SQL Server 2012 :: All Permutations Of A Single String
Sep 20, 2015
How to retrieve all possible sets of values from a table, with each set having a unique identifier.
Here's sample data, where any number of rows can be in the "animal" set:
select animal.name
from (
select 'Cat' as name
union all select 'Dog'
union all select 'Bird'
) animalHere's what I'm trying to get:
[Code] ....
It'd be an easy task if I knew how many rows were in the set, but without knowing how many (and being able to do x number of cross joins and CUBE/ROLLUP to produce the list of permutations) or writing a horrid complex of while loops, I'm at a loss.
A single column. All permutations of the values in a single column. Perhaps I should stay off here nearer the end of the day .
I have a problem where I want to write a function to remove recurring characters from a string and replace them with a single same character.
For instance I have the string '12333345566689' and the result should be '12345689'. In Oracle I could do this with "regexp_replace('12333345566689', '(.)1+', '1')", but in T-SQL the only solution I could think of is something like this:
DECLARE @code NVARCHAR(255) SET @code = '12333345566689'; SET @code = REPLACE(REPLACE(REPLACE(@Code, '1', '~1'), '1~', ''), '~1', '1');
and repeat this for 2 - 9. But I'm sure there is a more elegant version for this in SQL Server 2012.
We have some URLs within a bulk block of text some of which are very long. I need to identify rows where such urls exceed say 100 characters in length in amongst other text.So the rule would be return a record if within the string there is a string (without spaces) longer than 100 characters.
You folks always tell me to do as much as I can with set based operations and get rid of those damn cursors, so that is what I would like to do, but I can't really see any way to get around it.
What I have to do is generate all the permutations for 6 values without having any values repeated in each combination (6 factorial, 6x5x4x3x2x1=720 permutations).
Currently I have this job that takes 1-3 seconds to run.

If anybuddy's got any bright ideas on how to retire these cursors, I would love to hear it. Oh ya, AFAIK, the explicit transactions I added don't do a damn thing as far as imrpoving performance.
CREATE Table #Table1 ( ID INT, Name VARCHAR(50), Class VARCHAR(10) ) INSERT INTO #Table1 Select 1, 'name1', 'a' UNION ALL Select 2, 'name1', 'a' UNION ALL
[Code] ....
Is it possible to have each name and its corresponding class in a single line separated by commas to give a result like the one below in #table2 ?
CREATE Table #Table2 ( ID INT, CommaSeparated VARCHAR(100) ) INSERT INTO #Table2 Select 1, 'name1, a' UNION ALL
[Code] ...
What I have
Select * FROM #Table1
Final Result Select * FROM #Table2
Note that I still want to see all the IDs regardless.
If that is not possible to see all the IDs, I think the results below in #Table3 should suffice.
CREATE Table #Table3 ( CommaSeparated VARCHAR(100) ) INSERT INTO #Table3 Select 'name1, a' UNION ALL Select 'name2, b, c, d' UNION ALL Select 'name3, e, f' Select * FROM #Table3
declare @test as varchar(32) declare @test2 as varchar(32)
set @test='today''s problem' set @test2='my <string> '
select @test as '@attribute' for xml path ('myrow') select @test2 as '@attribute' for xml path ('myrow')
I want for xml path to correctly encode the single apostrophe as &apos but the single apostrophe doesn't get encoded. In the second example the greater and less than does get encoded.
have a Prod Server A having TDE enabled on 2 of those databases. I have a Prod Server B having TDE enabled on 3 of those databases. Now I have to create a single Dev server Server C for all the above 5 databases residing on the two servers. So how can I restore all the 5 database backup files on server C.
Does it mean that I need to copy the certificates and Keys from both the Prod server to this Dev Box and then restore the backup files. Once done, I can enable the encryption ON on those 5 database on Dev box or is there any different approach.Also how will tempdb behave in this scenario.
I need to set a variable to datetime and time to exact milliseconds in SQL server in stored procedure.
Example: set MyUniqueNumber = 20071101190708733 ie. MyUniqueNumber contains yyyymmddhhminsecms
Please help, i tried the following: 1. SELECT CURRENT_TIMESTAMP; ////// shows up with - & : , I want single string as in above example.2. select cast(datepart(YYYY,getdate()) as varchar(4))+cast(datepart(mm,getdate()) as char(2))+convert(varchar(2),datepart(dd,getdate()),101 )+cast(datepart(hh,getdate()) as char(2))+cast(datepart(mi,getdate()) as char(2))+cast(datepart(ss,getdate()) as char(2))+cast(datepart(ms,getdate()) as char(4))
This one doesnot display day correctly, it should show 01 but shows 1
I have 2 tables People and Scores. A person might have 1-5 scores (unknown at time of Query). I would like to query the two tables into a results table and if person does not have a record the score will be zero. Scores also have a test number so you know which score it is. I can get it done with Stored Proc but I have to use Temp tables and then put the temp tables together.
People Name ID Tom5 Dick2 Harry3 Larry4 Curly1 Scores PrimaryKeyPeopleIDScoreTestNumber 12801
I have resulting rows from a query similar to the following:
The data is coming from a single table that contains only one coverage code column and one coverage code date, but the end user wants the two coverage code types and dates combined into a single row. So the SELECT looks something like this:
SELECT [Employee ID] = emp.employee_id, [Coverage Code 1] = enr.coverage_code, [Coverage Date 1] = enr.coverage_date, [Coverage Code 2] = case when enr.product_type = 'Accident.Accident' then enr.coverage_code else NULL end,
[Code] ....
I basically want to merge the like Employee ID's together into a single row like the following:
I know I have done this before and it is probably pretty simple.
I have a description field in a table which also stores unit of measure in the same column but with some space between them, I need to split these into two different columns.
1.First i need to update the row if the status column is 0 to 1 2.Need to insert the row IF SegmentId=@SegmentId and SubjectId<>@SubjectId and StaffId=@StaffId 3.Need to insert the row IF StaffId<>@StaffId And ClassId=@ClassId and SegmentId<>@SegmentId and SubjectId<>@SubjectId
I have wrote the stored procedure to do this. But the problem is If do the update. It is reflecting in the database by changing 0 to 1. But it shows error like cannot insert the duplicate
Here is the stored Procedure what i have wrote
ALTER PROCEDURE [dbo].[InsertAssignTeacherToSubjects]
I am trying to insert values in a single table with four columns from 4 different sources. is it possible to run these 4 insertions in parallel. all these insertion are independent of each other
The following works in query if I specify one student (PlanDetailUID) when running query. If I try to specify multiple students (PlanDetailUID) when running query, I get variable cannot take multiple entries. I assume I would need to replace (variables) in PART 2 with (case statements / using select everywhere) to get around the issue or is there a better way ?
I can fetch the counts for total present and absent
Query i have tried is
Declare @StudentId Uniqueidentifier ='0B2D4D41-8D33-4D79-A981-03E0F093F458' Begin select A.StudentId ,A.Date,Count(Date)Total,B.Guid,
[Code] ....
AS result of this query i get the data.Present count and Absent count from date inserted in Dailyattendance tables.
SO my problem is if the student have promoted to next class then by this query it will count the before year also how do i need to calculate the count according to the Class StartDate and Enddate as i mention in the Class Details table what will be the query.
I would like solving the following issue using the Patindex function i cannot retrieve or extract the single numeric value as an example in the the values below i would like retrieve the Value 2, but in my result set the value 22 also appears or it is completely omitted.
how we can replace the multiple values in a single select statement? I have to build the output based on values stored in a table. Please see below the sample input and expected output.
Any better way to query SQL 2012 to display the code of a stored proc to a single line. I'm trying to write a script to insert the contents of the procs between my devestprod environments. So people can query a single table for any proc that is different between environments. At the moment I am using the syscomments view and the text column but the problem here is if you get a lengthy proc it cuts it up into multiple rows.
I can get around it by converting the text to a varchar(max) and outer joining the query, but as you can see by my code below I have to try and guess what the maximum number of rows I'm going to get back for my largest proc. If someone adds a new one that returns 8 rows I'm going to miss it with this query.
I have created a trigger that is set off every time a new item has been added to TableA.The trigger then inserts 4 rows into TableB that contains two columns (item, task type).
Each row will have the same item, but with a different task type.ie.
I've 2 tables QuestionAnswers and ConditionalQuestions and fetching data from them using CTE join and I'm seeing repetitive rows (not duplicate) like, If you have multiple answers for 1 question, the output is like
where london where paris where toronto
why us why japan why indonesia
I want to eliminate the repetitive question and group them as parent child items.
with cte as ( select cq.ConditionalQuestionID from ConditionalQuestions cq inner join QuestionAnswers qa on cq.QuestionID=qa.QuestionID where cq.QuestionID=5 and qa.IsConditional='Y') select distinct q.Question, a.Answer from QuestionAnswers qa inner join Answers a on a.AnswerID = qa.AnswerID inner join Questions q on q.QuestionID = qa.QuestionID inner join cte c on c.ConditionalQuestionID = qa.QuestionID;
Here the SELECT query is fetching the records corresponding to ITEM_DESCRIPTION in 5 separate transactions. How to change the cursor to display the 5 records in at a time in single transactions.
CREATE TABLE #ITEMS (ITEM_ID uniqueidentifier NOT NULL, ITEM_DESCRIPTION VARCHAR(250) NOT NULL)INSERT INTO #ITEMSVALUES(NEWID(), 'This is a wonderful car'),(NEWID(), 'This is a fast bike'),(NEWID(), 'This is a expensive aeroplane'),(NEWID(), 'This is a cheap bicycle'),(NEWID(), 'This is a dream holiday') --- DECLARE @ITEM_ID uniqueidentifier DECLARE ITEM_CURSOR CURSOR
I am creating a query that shows the consumption of stock against Manf Orders (M/O) and struggling on the last hurdle. I am having difficulties calculating a running total based on an Opening Balance. The first line returns the correct results but the following lines do not. I have tried other variants of the "Over Partition" but still no joy?
SELECT CASE WHEN ROWNUMBER > 1 THEN '' ELSE A.Component END AS Component , CASE WHEN ROWNUMBER > 1 THEN '' ELSE A.SKU
I have a string and i want to get only the numbers from right.
For example if I have the string Like '123756zxfggr123456' then it will show me only 123456 or if i have the string like '4vbz67xfggr123dfd' then it will show me only 123 or if i have the string like '123756zxfgg43r5' then it will show me only 5.
I got a function where it gives me all the numbers in a string but I don't need that
CREATE FUNCTION dbo.udf_GetNumeric (@strAlphaNumeric VARCHAR(256)) RETURNS VARCHAR(256) AS BEGIN DECLARE @intAlpha INT
[Code] ....
If I ran the select statement it gives me the result 111123456 but i want only 123456 or if i select
SELECT dbo.udf_GetNumeric('111zxfggr6587fhhfkwee') AS 'Num' it will show me 6587.
I have log files that I am loading into a table with duration data in the format "xx hrs xx min xx sec". Only the parts that are required will be there so if duration is only 2 seconds , the column will show "2 sec".
I am trying to get the duration into in to do some analysis on it and I have come up with this query so far which returns the correct data but i am wondering if there is a way to do what I am trying in a more readable format.
CREATE TABLE #tmp(duration VARCHAR(20))
INSERT INTO #tmp VALUES ('1 hrs 20 min 12 sec'), --4812 sec ('48 sec'), --48 sec ('39 min 1 sec'), --2341 sec ('11 hrs 1 min 1 sec'), --39661 sec ('59 min 0 sec'), --3540 sec ('2 min 50 sec') --170 sec
I need extracting string that is between certain characters that are in certain position.
Here is the DDL:
DROP TABLE [dbo].[StoreNumberTest] CREATE TABLE [dbo].[StoreNumberTest]( [StoreNumber] [varchar](50) NULL, [StoreNumberParsed] [varchar](50) NULL) INSERT INTO [dbo].[StoreNumberTest]
[Code] ....
What I need to accomplish is to extract the string that is between the third and fifth '-' (dash) and insert it into the StoreNumberParsed while eliminating the fourth dash.
Sample output would be:
KY117 CA132 OH174 MD163 FL191
I know that parse, charindex, patindex all might come in play, but not sure how to construct the statement.
I am trying to make a query that will group my errors messages together - my problem is that each of the error messages is unique, due to them having an unique id in them.
