hi
i imported an ms access db to SQL SERVER 2000 using the tool "import and export data".
Now all my relations from my access db are not shown or created in the sql server db.
How does this come? Is there a way to also import the relations? or do i have to lay them back one by one by hand?
grtz & thx

Yes, in SQL Server it is called bit

That's a vig vague. What do you want to know?
The base datatypes are:
binary Bigint bit Char datetime decimal Float image Int Money
nchar Ntext nvarchar Numeric Real smalldatetime smallint smallmoney sql_variant sysname text timestamp tinyint varbinary varchar uniqueidentifier

I have a table on an SQLServer 2000 box with a DateTime field called CallTime.
I want to select all the records between 19:00 and 06:59 over a period of days
Is there a more efficent way of doing the select in a stored procedure than this,
WHERE (DATEPART(hh, dbo.JobData.calltime) * 60 + DATEPART(mi, dbo.JobData.calltime) BETWEEN
DATEPART(hh, '19:00') * 60 + DATEPART(mi, '19:00') AND DATEPART(hh, '23:59') * 60 + DATEPART(mi,
'23:59')) OR (DATEPART(hh, dbo.JobData.calltime) * 60 + DATEPART(mi, dbo.JobData.calltime) BETWEEN
DATEPART(hh, '00:00') * 60 + DATEPART(mi, '00:00') AND DATEPART(hh, '06:59') * 60 + DATEPART(mi,
'06:59'))

Thanks Colin.
Having to split the WHERE up into before midnight and after midnight seemed to a bit clunky, but it'll do the job. I really hate T-SQL somedays, feels so primitive. Here's hoping that SQLServer2005 has a few useful enhancements.

You could create an extra column to store the minutes (or seconds) since midnight. It is updated by a trigger on the table. Your query would be less complex and probably run faster too.
Thanks. I hadn't thought of that one. I may look into implementing that for the next release of the software. I'll stick with the query for now as I'm only using it to build a View to produce a report and I don't want to make too many changes.

Could you subtract out 7 hours from each DateTime value, then convert the result to a string formatting the time in AM/PM format and just keep the ones that have a PM as their time component by using a LIKE comparison? Not sure just what this SQL would look like, but I think it work.
where to_char((DateTime - 10584000),'YYYYMMDDHHMISSAM') LIKE '_____________PM'
The value of 1058400 is how many seconds are in 7 hours.

Try the CASE statement.
e.g.
select school_id,class_id,
CASE school_id
WHEN 1 THEN left(class_id,1)
ELSE left(class_id,2)
as exp1
from student
where
exp1 = @class_val
I think this will work. Sorry but I can't test it now on my machine but try and let me know.

Only to show you more examples with CASE:
select nf_item.nf_number,
case nf_item.nf_unit_abbr
when 'KGS' then nf_item.wgt_net/1000
when 'TON' then nf_item.wgt_net
end as wgt_net,
case nf_item.currency_id
when '0795' then nf_item.price_per_unit_c
else nf_item.price_unit_conv nf_master.exchange_rate
from nf_item with(nolock) where nf_item.ts_print >= 2345345345

Hello all.
I'm almost getting my head to the wall  because I can't get to the solution for a query I need to do.
Is anyone here wanting to help me ?
Let me explain the problem:
I have a table named T1 with the following structure:
ID | Subject | ParentID
This table represents info in a form of tree and when I'm at the top branch the ID and ParentID fields have the same value.
If I have the following data
ID Subject ParentID
1 Sub1 1
2 Sub2 2
3 Sub1_1 1
4 Sub1_2 1
5 Sub1_1_1 3
I want to make a query with the following result:
ID|Subject|NumberOfChildRecords
e.g.:
1 | Sub1 | 2
2 | Sub2 | 0
3 | Sub1_1 | 1
4 | Sub1_2 | 0
5 | Sub1_1_1 | 0
Is this simple to do ?
Thanks in advance for the attention you are having reading this.

I dont think it is simple... but you could certainly try something like:
Here is how you would do it using NW:
select a.employeeid, count(b.employeeid) from employees a, employees b
where a.employeeid = b.reportsto group by a.employeeid
What we have is a self referencing table. What we need to do is essentially add the table twice in the from clause with two seperate aliases and then correlate the two in the where. I should be using ANSI standard joins here, but it was quick.
so for you we need something like
select a.id, count(b.id) from T1 a, T1 b where
a.id = b.parentid group by a.id;
Let me know if this works.

we are developing an ASP.NET application with SqlServer at backend..
there are an supplier and about 3000 customer, and each customer has about 3-4 users. they are selling mobile phone counters.
while a sale occurs, we are selecting customers stock amount, if it is bigger then sale amount, we are updating its stock, and we increment suppliers stock. The query is like that :
DECLARE @StockAmount int
SELECT @StockAmount = Amont FROM Stocks WHERE CustomerId = @BuyerCustomerId
IF @StockAmount > @SaleAmount
UPDATE Stocks SET amount = @StockAmount - @SaleAmount WHERE CustomerId = @BuyerCustomerId
SELECT @SuppliersStockAmount = Amont FROM Stocks WHERE CustomerId = @SellerCustomerId
UPDATE Stocks SET amount = @StockAmount + @SaleAmount WHERE CustomerId = @SellerCustomerId
i know, each customer has got not so many users and a concurrency problem seems to be not a big possibility. but there is just a 1 supplier record and i think conlicts are possible. how can i alter this problem. after a research, i found
SELECT @SuppliersStockAmount = Amont FROM Stocks WITH (XLOCK ROWLOCK) WHERE CustomerId = @SellerCustomerId
seems to work fine for us, but it will block the row untill the transaction finishes. any approaches are appreciated. thanks.

Hi,
I want to execute a transact SQL like below
Declare @local as varchar(30)
Declare @LocalStr as varchar(50)
Set @LocalStr ='Select @local =ColumnName, * from tablename where Condition'
Exec(@LocalStr)
But it gives @local not declare error
or how can I assign the value of columnName to local variable, It should be Transact (Dynamic) as conditions are dynamic
Thanks in advance
