Thanks for replying to the question. We were able to resolve it by changing the SQL insert statement used to write(insert) the record. We removed the GetDate() function and used a string variable to hold the date read. Then we passed it into a datetime type variable in the SQL statement. Without changing the update SQL statement, we were able to update the record.

I have an existing SQL production database. During new developments, new fields/tables/stored procs etc have been added.
Now I want to merge these changes into the production server (without loosing data).
I could write a program to do it, but is there an easy way?

We use SQL Compare[^].
The alternative is of course to save a script every time you make a modification, or simply to make the changes using a script in the first place, but that's not really an option for you now.
The only other free alternative - the way we used to do it - is to export the database schema to a file using the Generate Script feature from both the old database and the new, and use a diff tool (such as WinDiff) to compare them. This will at least show what's changed. Then you write another script which uses ALTER DATABASE/ALTER TABLE/etc as appropriate to make the necessary changes.

hey guys,
How can i get the values oif multiple columns in rules? I was Googling up rules and all i could find was the method to use single column. Let me give you an example:
In an table i have many columns, three of which are X,Y & Z. I want to create a rule that checks if the sum of three columns are greater than 1000. If i do manage creating a rule and bind it to column X - how do i access the value of Y and Z from my Rule. Could some give explain. A peice of code would be really helpful.
Thanks.

It will show the same output unless the database changed between runs.
DataReader provides a forward only view of the data. The DataSet is a container that is used by a Data Adapter so that the result set can be accessed in a random access within the application.

Hi,
I want to run Job using any command prompt utility. Such type of utility is there in SQL Server 2000?
I know about DTSRun.exe is used to run DTS package, but I want to run Job as a whole.
Thanks.

How to reset a database's identity value to 0, after deleting all rows from a table.
FIRE
|
|
|
|

I don't know the exact way but one workaround is there. You change that column identity to no and again reset it to yes, next time it will start from one.

I not sure is there way to show percentage of my sales.
I have done a SQL on showing the total sales and now i want to calculate the percentage of total for each department. Example
TOTAL sales= $100
Vendor1 =$20
Vendor2 =$10
........
how can correctly show another column that will calculate the percentage?? I have try many method but not working... i was thinking to write as
sum(ti.totalsales)/sum(sum(it.totalsales))*100 as precentage
is SQL able to support those complicated calculation? or i have to do it in vb...
---HEre is the basic show the total sales with out percentage...
select d.deptdesc,v.[name],ti.deptcode ,sum(ti.totalsales) as Total from
tot_item ti , dept d, item i, vendor v
where ti.itemcode=i.itemcode and v.vendorid=i.vendorid and
ti.deptcode=d.deptcode
group by v.[name], ti.deptcode, d.deptdesc
ORDER BY v.[name], ti.deptcode ASC
|

The sample query you list has both Department and Vendor in it (you could get departments listed more than once if they use different vendors). You are trying to get a percentage of total for each department but your sample result set lists no percentages and values are listed by vendor. Are you sure you know what you really need?
Given your 2nd line and assuming you are using SQL Server, first calculate a good total sales per department.
SELECT
d.deptdesc,
SUM(ti.totalsales) AS DeptTotal
FROM
tot_item ti
INNER JOIN
dept d
ON (ti.deptcode=d.deptcode)
Now write a query that calculates total sales.
SELECT
SUM(ti.totalsales) AS FullTotal
FROM
tot_item ti
Now put them together
SELECT
dep.deptdesc,
(dep.DeptTotal /
(SELECT
SUM(ti.totalsales)
FROM
tot_item ti)) * 100 AS PercentOfSales
FROM
(SELECT
d.deptdesc,
SUM(ti.totalsales) AS DeptTotal
FROM
tot_item ti
INNER JOIN
dept d
ON (ti.deptcode=d.deptcode)) AS dep
ORDER BY
deptdesc
Note: I am using a more modern form of the JOIN syntax. There are issues with expressing the JOIN in the WHERE clause. You can make this a lot cleaner using variables in a stored proc.
|
|
|
|

Sorry - forgot the GROUP BY clause in the aggregate:
SELECT
d.deptdesc,
SUM(ti.totalsales) AS DeptTotal
FROM
tot_item ti
INNER JOIN
dept d
ON (ti.deptcode=d.deptcode)
GROUP BY
deptdesc
This will also need to be modified in the final query.
|
|

|

You can try something like this:
DECLARE @TempTotal int
SELECT @TempTotal=sum(ti.totalsales) from ti
select d.deptdesc,v.[name],ti.deptcode ,(sum(ti.totalsales)/@TempTotal) as Total
from
tot_item ti,
dept d,
item i,
vendor v
where
ti.itemcode=i.itemcode and
v.vendorid=i.vendorid and
ti.deptcode=d.deptcode
group by v.[name], ti.deptcode, d.deptdesc
ORDER BY v.[name], ti.deptcode ASC

Hey all,
I'll open with an example:
Lets say I have a table of students...
I can represent each line in the table as a class, which I'll write.
This Student class would contain all of the fields in the table as properties, and maybe a few more functions.
So now lets say I have another table of classes, and I want to write a complex query, which takes information from both tables.
How can I represent this kind of stuff as classes?
Thanks in advance,
Shy.

It could become something like your Class object having a collection of Student class objects.

This is more of an ASP.NET question, and you should probably be storing the intermediate results from the first two forms in Session state.
