism of my sql script (see end of message).
I have been working for a week to pull data from a database that has evolved over the years. It might have been designed to begin with, but it has had a lot of changes made on the fly, which makes pulling some data from it very hard.
One example is that they wanted Primary Service for a given client but this data was not stored in a base client table, but was instead on a table with multiple rows per client. To pick the row that referenced the correct Primary Service I had to:
1. Join the Client table with the view on client number and primary program number
2. From the records returned look at another column (proc_cde) in the view and pick the one that had a higher priority than the others. The precedence order of the proc_cdes was determined by a list my boss gave me. I used this forum to help me figure this part out.
Anyway … I finally got it done and it works … but just because it works doesn't mean it is well written. What I would like is if some of you could take a look at the sql and critique it for good and/or bad practices.
The design of the database is a given (and not my doing) so I am not looking for a critique of it.
An Example of what I am asking for would be:
I ended up using temp tables to collect some of the more complicated data so that I could write a very straightforward final query. Was this a good or bad thing and if bad why?
I really want to get good at sql and avoid developing any bad habits, so please critique my sql.
Also please ask me any questions that could help you evaluate the code.
Thanks,
Laurie

I need a report showing all Adult MI consuemrs receiving psych services by agency- like the
aggregate and detail of who gets them at where-bridgeways, sr srv... including our clinic.
i would need in the detail- primary clincian/provider, primary service (act,cm,opt), location of service,
date of auth, cons name/number, auth date range/# of units and number of claims in the last fiscal year and
primary psycchiatrist. if xxx asks for something similar, let me know as we might be duplicating.
i know that xxx is going to be asking for a report that is for just our clinic that has more to do with
insurance type. if it would be easier, you could combine the 2 reports as long as we have the capacity
to sort and print by provider. thanks*/

I just finished a new query where I summarized detail information. I'mwondering if I did this really awkwardly or is this a common way towrite SQL? I've cross referenced the end results and the data seemsconsistant, so I am happy with the results.TIASELECTSESSION_ID,CAMPUS_ID,SUM(STUDENT_COUNT) AS STUDENT_COUNT,SUM(NEW_STUDENT) AS NEW_STUDENT_COUNTFROM (SELECTSESSION_ID,STUDENT_ID,CAMPUS_ID ,STUDENT_COUNT ,STUDENT_STARTING_SESSION_ID,NEW_STUDENT = CASE WHEN SESSION_ID=STUDENT_STARTING_SESSION_IDTHEN (1) ELSE (0) ENDFROM (selectSESSION_ID,STUDENT_ID,CAMPUS_ID ,STUDENT_COUNT ,STUDENT_STARTING_SESSION_IDFROM(selectSESSION_ID,STUDENT_ID,CAMPUS_ID = (SELECT STUDENT_CAMPUS_ID FROMD_BI_STUDENT WHERE A.STUDENT_SKEY=D_BI_STUDENT.STUDENT_SKEY) ,STUDENT_COUNT = DAY0_CLASS_COUNT,(select student_starting_session_id fromf_bi_student_statistics where A.student_id =f_bi_student_statistics.student_id) as 'STUDENT_STARTING_SESSION_ID'from f_bi_registration_tracking_summary A) AS XWHERE STUDENT_COUNT > 0GROUP BY SESSION_ID, STUDENT_ID, CAMPUS_ID, STUDENT_COUNT,STUDENT_STARTING_SESSION_ID) AS Y) AS ZGROUP BY SESSION_ID, CAMPUS_ID

I was building out my db and then ran into a problem updating a primary key value. I then started to doubt whether or not I even did this right. To simplify, I"m going to just create a smaller similar scenario and I just want to know if its right
Lets say I have three tables
Order Tableordernum (PK)orderdateorderamt
Phone TablePhonenumber (PK)ordernum (FK)NumbertypeInternet TableCircuitID (PK)Phonenumber(PK)IPSMGW
now, Instead of creating a seperate column for just an incrementing numeric value as a PK i used the order number, phone number, and circuit id's as the Primary keys since every single value will be unique. Plus, I also did it to prevent duplicates. Now the problem I'm having is, when I do Update db set [phonenumber] = @phonenumber, ordernum = @ordernum, numbertype = @numbertype where phonenumber = @phonenumber as wrong as that looks.
It looks wrong to me.. problably why it doesn't work. How do you change the values of primary keys.. or should I have created a column called ID with incrementing numbers. How would I prevent duplicates then?

All:
This proably is an unsual request. I have developed a package that runs fine and does what it is supposed to do. I am jsut not sure if I have developed it in the most efficient way. I have several years of ETL experience but only about 6 months with SSIS. I know I can benefit a lot if I had my package reviewed by an expert.
I realize that I am asking for some time committment on your part and so would understand if I do not get any takers. But if you would like to review my package and offer suggestions on its improvement please let me know. We can work on the logistics of getting the package to you.
Thanks!

Thanks for looking at this for me. Here is the SQL Script as it stands so far.
UPDATE TableImportHistorySET ImportStopTime = CONVERT(numeric, GETDATE(), 108), Elapsetime = CONVERT(numeric,GETDATE(), 108) - CAST((SELECT TOP 1 ImportStartTime FROM TableImportHistory WHERE TableName = 'ARCHRG'ORDER BY DataImportID DESC) AS numeric), Successful = 1WHERE (DataImportID = (SELECT TOP 1 DataImportID AS LastID FROM TableImportHistory WHERE TableName = 'ARCHRG') ORDER BY DataImportID DESC))
The Elapetime update portion of this statement is where I'm getting stuck (if I take it out the statement works)
I get the error "ERROR converting Data type NVARCHAR to Numeric" I've changed the data type in the Table from numric to varchar, nvarchar, decemial nothing works and not sure what I should set the Starttime and StopTime datatypes in the table to (any suggestions please)
Elapsetime = CONVERT(numeric,GETDATE(), 108) - CAST((SELECT TOP 1 ImportStartTime FROM TableImportHistory WHERE TableName = 'ARCHRG'ORDER BY DataImportID DESC) AS numeric)
Are there better ways to do this statement?
Thank you in advance

Hi,
I posted last year when we were having problems with a new SQL box we had moved to here...
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=74650
...we coded round most of the issues and deadlocks and things seemed to improve for quite a while but we have recently run into performance problems again of late.
The CPUs on our SQL box often thrash away at 100% and our ColdFusion website has begun running painfully slow.
Our developers/hosts have suggested we might need to look for a 3rd party SQL guru who could look at the SQL box, do some tracing etc. and perhaps make some recomendations around optimising the DB architecture or changing the way we run certain queries. At the moment we have only gut instinct on which bits of the DB are likely to be being hit most hard.
Our website has grown from being very small to being really quite busy and it's possible we are running into shortcomings with the design of the DB that need to be tackled before we can expand further.
I'm not sure what the protocol is (I see there is a Jobs part of the site) but I wondered about the possibility of getting one of you guys in for a short while to review our server and database, for a fee of course. I'm not sure how long it would take to review that kind of data and get a feel for the usage?
We are based in the UK and whilst I guess it could be done remotely it might be easiest if the person was UK based too.
I'm as much interested in feedback about the idea (it might be not workable/a good idea for example) as I am to people offering their services.
If this post breaks any rules please let me know.
Cheers,
Tem

Don't know if this is the appropriate forum. I am looking for an experienced SS consultant to review our setup, hardware architecture, recovery plan, and to provide high-level advice moving forward. My company is a CRM hosted software provider with a dynamic, metadata-based product built in Visual Studio 2005. Currently we run on SS 2000, but plan to migrate to SS 2005 or 2008. We anticipate quite a bit of growth and want to make sure that we are on the right path. Let me know if you are interested or know someone who is.
If I should post this elsewhere, let me know.

First of all, this is my initial thread here on dbforums. I come from the land of Broadband Reports and would like to say, Hello fellow DB enthusiasts. :)
I'm not a novice to relational databases (Access MDBs), but new to implementing a db via SQL SERVER (2000 in this case) and using Access Data Projects.
My partial db schema is as follows:
participants
---DID (pk) char(1)
---LID (fk - schools) char(4)
---studentLast varchar(50)
---studentFirst varchar(25)
Sample Data would be
010191M001 | 5671 | SPARKS | JONATHAN
030495F283 | 5671 | DYLAN | CYNTHIA
=====================================
enrollhist (insert/update trigger for enrollactive)
---EID (pk - autonumber) bigint(8)
---EMID (fk - enrollmode) int(4)
---DID (fk - participants) char(10)
---LID (fk - schools) char(4)
---enrollactive bit(1)
Sample Data would be
38173 | 4 | 030495F283 | 9003 | 0
38266 | 3 | 010191M001 | 5671 | 0
39022 | 6 | 030495F283 | 9003 | 0
39036 | 5 | 030495F283 | 9003 | 0
39044 | 4 | 030495F283 | 5671 | 1
39117 | 4 | 010191M001 | 5671 | 1
=====================================
enrollmode
---EMID (pk) int(4)
---mode varchar(25)
Sample Data would be
1 | RECEIVED
2 | WAITING
3 | PENDING
4 | ENROLLED
5 | DROPPED
6 | TRANSFERRED
10 | ORPHANED
11 | DENIED
=====================================
schools
---LID (pk) varchar(4)
---CTID (fk - caltracks) char(1)
---AID (fk - agencies) char(1)
---SDID (fk - schooldist) char(1)
---COID (fk - countydist) char(1)
---sitename varchar(25)
---sitetitle varchar(75)
Sample Data would be
5671 | 3 | 2 | 1 | 4 | ASCOT | ASCOT AVENUE
9003 | 2 | 1 | 4 | 1 | ROWAN | ROWAN AVENUE
2865 | 1 | 3 | 2 | 3 | BRIGHT | BIRDELEE BRIGHT
=====================================
caltracks
---CTID (pk) char(1)
---legend char(4)
---trktitle varchar(15)
---trkcnt int(4)
Sample Data would be
1 | 9030 | 90/30 | 4
2 | CON6 | CONCEPT-6 | 3
3 | SNGL | SINGLE TRACK | 1
=====================================
agencies
---AID (pk) char(1)
---legend varchar(4)
---agencytitle varvhar(50)
Sample Data would be
1 | CRYS | CRYSTAL STAIRS
2 | MAOF | MEXICAN AMERICAN FOUNDATION
3 | PATH | PATHWAYS
4 | CCRC | CHILD CARE RESOURCE CENTER
5 | CHSC | CHILDREN'S HOME SOCIETY OF CALIFORNIA
==========================================
THE REMAINING "FKs" FROM SCHOOL ARE SIMILAR, as is other tables and their relationships. The design of the foreign keys were made using sql and the keyword "REFERENCES" and "FOREIGN KEY."
My questions are: :confused:
(1) Is the use of FK as a Constraint any different than using an INDEX and how?
(2) Should I Alter the Tables to include CASCADING Up/Down?
(3) Are the use of CHARs Ok for the Keys?
(4) Have I over/under-normalized any of the relationships?

Hello,
I've proposed to the head of IT at my organisation to head an database development export group to:
- Provide assistance in improving the performance of existing relational databases
- Provide assistance for the development of new database, e.g. correct construction of indexes; data contention, etc.
- Creation of database development standards
- Enforce the above standards for new databases so that the database is not deployed to production servers until it passes the standards.
I'd really like this to be a success as it should improve our rather crappy databases, basically because the people currently creating the databases don't know much about relational design.
Can anyone please post their experiences of setting something like this up, or working on such an expert group where they work? I'd really like to hear the good and bad experiences and what and (what not) to avoid.
Thanks

I have an automation project to review the software. The software is using MSVS2012 and uses DBs from MSSQL2012. Is it possible to restore the DB files on my local laptop to review the code completed thus far? If so what other software would I need besides MSQLserver 2012 on my local laptop. I'm able to use MSSQL server 2012 on my local laptop, but the DBs are on servers.

Here is a script I wrote that analyzes datasets and returns all the minimal composite and unary keys that uniquely identify records. I wrote it because I frequently have to analyze client spreadsheets and non-normalized data tables.
On my desktop server it took about two minutes to analyze 2000 permutations of a table with 50 columns and 5000 records.
Please try it out for me and let me know if it chokes on anything, or if you see any ways it could be improved!

Hi,
I'm having 2 issues on my first "real" SSRS report.
1. How to do a print preview via the preview tab. For print rendering, I have no print preview button on the preview toolbar. Is this normal? MS documention said that there is a Print Preview button. (BOL May 2007 - Designing & Creating reports -> working with report designer -> debugging and Publishing reports (Print Preview)) This report will always be rendered via the printer and it is a "pain" to have to always print it to see changes. The print layout option comes up all black with nothing viewable.
2. How do I reset page numbers back to 1 for report groups? I see no option for this. My report group requires a new page and I want page numbering to start at 1 when the grouping changes.
Note: I'm running VS2005 via Vista (with VS2005 Vista fix installed). SQL2005 SP2 also installed.
Any advice on this will be appreciated. I've spent too much time already where this should be obvious.

Not seeing the Review Data Type Mapping Screen in SQL Server Import and Export Wizard?
Is there only a certain version where that screen shows up?
I am trying to import data from an MS Access application to SQL Server and all of the connections are good, but some of the data isn't and if I let it migrate using this tool it crashes on the bad data and there is no data that migrates. The Review Data Type Mapping screen will allow me to bypass the records in error and load the rest. however, I can;t do that if I cannot see the screen.

I am new to sql server. Currently i am using sql server 2000. i have created two tables course and student , with course_id and stu_id , as primary key of the respective tables.
Now i am trying to relate them through the diagram , in order to create a relationship between the two. When i try to draw a relationship between stu_id and course_id , i get the following error
error: Unable to create relationship 'FK_stud_course'.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'FK_stud_course'. The conflict occurred in database 'student', table 'course', column 'course_id'.

Im creating a sample database for purposes of keeping track of employee's jobs + billing codes for that job. currently they just use an excel spreadsheet to keep track of billing.
Question 1:
What would be the easiest way for the manager to enter billing codes? Billing codes are numbers like 956, 958, 805 and they co-relate to prices for each billing code.
1. I want the manager to enter the billing code and have the sql database find out how much that code is and add them up daily. This would prevent the manager from having to input prices and billing codes, and extra step.
Any links on the above topic would be helpful. I'm not looking for anyone to spoon feed me code just point me in the right direction. Im relatively new to sql having only a class of sql @ ITT.
Heres the way I have the db tables laid out currently.
employee table
employee_id
technumber
fname
lname
address
workphone
homephone
trucknumber
officelocation
employeejobs table
employee_id
jobs_id
jobs table
jobs_id
codes
date
timeframe
city
hours table
hours_id
employee_id
hoursworked
month
Any info would be much appreciated, Im going to go find a sql book now ;).

Hi, not sure if this is the right forum for this question.
I am creating relational tables for the first time in sql server express. I will have an orderItems table and an orders table. the MenuItems table is the problem. It is a catalogue of books. There will be about ten columns. all are unique to each book. i.e isbn number, title, author, publisher etc. but ten columns seems to be quite cumbersome. it may be easier to break the table down into two tables (i.e. primary details and secondary details perhaps) However to populate the table in the first place it would be easier to have it as one table instead of opening and closing 2 tables Adding the odd book to the two tables in the future would not be a problem. so the question is can i create a table and then brak it into two relational tables afterwards. If so how do i do this. this is my foirst go at relational tables and i am still trying to get a handle on visualising them. If my logic is up the wall please let me know....

Hey,I have a fairly large table for my keeping my information about users. My question is, would it be better to separate it, for example, create another table that has all the personal information (like city, street, etc)and have it related to my other table where more of the data-ish information is kept? Thanks,Sixten

2. Table columns
3. Table rows

Can any one give full Idea on this question?
Thanking you Ashok kumar.
