I need to be able to pass a parameter to a stored procedure indicating which column to sort the outcome by. I cannot simply sort it by the passed variable (or I have the syntax wrong...). The sort can be anyone of eight columns and I need to do this in a fair few places on complex SELECT statements, so I am reluctant to use a case statement, which would make the sp rather large.
View 1 RepliesHi,
We got a problem.
supposing we have a table like this:
CREATE TABLE a (
aId int IDENTITY(1,1) NOT NULL,
aName string2 NOT NULL
)
go
ALTER TABLE a ADD
CONSTRAINT PK_a PRIMARY KEY CLUSTERED (aId)
go
insert into a values ('bank of abcde');
insert into a values ('bank of abcde');
...
... (20 times)
select top 5 * from a order by aName
Result is:
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
select top 10 * from a order by aName
Result is:
11Bank of abcde
10Bank of abcde
9Bank of abcde
8Bank of abcde
7Bank of abcde
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
According to this result, user see the first 5 records with id 6, 5, 4, 3, 2 in page 1, but when he tries to view page 2, he still see the records with id 6, 5, 4, 3, 2. This is not correct for users. :eek:
Of course we can add order by aid also, but there are tons of sqls like this, we can't update our application in one shot.
So I ask for your advice here, is there any settings can tell the db use default sort order when the order by column value are the same? Or is there any other solution to resolve this problem in one shot?

Does anyone know how to change column order of a table with data.
View 6 Replies View RelatedTo order a recordset I can simply do
"Select * From Table Order by ColumnName;"
But my need is different.
In a column I have the following content:
"C"
"P"
"F"
"A"
But "F" and "A" may exist more than once.
I must order the recordset always in the order
"C"
"P"
"F"
"A"
and not "A", "C", "F", "P".
Can anyone pls help me?
Thanks in advance.
Does column order really matter for Query Optimizer to pick index.Case 1: Say my CUSTOMER table has one composite index containing FirstName and LastName. FirstName exists prior than LastName. Does the column, FirstName and LastName, order matter to have Query Optimizer to utilize the index when I write WHERE clause in a SELECT statement?Statement 1:SELECT * FROM CUSTOMER WHERE FirstName = 'John' and LastName ='Smith'Statement 2:SELECT * FROM CUSTOMER WHERE LastName ='Smith' and FirstName = 'John' Will both statement 1 and 2 use the composite index or only statement 1?Case 2:Say my CUSTOMER has two single-column indexes. One index is on column FirstName. Another is on column LastName.For statement 1 and 2 above, which index will be picked by Query Optimizer or both? How does QO pick for index?I read couple book and some books say column order matter but some say no. Which one should I go with? I'm kind of confused.
View 2 Replies View RelatedI'm using SQL Server 2005 and are having some troubble with sorting a paged result set. I'm using the OVER Clause to achieve the sorting and paging and have the following query:1 WITH ProjectList AS

This works fine, and give me the results i want. The problem occurs when I want to sort by "NumberOfUsers" which is the results of a sub query.When i say "ORDER BY NumberOfUsers" instead of Id on line 8, I get the following error:
Msg 207, Level 16, State 1, Line 10Invalid column name 'NumberOfUsers'.
I read this in the documentation:
When used in the context of a ranking window function, <ORDER BY Clause> can only refer to columns made available by the FROM clause. An integer cannot be specified to represent the position of the name or alias of a column in the select list. <ORDER BY Clause> cannot be used with aggregate window functions.
So this means that what I'm trying to do is not possible. How can I then sort by NumberOfUsers? Is there any other way to achieve this

Hi, I am writing a small search engine.
There are two tables. The first one holds the search engine main index, the second one is link table.
I have the following query that retrieves results. I would like to sort the results by:
dbo.OCCURS2(LOWER(:query),se_links.anchor). se_links.anchor obviously comes from se_links table, so I get an error. Is it possible to done in one query?
I'm using MSSQL 2005. Thanks.
PS. Function OCCURS2 returns number of occurrences of one string in other.
Code:
select
id as Id,
uri as ElementUri,
size as Size,
modified_date as ModifiedDate,
title as Title,
text as Text,
dbo.OCCURS2(LOWER(:query),Title) as TitleOcc,
dbo.OCCURS2(LOWER(:query),Text) as BodyOcc
FROM se_index
WHERE (title LIKE :query) OR
(text LIKE :query) OR
(id IN
(SELECT se_links.target_index_id
FROM se_links INNER JOIN
se_index AS se_index_1 ON
se_links.target_index_id = se_index_1.id AND
se_links.anchor LIKE :query))

Is there a shortcut to spelling out column names when you are doing a select statement?
For instance could you write Select 1, 5, 6 from table where whatever...
I tried this but didn't get any results so if you can I must be using wrong syntax.
Thanks

We are using partitioned unique indexes on partitioned tables. When the Unique Index is built, should the column the index is partitioned by be the top (leftmost) column in the index? While this violates cardinality, it makes sense (at least to me) that the first thing the query execution would do is figure out which partition(s) contain the result set, then filter from there.
What do you guys think? Is there any documentation on optimizing partitioned indexes?

Because the "-" means "continues", it the thing is still activated, so if it makes it easier, i could put the today's year afterwards during the query, if it ends with a - ...
Now, simply doing a
SELECT * FROM [table] ORDER BY TIME;
Sorts it "perfectly", apart from the "2002-" is just placed before 2005 and after 2001.
So, of course, it fails on all entries with a leading "-" ...
Right when I clicked "submit", of course, I can simply replace all entries with a time ending with "-", with the todays Year, so at least they will get at the end of the query...
Well, have to do a union, first sorting all without the "-", then sorting all with the "-", and that should be it...
