Dummy Where Clause Allowing Dummy Select Of Data - Utilizing Where Value = 1
Aug 30, 2007
Years ago, I remember while doing maintenance on a stored procedure seeing a 'Select x, y, z Where 'some value' = 1.
The function of this, I believe was to make the select work but not retrieve any actual values.
I am attempting to use this in an 'Insert Into Select values From' statement. This insert uses multiple selects via unions and I need a final dummy Select statement with no Where criteria.
What I am thinking may not even apply to what I need to do here.
If you recognize something even remotely near what I am trying to get across I would appreciate your sending me the code.
Another solution for me is just inserting one row with a final RecId = 6 and ' ' or 0 values for the other fields into a table
but I was hoping this would work.
Example:
Insert Into table
Select
1 as RecId,
' ' as field1,
field2
From test1
Where field2 = 'CA'
Union
Select
2 as RecId,
' ' as field1,
field2
From test1
Where field2 = 'NJ'
Union
/*Final Select */
Select
6 as RecId,
' ' as field1,
field2
From test1
Where 'some value' = 1'
Thanks much for your assistance!!!

Hello,I am working with a vb6 Windows application that runs on Tablet PC's.There are about five SQL Server 2000 databases that tie into theapplication. SQL Server MSDE runs on the tablets, and currently thereis only one instance running. There are efforts underway to upgrade theapplication to a .NET SmartClient.One enhancement that needs to be made to the current application willbe to provide a 'training mode' in the application for the users. Theuser will use the same application, but will work with 'dummy' datainstead of live data when in training mode.So far as I can tell, the easiest way to accomodate this would be tohave a second instance of MSDE with 'copies' of all the databasesrunning, but with the 'dummy' data contained in the databases copies.The application would have some mechanism for switching to 'trainingmode', and maybe by some change of a connection string, the dummy datawould be presented in the application.So aside from accomodating a 'training mode' feature in theapplication, the application would remain the same, and the databaseschema for the databases would remain the same. Only the data wouldchange for 'training mode'.I'm looking for some ideas on how to approach this. This application isused by five thousand field agents, and so we can't support thisimplementation on a case by case basis. So my thought is that thesolution needs to have 'few moving parts'. If we can do this and getaway from having two instances of MSDE, that would be great. I have nottried to set up identical databases in different directories on thesame instance (I figure that would cause a problem in a system table ortwo someplace, but maybe not), but its one thing I want to investigate.If you have any ideas on this, please share!Thank you for your help!CSDunn

No one answered this question, how do people normally insert dummy data into tables? I mean, where does the data typically come from? what process is used to insert the data? Note: This is for testing purposes, eventually to be tested in a Web-based front-end which I know nothing about.
thx,
Kat

Hello,
I have 4 tables: Folders, Files, Tags and FilesTags.
I need to insert some dummy data for testing as follows:
1. Insert 100 records in Tags tables.
Give Tag 01, Tag 02, Tag 03, ... to Tag names.
For this I have the following:
declare @i integer
select @i = 1
while @i <= 100
begin
insert into Tags ([text])
select 'Tag ' + right('000' + convert(varchar(3), @i), 3)
select @i = @i + 1
end
What I am missing is the following:
2. Insert 10 records in Folders tables.
Each folder should be filled as follows:
FolderID = New Guid
Name = "Name" + N (1, 2, 3, ...)
CreatedDate = Current Date
3. For each Folder I want to insert a random number of Files.
It can be added 0 to 10 Files.
Each file should be filled as follows:
FileID = New Guid
FolderID = Folder ID
Description = "Description" + Folder Number + File Number
4. For each file added associate it with a random number of Tags.
It can be 0 to 10 Tags and it should be done as follows:
Insert record in FilesTags where:
TagID = Random TagID taken from table Tags
That has still not be used in current File
FileID = Current FileID
Could someone, please, help me doing this?
My tables are as follows:
create table dbo.Tags
(
TagID uniqueidentifier not null
constraint PK_Tag primary key clustered,
[Name] nvarchar(200) not null
)
create table dbo.Folders
(
FolderID uniqueidentifier not null
constraint PK_Folder primary key clustered,
CreatedDate datetime not null,
[Name] nvarchar(200) null
)
create table dbo.Files
(
FileID uniqueidentifier not null
constraint PK_File primary key clustered,
FolderID uniqueidentifier not null,
Description nvarchar(2000) null,
constraint FK_Files_Folders
foreign key(FolderID)
references dbo.Folders(FolderID)
on delete cascade,
)
create table dbo.FilesTags
(
FileID uniqueidentifier not null,
TagID uniqueidentifier not null,
constraint PK_FilesTags
primary key clustered (FileID, TagID),
constraint FK_FilesTags_Files
foreign key(FileID)
references dbo.Files(FileID)
on delete cascade,
constraint FK_FilesTags_Tags
foreign key(TagID)
references dbo.Tags(TagID)
)
Thank You,
Miguel

In 2000, BCP seemed the way to go. DTS packages would also work. My question is, in 2005, what is the best choice? I seem to remember that BCP ignored all referential integrity constraints, and applying them afterwords was a royal pain. I'm not a BCP expert by any means. Running this at the command line means using the DOS prompt correct?
What is 2005's answer to this?

Hello,
For sure that this is a dummy question but can you explain me how SQL Server reacts to the fact that we have the same application running in two different pc's and this two applications intent to insert,update, delete or even read a record from the same table
Does "he" blocks the record until one of them leave the table ??? And if the other tries to update at the same time ???
Thanks,
Paulo

Hi!
I'm new in SQL SERVER 2000 and i'm looking for some kind of predefined dummy table. You know something like the "dual"-Table in Oracle. I want to use it for queries like that:
Select 1, 'auto' from dummy_table
Does anyone know, if something like that in SQL SERVER 2000 exists?

It seems every month when I'm diluged by lots of data I fall back on olereliable, Excel. But, I get over 50,000 rows of data to scrub. A colleagueof mine suggested I use a database. Seems simple so far, but having dabbledin Access, it has always not so intuitive to understand. My question istwo-fold, is SQL a database. I believe its the language of some otherdatabase. If I'm corrent on the later, what database(s) use SQL?Tony

Guys - scenario/DDL/DML below
Create table #Periods (Period INT , Frequency INT , startdate datetime NULL , enddate datetime NULL )
insert #Periods (Period , Frequency , startdate , enddate)
select 0 , 3 , '01-Nov-2004' , '30-Nov-2004'
union all
select 1 , 3 , '01-Dec-2004' , '31-Dec-2004'
union all
select 2 , 3 , '01-Jan-2005' , '31-Jan-2005'
union all
select 2 , 6 , '01-Nov-2004' , '30-Nov-2004'
union all
select 3 , 6 , '01-Dec-2004' , '31-Dec-2004'
union all
select 4 , 6 , '01-Jan-2005' , '31-Jan-2005'
select * from #periods
Period Frequency startdate enddate
03 2004-11-01 00:00:00.0002004-11-30 00:00:00.000
13 2004-12-01 00:00:00.0002004-12-31 00:00:00.000
23 2005-01-01 00:00:00.0002005-01-31 00:00:00.000

36 2004-12-01 00:00:00.0002004-12-31 00:00:00.000
46 2005-01-01 00:00:00.0002005-01-31 00:00:00.000
For any frequency (in this simple example 6) where the 'lowest' period is not 0, I need to create dummy rows
so here I need to create the following
Period Frequency startdate enddate
06 NULL NULL
16 NULL NULL
I've built a temp table to identify the min period for each Frequency but am not sure where to go from here using this to do the inserts ?
select
min(Period) as MinPeriod ,
ResetFrequency
into #Periods2
from #Periods
group by ResetFrequency
select * from #CashFlow2
MinPeriodResetFrequency
03
16

I've written code that dynamically builds an sql query based onvarious constraint possibilities.The problem is the code would have been very complex had I not come upwith a dummy constraint as a kind of place holder in the statement.To avoid complex logic that determines if there was another constraintbefore any other constraint and hence the need to add, say, AND ornot, I came up with a dummy constraint so that every subsequentconstraint will begin with AND. There's no need to determine whetherto add AND or not. This makes the coding much simpler because allthat needs to be done is ask if a certain condition exists then addthe constraint along with AND in front every time.So what I did was create the statement like this:SELECT elapsed_time AS ET from Table1 WHERE 1 > 0 AND 1stConstraintAND 2nd Constraint and so on.See if the 1 > 0 condition were not there it would be necessary tofirst determine the first actual contraint and not add AND in front ofit and then add the rest with ANDs in front of every one.I should add that the user does not have to select any constraint andthat's the problem. I need to stick that WHERE 1>0 in there so thatthere doesn't need to be a determination of which other, if any,constraints are selected.Even if my explanation above is not well understood, believe me thefront-end coding is much easier this way.My question is does the 1 > 0 conditional check present the databasewith any significant overhead or as far was dummy constraints go isthis as good as any other?-David

Hi AllCan you please help me with a few queries on adding a header line andpadding rows out.I apologise profusely for not providing the DDL for this, but I don't haveit. All I have is stored procedure that I'm trying to edit to make thefront-end app display the right data.The relevant part of the stored procedure that I'm working on is as follow:Declare StockHelpCursor Scroll Cursor ForSelect s.StockID,ISNULL(sd.ShortDescription, s.StockID) +space(30-len(ISNULL(sd.ShortDescription,s.StockID))) +pl.name +space(10-len(str(pl.name,10,3))) +sp.currencyid + str(sp.sellingprice,10,3) +space(10-len(str(sp.sellingprice,10,3))) +str(sq.quantityinstock)From Stock s, StockDescriptions sd, StockQuantities sq,StockPrices sp, PriceLevels plWhere (s.StockID Like @theID) And(ISNULL(sd.ShortDescription, sd.StockID) Like @theName) And(s.StockID=sd.StockID) And(s.StockID=sq.StockID) And(s.StockID=sp.StockID) And(sp.PriceLevelID=pl.PriceLevelID) And(sd.LanguageID=@theLanguageID) And(sp.CurrencyID=@theCurrencyID)Order By s.StockIDOpen StockHelpCursorPLEASE NOTE: this query works fine apart from the following problems:1) Creating a header line - I need to insert a header line to this cursorfor the field headers, as the app is stripping off this header. I wasthinking of creating a var, sticking it in-between the Declare and theSelect part and inserting these field headers, but I don't know how to dothis. Any ideas?2) Padding the results - As you can see from the script, I have tried to padout the above fields as the app's output window is basically a textbox, butthey just don't line up.NOTE: I'm using the 3 in the str(xxx,10,3) bit to make my numbers show at 3decimal places.Could you please give me some pointers on how I can pad these out correctly.ThanksRobbie

I have matrix with 3 row groupings
Parent, Child, Baby
I have a value in the data cell and also a dummy column grouping to show some % values.
The % is basically what the row subtotal represents as a % of all the data in the dataset.
The Parent row group also has a subtotal, so the % here will show all values within the parent as a % of all data.
I have interactive sorting on Parent, Child and Baby.
but what I want to do is this:
Interactive sorting of the parent-subtotal-percent column values to cause a physical reordering of the parents.
i.e. show me the parents in order of their "% as a total of the entire dataset"
Possible?

I want to create a raw SQL resultset for outputting to Excel with some artificial headers transposed over the top of the 2nd part of the Union's column names. The first part of the Union will be the Headers. Like this, the space to the left of the topmost columns is preferably empty ....
COL 1 COL2 COL3 COL4 etc. BEH BIG BPL etc.
************************************* INTAKT DEFEKT INTAKT DEFEKT INTAKT
************************************* B E B E B
I just want the text above as a 3 line header and there won't be any values obviously. Then the 2nd query will be joined to the above with a Union all. The 2nd query has all the same column names as what will be given in the first set above. What is the SQL Syntax for doing so? Do I have to use a from clause?

I'm working on a query in which I need to get few nodes values from the XML data by using the value from SQL column (MessageContentType) in this query. I'm able to get the nodes value when i hard code the value in the query but the problem is MessageContentType will vary from some records in the table, due to that I'm not getting the corresponding node values. I have tried few ways to get this value dynamically but I'm missing something.
Sample Table Data
MessageContentType | BodySegment
xx:ADT_A03_26_GLO_DEF | <ns0:ADT_A03_26_GLO_DEF xmlns:ns0="http://microsoft.com/HealthCare/HL7/2X">.....
Current Query - HardCode Script
SELECT
ID,MsgContentType
BODYSEGMENT,
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /xx:ADT_A03_26_GLO_DEF[1]/colxx[1]/colxx[1]','varchar(300)') AS TimeSpan
FROM
s
When i tried the below line of script, I'm getting this error "[color=#FF0000]The argument 1 of the XMLdata type method "value" must be a string literal.[/color]"
Concat MsgContentType Column
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /'+MsgContentType+'[1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan
To overcome that error i used sql column but I'm getting this error [color=#FF0000]XQuery [S.bodysegment.value()]: Syntax error near '[', expected a "node test"[/color].
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /[sql:column("MsgContentType")][1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan
I tried this line of script, i didn't get any error by timespan is coming as null, I do hope this script not pointing the correct node to traverse the sibling node.
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /*[local-name()=sql:column("MsgContentType")][1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan

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

I have a report where I am giving the users a parameter so that they can select which field they would like to sort on.The report is also grouping by that field. I have a gruping section, where i have added code to group on the field I want based on this parameter, however I also would like to changing the sorting order but I checked around and I did not find any info.
So here is my example. I am showing sales order info.The user can sort and group by SalesPerson or Customer. Right now, I have code on my dataset to sort by SalesPerson Code and Order No.So far the grouping workds, however the sorting does not.
Any suggestions would help.

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?

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__'

We've set up a report farm with two servers, both 64 bit with 4 CPUs each. One has 16Gig and the other 8Gig of memory. We're using Windows NLB and the load test software confirms that the NLB is working. When we run a number of concurrent reports, both servers get utilized, but they only work on a few at a time. The report server queue doesn't seem to be fully utilizing the hardware. From a prior post I've learned that the report server queue automatically runs 4 reports per CPU. This is not occuring for our setup. Has anyone else experienced the same? Are there any configurations that need to be set to open the queue up? The reports are heavy (300,000 records grouped and summed). Does this affect the queuing process?

SELECT DISTINCT CL.CLIENT_ID,CL.LOAN_SANCTION_DATE,MIN(CL.INWARD_DATE)AS Inward
FROM dbo.FILE_MASTER AS CL
GROUP BY CL.CLIENT_ID,CL.LOAN_SANCTION_DATE
and the plan is showing Index scan on index Indx_FM_department_ID .. Why it is not using Index seek , i guess i have both group by Columns in cover index included columns what is the use of cover index then ?
because if i am giving where condition before group by for specific Client ID , Loan Sanction Date it is telling to create separate index on client ID , Loan Sanction Date as per Execution Plan missing index detail ..

Two servers are configured with Windows 2008 / SQL server 2012 utililizing Always-On for HA. We need to upgrade both servers to Windows 2012 / SQL Server 2014 with minimum downtime(Time for Always-On failover). The upgrade to SQL 2014 is straight forward with for minimum downtime.The Windows upgrade(2008 -> 2012) is the problem. From what I have observed and read in blogs.The Windows node to be upgraded must be removed from the Windows cluster before the node can be upgraded to Win 2012.A Win 2008 and Win 2012 node can not reside in the same cluster. If this is true then the only option I can think of is to dump the DB on WIN 2008 server and restore on Win 2012. This is an outage(time it takes to dump and restore).Is there any other method to upgrade these two nodes utilizing Always-On of some other method without downtime?

Hello all,
We've had a problem for a few months now that has completely stumped us. We are running a heavily cursored massive data manipulation process on a 32 bit SQL Server instance running on a virtual machine, running ontop of VMWare, with the following specs
Processors: 2x2674MHz processors
Memory: 4GB
RAID 10 disk config
When we run our process on this machine, in total it runs in 30 hours.
When this process is run on another 32 bit server with the following specs
Processors: 8x3658MHx processors
Memory: 8 GB
SAN w/ RAID 5 disk config
It runs 25% slower
But here is the real kicker. When this process is run on a 64 bit server with the following specs
Processors: 8x3658MHz processors
Memory: 8 GB
SAN w/ RAID 5 disk config
It runs 75% slower.
This process consists solely of stored procedures written in TSQL. The weird thing is that on our smaller server, the CPUs' % utilization are evenly balanced (at 20-30%) when this large data manipulation process is running. However on the bigger servers, SQL Server latches onto a single processor and doesn't load balance across other processors. Such that what we're seeing is that only one processor out of the eight will be utilized and it will be throttled at 90% while the other 7 are at zero.
The default configuration settings in all three places.
Has anyone ever seen any behavior like this, where only one processor gets used by SQL Server during processing? Granted our processes are single threaded b/c they are using cursors but, it seems that the single thread shouldn't be restricted to one processor.
Any thoughts?

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.

I'm having trouble using the To clause in my select statement. The following errs out with
Incorrect syntax near the keyword 'to'.
use pubs
select
*
from
view_Rates to 'c: est.csv'
I also tried this and got same error:
use pubs
select
*
to 'c: est.csv'
from
view_Rates
