Using DISTINCT with SELECT have effect only for one column.
But when is needed to select (or to count) queries for all rows for all columns in a table without duplicates, doesn't work.
Select DISTINCT a1,a2,a3,a4 From Y ---> results 167 rows
Select DISTINCT a4 From Y ---> " 85 rows
Any thoughts?

I have an SQL .bak file and I would only like to restore specific columns as one of the columns is a free text field and is substantially increasing the size of the file. I can't restore it due to disk space constraints so dropping the column isn't possible if I can't get the table into a database locally.

I'm trying to find a specific string (a name) and replace it with another inside of a VARCHAR(7000) field. Unfortunately, there are names like Ted and Ken that I'm trying to replace. I would like to leave words like Broken, admitted, etc... intact.
UPDATEtbl
SETBody = LEFT(REPLACE(tbl.Body, pm.OldFirstName, p.FirstName), 7000)
FROM Table tbl
JOIN Person p ON p.PersonID = tbl.PersonID
JOIN PersonMap pm ON pm.PersonID = p.PersonID AND LEN(pm.OldFirstName) > 2
WHEREtbl.Body LIKE '%[^a-z]'+pm.OldFirstName+'[., ]%
'The problem I'm running into is that the '[, ]%' in the LIKE excludes any record that ends with the FirstName because it is requiring either a space, comma or period after the name. Is there some way to add an empty string to the list of acceptable characters as that would cover any scenario in the data? I would prefer not to add all characters except space, comma and period, but I guess I could do that.

We have a sorted data that looks like the first 3 columns below, and fourth colum is what I want to create)
Shift_start meal_break shift_endShift ID
1 0 0 1
0 0 0 1
0 0 1 1
1 0 0 2
0 0 0 2
0 0 1 2
I need to find a method to assign unique Shift IDS to rows that correspond to a single shift. For instance, the first shift would begin on the first row when shift_start flag is turned on, and end on the third row when shift_end flag is turned on.
Can I do this in SQL ?...some kind of grouping ?

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

What would be the most economy solution for this WHERE, I see the code where we have covnert to 101 type on both sides of equation, which I tnink is not right.
So I'm thinking to put it on the left like this, just curiouse is this the best solution, I also heard that TSQL interpret between even better , here I'm really care abour performance.
declare @DATE DATE = '01/14/2014'
--A:
SELECT * FROM TT
WHERE CAST( TT.DATETIME AS DATE) = @DATE
--B:
SELECT * FROM TT
WHERE TT.DATETIME >= @DATE and TT.DATETIME < DATEADD(D,1,@DATE)

I have a table (represented by #Events) that holds modifications made to another table. I do have some control over the table structure and indexing. I want to pull all of the change records that were made between two dates.
The tricky part is to include the previous version of each record, which will usually be found prior to the start date in question.
The code that I have provided below works. So you can use it to easily see what should be returned. But it's very slow in production.
Any better method to pull this data together?
-- Production version of this table has 4.5 million rows (roughly 1,000 rows per day)
-- Primary key is on L4Ident (clustered)
-- nonclustered index on ProcessDate, LinkRL4
DROP TABLE dbo.#Events;
DROP TABLE dbo.#Results;
CREATE TABLE dbo.#Events (
L4Ident int IDENTITY(1,1) NOT NULL,

Can't seem to make this SQL query work!
Given one table, Table1, with columns Key1 (int), Key2 (int), and Type (varchar)...
I would like to get the rows where Type is equal to 'TypeA' and Key2 is Null that do NOT have a corresponding row in the table where Type is equal to 'TypeB' and Key2 is equal to Key1 from another row
So, given the data
**KEY1** **Key2** **Type**
1 NULL TypeA
2 5 TypeA
3 1 TypeB
4 NULL TypeA
5 NULL TypeB
I would like to return only the row where Key1 = 4 because that row meets the criteria of Type='TypeA'/Key2=NULL and does not have a corresponding row with Type='TypeB'/Key1=Key2 from another row.
I have tried this and it doesn't work...
SELECT t1.Key1, t1.Key2, t1.Type
FROM Table1 t1
WHERE t1.Key2 IS NULL
AND t1.Type LIKE 'TypeA'
AND t1.Key1 NOT IN
(SELECT Key1
FROM Table1 t2
WHERE t1.Key1 = t2.Key2
AND t1.Key1 <> t2.Key1
AND t2.Type LIKE 'TypeB')

Is there a efficient way to compare two different columns of 2 different rows in a data set as shown below.
For eg: I would like to DateDiff between Date2 of RowID 1 and Date1 of RowID 2 of IDNo 123. After this comparision , if datediff between two dates are <=14 then i want to update 1 else 0 in IsDateDiffLess14 of RowID1 . In below example its 0 because datediff of two dates >=14. So, want to compare the Date2 and Date1 in this sequence for the same IDNo. For RowID 6 there is only 1 row and no other row to compare, in this case IsDateDiffLess14 should be updated with 0.
RowID IDNo Date1 Date2 IsDateDiffLess14
1 123 04/10/2013 04/12/2013 0
2 123 05/10/2013 05/11/2013 1
3 123 05/21/2013 05/25/2013 0
4 112 01/10/2013 01/14/2013 1
5 112 01/27/2013 01/28/2013 0
6 120 03/10/2013 03/12/2013 0

I have 5 columns in my database. 1 column is coming like a dynamic.
I want to convert records from rows to columns. Currently I have a data like this.
Race AgeRange Amount
W 17-20 500
W 21-30 400
W 31-40 200
A 17-20 100
H 41-50 250
H 51-60 290
So age range is not fixed and it can be any and I have one separate relational table for age range where it's coming from. Now I want to convert it into columns like
Race 17-20 21-30 31-40 41-50 51-60
W 500 400 200 0 0
A 100 0 0 0 0
H 0 0 0 250 290

What I need to be able to find is any records where the Discontinue_Date is greater than the Effective_Date on the next row for a given Customer ID and Part_ID. This is a customer pricing table so the Discontinue_Date of row 53 for example should never be greater than the Effective_Date of row 54130, these are the records I'm looking to find. So I'm looking for a SELECT query that would look for any records where this is true. Obviously the last Discontinue_Date row for a Customer_ID will not have a next row so I wouldn't want to return that.

I currently have data stored in a temporary table and I would like to transpose the data into a better format. I would like for the query to be dynamic since one of the tables currently has over 500 columns.
The attached file provides an example of the table structure along with sample data. Below the first set of data is the desired final format.

I have this query:
SELECT TOP (100) PERCENT dbo.Filteredfs_franchise.fs_franchiseid AS FranchiseId, dbo.Filteredfs_franchise.fs_brandidname AS Brand,
dbo.Filteredfs_franchise.fs_franchisetypename AS [Franchise Type], dbo.Filteredfs_franchise.fs_franchisenumber AS [Franchise Number],
dbo.Filteredfs_franchise.fs_transactiontypename AS [Transaction Type], dbo.Filteredfs_franchise.fs_franchisestatusname AS [Status Code],
[Code] ....
I need to pivot this so I can get one row per franchiseID and multiple columns for [Franchisee Name Entity] and [Franchise Name Individual]. Each [Franchisee Name Entity] and [Franchise Name Individual] has associated percentage of ownership.
This has to be dynamic, because each FranchiseID can have anywhere from 1 to 12 respective owners and those can be any combination of of Entity and Individual. Please, see the attached example for Franchise Number 129 (that one would have 6 additional columns because there are 3 Individual owners with 1 respective Percentage of ownership).
The question is how do I PIVOT and preserve the percentage of ownership?

I am trying to create a calendar style report that will have 12 months (as columns) and store opening listing in rows. I have created a matrix, but the problem that I have is that the store opening listing displays in the right period, but they are not in any order. I would like to have the openings always on top, right under the header in the matrix. Now I have them scattered randomly all over the matrix. I tried numerous way of sorting and that does not work.
I am attaching a sample of what I would like to accomplish (months are columns).

I have a table that has for each shop a value that can change over time.For example
BK_POS 1 --> Segment A
BK_POS 1 --> Segment /
What I would like to achieve is to get all distinct Shops (BK_POS) from the table above, but if for that specific pos a row exists where the segment = "/" then I do not want to take this BK_POS in my select query.More concrete, the for example above I do not want to select BK_POS 1 because he has one row where the segment = "/".

[PersonType] [nchar](2) NOT NULL,
[FirstName] [varchar](100) NOT NULL,

This works very well, but I want to concatenate more rows with different [PersonType]-Values in different columns and I don't like the overhead, of using the same table in every subquery ([Person_1]). Is there a more elegant way to do this, without using a temp table or something else?
