Well - I'd start by gathering requirements, working out what fields need to be in the database and then normalize it to at least third normal form. Here's a technical hint for you - consider investing in some paper and pencils for your design.

You need to do alot of planning, investigation and searching (on the web). If you don't know how to design the database and tables I agree with the other person find out for yourself. You'll get alot more satisfaction if you've done the work yourself. Trust me I know!

Hi All,
I wanted to go for the OCP. Can any one please let me know How many exams I have to give? Which are the exams and the fees structure? And from where I can give this exam and how to pay the fees of the exams. I wanted to do OCP in 9i or 11i.
Thanks,
RK

Have you tried looking on the Oracle web site? I bet they have loads of information about OCP

Hi, I have the following problem,
I have 2 different databases for 2 seperate systems I some of the data in db 2 is needed in db 1, I want to create an sql trigger for ms sql 2000 that will run when ever an update happens in db 2 the fields that I want in db 1 from db 2 must update with the changes made in db 2.
So my problem is in the trigger how to I get the values that where updated into the update stament I want to send to the other database
CREATE TRIGGER tr_table_UPDATE
ON dbo.vehicle_db1.Vechicle_list
FOR UPDATE
AS
Update dbo.vehicle_db2.Vechicles set Registration_No = 'PYS 789 GP', Model = 'Data from the original update' where ID = 'id from original update'
I hope this makes sense, in a way its kinda replication.
Thank in adavance.

If the databases are on the same server then there is no need to replicate the tables because you can reference tables using:
select * from <database>.<owner>.<table> If the databases are on separate servers, but have reliable connectivity then consider using "linked servers" (look them up in BOL).
Otherwise consider using "replication" (look it up in BOL).
Hope that helps.

I have a table having columns like values, like this
col1 col2 col3
1000 10 2
1000 20 3
1000 30 4
2000 10 5
2000 20 6
2000 30 7
3000 10 8
3000 20 9
3000 30 10
I want to fetch records like if i enter col2 as 20 and col1 as 1500 then
with
"SELECT col3 FROM table1 WHERE col2 = @col2"
I will get 3 rows having respective records of value 20 for col2(col2 values are fixed)
but col1 values are variable i.e. can fall into different ranges like 1400,1500,2300 etc.
but col2 values are fixed
I want to return only one row for eg. col2 as 20 and col1 as 1500
then
1000 20 3
this row should get returned
How can i do this?
I don't know how to use cursors...

No issues to learn...
I am just asking is there anyone have idea to do it in optimized way?
as I am trying
col1 have variable inputs like 1200,1300,2100 etc...
and col2 have fixed inputs
I am doing like this calculating min and max values for col1
and trying to put col2 in that range
but till I m not able to achieve...

There's no problem in using a cursor within a while loop -> have a look at the MSDN, to review the example and you'll have your're problem solved.

I am not sure about NVarchar, but if you were using DateTime type, use convert function to change the display format.

Well, a couple of sample dates would have done rather than dozens, but your answer is:
Using @a to represent your column
<br />
declare @a nvarchar(50)<br />
set @a = '28/10/2008'<br />
set dateformat dmy<br />
select convert(varchar,datepart(day,@a)) + '/' + left(datename(month,@a),3) + '/' + convert(varchar,datepart(year,@a))
You need the set dateformat dmy so SQL knows its day month year

actually i have five columns like system,name,qty,weight,area
I have to fetch the details from database. I have to write a query where i have to multiply qty and weight and put it in weight column and at the same time i have to display the records in the descending order of total weight . How can this be done. Please help
skd

|
|
|
|
It's a home work question, how about this
SELECT
[system]
,[name]
,[qty] * [weight] As TotalWeight
FROM
[dbo].[TestTable]
ORDER BY
TotalWeight DESC

Hi there,
I'm looking for some advise for a generic data fetch pattern for IDataReader I'm working on, as follow:
// main load
using(GenericDataReader reader = new GenericDataReader(cm.ExecuteReader()))
{
while (reader.Read())
{
orders.Add(reader.Get<Order>()); // "GetList" pattern

What do you think? Are there any major drawback with this model I'm missing? Are there any more clever way to do that?
I really appreciate your time reading this. Thanks in advance,

Seems a nice idea. Just when you are done, try to post a article on CodeProject.
Good Luck,

Hi Mehroz,
I'm working on some model limitations and, when I ready to go, I'll post @ CP, for sure.
Thanks for your incentive,

Hi All
We know the ALTER TABLE ADD <columnname> adds the column on the end of the table. There have been posts about how to add it in the middle, and people agree it can't be done easily, and doesn't need to be done.
The application doesn't care about the order, but...
I am a little pedantic, and like everything neat and tidy. I like my PK first, then my FK's, then some logical group as we move down the table definition. So, when I add a new column that will form a FK, I don't want it on the end.
It looks better on a database diagram, and makes the data easier to read in a select * from ...
That said, am I hanging on to an ideal that I shouldn't be? Is adding a column 3 from the top using EM causing overhead in my DB by copying the table and data, then copying it back?
I am interested in people's opinions on keeping the database logically grouped.
Thanks
Brent

Hi. I am trying to figure out how to write a select statement that will retrieve all entries that have a certian letter combination in. EG: If the user enters "a" it will retrieve all words starting with an "a". if he enters "ad" it will return all words stsrting with "ad" etc. Please advise 
|
|
|
|
|
Select * from Table Where Field like 'a%'
Select * from Table Where Field like 'ad%'
Is that what you are asking for? If it is, you might want to google next time before you ask, it's pretty basic.

Hi
How can i combine the follow SQL statements? Without compromising on performance.
<br />
select ppar_engparameters.parmval, ppar_engparameters.parmname<br />
from ppar_engparameters<br />
where ppar_engparameters.prcdversion = (select max(prcd.prcdversion) from prcd where<br />
prcd.prcdname = ppar_engparameters.prcdname and prcd.activeflag='A') and <br />
ppar_engparameters.parmval='myValue' <br />
<br />
<code>select category from catg_pll<br />
where catgnumber = 01 and partprcdname||' '||partprcdversion = 'myValue2'
select catg_pll.category, prcd.activeflag, prcd.prodstatus from catg_pll, prcd<br />
where prcd.prcdname||' '||prcd.prcdversion = 'myValue2'<br />
and catgnumber = '05' and <br />
catg_pll.partprcdname||' '||catg_pll.partprcdversion = 'myValue2'<br />

Hi,
I'm facing this problem which i don't know how to solve it.
Can anyone guide me?
I have a list of data in table @tmp1. Format like below. This table consists > 100 rows of data.
Format:
PartID PartNumber Yield
866 A100 0.98154735437972429
866 A100 0.9997734994337486
866 A100 0.99168797953964194
868 A200 0.70783730158730163
868 A200 0.99929971988795518
868 A200 0.99889908256880733
When i run this query,
select partid,partnumber,convert(float,exp(sum(log(yield))))
from @tmp1
group by partid,partnumber
Error encountered.Error message is "A domain error occurred".
I'm trying to multiply all data from 'Yield' column. That's why i query with
convert(float,exp(sum(log(yield))))
But I suspect convert(float,exp(sum(log(yield)))) is giving the error.
So I tried to change datatype to int or varchar or decimal.
But still cannot be solved.
Pls help me.
Thanks in advance.
