Sort By Occurence
Mar 29, 2001When sorting records in a table how do you sort by the occurence of a field.
So, if the table contained: 1,1,2,2,2,3,3 how would you get it to sort using the desc syntax to give 2,2,2,3,3,1,1

Is there a function in SQL that will return the number of occurence of 1 string to the other.
e.g.
string1 = "1"
string2 = "2131145"
function should return 3
How do i obtain this in SQL?
Thanks in advance

View 4 Replies View RelatedStrange Occurence In SP4 On Sql Server 2000
Aug 7, 2007We have a strange occurrence in one of our dev Sql server. Our platform is Sql Server 2000 on SP4. Build Number is 8.00.2039
TableA
Sid int, --Non-Clustered Index
Aid int,
Uid int,
€¦..
TableB
Iid int,
Sid int, ---No foreign key constraint to TableA.Sid but logically refers to that column. --Non-Clustered Index
€¦..
Now, we are working on schema changes, now TableB looks like
TableB
Iid int,
Uid int, ---Logically refers to TableA.Uid
€¦..
Sid in TableB is dropped and a new column Uid is added.
And there is no Sid in TableB.
We have an existing SP that refers to TableB.Sid like
Create proc sp_ab
As
Select Uid from TableA where Sid = (Select Sid from TableB where Iid = @Iid)
After making the schema changes listed above, if I try to compile this SP without making any changes to the procedure, it should fail. Surprisingly it passes compilation and also retrieves data using hash joins and doing table scans on TableA avoiding index seeks. This SP used to take less than second, now takes almost 90 seconds to retrieve data. I couldn't replicate this problem with another set of objects.
If I make changes to the SP sp_ab like
Create proc sp_ab
As
Select Uid from TableA where Uid = (Select Uid from TableB where Iid = @Iid), it runs less than a second as it should.
Whats surprising is, if I do 'Select Sid from TableB where Iid = 1 ' in Query analyzer, it throws error referring to invalid column Sid in TableB but couldn't throw this error when the sql is wrapped in a SP. Everything else in the DB and in the db server seems to be ok except this.
If I query Syscolumns table, I couldn't see any references to Sid in TableB after the schema chnages and not sure why the code in SP is not caught during compilation. Any clues.
Check The First Occurence Of A Numeric In A String
Mar 17, 2008
Hi All,
I want to extract a numeric value from a string. Example, in a string like - Mgmt Pack: Processor Exception Threshold >80% Every 10 Minutes. - I want to extract that number 80. Since, later I'll want this number to plot a graph.
Since this is going to be an alert pulled from OnePoint (MOM Operational Database), the number will vary, and so I cannot look for the same number. So, can anyone help me how to get this working?
Thanks a lot in advance and let me know if the question is not clear.

Finding The Character Position Of Nth Occurence In A String.
Jun 15, 2001Hi Friends:
I usually run this query in Oracle to find out the position of a character in a string from first position to the nth occurence.
For example, I run the following queries in oracle to get the desire result.
SQL> select instr('DADADAQQQA','A',1,1) FROM DUAL;
INSTR('DADADAQQQA','A',1,1) -- First occurence of 'A' from start.
---------------------------
2
SQL> select instr('DADADAQQQA','A',1,2) FROM DUAL;
INSTR('DADADAQQQA','A',1,2) -- Second occurence of 'A' from start.
---------------------------
4
SQL> select instr('DADADAQQQA','A',1,3) FROM DUAL;
INSTR('DADADAQQQA','A',1,3) -- Third occurence of 'A' from start.
---------------------------
6
SQL> select instr('DADADAQQQA','A',1,4) FROM DUAL;
INSTR('DADADAQQQA','A',1,4) -- Forth occurence of 'A' from start.
---------------------------

Dynamic Sort Column And Sort Order Not Working
Aug 7, 2007I am trying to set sorting up on a DataGrid in ASP.NET 2.0. I have it working so that when you click on the column header, it sorts by that column, what I would like to do is set it up so that when you click the column header again it sorts on that field again, but in the opposite direction. I have it working using the following code in the stored procedure: CASE WHEN @SortColumn = 'Field1' AND @SortOrder = 'DESC' THEN Convert(sql_variant, FileName) end DESC,
case when @SortColumn = 'Field1' AND @SortOrder = 'ASC' then Convert(sql_variant, FileName) end ASC,
case WHEN @SortColumn = 'Field2' and @SortOrder = 'DESC' THEN CONVERT(sql_variant, Convert(varchar(8000), FileDesc)) end DESC,
case when @SortColumn = 'Field2' and @SortOrder = 'ASC' then convert(sql_variant, convert(varchar(8000), FileDesc)) end ASC,
case when @SortColumn = 'VersionNotes' and @SortOrder = 'DESC' then convert(sql_variant, convert(varchar(8000), VersionNotes)) end DESC,
case when @SortColumn = 'VersionNotes' and @SortOrder = 'ASC' then convert(sql_variant, convert(varchar(8000), VersionNotes)) end ASC,
case WHEN @SortColumn = 'FileDataID' and @SortOrder = 'DESC' THEN CONVERT(sql_variant, FileDataID) end DESC,
case WHEN @SortColumn = 'FileDataID' and @SortOrder = 'ASC' THEN CONVERT(sql_variant, FileDataID) end ASC And I gotta tell you, that is ugly code, in my opinion. What I am trying to do is something like this: case when @SortColumn = 'Field1' then FileName end,
case when @SortColumn = 'FileDataID' then FileDataID end,
case when @SortColumn = 'Field2' then FileDesc
when @SortColumn = 'VersionNotes' then VersionNotes
end
case when @SortOrder = 'DESC' then DESC
when @SortOrder = 'ASC' then ASC
end and it's not working at all, i get an error saying: Incorrect syntax near the keyword 'case' when i put a comma after the end on line 5 i get: Incorrect syntax near the keyword 'DESC' What am I missing here? Thanks in advance for any help -Madrak

To Sort Or Not To Sort
Dec 10, 2007We are using a modeling technique called Anchor Modeling in our data warehouses. You can read more about the technique itself at our homepage http://www.intellibis.se, where we have published a fact sheet and a recently held presentation (TDWI European conference). One of the features with this technique is its simple way to historize data. This is done by having a fromDate column which together with the surrogate key will yield a unique combination. On the tables that has this kind of historization we add a primary key, which in turn will create a clustered index, with the following specification (surrogateKey asc, fromDate desc). This will physically order data on the storage media according to the specificed columns and ordering. Now I move on to create a "latest view" of this table which does a subselect to find the latest version for every surrogateKey using max(fromDate). Should not the optimizer now figure out that data is ordered so that the latest version always comes first for every surrogateKey, hence any sorting would be unneccessary? If I look at the actual execution plan after running a query that uses the view there is a sort in the plan, but the cost is always 0%. Does this mean that it did not sort the data, or that it did call a sorting routine, but it actually took very little time to do the sorting? If so, is there a reason that is has to do the sorting or could it have been left out by an even smarter optimizer?
I would also like to applaud the people behind the optimizer, since it will figure out which tables are in fact necessary to query and eliminate others, even if I have left joined them into the view I am using. This speeds up performance and makes anchor modeling feasible. Unfortunately optimizers from other vendors seem to have trouble doing this...
Regards,
Lars
SQL Sort Help
Mar 11, 2008I've been racking my brain all day and I finally decided to ask for help. I've got two tables with rows from the first that need to be sorted by the second. The problem is that the rows don't always exist in the second table. I've tried various forms of INNER, LEFT, RIGHT, OUTER, LEFT OUTER, CROSS, etc., etc., etc. and nothing (oh yeah UNION too). Every time I get close, I lose the records that don't have matches.
Something close-
SELECT A.IDDoc, B.First
FROM A
LEFT JOIN B
ON A.IDDoc = B.IDDoc
WHERE B.Dept = 'A'
ORDER BY B.First
Example Data
Table A
IDDoc Document
---------------------------
1 1467.doc
2 8722.doc
3 A47F.doc
4 88DQ.doc
5 ABCD.doc
Table B
IDDoc Dept First
----------------------------
1 A John
2 A Bob
3 A Ralph
4 A Diane
Results I Want
IDDoc First
-------------------
5 NULL
2 Bob
4 Diane
1 John
3 Ralph
Any help is appreciated. If I've posted in the wrong forum, please feel free to direct me to a better one.
Thanks in advance!

How To Sort NULLs?
Jul 13, 2004Hi All,
I have a table with 3 columns. Product, Location and Value. The data looks like this:
NULL NULL 100
Atlanta NULL 50
Atlanta Cookie1 30
Atlanta Cookie2 20
Dallas NULL 120
Dallas Cookie1 80
Dallas Cookie2 40
This table gets filled with a Groupby with Rollup option. The NULLS show subtotals/total. Is there a way to build a query that returns the results with NULLs at the bottom of each section like:
Atlanta Cookie1 30

BCP And Sort Order

Normally, I would use the transfer tool to accomplish this, but the servers are on different networks. My question is, is BCP the answer? In other words, will the data copied via BCP from the sending server be able to be copied on the recieiving server. Also, is there a way to automatically generate the BCP statements for all tables? What I would really like is to be able to get at the scripts and data files created by the transfer tool.
