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
//return new Order(reader); // "Get" pattern
}
}
// generic reader; interface implementation removed
public class GenericDataReader : IDataReader
{
// ... \\
public T Get<T>(string name)
{
int i = _dataReader.GetOrdinal(name);
if (_dataReader.IsDBNull(i))
return default(T);
else
return (T)_dataReader.GetValue(i);
}
public T Get<T>() where T : ILoadable, new()
{
T entity = new T();
entity.Load(this, false);
return entity;
}
}
// All business objects must implements this interface
public interface ILoadable
{
void Load(GenericDataReader reader, bool deep);
}
// Sample business object
class Order : ILoadable
{
int id;
Customer customer; // Note
DateTime orderDate;
DateTime requiredDate;
DateTime? shippedDate;
List<OrderDetail> orderDetails;
public Order(){ }
public Order(GenericDataReader reader)
{
Load(reader, true);
}
#region ILoadable Members
public void Load(GenericDataReader reader, bool deep)
{
id = reader.Get<int>("OrderID");
customer = reader.Get<Customer>(); // Note
orderDate = reader.Get<DateTime>("OrderDate");
requiredDate = reader.Get<DateTime>("OrderRequiredDate");
shippedDate = reader.Get<DateTime?>("OrderShippedDate");
if (deep && reader.NextResult())
{
orderDetails = new List<OrderDetail>();
while (reader.Read())
{
orderDetails.Add(reader.Get<OrderDetail>());
}
}
}
#endregion
}
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,
Rubens

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.

Check whether column yield contains any -ve value
this might result in domain error

How can i multiply all data when there is zero value?
still convert(float,exp(sum(log(yield)))) ??
Can you please help to guide me?
Thanks.

thank you

I don't think that you can change the storage format. Using Convert function would be better. If your application uses common date format in all areas, consider putting the convert inside a custom function. Use this custom function everywhere.

SQL Server stores the data in a datetime datattype (a number underneath it all), the format is only a concern of your presentation layer.
