Dummy Question

Jun 6, 2006

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

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!!!

SQL Dummy!

Jul 21, 2007

Thank you to the two persons who took time to respond to my question.

I have to tell you - I know absolutely NOTHING about SQL.

Can you please tell me in language a two-year-old could understand, "What is SQL?"

Dummy Question

Mar 3, 2004

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

Dummy Table?

Feb 17, 2004

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?

Create 'Dummy' Rows

Dec 6, 2005

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
26 2004-11-01 00:00:00.0002004-11-30 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

Accomodating 'Dummy' Data?

Jul 23, 2005

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

Question About Dummy Constraint

Jul 20, 2005

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

Inserting Dummy Data

Aug 27, 2006

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,

Create Dummy Data

Feb 24, 2008

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

Inserting Dummy Lines And Padding

Dec 2, 2005

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

Test - Populating Tables With Dummy Data

Aug 24, 2006

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?

Sort Matrix On Dummy Grouping Value/subtotal

Apr 23, 2008



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?

Transact SQL :: Creating Dummy Headers (column Names) With Union All

May 19, 2015

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?
