Using Pivot or UnPivot to get Output Dynamically - sql
I have a table with the following structure that I want to receive output from this table dynamically. But I do not know how to use Pivot and UnPivot.
The list of fields I use is as follows.
SELECT [RoomID]

Creating Pivots based for a rowcount in SQL
I have 2 tables T1 and T2. T1 has the following columns: Id, EntityId, TypeofValue, Year, value EntityId can have 7 values: 1,2,3,4,5,100,101 Typeofvalue can have 2 values 1 indicates Actual 2 indicates Target T2 has the following columns: NoOfRecordsToDisplay I need to fetch the number of records (if existing) for Target corresponding to an Id. The record count (1 if any record is present 0 if none) for Target needs to be grouped into two categories: First having Entityid 1 and Maximum records under Second group with entityids 2,3,4,100,101 [Not 5] However, the catches are: Sometimes Target value might not be present for a year I need to get only last records for targets on the basis of NoOfRecordsToDisplay (The number of records to display comes from T2) for actual Example1: NoOfRecordsToDisplay =3, ID =123 The data below should return CountGroup1: 1, Countgroup2: 1 as Entityid 1 has least one value for target for last 3 years -2015, 2014,2013 in this case as Entityid 2 or 3 has at least 1 value for years -2015, 2014 Id EntityId TypeofValue Year Value 123 1 1 2015 55 123 1 1 2014 56 123 1 1 2013 57 123 1 1 2012 58 123 1 2 2015 50 123 1 2 2014 50 123 1 2 2013 50 123 1 2 2012 50 123 2 1 2015 55 123 2 1 2014 56 123 3 1 2015 57 123 3 1 2014 58 123 2 2 2015 55 123 2 2 2014 56 123 3 2 2015 57 124 1 1 2015 55 124 1 1 2014 56 124 2 1 2013 57 124 2 1 2012 58 124 1 2 2015 50 124 1 2 2014 50 124 2 2 2013 50 124 2 2 2012 50 Another dataset NoOfRecordsToDisplay =3, ID =123 The data below should return: CountGroup1: 0, Countgroup2: 1 as Entityid 1 has no target value for last 3 years (entityid 1 has a target value but for 2012) as Entityid 2 has at one value for target years -2015 (entityid 3 has a target value but for 2010) Id EntityId TypeofValue Year Value 123 1 1 2015 55 123 1 1 2014 56 123 1 1 2013 57 123 1 1 2012 58 123 1 2 2012 58 123 2 1 2015 55 123 2 1 2014 56 123 2 2 2015 55 123 2 2 2011 56 123 3 2 2010 57 Thank you so much for your help.

You can try join on the table Editors and Ttile_Editors using the Editor_ID that will give you the matching records and you can filter out Only for the ' Dennis McCann ' using either multiple conditions in join or the where clause as, WITHOUT WHERE SELECT DISTINCT te.title_id,ed.EDITOR_ID,ed.EDITOR_LNAME,ed.EDITOR_FNAME FROM title_editors te JOIN editors ed ON te.EDITOR_ID = ed.EDITOR_ID AND ed.EDITOR_LNAME = 'McCann' AND ed.EDITOR_FNAME = 'Dennis' ORDER BY te.title_id USing WHERE SELECT DISTINCT te.title_id,ed.EDITOR_ID,ed.EDITOR_LNAME,ed.EDITOR_FNAME FROM title_editors te JOIN editors ed ON te.EDITOR_ID = ed.EDITOR_ID WHERE ed.EDITOR_LNAME = 'McCann' AND ed.EDITOR_FNAME = 'Dennis' ORDER BY te.title_id
It would be easier with the in operator: SELECT DISTINCT title_id FROM title_editors WHERE editor_id IN (SELECT editor_id FROM editors WHERE editor_fname = 'Dennis' AND editor_lname = 'McCann') ORDER BY title_id ASC
SQL : How to find number of occurrences without using HAVING or COUNT?
This is a trivial example, but I am trying to understand how to think creatively using SQL. For example, I have the following tables below, and I want to query the names of folks who have three or more questions. How can I do this without using HAVING or COUNT? I wonder if this is possible using JOINS or something similar? FOLKS folkID name ---------- -------------- 01 Bill 02 Joe 03 Amy 04 Mike 05 Chris 06 Elizabeth 07 James 08 Ashley QUESTION folkID questionRating questionDate ---------- ---------- ---------- 01 2 2011-01-22 01 4 2011-01-27 02 4 03 2 2011-01-20 03 4 2011-01-12 03 2 2011-01-30 04 3 2011-01-09 05 3 2011-01-27 05 2 2011-01-22 05 4 06 3 2011-01-15 06 5 2011-01-19 07 5 2011-01-20 08 3 2011-01-02
Using SUM or CASE seems to be cheating to me! I'm not sure if it's possible in your current formulation, but if you add a primary key to the question table (questionid) then the following seems to work: SELECT DISTINCT Folks.folkid, Folks.name FROM ((Folks INNER JOIN Question AS Question_1 ON Folks.folkid = Question_1.folkid) INNER JOIN Question AS Question_2 ON Folks.folkid = Question_2.folkid) INNER JOIN Question AS Question_3 ON Folks.folkid = Question_3.folkid WHERE (((Question_1.questionid) <> [Question_2].[questionid] And (Question_1.questionid) <> [Question_3].[questionid]) AND (Question_2.questionid) <> [Question_3].[questionid]); Sorry, this is in MS Access SQL, but it should translate to any flavour of SQL. Returns: folkid name 3 Amy 5 Chris Update: Just to explain why this works. Each join will return all the question ids asked by that person. The where clauses then leaves only unique rows of question ids. If there are less than three questions asked then there will be no unique rows. For example, Bill: folkid name Question_3.questionid Question_1.questionid Question_2.questionid 1 Bill 1 1 1 1 Bill 1 1 2 1 Bill 1 2 1 1 Bill 1 2 2 1 Bill 2 1 1 1 Bill 2 1 2 1 Bill 2 2 1 1 Bill 2 2 2 There are no rows where all the ids are different. however for Amy: folkid name Question_3.questionid Question_1.questionid Question_2.questionid 3 Amy 4 4 5 3 Amy 4 4 4 3 Amy 4 4 6 3 Amy 4 5 4 3 Amy 4 5 5 3 Amy 4 5 6 3 Amy 4 6 4 3 Amy 4 6 5 3 Amy 4 6 6 3 Amy 5 4 4 3 Amy 5 4 5 3 Amy 5 4 6 3 Amy 5 5 4 3 Amy 5 5 5 3 Amy 5 5 6 3 Amy 5 6 4 3 Amy 5 6 5 3 Amy 5 6 6 3 Amy 6 4 4 3 Amy 6 4 5 3 Amy 6 4 6 3 Amy 6 5 4 3 Amy 6 5 5 3 Amy 6 5 6 3 Amy 6 6 4 3 Amy 6 6 5 3 Amy 6 6 6 There are several rows which have different ids and hence these get returned by the above query.
you can try sum , to replace count. SELECT SUM(CASE WHEN Field_name >=3 THEN field_name ELSE 0 END) FROM tabel_name
SELECT f.* FROM ( SELECT DISTINCT COUNT(*) OVER (PARTITION BY folkID) AS [Count] --count questions for folks ,a.folkID FROM QUESTION AS q ) AS p INNER JOIN FOLKS as f ON f.folkID = q.folkID WHERE p.[Count] > 3

I am attempting to use the following, but this is not working for my time frame limits.
select distinct UID from PtProcTbl
where DT<'20120101'
and NOT EXISTS (Select Distinct UID
where Code in ('99203','99204','99205','99213',
'99214','99215','99244','99245'))
I need to know how to make sure the UID's that I am pulling are the ones don't have a DT after the 1/1/2012 cut off date that contains one of the NOT Exists codes.
The above query returned UID's that actually dates after 1/1/2012 that does contain one of the above codes...
Not sure what I am doing wrong or if I am totally off base on this..
Thanks in advance.
Are you sure you need the NOT EXISTS? How about instead:
AND Code NOT IN ('99203','99204','99205','99213','99214','99215','99244','99245')
