SubQuery In Both SELECT And WHERE Part. How To Optimise?
Apr 11, 2008
Ok I have the following SQL, I have a subquery in the SELECT part but also the same subquery in the WHERE part as well.
What I'm trying to do is get all parents that have children OR get all parents with no children OR just get all parents regardless (@HasResponses is a BIT that can be 1, 0 or null). At the same time I want to count the total number of children in the select list, but I'm having to copy the same subquery in the SELECT and WHERE parts which doesn't seem terribly optimal to me (maybe it is, that's why I'm asking). I've tried referencing the column alias in the select list (AS [Responses]) for the where part (@HasResponses = 0 AND [Responses] = 0), but it doesn't seem to work.
Is this the most optimal way to do it? Is there a better way? I'm working with SQL Server 2005.
SELECT
f.FeedbackText AS [Feedback Comment],
u.Name AS [Feedback Author],
f.CreatedDate AS [Created On],
(
SELECT COUNT(*)
FROM FeedbackResponse fr
WHERE fr.FeedbackID = f.ID
) AS [Responses]
FROM Feedback f
INNER JOIN [User] u ON f.StaffID = u.StaffID
WHERE f.CreatedDate >= @DateFrom
AND f.CreatedDate <= @DateTo
AND
(
@HasResponses IS NULL
OR
(
@HasResponses = 1 AND
(
SELECT COUNT(*)
FROM FeedbackResponse fr
WHERE fr.FeedbackID = f.ID
) > 0
)
OR
(
@HasResponses = 0 AND
(
SELECT COUNT(*)
FROM FeedbackResponse fr
WHERE fr.FeedbackID = f.ID
) = 0
)
)

I have two tables. Customers and Orders. Customers table contains customer id, and customer name columns. Orders table contain order id,product id,customer id. So orders table contains products bought for each order by a customer.
I want to write a query to retrieve all order details (products for each order and customer id), where product with id 5 is bought. Can I write this sql without using a subquery.
Hi.I'm new in SqlServer programing.Is it possible to do something like this ( It is common construction in oracle )Select X from(select a+1 as X from tab1)without creating view containig subquery ?thx. MD

hi all how are you today i am not good because i can't set this variable in this query please read this thanks
create table aaa1 (id_no int, name varchar(20)) go create table aaa2 (id_no int, name varchar(20)) go
insert into aaa1 values (1,'rahmi') insert into aaa1 values (2,'atilganer') insert into aaa1 values (3,'hasan')
insert into aaa2 values (4,'rahmi') insert into aaa2 values (5,'atilganer') insert into aaa2 values (6,'hasan')
/* declaring any numeric variable*/ declare @id_no_var int /* and set variable to max table name's (aaa2 table in this example) id_ no column
note :insqlhelp and insqlhelp2 is an alias for tablename query (recommended from sql help */
set @id_no_var = (select max(id_no) from (select max(name) insqlhelp from sysobjects where name like 'aa%') insqlhelp2 )
this query return:
Server: Msg 207, Level 16, State 3, Line 3 Invalid column name 'id_no'.
this error returned because max(id_no) column is absent
if you are run select * from (select max(name) insqlhelp from sysobjects where name like 'aa%') insqlhelp2
this query return that
insqlhelp --------------- aaa2
(1 row(s) affected)
this mean that my table name query returned table name but i cant use this name in any other query (i think because of daclaring alias "insqlhelp, insqlhelp2")
other way is
set to any other text variable to table name, and concetanate to query, and execute with exec
table1 member_name legacy_id team_name ----------------------------------------- Bill 1234 nationals Bill 1234 nationals Tom 3456 nationals Tom 3456 orioles
I wish I could restructure the data or normalize it but this is unfortunately what I have to deal with.
I need a query that returns the team name and the number of times it appears in the table excluding duplicates for each person. I have duplicates all over the place in this tables. Bill could have nationals listed a couple hundred times.
My query should return
team_name count ----------------- nationals 2 - because it occurs for bill, and tom orioles 1 - because it occurs for tom
If I do something like:
select distinct(team_name), count(team_name) from table1 group by team_name
I get back:
team_name count ------------------- nationals 3 - because it occurs for bill twice, and tom once orioles 1 - because it occurs for tom once
I've tried something like:
select team_name, count(team_name) from table1 where legacy_id in ( select distinct legacy_id from table1 )
I get a syntax error. Regardless, I'm not sure this will give me what I need.
I've tried over a dozen variations of select distinct, joins, etc but with no luck.
Any of you sql gurus know how to solve this problem? I've been banging my head against it for a couple days and boy does my head hurt.
SELECT Field1, (SELECT Field2 FROM Table2 WHERE Key=1) AS Field2 FROM Table1 SELECT Field1, (SELECT Count(Field2) FROM Table2 ) AS Field2 FROM Table1
But when I try execute it with SQL Server Everywhere it says "Token in error = SELECT".
Is there some kind of limitations to do this with SQL Everywhere? SQL Everywhere seems to be nice compared with Access and JET but for my project it's useless if I can't use subquerys.
I have 2 tables, Jobs and Categories.Each job belongs to a category. At present, I am returning all categories as follows:SELECT categoryID, categoryName FROM TCCI_CategoriesWhat I'm trying to do, is also return the number of jobs assigned to each category, so in my web page display, it would show something like this:Engineering(5)Mechanical(10) etc.My db currently has 5 categories, with only one job assigned to a category. I tried the following sub-query, but instead of returning all the categories with their job counts, it just returns the category that has a job assigned to it:SELECT c.categoryID, c.categoryName, COUNT(j.jobID)FROM TCCI_Categories c, (SELECT jobID, categoryID FROM TCCI_Jobs) jWHERE j.categoryID = c.categoryIDGROUP BY c.categoryID, c.categoryName, j.jobIDThis is the output when I run the query:categoryID categoryName Column1 ---------------- ---------------------- ------------------------------32 Engineering 1 How would I fix this?
Hi.I have an insert query which inserts record that are returned from a select subquery: INSERT tbl1 (col1,col2,col3) SELECT (col1,col2,col3) FROM tbl2 WHERE... col1 and col2 in tbl1 combined ,are a unique index. So, as I understand it sql server first returns all the records from tbl2 and then starts to insert them one by one into tbl1. The problem is, that if one of the records returned from tbl2 violates the unique keys constraint in tbl1, sql server will not insert all of the records (even those which maintain the key constraint).How can I solve this ?
I am pulling back records from the DB in this case to get Wheel information. I am pulling back based on user input, but also need to query a second table that contains the Price and model number from another table based on a field being pulled back in the original select.
I am not sure if this makes sense, here is a working copy of the SQL I have , but it's not pretty. There must be another way of stating this statement that i am missing, can anyone give me some suggestiosn?
SELECT tblMacPak2.*, (SELECT ListPrice FROM tblMacPakPrices WHERE WheelId = OEMWheel) AS ListPrice, (SELECT PartNumber FROM tblMacPakPrices WHERE WheelId = OEMWheel) AS PartNumber FROM tblMacPak2 WHERE (Make = N'honda') AND (Model = N'civic') AND (SubModel = N'standard') AND (YearRange = N'2006') AND (Factory_Wheel_Diameter = N'15')
Hi. I have an insert query which inserts record that are rturned from a select subquery:
INSERT tbl1 (col1,col2,col3) SELECT (col1,col2,col3) FROM tbl2 WHERE...
col1 and col2 in tbl1 combined ,are a unique index.
So, as I understand it sql server first returns all the records from tbl2 and then starts to insert them one by one into tbl1.
The problem is, that if one of the records returned from tbl2 violates the unique keys constraint in tbl1, sql server will not insert all of the records (even those which maintain the key constraint). How can I solve this ?
I know this is an easy one and I know I've read it somewhere, but I can't seem to write the correct format to run correctly. I am trying to build a SELECT statement base on the selected values of a dropdown list on a webform. The selected values will be part of the Table name.. ("client_info" & location_option.selecteditem.value) Can someone show me the correct syntax for adding a form variable into a SELECT statement? Thanks
ALTER PROCEDURE [dbo].[sp_SelectMostRecentArticle]

END GO
as you can see, im trying to return a comment_count value, but the only way I can do this is by defining the variable.
I have had to do it this way, because I cannot say COUNT(comment.comment_id) AS comment_count or it returns an error that it cant reference the comment.comment_id.
But when change it to FROM article, comment; I get errors about the article_author_id and article_comment_id.
And i cant add a join, because it would return the amount of rows of the comment...
unless someone could help with what i Just decribed (as i would prefer to do it this way), how would i return the variable value as part of the select statement?
I have an xml stored in a coulum of a table and I use the following query to extract an xml element :
select CONVERT(XML,CONVERT(NVARCHAR(max),Response)).value('(/Quote/error)[1]','nvarchar(max)') as Excepiton .The result of the expression is :
TL43:The product has no marked price.;I would like to select only the code : TL43and then separately I would like to select The product has no marked price.Is there a way I can do it?
Hi there, I need to select rows from a table, but include the top 3 rows of another linked table as a single field in the results. Here is my basic structure:
I'm trying to select from a table with three columns. I want these columns to be spread out among multiple columns based on the values. I hope someone can shed some light on this. I might be able to use pivot, but don't know how the syntax would roll for this.
Here is the example of dummy values and the output I am trying to obtain.
drop table table1
create table table1
(Category int, Place int, Value int)
insert into table1 values
(1, 1, 20)
insert into table1 values
(1,2, 12)
insert into table1 values
(1,3, 30)
insert into table1 values
(2,1, 34)
insert into table1 values
(2,2, 15)
insert into table1 values
(2,3, 78)
select Category,
(select top 1 value from table1 where place = 1 and Category = t1.Category) as place1,
(select top 1 value from table1 where place = 2 and Category = t1.Category) as place2,
(select top 1 value from table1 where place = 3 and Category = t1.Category) as place3
I have a query where I need to select a bunch of rows from one table, hypothetically we'll call them ssn, first name, last name, and I need to select a subquery which coalesces a bunch of rows together (in no case will there be only one row returned from that subquery).
Anyone know how I could go about this? I'll give you an example of what I've tried, but it does not work currently.
delcare @path varchar(255) select e.ssn,
e.firstname, e.lastname, ( @path = select coalesce(@path + ', ', '') from space s1 inner join space s2
on s1.lft BETWEEN s2.lft AND s2.rgt and s1.rgt BETWEEN s2.lft AND s2.rgt where s1.spaceID = 133225 select @path) from employees e where e.id = 5
Using that spaceID is guaranteed to give me four rows, and I need them coalesced together, but I can't just use a function (too slow on the scale it would be used), any thoughts?
I have a query that returns results based on information in several tables. The problem I am having is that is there are no records in the one table it doesn't return any information at all. This table may not have any information initially for the employees so I need to show results whether or not there is anything in this one table. Here is my select statement: SELECT employee.emp_id, DATEDIFF(mm, employee.emp_begin_accrual, GETDATE()) * employee.emp_accrual_rate - (SELECT SUM(request_duration) AS daystaken FROM request) AS daysleft, employee.emp_lname + ', ' + employee.emp_fname + ' ' + employee.emp_minitial + '.' AS emp_name, department.department_name, location.location_name FROM employee INNER JOIN request AS request_1 ON employee.emp_id = request_1.emp_id INNER JOIN department ON employee.emp_department = department.department_id INNER JOIN location ON department.department_location = location.location_id GROUP BY employee.emp_id, employee.emp_begin_accrual, employee.emp_accrual_rate, employee.emp_fname, employee.emp_minitial, employee.emp_lname, department.department_name, location.location_name ORDER BY location.location_name, department.department_name, employee.emp_lname
The section below is the part that may or may not contain information: SELECT (SELECT SUM(request_duration) AS daystaken FROM request) AS daysleft
So I need it to return results whether this sub query has results or not. Any help would be greatly appreciated!!! TIA
Hello All, I have a query that I could use some help with. I would like to see how I could make this query more optimised. I am not hte best at Joins so if someone could help me with this that would be great. Right now its taking about 24-30 secs to run which is a no go. Im wondering if some kind of join would work better? thank you much -jes

hi, I want to know how to optimise this query, the results almost reach 6000 rows, I want to speed this query.
condition2=Select Distinct A,B,B+C+D,E,F,G From a.table where condition1 order by A,B,B+C+D,E,F,G Select Sum(amount) From b.table where condition2 And date=datetime.
I use this piece of code in a trigger to check if new entered row has unique order number in the given year:
IF EXISTS
(
SELECT COUNT(*)
FROM SPD_Orders
GROUP BY ORD_Year, ORD_Number
HAVING COUNT(*) <> 1
)
RAISERROR('Order with this No exists in given year, 11, 1)
but this code causes deadlocks in my database.
Any suggestions how can I change it to avoid these deadlock? 1. Some constrain? If yes, so how to write it? 2. Index like to enable query optimiser to change execution plan?
CREATE NONCLUSTERED INDEX [_dta_index_SPD_Orders_10_1429580131__K8_K7] ON [dbo].[SPD_Orders]
(
[ORD_Year] ASC,
[ORD_Number] ASC
3. Same index as above but unique and then I will not have to use this trigger, cause database itself with return an error? 4. Any other, the best solution ?
