Distinct Row Count In A Table.

Aug 30, 2006

Hi,

I want a count of distinct rows in a table through a single query -- is it possible?

eg.

table-

create table ch1 (a int, b int, c int, d int)

insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,3,4,5)

Here distinct row count in a table is 3 which I want to achieve thro a query.

if I do

select count(distinct a) from ch1 it works fine and gives me output as 2.

but this is not working

select count(distinct a,b,c,d) from ch1 - any workaround to find the distinct row count in a table??

Please reply.

Cheers!
Ram.

Transact SQL :: COUNT And SUM Of Multiple Columns

Sep 2, 2015

I'm working on a data analysis involving a table with a large number of records (close to 2 million). I'm using only three of the columns in the table and basically am grouping results based on different criteria. The three columns are PWSID, Installation and AccountType. I have to Provide the PWSID column with a count of the total number of installations per PWSID, also a count of AccountTypes per PWSID. I have the following query, but the numbers aren't adding up and I'm not sure why. I'm falling short in the total count by around 60k records.

CREATE TABLE [dbo].[CATASTRO_PSWID_SHPMUNINEW](
[Installation] [numeric](38, 8) NULL,
[AccountType] [nvarchar](50) NULL,
[PWSID] [smallint] NULL,
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

Transact SQL :: How To Select Columns That Are Not In GROUP BY And Get COUNT

Jul 3, 2015

I am using SQL 2012. I have a GROUP BY and I want to select two other fields from my table at the same time: One column that is a string (account_code) and one that I need to perform a count on (customer_number). I know the code COUNT(DISTINCT customer_number) works for getting that. I need to select both of those fields on top of what I have. I have the following:

DECLARE @Providers TABLE (ID INT IDENTITY(1,1),
Provider_Name VARCHAR(20),
Uniq_Id VARCHAR(10),
Total_Spent MONEY,
Total_Earned MONEY)
INSERT INTO @Providers (Provider_Name, Uniq_Id,Total_Spent,
Total_Earned)

Count Distinct In Large Table With 30M Records?

Jul 7, 2015

I have a task to count distinct records in a big table with roughly 30M records, performance is an important factor. Query is to be written to calculate weekly stats, weekly record number could be as high as 1M.

The actual result is like:
ID Policy
350235744Credit Cards
350235744PCI
350235744PCI Audit

So the final number for this particular Policy is 3

I can write the query like:

select count(distinct Incident_id) policy_name
from Reporting_DailyDlpDetail
Where (year(INSERT_DETECT_TS)=2015) and (month(INSERT_DETECT_TS) =6) and (day(INSERT_DETECT_TS) between 2 and 9)
This returns 526254 and costs 11 seconds to complete

or a query like:
Select distinct Incident_id, policy_name
from Reporting_DailyDlpDetail
Where (year(INSERT_DETECT_TS)=2015) and (month(INSERT_DETECT_TS) =6) and (day(INSERT_DETECT_TS) between 2 and 9)
This returns 749687 and costs roughly 1 minute to complete.

Result is different from the two queries, I believe the later gives correct number. How can I count the distinct based on a combo?Considering the size of data, what is the best and most efficient way to run the stats calculation against over 30 different scenarios (different policies and alert types) and not timeout?

Transact SQL :: Getting Distinct Row With Min Date From Other Table?

there is a many to many relation between the tables. Each Policy can have 1 or many Liability Constraints. Each Liability Constraint can be attached to 1 or many policies.

What I need to do is get the distinct combination of LcCode, LcDesc, LcAmt, LcFreq and LcSetId from the Liability table as well as the earliest PolInceptionDt from any of the policies associated with the Liability Constraint using only the distinct combination of LcCode, LcDesc, LcAmt, and LcFreq.

Give the data above, I would need to end up with the following result:

I tried to use the Row_Number functionand join using PolNum, but I keep getting the wrong results back.

Transact SQL :: Inserting Distinct Data From One Table To Another

Aug 19, 2015

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?

Transact SQL :: Select And Parse Json Data From 2 Columns Into Multiple Columns In A Table?

Apr 29, 2015

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:

I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.

1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.

SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B

If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.

2. My second question: How to i get around this error?

SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, fnSplitJson2(A.ITEM6,NULL) C

I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.

Select DISTINCT On Multiple Columns Is Not Returning Distinct Rows?

Jul 6, 2007

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?

Transact SQL :: Adding New Columns To Server 2012 Table

Apr 28, 2015

I am planning to add some new columns to an existing sql server 2012 table. I know that I need to use the alter statement to accomplish this goal. However my questions is the location of where I want to add the new columns to the table. It would make more sense to add the new columns to the middle of the table since these columns have a similar meaning as other columns in the middle of the table.However is it better to add these new columns at the end of the table? I am asking this question since I am thinking I might need some sql to move the values of existing columns and values around?Thus is it better to add new columns to a table in the middle of the table, at the end of the table, or at the end of the table? If so, can you tell me why one location is better than another location?
