Transact SQL :: Find Unique Rows In Column That Are Associated With Another Field In Another Column?
May 1, 2015I 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

Help Me Getting A Unique Combination From Table
Jun 18, 2004Hi, I have following table
BetId GameId
==== ======
500 108
500 109
501 108
501 109
501 110
502 108

My query would have the form: select BetId where GameId in(108,109)
from Bets then it has to get me BetId : 500 and 502.
Not 501,since this is different combination(108,109,110) ;)
How To Get Unique Combination Of Rows
Jun 18, 2004Hi,
Following is my table:Bets
BetId GameID
500 108
500 109
501 108
501 109
501 110

I want BetId 500 and 502 to be returned as result if i give select

BetId 501.not the 500 and 502..which is different combination..
Hope i clarified my problem..pls help me in this regard.Thanks a lot...

Transact SQL :: How To Find If A Column Is Used Anywhere In Database
Oct 20, 2015I have looked around quite a bit, but mostly what I have found is looking to see if a table is used or if a column is in a stored procedure and honestly most of what I have seen does not work.
I want to reduce our nightly import by removing any columns that are not being used. We insert into our staging tables, Stage1 for example. And say Stage1 has column1 and column2. If those columns are not being used, then I want to remove them from Stage1. The only catch is that every Stage1 table has a v_Stage1. v_Stage1 should have all the columns from Stage1, but doesn't always. So I need to know what columns from Stage1 are used somewhere other than v_Stage1 and what columns from v_Stage1 are not used.
SQL Server 2012 :: Stored Procedure - Find Invalid Combination
Sep 30, 2015I have a scenario where I need to develop a stored proc to identify invalid input provided.
Following is a sample scenario

insert into Product
select 'Prod1',10,'Black' union ALL
select 'Prod1',10,'BLue' union ALL
select 'Prod2',20,'Green' union ALL
select 'Prod2',10,'Black' ;
[Code] ....
In following TSql Code , Color and Size are optional. Both are provided as comma separated input. I have provided "bbc" as wrong color and "MM" as wrong size. I want to identify if color is invalid or size (MM is in valid for Black and Blue) and to set flag accordingly.
I had tried out join but it is not serving needs.
---===========================================

DECLARE
@ProdId varchar(10),
@color varchar(max) = Null,
@size varchar(max) = Null

Transact SQL :: Comparing 2 Records / Multiple Instances In The Same Table For A Specific Combination?
Jun 10, 2015I have a problem where I have 2 compare 2 records from the same table. This part looks easy but the problem is for a User there can be multiple records and I have 2 compare each record with its previous instance based on the timestamp. Not only I have to compare I have to perform some analysis. Below is the Table script and sample output.
Givens: All SQL Server 2008 or 2012 tools at your disposal.
Production database contains the following tables (simplified for example: constraints ignored, etc.) associated with a racing video game’s server.
-- A player of our game
-- Table greater than 10 million rows
CREATE
TABLE [dbo].[User]
(
[UserId]
[bigint] NOT
NULL
,[country]
[int] NULL
-- User’s home country
,[name]
[nvarchar](15)
NULL -- User’s displayable name (‘John’, ‘Bill’)
,[subscriptionTier]
[int] NULL
)
-- 0 == free, 1 == paid, for instance
Assume that rows get written into the event tables at a rate of 1,000 a minute,are never updated once written and currently are only read on a replica/reporting server.
Question Background: Write up a single query that would return the following: List of users and whose “TotalMoneyEarned” value ever grew (between logon events) at a rate of more than 1,000 per minute (we’d consider these suspicious and flag them for later investigation).
For instance, if the sample data were:
-- example of [Events.UserLogon] data -- not the query output we want
EventId UserId TotalMoneyEarned LogonDate
----------- -------------------- ---------------- -----------------------
1 1 1000 2010-10-16 00:19:56.460
2 1 1500 2010-10-16 00:20:56.460
3 1 3000 2010-10-16 00:21:56.460
4 1 10000 2010-10-16 00:29:56.460
Event 1 is okay because there’s nothing to compare it against
Event 2 is okay because the TotalMoneyEarned only grew 500 in a minute
Event 3 should be flagged, as the value grew 1500 in a minute
Event 4 is okay, as it grew 7,000 in 8 minutes (< 1000 per minute)
Query Output (your query should return data in a format like this):
User Flagged Logon Time Rate Since Last Logon (money/minute)
John 2010-10-16 00:21:56 1500
Dave 2010-10-16 00:30:50 3200
Bill 2010-10-16 00:35:23 1000
It is likely that you will need to create sample data for both the User and [Events.Logon] tables. We are looking for a single query that returns data like what is represented in Query Output.
Transact SQL :: Find Unmatching Columns Between Two Tables While Applying A Change Column Prefix Table
Nov 16, 2015For our ETL process, we maintain a TransformationList table that has the source view and the destination table. Data is copied from the view into the table (INSERT INTO). I am trying to find column names in the Views that are not column names in the associated Table.
In the below example, want to end up with three records:
1, View1, Column4
2, View2, Column4
2, View2, Column5
I have it almost working, except that there is a table, ChangeColPrefix table, that is used by the ETL process to change some of the view's column name prefixes. Some of the source views have column names with prefixes that do not match the destination table column names. Say view SouthBase has all the column names prefixed with SB - like SBAcct, SBName. And the Destination table of Area District has ADAcct, ADName. There would be a row in the ChangeColPrefix for SouthBase, SB, AD, 1, 2 that would be used by the ETL process to create the INSERT INTO Area District From SouthBase.
I need to use this ChangeColPreifx to find my unmatching columns between my source views and destination tables. With out that table SBAcct and SBName from SouthBase will not appear to match the columns of ADAcct and ADName, but they do match.
I want to end up with these three records as non-matching:
View1, Column4
View2, Column4
View2, Column5
View1 has Salumn2 and View2 has Salumn5, and they must be changed to Column2 and Column5 as per the ChangeColPrefix table before running the Select from INFORMATION_SCHEMA.COLUMNS EXCEPT Select from INFORMATION_SCHEMA.COLUMNS looking for unmatched columns.
/***** Set Up Test Data *****/
-- Create 2 test views
IF EXISTS(SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[View1]'))
DROP VIEW dbo.[View1]
GO
CREATE VIEW View1
AS SELECT '1' AS Column1 , '2' AS Salumn2 , '4' AS Column4;

Error Number For Duplicate Column Value During An Insert For A Unique Column ?

Transact SQL :: Set Unique Random Number
Dec 1, 2015Lets say we have a table (tblProducts)
ID Item RandomNumber
-------------------------------------------
1 JEANS 1234567
2 SHIRT 72813550
3 HOOD Null
4 TROUSER 72191839
5 BLAZER 0
I want to perform a query so that SQL should look for RandomNumber Values and set a Unique Random Number Where RandomNumber Value is Null or 0.So I have got a solution as one of the MSDN Member shared the below query
select id,item,RandomNumber=Case when RandomNumber=0 then (select floor(rand()*100000000-1))
when RandomNumber is null then (select floor(rand()*100000000-1))
else RandomNumber end from tblProducts
So, can you all confirm me, that performing this query ensures that if a Value is assigned to one of the Item in RandomNumber Column, that value will not be assignend to any other Item in RandoNumberColumn.

Transact SQL :: UPDATE Statement Failing On Unique Key Constraint
Jul 9, 2015I'm trying to update rows in a simple table that has a UNIQUE KEY CONSTRAINT defined on one of its columns. Here is the DDL for the table:
CREATE TABLE [dbo].[SEC_USER](
[SEC_USER_ID] [int] IDENTITY(1,1) NOT NULL,
[USER_CODE] [varchar](100) NOT NULL,
[USER_NAME] [varchar](128) NOT NULL,
[EMP_CODE] [varchar](6) NOT NULL,
[Code] ....
When trying to execute the UPDATE statement the query fails with a constraint violation error:
Violation of UNIQUE KEY constraint 'UQ__SEC_USER__A039F1EE62FE8444'. Cannot insert duplicate key in object 'dbo.SEC_USER'. The duplicate key value is (34337).
What has me baffled is that I'm not doing any insert. Also, the value that it's referencing - 34337 - doesn't exist in the table at all. I'd rather not drop the constraint.
