Having Problems with a Simple Query

Hey guys,
I am trying to run a query that will return all rows where a column is
completely empty of data.
I try this query:
select * from patients_visitInsurers
where CompanyID is NULL
But it does not return anything for me. If I try the reverse
select * from patients_visitInsurers
where CompanyID is not NULL
It returns rows that contain CompanyId values and rows that are blank.
What am I missing here? Thanks!
Do you have those blank values for CompanyID being NULL or just blank
string? Assuming CompanyID is character format, you can check:
SELECT <columns>
FROM patients_visitInsurers
WHERE COALESCE(CompanyID, '') = ''
Or
SELECT <columns>
FROM patients_visitInsurers
WHERE CompanyID IS NULL
OR CompanyID = ''

things, in my opinion. Empty of data means NULL (and you have the correct

You may also be safer to trim the data first, since it could contain a

WHERE RTRIM(CompanyID) = ''
However, you should not insert a blank string when you really meant NULL.
They are different in implementation, and they are different on a conceptual
level, as well.

I think that is where I am getting confused. I looked at the data
type and it says varchar and not null. If I look at the database,
nothing shows in the column for some rows, but I want to exclude rows
that do contain values in this field.
Thanks!

Right. So you need to have two concepts very clear:
NULL is the absence of any data whatsoever.
'' is an empty string. It is data, even if it is zero-length.
There is little point in setting this column to NOT NULL if you can stick an
empty string in there. In this specific situation, it is apparent that the
two concepts are interchangeable...

Having problems creating an SQL statement

I am having trouble getting the SQL statement to return stats from a survey the way I want them. The table is set up as:

ID Q1 Q2 Q3 Q4

Responses for each question (Columns Q1 – Q4) will be a numerical value between 1-5. I want to count how many 1s, 2s, 3s, etc. I have tried different joins, self joins, unions and sub selections but cannot get the correct output.

I would like to get the output for each question as a single record, and if possible have a final column with an average for the question. But I can do that in the data binding if needed.

Qs Ones Twos Threes Fours Fives

Q1 #of 1s #of 2s #of 3s #of 4s #of 5s

Q2 #of 1s #of 2s #of 3s #of 4s #of 5s

Q3 #of 1s #of 2s #of 3s #of 4s #of 5s

Any tips or SQL sample statements would be greatly appreciated.

It looks like 2 pivots will be needed to to transpose the data from your table layout to your desired output layout. If you're using Sql 2005, there is a Pivot feature but here i'll show you how you could do this using syntax that will work for Sql2000 or Sql2005.

I'll break each step down into it's own View. Each view will build off of the previous view(s).

The 1st View is named: VIEW_SurveyRotation1
In this View, we turn all the column headings (Q1, Q2 etc..) into data values and move all the answers into a single Answer column. This is actually the opposite of what we normally consider a pivot, but i still tend to think of it as a [reverse] pivot.

SELECT'Q1'AS Qs, Q1AS answerFROM dbo.SurveyUNIONALLSELECT'Q2'AS Qs, Q2AS answerFROM dbo.SurveyUNIONALLSELECT'Q3'AS Qs, Q3AS answerFROM dbo.SurveyUNIONALLSELECT'Q4'AS Qs, Q4AS answerFROM dbo.Survey

The 2nd View is named: VIEW_SurveyRotation2
In this View, we pivot the answer values back into column headings by querying against the results of our first View. As mentioned, there's more than one way to create a Pivot in Sql.

SELECT Qs,CASEWHEN answer = 1THEN 1ELSE 0END AS One,CASEWHEN answer = 2THEN 1ELSE 0END AS Two,CASEWHEN answer = 3THEN 1ELSE 0END AS Three,CASEWHEN answer = 4THEN 1ELSE 0END AS Four,CASEWHEN answer = 5THEN 1ELSE 0END AS FiveFROM dbo.VIEW_SurveyRotation1

The 3rd View is named: VIEW_SurveyAverages
Here we can create a simple set of Averages by querying against our first View

SELECT Qs,AVG(CAST(answerAS decimal))AS [Avg]FROM dbo.VIEW_SurveyRotation1GROUP BY Qs

The 4th and final View is named: VIEW_SurveyResult
In this View, we summarize the answer counts for each column and also join in the Averages

SELECT dbo.VIEW_SurveyRotation2.Qs, dbo.VIEW_SurveyAverages.[Avg],SUM(dbo.VIEW_SurveyRotation2.One)AS Ones,SUM(dbo.VIEW_SurveyRotation2.Two)AS Twos,SUM(dbo.VIEW_SurveyRotation2.Three)AS Threes,SUM(dbo.VIEW_SurveyRotation2.Four)AS FoursFROM dbo.VIEW_SurveyRotation2INNERJOIN dbo.VIEW_SurveyAveragesON dbo.VIEW_SurveyRotation2.Qs = dbo.VIEW_SurveyAverages.QsGROUP BY dbo.VIEW_SurveyRotation2.Qs, dbo.VIEW_SurveyAverages.[Avg]

I tend to work with complex sql queries by breaking it down into steps like this. It helps me to achieve the desired result. Then, once you've got it working, you can review it and see if you can eliminate any of the steps by consolidating them into fewer queries.

Do not have SQL 2005 so I did what you suggested mbanavige. I was able to combine it all into a single query and not use Views, just couldnt add in the averages that. But that was easy enough to do on the databind. Working like a charm. thanks.

Hi,

I'm having a really similar problem, also with surveys.

The only 2 differences are that (a) I don't want to summarise my results at all (b) I have multiple surveys in the same table so need to use an extra clause to pick out info for the survey I am interested in.

So far I have come up with...

TABLE

=====

SurveyID RespondantID QuestionID Answer

PIVOT QUERY

===========

SELECT RespondantID, [1] As Q1, [2] As Q2, [3] As Q3, [4] As Q4, [5] As Q5, [6] As Q6, [7] As Q7, [8] As Q8, [9] As Q9, [10]
As Q10 FROM (SELECT RespondantlD, QuestionlD, Answer FROM "3_Temp" WHERE SurveylD=3) AS preData PIVOT (
COUNT(Answer) FOR QuestionlD IN ([1], [2], [3], [4], [5], [6], [7], [8], [9], [10]) ) AS data ORDER BV RespondantlD

But it doesn't work and I can't figure out why.

What am I doing wrong?

having clause and where clause

for the following SQL statement
select ...
group by col1
having col1 is not null
Does it always return the same result as
select ...
where col1 is not null
group by col1
?
The "where" one should have better performance, is it always true?Having gets evaluated after all the results have been returned and
aggregates calculated.
Where gets evaluated as the results are returned. At which point the filter
happens depends on the execution plan, but it will always be prior to
aggregation.
As a rule, only criteria on aggregate columns (sum, count, etc.) should be
in the having clause. Everything else belongs in the where.
Where SHOULD always be more efficient than having. HOWEVER, it is possible
(but highly unlikely) that the difference could cause SQL Server to use a
different execution plan that by some freak coincidence would perform better
with the having than the where. This would be the exception, and I would be
rather surprised if anyone could come up with such a case.

clause is (IMHO) better code. Where should be used when you want to compare
on the values in each row, use haveing when you want to compare on
aggregated values. So the SQL to retrive all customers with orders totaling
more than $1000 from New York would be something like:
Select ...
Where State = 'NY'
Group By CustomerID
Having Amount > 1000

clause.
In case of having the result set is already generated and the filter is
applied.
And in this particular case that you have mentioned there won't be any
difference in the result (or so I think).

Having a problem inserting products

I am trying to write a bit of code that I can pass a brand name to. If the brand name exists I want to return the brandid to the calling middle tier. If the brand id does not exist I want to insert and then return the new brand id. The code below works unless the brand does not exist. Then it inserts, and I get an application exception. Next time I run the code it continues on until the next time it has to do an insert. So the inserts are working, but getting the value back is resulting in an application excetio.

Middle Tier Function (

privatestaticint GetBrandForProduct(clsProduct o)

{

int brandid = -1;// If the brand name comes in blank use the first word of the overstock product

o.BrandName = o.BrandName.Trim();

// if we do not have a brand for this productif (o.BrandName.Length == 0)return -1;Database db =CommonManager.GetDatabase();;try

{

// Get the brand id for this brand name// If it does not exist we will add it and STILL return a brand idobject obj = db.ExecuteScalar("BrandIDGetOrInsert", o.BrandName);string catid = obj.ToString(); *** FAILING LINE ***returnConvert.ToInt32(obj.ToString());

}

catch (Exception ex)

{

throw ex;return -1;

}

return brandid;

}

Stored Procedure: --------------------------------------------------

ALTER

PROCEDURE [dbo].[BrandIDGetOrInsert]-- Add the parameters for the stored procedure here

@.brandnameparm

AS

BEGIN

-- SET NOCOUNT ONSELECT brandidfrom brandswhereLower(brandname)=Lower(@.brandnameparm)-- If we found a record, exit

begin

insertinto brands(Brandname)values(@.brandnameparm)

end

SELECT brandidfrom brandswhereLower(brandname)=Lower(@.brandnameparm)

END

Hi Dear,

You have not mention that What is the Exception Message? I will be in better position to answer if you share Exception Message also...

but the One thing that seems wrong in your SP is

if@.@.rowcount> 0return

-- We did not find a record, so add a new one.

begin

insertinto brands(Brandname)values(@.brandnameparm)

end

@.@.rowcount return 0 if select statement didn't find any result......

so i think this check will be like this

if@.@.rowcount = 0return

-- We did not find a record, so add a new one.

begin

insertinto brands(Brandname)values(@.brandnameparm)

end

change this thing in your Store Procedure , if problem doesn't solve ..then post the Exception message...

Thank You

Best Regards,

Muhammad AKhtar Shiekh

Why would I do that? If the rowcount > 0 then I am happy with the first select and I want the SP to exit. It will have returned the brandid that I need. If the rowcount = 0 then I want to do the insert.

The ASP.NET codes an 'object not defined' exception. The brandid is not being returned after the insert - possible two rows are being returned also which I think an executescalar would not be happy with. How do I get only row to return in either case?

That's what i am saying but there is contradiction in Your SP...it is doing this

if@.@.rowcount> 0return

-- We did not find a record, so add a new one.

begin

insertinto brands(Brandname)values(@.brandnameparm)

end

It is actually inserting when RowCount is greater then 0 ( Not equal to 0)

sorry SP is no correct in above post, Remove the else part in the sp

ALTERPROCEDURE [dbo].[BrandIDGetOrInsert]

-- Add the parameters for the stored procedure here

@.brandnameparm

varchar(50)ASBEGIN-- SET NOCOUNT ONIFnotexists(SELECT brandidfrom brandswhereLower(brandname)=Lower(@.brandnameparm))begininsertinto brands(Brandname)values(@.brandnameparm)endSELECT brandidfrom brandswhereLower(brandname)=Lower(@.brandnameparm)END|||

i think the problem lies with this:

if (o.BrandName.Length == 0)return -1;

Database db =CommonManager.GetDatabase();

;

Notice the stray ; also the if statement is missing some braces

if (o.BrandName.Length == 0)
{
return -1;
}

Thats what looks wrong to me

has data

hi

tbl_cams_uploaddetails
tbl_cms_uploadDetails
if above 2 table has data than only i want to proceed other wise it will return 1

how to do this?

Try this, although it isn't totally clear what you mean by "it will return 1".

Chris

Code Snippet

IF NOT EXISTS ( SELECT 1

FROM tbl_cams_uploaddetails )

OR NOT EXISTS ( SELECT 1

FROM tbl_cms_uploadDetails )

BEGIN

RETURN 1

END

--Insert the code you wish to run after the condition check

I agree with Chirs..

Suppose if you want to proceed the data should not available on any one table then use the following code..

Code Snippet

IF NOT EXISTS ( SELECT 1 FROM tbl_cams_uploaddetails )

OR NOT EXISTS ( SELECT 1 FROM tbl_cms_uploadDetails )

BEGIN

RETURN 1

END

Suppose if you want to proceed the data should not available on both the table then use the following code..

Code Snippet

IF NOT EXISTS ( SELECT 1 FROM tbl_cams_uploaddetails )

AND NOT EXISTS ( SELECT 1 FROM tbl_cms_uploadDetails )

BEGIN

RETURN 1

END

Hard coding colum names in returned DetailsView table

Hi all,

We're selecting data from our database, FirstName, LastName, MobileNumber etc.

We're using the detaials view function to return it in a table upon selection. However all of the variables are returned as they are in the database, ie:without spaces.

We tried putting in spaces by selecting "AS what ever", but MSSQL does not seem to like spaces.

Any ideas?

Thanks

Hey,

Are you trying to make the column names have spaces, or the data/ If the first, try using:

AS "First Name"

OR

AS [First Name]

|||

You can rename the columns like this:

SELECT PhoneNumber AS [Phone Number]

I have a matrix where I am using the inscope function to return different
calculations depending on which group it is in (ie the detail is just the
value and the sub totals are sum(values)).
In for the subtotal group I have used:
iif(isnothing(sum(Fields!CurrentCount.Value)), 0,
sum(Fields!CurrentCount.Value)
But this is still returning blanks where there are no values in the group to
sum together.
Can anyone suggest how to get around this issue as it ?
TIA
Andrewyou might try iif(sum(Fields!CurrentCount.Value = nothing)

expression then you need to add a perenthesis onto the end. I tried to
recreate your problem and I get a 0. Weird

Handling Dataset in Stored Proc.

Hi,

I want to create and populate a dataset from store procedure with following to querires & return the dataset as a result.

Select * from billmain where billno = 12

Select * from billdetails where billno = 12

I am currently performing this task aa a resultset. Now I want to use Dataset. Anybody can send me sample sp which returns dataset as a execution of the sp.

A simple select statement would do. Call the stored procedure from your ADO.NET code and store the results of this stored procedure in a DataSet object.

CREATE PROCEDURE SelectTable @.billNo int

AS

SELECT columnName FROM Table WHERE billno=@.billNo

Hi,

Thanks fpr your Reply. This is working fine when I call it from my ADO.NET Code. But If I want to trf. Dataset as a return result of the said stored proc. where I will be doing multiple select in more then one table. So if I call it only once I can complete all task in a single call. In addition I want to marshal the job to server. So, In this case now tell me what should I do.I don't want to use CLR-Integrated stored procedure. In this case can How can I handle Dataset in above mentioned manner in a standard T-SQL stored procedure?

You can return more than one SQL Server resultsets from a single stored procedure, see the example below.

Chris

CREATE PROCEDURE SelectTable @.billNo int

AS

SELECT columnName

FROM BillMain WHERE billno=@.billNo

SELECT columnName

FROM BillDetails WHERE billno=@.billNo

GO

handle store procedure return 2 table

I have a sp that will do two select from two table. now, can datareader read both table or only dataset can? if datareader can? how to handle it?In .NET 2.0 you can return multiple datasets with a datareader. You use the NextResult() method to get the next set. Seehere.

Handle error in t-sql

Hi,

I would like to handle a sql error in t-sql and return a certain value in case error occurs. For example if I would like to add a record I want to return a certain identity value or maybe a status of transaction (0 for incomplete, 1 for succesfull trans).

If error occurs in sql I cannot return any values back to asp.net because of What I am doing at the moment is catching an error in asp.net and then displaying an error message. Is there a way to return only a return value to asp.net and somehow handle the error in t-sql?

Thanks

Yes, I believe that feature was added in SQL Express/2005, but I'm not familiar enough with it to give examples. Normally, I would not create a SQL query that would ERROR, but it might return an empty resultset, or other indicator that it failed. If I need to catch a true error, then catch it in a try/catch block in your code.
