Unwanted Sort
Mar 21, 2006
Hi All,
I am trying to delete rows from a table using a SQL statement similar
to this:
DELETE FROM TableA where ID1 IN
(Select ID1 From TableB where ID2>= @min and ID2<=@max)
Basically I want to delete all rows from TableA that have an ID in a
range in TableB. This is done in a stored proc.
When I look at the execution plan, it is using the indexes as I would
hope for. The problem is that it is doing a sort which accounts for
73% of the cost. I do not need to sort the results. I don't care what
order they are deleted in.
How can I prevent the sort from occuring? I need this delete to occur
as fast as possible.
Thanks In Advance

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

Hi all,
I have a stored procedure that generates the following SQL WHERE clause
UserName LIKE 'Adi234%' AND Fname LIKE 'David%' AND LName LIKE 'Justin%' AND
It is good except that it i can not remove the last AND which is not neccessary at the end of the clause.
I want to remove the last AND that come up at the end, my code places AND after each data field(UserName, Fname, Lname) .
Thanks

I've created an asp.net page that takes the content of text boxes and writes them to a sql table.
The problem is that when I examine the resulting data in the SQL database, I find that the fields written to have had padding added (up to the maximum size of the fields).
I was under the impression that fields of type NVARCHAR did not store padding (only the no of characters being stored).
I've checked it's not the text boxes on the aspx page by explicitly posting values instead of the boxes content and the same thing happens.
Help

Hi ,
I have lot of SQL logins which do not have access to any databases . They do not show any database access when i check their properties .
My server is SQL 7.0 with SP 3 .
I want to clean up those logins with the help of script instead of deleting every login manually which is time consuming as i have to check the database access before deleting the login.
Is there any where script available or any other way to delete these unnecessary logins ? Also will it be a problem on the SQL Server if i delete those logins at one command ?
Any info. will be helpful to me.
Thanks
Sandeep .

Here is a simplified version of my problem:
I am inserting data into a table using a stored procedure. The table has an identity column that increments with each insert. When I use erroneous data in the other fields the insert fails….no surprises there! But when the next insert occurs with valid data I find that my identity field has increased even with those inserts that failed, so my sequence has jumped a few numbers. How do I get the identity inserts to roll back if the rest of the data in a row doesn’t insert successfully?

Hello, I have a report that is based on a dynamic column. The column is specified by the user, and the column tyep may be text, datetime, or bigint. The user specifies the column name, and there is also a parameter that specifies the type. I allow my users to format the date via passing in a date format string, so my code looks something like:
=Switch
(
Parameters!primarycolumntype.Value = "text",
Fields(Parameters!primaryitemcolumn.Value).Value,
Parameters!primarycolumntype.Value = "date",
[DO DATE FUNCTIONS HERE, e.g. Year(Fields(Parameters!primaryitemcolumn.Value).Value)],
Parameters!primarycolumntype.Value = "numeric",
Fields(Parameters!primaryitemcolumn.Value).Value
)
The trouble I am running into is that I am getting invalid date conversion errors whenever a text value is being supplied - in other words, the code in the "DO DATE FUNCTIONS HERE" is being executed regardless of whether my primary column type parameter is text OR date. It would appear that all conversion fuctions are calculated at runtime prior to running other logic. If so, this is a bad thing for me, as that means I cannot mix data types in the same report and figure it out all dynamically. Is this true? I had always thought that the date code (in the example above, the call to Year()) would not be executed unless that statement in the switch statement was true. I've had the same luck with If statements, and Choose statements, and I've even tried using custom code.
I think my whole problem relates to a misunderstanding of how the functions are processed. Can anyone shed some light?
Thanks!
Michael

Hello ,
I have created a publication from SQL Server 7.0 and subscribed the publication it to one of the SQL 2000 server std. edition .
Now there are some entries in the subscription list at the subscriber which need to be deleted .
The list shows the name of the publication , the database name and the date .
I wanted to know hoe can we delete those unwanted entries. If i select the entry and right click on it , there is no delete option .
Are those entries to be deleted from one of the tables at the subscriber or the publisher ? If yes, then what is the name of the table ?
Any ideas ?
Thank you very much .

I have some code that sorts a column logically even if it contains both numbers and text. But I've found that SQL converts certain characters automatically....
Here is the code...
SELECT * FROM TABLE
order by
case when isnumeric(fieldname)=1 then
right(replicate(' ', 10 ) + convert(varchar,convert(numeric(10),fieldname)),10)
else fieldnameend --10 is the length of the field
The issue I've run across is that if my column contains the following strings(5D000,5E000,4E001) it thinks they are numeric then the THEN part of the condition causes a typecasting error....
I found out that any certain combinations of number + E or D + 0. Does anyone know a way to get around this? Try it out select isnumeric('5E0303') will return 1

I wanted to remove an extra transaction log file that was no longer required, and ran the following against the database...
DBCC Shrinkfile (DB_Name_log2, Emptyfile);
go
alter database [Db_Name]
remove file DB_Name_log2;
go
I got a successful removal message. But if I go into the properties of the database, and click on files, it still shows up. Why is this and how can I get rid of it?
It shows up in sys.master_files as offline.

Hi All,
We've got a basic query that pulls a list of some parts out of our inventory database:
SELECT p21_view_inv_mast.item_id, p21_view_inv_mast.item_desc, p21_view_inv_loc.gl_account_no
FROM dbo.p21_view_inv_loc p21_view_inv_loc, dbo.p21_view_inv_mast p21_view_inv_mast
WHERE p21_view_inv_loc.inv_mast_uid = p21_view_inv_mast.inv_mast_uid
This returns a lot of info over three columns: "item_id" "item_desc" and "gl_account_no"
What I want to do is remove any entries where the "gl_account_no" shows as 011500000
I am by no means a TSQL person, I mostly run the canned queries that our vendor gives us so any help with this would be greatly appreciated.

Hi,
I have a need to create a report that has a graph at the top and a table at the bottom. The graph at the top can optionally be made hidden because they cause problems when exported to Excel as images. However, when I set the Hidden property of the graph to true, positions of all items on the report remain absolute. Meaning of course that the table that is located half-way down the page remains half-way down the page and there is a lot of nothing on the first half where the graph used to be.
It would be desirable to have the ability to have the table move up when the graph is not visible, however it obviously doesn't do it automatically and also refuses me the ability to change the position with an expression.
Any advice is appreciated, thank you!

hi
we get ASCII data inserted into a SQL Server database by ODBC connection from an old UNIX system.
Example: INSERT INTO test.db VALUES ('123abc', '456ПРО')
All characters > 128 are converted to "?" automatically.
We tried to setup the database to the appropriate codepage, but we allways get "?" inserted.

I am creating a report query that returns all unreconciled P/O lines. I am near completion but I am unable to find a way to remove the reconciled records.
I have included a script to produce some sample table, data & query.
The recordset dispalys 6 rows. All reconciled Supplier Invoices are duplicated and have transaction codes 40, 50 and reconcile code of 9 (5024, 921689471).
All unreconciled only appear once and have transaction codes 40 and reconcile code of 0 (4835 & 921978016). These are the only records that I want to show.
CREATE TABLE [dbo].[Purch_Ledger](
[EPDIVI] [nvarchar](3) NULL,
[EPSUNO] [nvarchar](10) NULL,
[EPSINO] [nvarchar](24) NULL,
[EPDUDT] [numeric](8, 0) NULL,
[EPTRCD] [numeric](2, 0) NULL,
[code].....
Whatever I try I cant find a way to get rid of the unwanted records.

This a microsoft SQL 2000 server.
I have a DB with mutliple tables that have a column called "Date_stamp", which is used as a primary ID.
Here is my problem:
Some of tables have a bad datetime entry for the "Date_stamp". The bad entry is '2008-3-18". I need to delete this entry from every single table that has a name similary to 'Elect_Sub%Daily'.
I know how to get the user table names from the DB as follows:
SELECT name
FROM dbo.sysobjects
WHERE xtype = 'U' and name like 'Elect_Sub%Daily'
What I need to do is have a query that will basically scroll through the tables name produced by the above query and search and delete the entries that read '2008-3-18".
delete from tableName where Date_Stamp = '2008-3-18'

I have a third party app that passes parameters (main dataset query) from the app to SSRS. Â Unfortunately, when the parameters are passed from the app they will contain equal signs ("=") in front of each parameter. Â For example, the parameters that may be passed to the main dataset query should be:
"HYDRO, OKO, ONEPL, TECHNI"
However, the parameters that are passed from the app, get to SSRS as:
"=HYDRO, =OKO, =ONEPL, =TECHNI"
Again, this is for the main dataset query and there may be one parameter or there may be any number of them.
Basically, I need to strip the "=" signs from the parameters. whether there is one parameter or ten.
I believe that I will need a custom function to strip the equal signs?

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...
Regards,
Lars

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.

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.

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

I'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,
