SQL Server 2012 :: Generate Flag To Check Whether Join Condition Match Or Not
Oct 12, 2015
I want to join 2 tables, table a and table b where b is a lookup table by left outer join. my question is how can i generate a flag that show whether match or not match the join condition ?
**The lookup table b for column id and country are always not null values, and both of them are the keys to join table a. This is because same id and country can have multiples rows in table a due to update date and posting date fields.
example table a
id country area
1 China Asia
2 Thailand Asia
3 Jamaica SouthAmerica
4 Japan Asia
example table b
id country area
1 China Asia
2 Thailand SouthEastAsia
3 Jamaica SouthAmerica
5 USA America
Expected output
id country area Match
1 China Asia Y
2 Thailand SouthEastAsia Y
3 Jamaica SouthAmerica Y
4 Japan Asia N

I have a request where i would like to get the start date/time and end date/time and flag (with an int) which hours (24 hour clock) have values between the two dates. Example car comes into service on 2013-12-25 at 0800 and leaves 2013-12-25 at 1400 the difference is 6 hours and i need my table to show
Column: Hour_6 Value: 0
Column: Hour_7 Value: 0
Column: Hour_8 Value: 1
Column: Hour_9 Value: 1
Column: Hour_10 Value: 1
Column: Hour_11 Value: 1
Column: Hour_12 Value: 1
Column: Hour_13 Value: 1
Column: Hour_14 Value: 0
As i'm working away at it i'm trying to figure out how i could use a Time Dimension table for this but dont really see much. So far i have the difference between the two times in hours (hour_diff) and the start hour (min_hour) so i would like to do something where i update the first hour (min_hour) and update columns based on the numbers of hours (hour_diff)

I am upgrading my application's SQL Server from 2008 R2 to 2012.
As discussed in the below URL I am able to see the Identity jump after I upgrade and the server is restarted.
Now since I cannot afford this and at this moment I do not have the time to create a sequence with NOCACHE and test it again I have to go ahead and add trace flag 272 in the start up parameter as this is the only solution which I can implement and even rollback without much hassles.
[URL] ....
What I got to know, this flag will disable the new feature of IDENTITY property that has been implemented as part of SQL Server 2012 and will make it work like it was doing in SQL Server 2008 R2.
But I want to know implementing this flag would impact any other feature or performance (except the performance of IDENTITY) of SQL Server.

Not sure how to do this but here is example of what I have
Table A
ID data1 data2 data3 data4
1 535 452 213 554
2 325 651 321 554
3 654 846 096 355
4 765 658 321 422
I want to have a select that will pull the following information out with count = the number of rows that have matching data in data4
ID data1 count
1 535 2
2 325 2
3 654 1
4 765 1
Right now I am using a VB script to loop thru get the current data4 value then using SELECT COUNT(data1) AS count FROM tbl_toolerrors WHERE data4 = {data4 value currently looking at}
Of course this take a bunch of trips to database and I think there should be a way to do it. I was thinking of a nested SQL querry like
Select data1, data2, ID, data3, (select count ...) Order by data1
can anyone help?

I'd like to get a extract table result, with a reference id primary key, showing the maximum dates for events and who was responsible for them. I can get the max(date) field in columns using PIVOT, but can't see a way to get the 'who' field without lots of LEFT JOINs.
Here's some test data and code which shows the principle:
CREATE TABLE #t
(
ref INT ,
id INT ,
who VARCHAR(10) ,
checkin DATE
[Code] ....
The result set is:
ref 1 who1 2 who2 3 who3 4 who4
123 2014-01-18 carol 2014-01-18 andy 2014-01-16 bill 2014-01-17 carol
456 NULL NULL 2014-01-17 NULL NULL NULL NULL NULL
Is there some way to avoid all the LEFT JOINs, maybe by using another PIVOT, to produce the same result?

I am stuck with a query that I am working on. I have data like below.
DECLARE @Input TABLE
(
OrderID INT,
AccountID INT,
StatusID INT,
Value INT
)
INSERT INTO @Input VALUES (1,1,1,15), (2,1,1,20), (3,2,1,5), (4,2,2,40), (5,3,1,20), (6,1,2,40), (7,1,2,40)
If an Account's value reaches 20 for StatusID = 1 and 40 for StatusID = 2, that is a called "Good". I want to find out which order made the Account become "Good".
By looking at the data, it is understandble that AccountID 1 crossed Status ID 1's limit of 20 with order 2, but the status ID 2's limit was only crossed after the 6th order was placed. So my output should show 6 for AccountID 1.
For AccountID 2, value of statusID 1 was 5 with orderid 3, but it reached the limit for status id 2 of 40 with order 4. But the first condition was not met. so it shouldn't be seen in the output.
Same with AccountID 3 as well, It reached the limit of status id 1 with order 5 but the limit for order 2 wasn't reached so it should be ignored as well.
I wrote the code as below, its working fine but I still know there are better ways to write since I will be working with atleast a million records.
;WITH CTE AS
(
SELECT OrderID,AccountID, StatusID, SUM(Value) OVER(Partition By AccountID, StatusID ORDER BY OrderID) AS RunningTotal
FROM @Input
[Code] ....

Using MSSQL 2012
I have a simple select query and I need to eliminate records whose values from 2 different fields match. I thought I had this working, but if one of those fields in my data IS NULL it filters out those records. If I comment out my last line then my number record shows, if I include that statement that record drops. The only thing I see in my data is the Name and PName are both NULL in the data for that particular number. Just need to filter out any records where it finds those 3 Names that also have "Default" as the PName, then include everything else even if Name or Pname is NULL.
Below is my where clause.
WHERE [DETERMINATION] <> 'Denied'
AND [Number] ='A150731000039'
---- Removes incorrect records where these names match----
AND ([Name] NOT IN ('GLASSMAN','NANCY','LUDEMANN') AND [PName] = 'DEFAULT')

Is it possible to stop a query from running if a condition is not met?
I have a stored procedure that returns some email addresses. A condition is that a load of new data should have happened in the current month.
If a load of new data hasn't happened I want the stored procedure to stop and return an error message instead of returning the email addresses.
I have a variable that finds the maximum data load date and I thought I could use an IF... ELSE... to check if new data had been loaded. Like this:
DECLARE @MaxLoadDate as date = (select max(load_date)
from #table)
IF @MaxLoadDate<Dateadd(month, Datediff(month, 0, Getdate()), 0) --First Day of Current Month
<Something here to kill the query>
ELSE
SELECT email_address
FROM... etc
I've tried a couple of things like PRINT 'Error', and SET NO EXEC ON, but the query seems to happily carry on past the IF condition and return the email addresses. I know that data hasn't been loaded this month, so it should fail.

I have a very simple query like the following…
SELECT table2.column_code2,
table2.column_description2,
table2.column_code1,
table1.column_description1
FROM database_001.table2 table1 LFET OUTER JOIN database_001.table2 table1 on (table2.column_code1 = table1.column_code1)
From this query, its returning me a result set of something like below:
--------------------------------------------------------------------------------------------------
column_code1 column_description1 column_code2 column_description2
--------------------------------------------------------------------------------------------------
RO1 BOOK RL1 PDF/ECOPY
RO2 PAPER RL2 CONFERENCE
RO5 JOURNAL RL11 OTHER
Now, on the above query I want to insert three extra columns with the name (status, location and contact) where the results in the extra three columns would be based on the conditions I want to define in the query based on the above results…
Something for example (I am not trying to write a condition: my question is how to write it),
if column_code1 = RO1 and column_description2 = PDF/ECOPY on status column it should return a value ‘ONLINE’ & on location column it should return ‘WEB’ and on contact column it should write ‘BOB’.
Also, if column_code1 = RO5 and column_description1 = JOURNAL on status column it should return a value ‘ON PRESS FOR PRINT’ & on location column it should return ‘S.R STREET, LONDON’ and on contact column it should write ‘SMITH’ like below result…so the final output should be the top four columns and the extra three columns…
See the attachment for better formatting...
---------------------------------------------------------------------------------------------
status location contact
---------------------------------------------------------------------------------------------
ONLINE WEB BOB
ON PRESS FOR PRINT S.R STREET, LONDON SMITH

I want to identify rows that go negative but only for 2 cents or more as well as identify rows that 2 or more.
I have this expression that does not work how I want it to work:
CASE
WHEN (SUM(FavUnfavCostChange) < (2/100) THEN 'Less'
WHEN SUM(FavUnfavCostChange) > (2/100) THEN 'More'
ELSE NULL
END AS 'Flag'
But I get:
0.00000815000000000000More -- this is not more than 2 cents, is just a positive number
-0.00094700000000000000Less -- this is not less than 2 cents, is just negative number
-0.00222000000000000000Less -- this is not less than 2 cents, is just negative number
-0.00012250000000000000Less -- this is not less than 2 cents, is just negative number
0.00000000000000000000NULL -- this is zero so null is fine
0.01188576000000000000More -- this is not more than 2 cents, is just a positive number

Lets say I have a set of columns as follows:
Table.Name - Table.ID - Table.Code
I want to write a query that will cycle through the results and if it comes across another record that has a matching Table.ID I want to exclude that row from the result set.
I am not all too familiar with how to use either a Case or If..Else Statement within a Sql statement that would accomplish this.

Hi,
I have a data-flow-task that imports data to sqlserver.
Now I want to check, if a special column of an imported record is null.
If yes, I have to wait 10 minutes and jump to the data-flow-task again. (Cjeck and wait).
How can I do this with the integration services?
Thanks

Here's my predicament. I changed the filter on an article within a subscription, but not in a meaningful way. I just added "database.dbo." before a column name, but now my subscription is flagged for reinitialization, and won't replicate any transactions unless I start over with a new snapshot. I don't want that to happen. How can I reset the article properties somewhere to get it back the way it was and continue replicating transactions.
(I needed to add "database.dbo" so that another job that looks at the filter info would point to the correct database. Next time maybe I'll just modify the table that stores the filter info)
The reason I don't want to snapshot from the beginning is that I have procedures on the subscribing server that fire triggers from the transactions, so all the jobs "downstream" would get all out of sync.
HELP !

After carefully analyzing the situation for almost a month, I pulled the trigger and made an exception at work; we did enable trace flag 2371. We have some tables with billion of rows and outdated statistics causing horrible plans. Tried several methods to update those, but did not solve the problem or was too CPU intensive, causing other issues.
Anyway, one of the side effects I am seeing so far is average vCPU went down by almost 40%. Nothing out of usual (besides the flag) has been enabled or was executed. So my assumption is, CPU hungry plans are now gone or reduced.

We need to create a pdf file from SQL server preferably from a stored procedure. Application will call the stored procedure and it should generate pdf. From my research it appears it can be done using various external tools with licensing/costs. But is it possible to do this within sql server database without additional costs? I read that this can be done by SSRS in SQL server but not sure if it is a good solution and if it is additional licensing..

I have a view where I am joining two very large tables.
I am joining where Brand and then Product match.
My problem is that there are quite a few rows where there is a Brand and Product in Table A but it is not in Table B and the other way around, Products in B that aren't in A and I need ALL of the products to show, not just the ones that are in both tables.
The field names are the same in each table, one is North America and the other is Europe. HOW do I write that?
SELECT
dbo.SummaryNA.Brand,
dbo.SummaryNA.Product,
dbo.SummaryEU.Brand AS Expr1,
dbo.SummaryEU.Product AS Expr2,
dbo.SummaryNA.Supplier,
