Transact SQL :: Strategy To Translate Column Data Into Distinct Rows
Aug 27, 2015
I am writing a query where I am identifying different scenarios where data changes between one week and the next. I've set up my result set in the following manner:
PrimaryID SKUChange DateChange LocationIdChange StateChange
10003 TRUE FALSE TRUE FALSE
etc...
The output I'd like to see would be like this:
PrimaryID Field Changed Previous Value New Value
10003 SKUName SKU12345 SKU56789
10003 LocationId Den123 NYC987
etc...
The key here being that in the initial resultset ID 10003 is represented by one row but indicates two changes, and in the final output those two changes are being represented by two distinct rows. Obviously, I will bring in the previous and new values from a source.

I have a sql table like this
event_id timestamp event_name event_score
1 3000 alarm 0.95
10 3500 alarm 0.85
5 4000 alarm 0.93
20 4200 alarm 0.87
30 5000 alarm 0.87
30 8000 alarm 0.97
40 9000 alarm 0.98
13 9700 alarm 0.98
And I am expecting output like this(With multiple rows)
event_id1 event_id2 event_id3 event_name event_score1 event_score2 event_score3
1 10 5 alarm 0.95 0.85 0.93
30 40 13 alarm 0.97 0.98 0.98
Also I have certain conditions like the timestamp difference between event_Id1 and event_Id3 < 3600 eg 1 hour

I’m looking for clearity on partition switching. The idea is to use many BULK INSERT statements into table dbo.X_n in parallel and when BULK INSERT for table dbo.X_n is completed, switch dbo.X_n into dbo.bigdaddy. I think this is the fastest way to upload a couple hundred GB of data.
In learning about partition switching (in part) from The Data Loading Performance Guide under Partition SWITCH, I hear the instructions to say copy the main table exactly to become a target. But in that same step (#1), I read that we need to change the default file group of the target (dbo.X_n) from the default file group. Then it says I need to match indexes and lists the filegroup as something we need to match with the main table.
As an overview of the partition switching strategy, I think the whole point of BULK INSERT with partitioning is to have seperate files (in same group) to enable concurrent uploading where each table has its own file. Once the upload is completed to a table (dbo.X_n) then we do the partition switch into the main table (dbo.bigdaddy). The data we just uploaded doesn’t actually move, just the metadata for it.
When I read the instructions linked above, I hear “Don’t have the same filegroup on your target as the main table. You must have the same filegroup on your target as the main table.”
Where am I disconnected?

I have a SQL Query issue you can find in SQL Fiddle
SQL FIDDLE for Demo
My query was like this
For Insert
Insert into Employee values('aa', 'T', 'qqq')
Insert into Employee values('aa' , 'F' , 'qqq')
Insert into Employee values('bb', 'F' , 'eee')
Insert into Employee values('cc' , 'T' , 'rrr')
Insert into Employee values('cc' , 'pp' , 'aaa')
Insert into Employee values('cc' , 'Zz' , 'bab')
Insert into Employee values('cc' , 'ZZ' , 'bac')
For select
select col1,MAX(col2) as Col2,Max(Col3) as Col3
from Employee
group by Col1
I supposed to get last row as
cc Zz bab
Instead I am getting
cc Zz rrr
which is wrong

Hi
I want to translate the following
SERIALNO TYPE AMOUNT
1111 1 251111 1 5 1111 1 7 1111 1 3 1111 1 101111 3 1 1111 3 2 1111 3 4 1111 3 3
2222 0 1
2222 0 7
2222 0 1
2222 1 5
2222 1 1
2222 1 2
2222 1 3
to output in the following format
SERIALNO SUM of MIN SUM of MAX
1111 50 10
2222 9 11
For each SERIALNO I want to sum the AMOUNT, spliting the columns into 2 based on TYPE
There are only ever 2 values for TYPE for eachs serial no.
I don;t need to track the value of TYPE.
I assume you would use a MIN & MAX function but Im not sure how to write this into a view.
thanks...

I am having issues trying to write a query that would provide me the unique GUID numbers associated with a distinct PID if the unique GUID's > 1. To summarize, I need a query that just shows which PID's have more than one unique GUID. A PID could have multiple GUID's that are the same, I'm looking for the PID's that have multiple GUID's that are different/unique.
Table1
GUID PID
GUID1 PID1
GUID1 PID1
GUID1 PID1
GUID2 PID1
GUID3 PID2
GUID3 PID2
GUID3 PID2
The result of the query would only have PID1 because it has two unique GUID's. PID2 would not be listed has it has the same GUID3 in each row.
Result:
PID1

I have 2 tables: Source Table - IncidentDimNew and Destination Table - IncidentDimNew with identical columns: Id and CreatedDate but the data is different.
I would like to insert distinct data from those 2 columns of 1st table into the same 2 columns into the 2nd table but I onlt want to replace the values in the 2nd table where the Created Date is > 2015-04
I compiled the code in order to get the information I want from 2 tables:
Source Table
SELECT
COUNT(Id),
LEFT(CONVERT(VARCHAR(10)), CreatedDate, 126), 7)
FROM
IncidentDimNew
[Code] ...
This is the code I wrote in order to do it
INSERT INTO IncidentDim
[Id]
,[CreatedDate]
SELECT
[Id]
,[CreatedDate]
FROM
IncidentDimNew
where left(CONVERT(VARCHAR(10), CreatedDate, 126),7) > '2015-04'
GO
But what it does it's gives the SUM of the values in the corresponding rows where the values are not null which I don't want.
So how do I leave the values as is from table IncidentDim and insert new values as it is from IncidentDimNew where the Created Date is > 2015-04?

Field is not listed as text in any of the databases it is a varchar(255) - and that can be changed if that is what causes the issue.
But here is my syntax which produces the error Msg 421, Level 16, State 1, Procedure, Line 2
The text data type cannot be selected as DISTINCT because it is not comparable.
DECLARE @c NVARCHAR(MAX)
WITH c1 AS (
SELECT [abcd] AS table_name
FROM [intranet].[dbo].[soccerfieldinfo]
where [abcd] IS NOT NULL
), c2 AS (
SELECT Row_Number() OVER (ORDER BY table_name) AS r

Hi, I have the following script segment which is failing:
CREATE TABLE #LatLong (Latitude DECIMAL, Longitude DECIMAL, PRIMARY KEY (Latitude, Longitude))
INSERT INTO #LatLong SELECT DISTINCT Latitude, Longitude FROM RGCcache
When I run it I get the following error: "Violation of PRIMARY KEY constraint 'PK__#LatLong__________7CE3D9D4'. Cannot insert duplicate key in object 'dbo.#LatLong'."
Im not sure how this is failing as when I try creating another table with 2 decimal columns and repeated values, select distinct only returns distinct pairs of values.
The failure may be related to the fact that RGCcache has about 10 million rows, but I can't see why.
Any ideas?

3,4 are the rows i have inserted now , you can see by date, likewise i have 100,000 rows(old and new combination) and now the data from excel to TableA can be imported/exported daily , hourly, weekly basis.
Now i want to find out only the rows which are imported to tableA today, or hours back, or yesterday .....
the reason is ,
Step1:get data from excel and import to tableA( this is a manual Step) and i know when the data is inserted with exact date and time.
Step2: get newly inserted rows from TableA and pass them as Parameters in Stored Procedure.( i may run step 2 after 1 hour, or after 1 day or after 1 week ,but i want only rows that are inserted )
I tried with using where Datecreated, but did work.

I am trying to compare Sales value of year 2015 with sales value of 2016 and the difference stored in alias column as Sales_growth for year 2016 , for year 2015 the alias column be as '1' similarly difference between margin of 2015 and 2016 and result stored in alias column as margin_rate in year 2016for 2015 as 1 but when there is no record for year 2015 and record present in 2016 for a given (month, SM,SG,CUST,SP) then the alias column sales_growth and margin_rate should be 100
Formula for calculation
SGR = (sales(2015)-sales (2016)) / Sales_growth(2015)
SGR = (3456.05-3603.33) /3456.05 = -0.043
MR =( margin (2015)-margin( 2016) / margin(2015)
MR = (1059.24-1053.07)/1059.24= 0.006
DECLARE @T1 TABLE
[code]....
last record : as there is no record for year 2015 and record present in 2016 for a given (month, SM,SG,CUST,SP) then the alias column sales_growth and margin_rate should be 100

I have a table 'wRelated' with the following columns
[related_id] [int]

[type_id] [int]
[related_mui] [varchar] (100)
[date_started] [smalldatetime]

data in column [mui] is repeated as the table has more than one entries for the same [mui],
The requirement is to select the distinct[mui] but value in all the other columns for the same mui should be select in the next row with null for the same [mui]
The recordset expected should be something like this.
[mui],[related_mui],[price_group_id],[date_entered],[date_ended] m123,rm345,'pr','12-10-2003',12-12-2004'

I am using SQL Server 2012 SE.I am trying to delete rows from a couple of tables (GetPersonValue has 250 million rows and I am trying to delete 50Million rows and GetPerson has 35 Million rows and I am trying to delete 20 million rows). These tables are in TX replication.The plan is to delete data older than 400 days old.
I tried to move data to new tables from the last 400 days and it took me like 11 hours. If I delete data in chunks of 500000 then its taking a long time to rebuild indexes(delete plus rebuild indexes 13 hours). Since I am using standard edition partition wont work.
find ddl below:
GO
CREATE TABLE [dbo].[GetPerson](
[GetPersonId] [uniqueidentifier] NOT NULL,
[LinedActivityPersonId] [uniqueidentifier] NOT NULL,
[CTName] [nvarchar](100) NULL,
[SNum] [nvarchar](50) NULL,
[PHPrimary] [nvarchar](50) NULL,

I have a table that is used to build rules. The rules point to other columns in other tables and usually contain only one value (i.e. ABC). But one of the options is to add a comma-separated list of SSNs (i.e. 123123123,012012012,112231122). I am trying to build a single query that allows me to leverage that list to get multiple rows from another table.
This obviously works:
SELECT * FROM vw_Person_Profile P (NOLOCK)
WHERE P.PrsnPIISSN_Chr IN ('123123123','012012012','112231122')
But this does not:
SELECT * FROM vw_Person_Profile P (NOLOCK)
WHERE P.PrsnPIISSN_Chr IN (
SELECT '''' + REPLACE(CONVERT(VARCHAR(4000),txtFieldValue), ',', ''',''') + ''''
FROM MassProcessing_Rules PR
WHERE PR.intRuleID = 10

I have been tasked with writing an update query to update a table with more than 150 million rows of data. Here are the table structures:
Source Tables :

CREATE TABLE [dbo].[OC](

[DATE DEBUT] [date] NULL,
[DATE FIN] [date] NULL,
[Code Article] [nvarchar](255) NULL,
[INSERTION] [nvarchar](255) NULL,
[Code] ....
The update requirement is as follows:
DECLARE @Counter INT=0 --This causes the @@rowcount to be > 0
while @@rowcount>0
BEGIN
SET rowcount 10000
update r
set Comp=t.Comp
[Code] ....
The update took more than 48h and didn't terminate , how to accelerate it ?

I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A:
(name phone house cost of house,zipcodecountystatecountry)
-a view will later split this large varchar string based
column b: is the source filename of the data load (varchar 256)
....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?
