Is there any way to sort your results in a way that the empty results comes last? When I sort my recordset on a certain column I first get the empty values and the A, B, C etc. I would like to have it A, B, C, ..., Empty ones.

I 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
i encounter this error..
Cannot sort a row of size 8107, which is greater than the allowable maximum
of 8094.?
why this error occur? can someone explain? how to avoid this? thanks!!
We 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...

I'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!

SQL Server 2000 SP4. Hoping to find a logical explanation for a certainbehavior.Consider this script:USE pubsGOIF 1 = ALL (SELECT contract FROM dbo.authors WHERE state = 'CA')PRINT 'TRUE'ELSEPRINT 'FALSE'This, as expected, prints FALSE, since not all authors in CA are undercontract. Now, if the script is changed as follows:USE pubsGOIF 1 = ALL (SELECT contract FROM dbo.authors WHERE state = '')PRINT 'TRUE'ELSEPRINT 'FALSE'then the result is TRUE. In other words, the expression evaluates to TRUEwhen the select statement produces an empty set, which doesn't make senseto me. Even more interesting, the expressionNULL = ALL (SELECT contract FROM dbo.authors WHERE state = '')still evaluates to TRUE (ANSI_NULLS is ON).Can anyone explain these results? Is this the expected behavior in the SQLstandard, or something that is specific to SQL Server? Thanks.--remove a 9 to reply by email

I have: 4 tables and 1 table variable.
CCenters (ID, Name)
Campaigns (ID, Name)
Rel (ID, CCenterID, CampaignID) - [many to many]
and @SCampaigns (ID, CampaignID) - represents the selected campaigns by the user
performing the commands below I would get the centers associated with the campaigns selected.SELECT CCenterID
FROM Rel
INNER JOIN @Campaigns ON @SCampaigns.CampaignID = Rel.CampaignID
But what I really want are the common centers to the selected campaigns.
Thanks

When 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

We have a vendor who insists that sql server 7 be set to a binary sort order. Is there any real advantage to this as opposed to a dictionary sort?

HOW CAN I CHECK THE SORT ORDER OF MY OLD SERVER?

Is there a query you can run against a 7.0 server to return the chracter set and sort order.
View 1 Replies View RelatedI'm trying to setup a duplicate of an old SQL Server 4.2 server to put in place while we upgrade the server, but I can't get the sort-order right. I know the existing server uses sort order id 40, but I can't find which sort-order that corresponds to during the install process. If anyone can give me a system table that lists all the sort orders names and id's, or can tell me what the text name for sort order 40 is, I would be very grateful.
Thanks,

Hi 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
Atlanta Cookie2 20
Atlanta NULL 50
Dallas Cookie1 80
Dallas Cookie2 40
Dallas NULL 120
NULL NULL 100
Thanks,

I need to copy the structure and data of an existing SQL 6.5 server to one with a different 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.

Hi There i have two windows 2000 servers which are both running SQL and i would like to restore a backup from one server to the other. Which in my opinion should be an easy task but when i go into the restore option and point it at the file i would like to restore i get the follwoing error
"The database you are attempting to restore was backed up under a different sort order ID (52) than the one you are currently using on this server (50) and at least one of them is a non binary sort order. Backup or restore operation operation terminating abnormally."
The server that i am trying to restore to already has databases on this so i cannot just reinstall SQL and change the sort order not that id know how to do that but this is what i have read.
Is htere anyway that i can put insome script for the database to fix this ???
Im using Enterprise manager with SQL server 7
Thanks in advance
