How SELECT In WHERE Clause Works?

Jun 8, 2008

Please help 

I'm trying to do a select command but doesn't return any record

I have two tables one is "lists" another one is "list_records"

in the liss table I have 4 records and in the list_records I have only one record which is tell who is already visited the site so I created a query to get people who is NOT visited the site

 

Here is my query (I got 0 record return) 

 

SELECT *FROM lists

list_reccords

WHERE NOT EXISTS (SELECT *

                                                   FROM lists,

                                                      list_records                                       WHERE list_records.is_visited = 1

                                             AND lists.list_id = list_records.list_id)

Is It Possible To Re-reference A Column Alias From A Select Clause In Another Column Of The Same Select Clause?

Jul 20, 2005

Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

Hi

The query below with table join works on my dev server sql server MC
v2, but returns only NULL values for Questiona and Module on the live

like relationships?

SELECT

Expression Defined In SELECT Clause Overwrites Column Defined In FROM Clause

May 14, 2008

2 examples:

1) Rows ordered using textual id rather than numeric id


Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id






Result set is ordered as: 1, 11, 2
I expect: 1,2,11


if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.

2) SQL server reject query below with next message

Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.




Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id




Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.

It reproducible on

Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)


and


Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)

In both cases database collation is SQL_Latin1_General_CP1251_CS_AS

If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.

Could someone clarify - is it bug or expected behaviour?

SELECT Then DELETE Versus Extra Clause In SELECT

Nov 29, 2007

Far below (in section "original 3 steps"), you see the following:1. a temp table is created2. some data is inserted into this table3. some of the inserted data is removed based on a join with the sametable that the original select was made fromIn my opinion, there is no way that the join could produce more rowsthan were originally retrieved from viewD. Hence, we could get rid ofthe DELETE step by simply changing the query to be:INSERT INTO #details ( rec_id, orig_corr, bene_corr )SELECT rec_id, 0, 0FROM viewDWHERE SOURCE_SYS NOT IN ( 'G', 'K' )AND MONTH( VALUE_DATE_A8 ) = MONTH( @date )AND YEAR( VALUE_DATE_A8 ) = YEAR( @date )AND INMESS NOT LIKE '2__' ---- the added line===== original 3 steps (mentioned above) =====CREATE TABLE #details (rec_id UNIQUEIDENTIFIER PRIMARY KEY NOT NULL,orig VARCHAR(35) NULL,bene VARCHAR(35) NULL,orig_corr TINYINT NULL,bene_corr TINYINT NULL)INSERT INTO #details ( rec_id, orig_corr, bene_corr )SELECT rec_id, 0, 0FROM viewDWHERE SOURCE_SYS NOT IN ( 'G', 'K' )AND MONTH( VALUE_DATE_A8 ) = MONTH( @date )AND YEAR( VALUE_DATE_A8 ) = YEAR( @date )DELETE dFROM #details dJOIN viewD v ON ( d.rec_id = v.rec_id )WHERE INMESS LIKE '2__'

Complex SQL Select Statement That Works But...

Jul 24, 2006

I have a pretty complex SQL statement that looks like this:
SELECT     aspnet_Employers.active, aspnet_Employers.accountexecutiveusername, aspnet_Employers.created, aspnet_Employers.Title AS Contact,                       SUM(aspnet_Employers.EmployeeCount) AS [# Emps], COUNT(aspnet_Signups.account) AS [# Email Addresses], COUNT(aspnet_ContactMe.username)                       AS [# Contact Me], COUNT(aspnet_AppsSubmitted.account) AS [# Apply Now]FROM         aspnet_Employers LEFT OUTER JOIN                      aspnet_AppsSubmitted ON aspnet_Employers.UserName = aspnet_AppsSubmitted.account LEFT OUTER JOIN                      aspnet_ContactMe ON aspnet_Employers.UserName = aspnet_ContactMe.username LEFT OUTER JOIN                      aspnet_Signups ON aspnet_Employers.UserName = aspnet_Signups.accountGROUP BY aspnet_Employers.accountexecutiveusername, aspnet_Employers.created, aspnet_Employers.Title, aspnet_Employers.active
It does work the way i want it, but the problem is, on my Gridview when i change the Employers accounts "Active" status either way, it changes the username field from the username of the account, to "null".
Why does it do this?
What would i change to prevent this from happening?

Select Statement Works In 2000 But Not In 2005

Jan 2, 2008

I hope this is a easy one. We are trying to find a fix for a select statement that works in 2000 but not in 2005 with a simple select statement.

The easiest statement that will duplicate the error is:

TestTable has 3 columns: Primary, strTest, strTest2



SELECT strTest, strTest AS Name
FROM TestTable
ORDER BY strTest2



If you sort by the Primary column you will not receive an error.

How can you select the same column twice and then sort in the SQL statement?

Help: Why IN-Operator With Select-Statement It Doesn't Work? But With Given Values It Works

Jun 4, 2007

Hello to all,
i have a problem with IN-Operator. I cann't resolve it. I hope that somebody can help me.
I have a IN_Operator sql query like this, this sql query can work. it means that i can get a result 3418:
declare @IDM int;
declare @IDO varchar(8000);
set @IDM = 3418;
set @IDO = '3430' 
select *
from wtcomValidRelationships as A
where (A.IDMember = @IDM) and ( @IDO in (3428 , 3430 , 3436 , 3452 , 3460 , 3472 , 3437 , 3422 , 3468 , 3470 , 3451 , 3623 , 3475 , 3595 , 3709 , 3723 , 3594 , 3864 , 3453 , 4080 ))
but these numbers (3428 , 3430 , 3436 , 3452 , 3460 , 3472 , 3437 , 3422 , 3468 , 3470 , 3451 , 3623 , 3475 , 3595 , 3709 , 3723 , 3594 , 3864 , 3453 , 4080 ) come from a select-statement. so if i use select-statement in this query, i get nothing back. this query like this one:select *
from wtcomValidRelationships as A
where (A.IDMember = @IDM) and ( @IDO in (select B.RelationshipIDs from wtcomValidRelationships as B where B.IDMember = @IDM))
I have checked that man can use IN-Operator with select-statement. I don't know why it doesn't work with me. Could somebody help me? Thanks
I use MS SQL 2005 Server Management Stadio Express
Thanks a million and Best regards

SELECT Statement Works In SQL Server Management Studio But Not In SSRS

Mar 14, 2008



Hi,

I'm attempting to extract some yearly average figures from our DB. I've written a SELECT statement in SQL Server MS which returns exactly what I need:


SELECT YEAR, CAllSource, AVG(CallTotal) AS [Average calls per day]

FROM (SELECT COUNT(CallID) AS CallTotal, DATEPART(YEAR, Recvddate) AS Year, CASE WHEN CallSource IN ('Auto Ticket', 'Email')

THEN 'Email' WHEN CallSource IN ('Phone') THEN 'Phone' ELSE 'Other' END AS CallSource

FROM Calllog where

DATEPART(MONTH, Recvddate) = 3

AND DATEPART(dw, RecvdDate) NOT IN ('7', '1')

GROUP BY RecvdDATE, callsource) as sub

GROUP BY YEAR, CallSource

ORDER BY YEAR, CallSource

The problem is that when I attempt to use this in SSRS I get the following error:

"sub.Year is not a recognised DATEPART Option".

Now as you can see, "sub.Year" is not even mentioned in the expression. However I noticed that when running the query, SSRS automatically adds "sub." before the YEAR in the section highlighted in yellow above. a) Why is it doing this, and b) does anyone know of a workaround/fix?

Thanks
Matt

DTC Select Works - Insert Update Fails Cannot Begin Distributed Transaction

Mar 31, 2015

We have a rather large environment and have just a couple of boxes out there that we are getting cannot begin distributed transaction on inserts and updates but works fine on selects. Inserts and updates work fine outside the begin tran / commit so it's definitely DTC

We have checked the configuration on and the source box is set to No authentication required same for destination.

We have: Verified credentials running the service, changed them, same problem. Uninstalled and re-installed MSDTC per Microsoft instructions.

Have run all the tools for checking DTC DTCPing etc and followed those procedures which typically in the past has resolved any DTC issues. Other than swapping out the offending pc for a new one we are at a loss.

Select With IN Clause

Aug 3, 2006

Hi SQL Experts,

i have a strange problem

i have a variable which stores some values(ID) with single quote (so that i can use directlt inside the IN Clause of SELECT

Declare @DMSIDs AS VARCHAR(1000) -- variable declare,

Select @DMSIDs = '''DMS00046847'',''DMS00048305''' -- for test putting 2 correct values with escape characters

Select * from issue where id in (@DMSIDs) -- valid statment, but does not return any data
Select * from issue where id in ('DMS00046847','DMS00048305') -- same above constant value this returns data, but putting the values in varaible then trying fails.

The reason is i have a master table called issue and have another table [delta] where a particular column will store all the ID's of the issue table comma separated with single quote and i wanted to use something like below in my actual application

Select * from issue where ID in (Select distinct delta_ID from Delta_branch where date = getdate())
but since the above example with variable is not returning any data i wonder if such is possible in any other ways.

thank you for reading and helping me.

Question About Where Clause In A Select

Feb 28, 2008

Hi,

I have a simple select statement that joins a master and a detail tables using a single field. Looks somthing like this:

Master:
Field1 (Unique key)
more fields...
DateField (Index field)

Detail:
Field1 (unique key)
Field2 (unique key)
more fields....

The master has 100 thousand records and the detail has 100 million records.

If I had a statment "Select.....From Master, Detail" what would be the best way to write the where clause?

Would one of the following where clauses run faster than the other based on the number of records in the tables?

Where1:
where Master.DateField = value and Master.Field1 = Detail.Field1

Where2:
where Master.Field1 = Detail.Field1 and Master.DateField = value

CURSOR Select Clause

Use A Variable Along With The FROM Clause In SELECT Statement

Dec 28, 2004

I have a table 'table_list' which contains two columns, table_name and a record_count. This table stores a list of tables and their corresponding record counts.

What I am trying to do is, to be able to write a select statement, that can read each table name in the 'table_name' column, execute a select count(*) for the same, and update its record_count with the result of select count(*).

This is the code in my procedure..

DECLARE @tab_list CURSOR
set @tab_list = CURSOR FOR select * from table_list
OPEN @tab_list

DECLARE @tab_name varchar(256)
DECLARE @rec_cnt int
FETCH NEXT FROM @tab_list INTO @tab_name, @rec_cnt

select count(*) from @tab_name

This select is looping around along with FETCH till all the table names are exhausted and their counts are updated from the cursor back into the table.

Problem is that, I am not able to use select count(*) from @tab_name, and its not accepting a variable there.

Please help me to construct the select statement that is similiar to

x=<table name>
select * from x
where x is a variable and the table name gets substituted.

what is the syntax for it ?

Optimising Select Statements Which Has A ‘LIKE’ Where Clause.

Dec 14, 2004

Hi all

I have been doing some development work in a large VB6 application. I have updated the search capabilities of the application to allow the user to search on partial addresses as the existing search routine only allowed you to search on the whole line of the address.

Simple change to the stored procedure (this is just an example not the real stored proc):

From:
Select Top 3000 * from TL_ClientAddresses with(nolock) Where strPostCode = ‘W1 ABC’
To:
Select Top 3000 * from TL_ClientAddresses with(nolock) Where strPostCode LIKE ‘W1%’

Now this is when things went a bit crazy. I know the implications of using ‘with(nolock)’. But seeing the code is only using the ID field to get the required row, and the database is a live database with hundreds of users at any one time (some updating), I think a dirty read is ok in this routine, as I don’t want SQL to create a shared lock.

Anyway my problem is this. After the change, the search now created a Shared Lock which sometimes locks out some of the live users updating the system. The Select is also extremely SLOW. It took about 5 minutes to search just over a million records (locking the database during the search, and giving my manager good reason to shout abuse at me). So I checked the indexes. I had an index set on:

strAddressLine1, strAddressLine2, strAddressLine3, strAddressLine4, strPostCode.

So I created an index just for the strPostCode (non clustered).

This had no change to the ‘Like select’ what so ever. So I am now stuck.

1)Is there another way to search for part of a text field in SQL.
2)Does ‘Like’ comparison use the index in any way? If so how do I set this index up?
3)Can I stop a ‘Shared Lock’ being created when I do a ‘like select’?
4)Do you have any good comebacks I could tell the boss after his next outburst of abuse (please not so bad that he sacks me).

Any advice truly appreciated.

I have many invoices that haven't been paid (so they don't have a record on the customer payments). I know this, as i can for example do:
select * from invoices where invoiceID = 302247 (and i'll get one result)
select * from customer_payments where invoice = 302247 (and i'll get none results)

however, if i do the following:
select * from invoices where invoice_id not in
(select invoice_id from customer_payments)
I get nothing!!!???

It doesn't make any sense, as I should get at least 300 (including the 302247) - both invoiceids fields are int... so i just don't understand what's wrong?

thank you so much for any help!

Use Of User Defined In SELECT Clause

Jul 23, 2005

I'm having this query:SELECTss.subscription_id AS SubscriptionId,s.id AS ScopeId,s.[name] AS ScopeName,s.base AS ScopeBase,dbo.iqGetShapesByScopeAsString(s.id) AS ShapesAsStringFROMsubscription_scope ss,scope sWHEREss.subscription_id = @subscription_idANDss.scope_id = s.idORDER BYs.[name]The select only returns a single row but my database (SQL Server 2005CTP) seems to execute the "iqGetShapesByScopeAsString" function foreach row in the subscription_scope and scope tables. This is a bug,right? The function should be executed only once for each *returned*row in the SELECT, right? I believe that was the case in SQL 2k thoughI can't check it at the moment.// pt

Select Inner Join With Where Clause Problems

Jan 3, 2007

Hello All,

I have a question about a Select over 2 Tables,
with the Following Scenario (Not all Products (ARTICULOS) haves CARAC's on the CFG_CARAC_ARTICULOS table):

Picture of the tables here:
http://www.pci-baleares.com/pantallazoSql.jpg



We have per example 7 Slots (Motherboard, CPU, VGA Card, RAM, TOWER, etc...)
When we fill the Slot with a CPU-> Then we open the Slot for VGA CARD, we do the Followin Select:

SELECT dbo.ARTICULOS.*
FROM dbo.CFG_CARAC_ARTICULOS INNER JOIN
dbo.ARTICULOS ON dbo.CFG_CARAC_ARTICULOS.ID_ARTICULO = dbo.ARTICULOS.ID_ARTICULO

Ok it brings up ALL Graphic Cards because they dont depends on CPU

Now we go to the Motherboard Slot
And we make the following Select to obtain the compatible Motherboards:
SELECT dbo.ARTICULOS.*

FROM dbo.CFG_CARAC_ARTICULOS INNER JOIN

dbo.ARTICULOS ON dbo.CFG_CARAC_ARTICULOS.ID_ARTICULO = dbo.ARTICULOS.ID_ARTICULO

WHERE

((dbo.CFG_CARAC_ARTICULOS.ID_CARAC = 7) AND (dbo.CFG_CARAC_ARTICULOS.VALOR = 'PCI-E')) AND
((ID_CARAC = 1) AND (VALOR = '775'))

We check the motherboards if they support PCI-E (because we selected a Graphic card of that, and SOCKET 775 because the CPU)

But SQL return 0 Rows, if we do the following Select:
SELECT dbo.ARTICULOS.*


FROM dbo.CFG_CARAC_ARTICULOS INNER JOIN


dbo.ARTICULOS ON dbo.CFG_CARAC_ARTICULOS.ID_ARTICULO = dbo.ARTICULOS.ID_ARTICULO


WHERE


((dbo.CFG_CARAC_ARTICULOS.ID_CARAC = 7) AND (dbo.CFG_CARAC_ARTICULOS.VALOR = 'PCI-E'))

OR

SELECT dbo.ARTICULOS.*


FROM dbo.CFG_CARAC_ARTICULOS INNER JOIN


dbo.ARTICULOS ON dbo.CFG_CARAC_ARTICULOS.ID_ARTICULO = dbo.ARTICULOS.ID_ARTICULO


WHERE

((ID_CARAC = 1) AND (VALOR = '775'))

It return Rows, it happens just if the Where clause haves more as 1 specifications...

Any solution for it? It drives me crazy :D

Thanks and regards
Marc Hägele
