GPS,



Since you have such a dependency on dates and date calculations, you should implement a calendar table. A calendar table will make calculation such as this much more simplistic.



Calendar table link http://sqlserver2000.databases.aspfaq.com/why-should-i-consider-using-an-auxiliary-calendar-table.html.

Note the calendar table I use is a little different than this one. The only thing you will need to change is isodate to dt.


Now the code to get the results you need:



Code Snippet
declare @t table(
id int,
fname char(4),
Start_Date datetime,
End_Date datetime,
val_holiday int
)
insert into @t values (111, 'aaaa', '3/15/2008', '03/21/2008', 1 )
insert into @t values (222, 'bbbb', '05/2/2008', '05/9/2008', 3)
insert into @t values (333, 'cccc', '04/3/2008', '05/15/2008', 4)
insert into @t values (333, 'cccc', '04/29/2008', '07/07/2008', 1 )

select id, fname, cal.ISODate, val_holiday
from @t t1

inner join Calendar cal
on cal.isodate >= t1.start_date and
cal.ISODate <= t1.end_date







is possible to do it

Query Within Query - Checking For Multiple Fields

Jun 9, 2008

Hi,
I remember seeing a fancy query that checked for multiple fields in a table (I think using a select statement in the where clause but not sure), but can't remember how to do it... here is what I want to do (and maybe there is a much easier way). Thanks!

Table1
id item color
1 shoe red
2 shoe blue
3 coat green
4 coat black

Table2
item color
shoe red
coat green

I want everything in Table1 where item and color are not a match.

So my results should be:
2 shoe blue
4 coat black

I'm sorry if this is a dumb question... it's been that kind of a day!

Thanks!

Hello all,

I have a branch a data, now i need to search through a database to check whther it is exist in that database or not, any syggestion?
Example:

Now i have data 123, 234, 345. Let say data 123 and 234 is exist in that database, but data 345 is not exist in that database.

What SQL am i suitable to use to get those result exist(123, 234) and those result not exist (345)?

The database structure is someting like this:
ID NAME O_NAME
-- ----- --------
1 120 123
2 234 234
3 345 345

1) The data consider 'exist' if it exist in column NAME or column O_NAME (either one).

2) The data consider 'not exist' if it not exist in neither NAME column nor O_NAME column

After the SQL query, someting is expected:

Exist:

ID NAME O_NAME

2 234 234

Not Exist:

ID NAME O_NAME
-- ----- --------

Subreports: Parameter Value Dropdown Shows Sum And Count Fields But Not The Actual Data Fields.

Jan 28, 2008


I have just started using SQL Server reporting services and am stuck with creating subreports.

I have a added a sub report to the main report. When I right click on the sub report, go to properties -> Parameters, and click on the dropdown for Parameter Value, I see all Sum and Count fields but not the data fields.

For example, In the dropdownlist for the Parameter value, I see Sum(Fields!TASK_ID.Value, "AppTest"), Count(Fields!TASK_NAME.Value, "CammpTest") but not Fields!TASK_NAME.Value, Fields!TASK_ID.Value which are the fields retrieved from the dataset assigned to the subreport.

When I manually change the parameter value to Fields!TASK_ID.Value, and try to preview the report, I get Error: Subreport could not be shown. I have no idea what the underlying issue is but am guessing that it's because the field - Fields!TASK_ID.Value is not in the dropdown but am trying to link the main report and sub report with this field.

Am I missing something here? Any help is appreciated.

Thanks,
Sirisha

Transact SQL :: Get One Row From Multiple Based On Fields And Also Get Sum Of Decimal Fields?

Jul 2, 2015

I am using MS SQL 2012.  I have a table that contains all the data that I need, but I need to summarize the data and also add up decimal fields while at it.  Then I need a total of those added decimal fields. My data is like this:

I have Providers, a unique ID that Providers will have multiples of, and then decimal fields. Here are my fields:

ID, provider_name, uniq_id, total_spent, total_earned

Here is sample data:

1, Harbor, A07B8, 500.00, 1200.00
2, Harbor, A07B8, 400.00, 800.00
3, Harbor, B01C8, 600.00, 700.00
4, Harbor, B01C8, 300.00, 1100,00
5, LifeLine, L01D8, 700.00, 1300.00
6, LifeLine, L01D8, 200.00, 800.00

I need the results to be just 3 lines:

Harbor, A07B8, 900.00, 2000.00
Harbor, B01C8, 900.00, 1800.00
LifeLine, L01D8, 900.00, 2100.00

But then I would need the totals for the Provider, so:

Harbor, 1800.00, 3800.00

Update Fields With Data From Other Fields In Same Row

Jun 30, 2000

Pardon me if this question is too elementary. I am trying to create a trigger that will cause certain datafields to be updated with values from other data fields in the same row when a certain column, created specifically to fire the trigger, is updated. The purpose of this is to reduce data entry by field personnel.I think I have the create trigger statement correct, but I'm a little confused on the update statement.

In a nutshell, how can I write something like:
UPDATE "TABLENAME"
SET DATAFIELD1 = DATAFIELD2
WHERE RECORDNUMBER = (THE SAME RECORD NUMBER)

I do know that I have to ensure that sp_dboption Recursive Triggers value is set to false, thanks.

Using LIKE To Find Any Of Fields In One Table In Fields Of Another

Jul 31, 2013

I have a list of items in one table and a field (pageName) in another table that may contain one of the aforementioned items somewhere within that field. There is no fixed position within the field where the itemNo may be so I can't just use SUBSTRING(pageName,2,5) in(select itemNo from tblItem).

Logically, it's like I need to combine IN and LIKE: select pageName where pageName LIKE IN %select itemNo from tblitemNo%..LIKE can only handle one comparison string.

Drillthrough In Calculated Fields Enable When Drillthrough Option Is Disable In Original Fields, Is This A BUG?

Jan 21, 2008

Hi people
My users are having troubles with link to default drillthrough report when reports are exported to excel (they REALLY don't like this behavior ), so I decided set all of them disabled in report model, this work fine, but calculated field in reports has this drillthrough link.


Let me show you the situation. Entity Product has an UnitaryCost field, I set the EnableDrillthrough Property in False so when I export a report with this field, no link is shown.

But if I create in the report a calculated field Round(UnitaryCost) this field has a Drillthrough Link

Is this the standard and expected behavior? or its simply a BUG?

Have I done something wrong in my model? and in this case, How I can correct this?

regards.
Julio Diaz.

Checking For PK

Feb 10, 2004

Hi,

I want to assign a list columns to be the PK on a table. I don't know what this list of columns would be.How do I go about figuring that?

Sample Data

Col1...Col2...Col3..Col4
1...........2.......A......X
1...........2........B.....X
1...........2.......A......Y



As you can see Col1 & Col2 ONLY do not make up the PK. I need to include Col3 as well. My concern is I am not sure if I have a row like..
1...........2.......A......X reapeated lower down the order. So how do I figure the PK out?

Thanks

Checking For Row Existence

Nov 1, 2006

Can someone show me some C# code for detecting if a SQL row exists or not?  This seems like a very typical action and I cannot for the life of me find a tutorial online that explains this step.  In my code I'm either going to INSERT or UPDATE a record.  I tried sending a SELECT command through a ExecuteNonQuery, but only got -1 as a response.  Apparently ExecuteNonQuery does not work with SELECT.  I then saw that T-SQL has an EXISTS keyword, but I cannot see anyway to use that from within C#.So...can anyone share the typical code they use to identify if a row exists or not within a database.  I guess I was execting there to be some method available to do this sort of thing.

Checking Character Set

May 2, 2002

I've forgotten the character set that I've chosen when I was installing the SQL Server 7. Is there a way to check?

I'm currently using US English version of Windows NT4 and SQL7. But interestingly, all the data is in Japanes characters. It's actually for a Japanese website, and the front-end application is written in ASP. I remember reading somewhere that it is impossible to do certain type of sorting (by some particular order for the Japanese language) as it is limited by the choice of the language of the NT OS.

The type of sorting that I'm looking at is the grouping of 5-characters. One example is in http://www.forest.impress.co.jp/aiueo.html

Would this be possible with my current setup? Or would it help if I migrate over to Windows 2000? (I'd rather not move to Japanese NT4)

Your feedback and advice would be very much appreciated!

I want to do a check to see if a number falls within a range specified by the user. Basically, they enter in a min and max value and I return a hit if a number falls inbetween.

Code:

SELECT DISTINCT *
FROM Table
WHERE ( (0=0)

(min.value <= Table.Value <= max.value) )


(This isn't my actual code, but just the logic)

It will return all the results everytime. Does anyone have any suggestions on what I could be missing here?

Checking Job Status Using SQL-DMO

Jun 27, 2004

I have a question I hope someone can help me with.

My situation:
I have a single-step job in SQL Server, which runs a stored procedure, A. This stored procedure invokes another stored procedure, B. In B, one of the statements is a 'BACKUP DATABASE' command, and a database is backed up to a file.

The job is started by an application. Once started, the application then uses the SQL-DMO property CurrentRunStatus to periodically check the status of the job. When the property returns the value SQLDMOJobExecution_Idle (indicating the job has completed), the application code then continues processing, and attempts to access the .dat file produced by the 'BACKUP DATABASE' command.

My problem:
On occasion, the application will hit the problem where either the backup file cannot be located, or the file is still being locked by another process (Error=The process cannot access the file because it is being used by another process).

Is anyone able to shed some light on this?

I assume that the job will only return a completed status after:
(a) both A and B have completed execution, and
(b) the BACKUP operation has completed

Is it possible that even though SQL Server indicates the job has finished, that the BACKUP operation still hasn't completely ended?

Thanks for any help,
Andrew
