Adding Case Statement To Existing Query

Apr 3, 2008

I was asked to add an additional column to an existing query. I'm using Microsoft Query with a MS SQL 2000 server, and don't have much knowledge of SQL in general. Here's the existing query:



SELECT A.COMPANYCODE,
A.INVOICENUMBER,
A.LINENUMBER,
A.SONUMBER,
A.CUSTOMERCODE,
A.SHIPPERNUMBER,
A.INVOICEDATE,
A.ITEMCODE,
A.QUANTITYINVOICED,
A.UNITPRICE AS 'InvPrice',
A.QUANTITYINVOICED * A.UNITPRICE AS 'ExtInvPrice',
INVENTORY.UNITPRICE AS 'StdPrice',
INVENTORY.STANDARDCOST,
A.QUANTITYINVOICED * INVENTORY.STANDARDCOST AS 'ExtCost',
(A.QUANTITYINVOICED * A.UNITPRICE) - (A.QUANTITYINVOICED * INVENTORY.STANDARDCOST) AS 'GM$',
(INVENTORY.UNITPRICE - A.UNITPRICE) * -1 AS 'PriceListDiff'
FROM ABW.DBO.SALESANALYSISHISTORY A,
ABW.DBO.INVENTORY INVENTORY
WHERE INVENTORY.COMPANYCODE = A.COMPANYCODE
AND INVENTORY.ITEMCODE = A.ITEMCODE
AND ((A.COMPANYCODE = 'csp')
AND (A.QUANTITYINVOICED <>$ 0)
AND (A.INVOICEDATE BETWEEN '03/1/08' AND '03/31/08'))
ORDER BY A.INVOICEDATE,
A.ITEMCODE



They want a column added to the current query where if A.Unitprice is greater than or equal to Inventory.UnitPrice then populate the column with A.QuantityInvoiced*A.UnitPrice. I posted on another forum, and the advice I got was to add this:


SELECT NewColumn = CASE
WHEN A.Unitprice >= Inventory.UnitPrice THEN A.QuantityInvoiced * A.Unitprice
ELSE 'null'
END,
FROM ABW.DBO.SALESANALYSISHISTORY A,
ABW.DBO.INVENTORY INVENTORY

I'm not sure how to integrate it to the current query, so I've tried running it by itself, and I get the error: Didn't expect 'A' after the SELECT column list.

Any help would be greatly appreciated to modify the current query to display the new column.

Transact SQL :: Adding Case When Statement With Group By Query Doesn't Aggregate Records

Aug 28, 2015

I have a a Group By query which is working fine aggregating records by city.  Now I have a requirement to focus on one city and then group the other cities to 'Other'.  Here is the query which works:

Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars' 
From [Output-MarketAnalysis]
Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active'
Group by [City]

Here is the result:

St. Louis 1000
Kansas City 800
Columbia 700
Jefferson City 650
Joplin 300

When I add this Case When statement to roll up the city information it changes the name of the city to 'Other Missouri City' however it does not aggregate all Cities with the value 'Other Missouri City':

Select [City]= CASE WHEN [City] = 'St. Louis' THEN 'St. Louis' ELSE 'Other Missouri City' END, SUM([Cars]) AS 'Total Cars' 
From [Output-MarketAnalysis]
Where [City] IN ('St. Louis','Kansas City','Columbia', 'Jefferson City','Joplin') AND [Status] = 'Active'
Group by [City]

Here is the result:

St. Louis 1000
Other Missouri City 800
Other Missouri City 700
Other Missouri City 650
Other Missouri City 300

What I would like to see is a result like:

St. Louis 1000
Other Missouri City 2450

SQL Statement, Adding Two COUNT/CASE Statements

Dec 12, 2007



SELECT COUNT(DISTINCT CASE WHEN visit_type = 0 THEN visitor_id END) AS [New Visitors],
COUNT(DISTINCT CASE WHEN visit_type = 0 THEN visitor_id END) AS [Returning Visitors]
FROM content_hits_tbl
WHERE (hit_date BETWEEN DATEADD(mm, - 1, GETDATE()) AND GETDATE())

=======================

How do I add up both COUNT/CASE columns? Would it be:
SUM([New Visitors] + [Returning Visitors]) AS Total


I tried this and it doesn't work. I get invalid column names error for both.

I have even tried:
SUM([COUNT(DISTINCT CASE WHEN visit_type = 0 THEN visitor_id END)] + [COUNT(DISTINCT CASE WHEN visit_type = 0 THEN visitor_id END)]) AS Total

You would think that there would be some gui functionality in VS08 that would do this...


Thoughts are greatly appreciated!

Using Query In CASE Statement

Mar 4, 2008

Why couldn't they make SQL syntax error mistakes a little less vague.

Anyway, I was wondering, is it possible to use a set in your case statement?

CASE
(
select distinct tbhtg.TrainingBlockHistoryTypeGroupingCd
from tblTrainingBlockHistory tbh
inner join tblTrainingBlockHistoryType tbht on tbh.TrainingBlockHistoryTypeCd = tbht.TrainingBlockHistoryTypeCd
inner join tblTrainingBlockHistoryTypeGrouping tbhtg on tbht.TrainingBlockHistoryTypeGroupingCd = tbhtg.TrainingBlockHistoryTypeGroupingCd
where (select dbo.fnTrainingBlockStatus( 1234, getdate())) = tbht.TrainingBlockHistoryTypeCd
)
WHEN 'S' then (COUNT(DISTINCT TRD.TrainingBlockHistoryId) = COUNT(DISTINCT SWT.TrainingBlockHistoryId)) end


This is giving me an error on the WHEN statement. The error is "Incorrect syntax near '='" Have no idea how to fix this.
But the select statement seems to work, and as far as I can tell, that is how you write a CASE statement.

Also, this CASE statement is inside the HAVING clause - is that going to be a problem?

Help On Adding Another Filter Statement On The Query

May 27, 2008

Hi everybody have this query that list all the duplicate records meaning the occurence of pubinfid in more than one row. This gets me fine. Iwant thought to insert a where clause that further filters the result where pubid between 30 and 33. I tried placing it after the FROM CLAUSE BUT DOESN'T GIVE me what I want it still includes records other than the between clause. Also I tried placing it after the HAVING clause but it includes records which has only one count.. Where could I place the where clause or is ther an alternative for this.



SELECT a.pubinfid, a.pubid, a.pubcount
FROM pubssubscribe AS a INNER JOIN
(SELECT pubinfid
FROM pubssubscribe
GROUP BY pubinfid
HAVING (COUNT(*) > 1)) AS b ON a.pubinfid = b.pubinfid

How Do You Hold The Value Of A CASE Statement For Further Use In The Query??

Feb 18, 2007

I have a select statement and I would like to know which when clause(1st set of whens) was fired and the value of the then for further use in my query.  I am wondering if this is possibly, and how it would be done.  If i try and set a @variable at the beginning of the case statament i get an error, here is my query         SELECT PIE.productID, PIE.quantity, CEILING((PIE.width/12.0)/0.5)*.5 as width, CEILING((PIE.length/12.0)/0.5)*.5 as length,                 ***throws an error**** @sqft = CASE  --- but the then clause of this CASE is the value i want for later use in this same query                                 WHEN CEILING((PIE.width/12.0)/0.5)*.5 > (2.0 * (CEILING((PIE.length/12.0)/0.5)*.5)) THEN CEILING((((CEILING((PIE.width/12.0)/0.5)*.5) * 1.5) *                                     CEILING((PIE.length/12.0)/0.5)*.5)/1.0)*1.0                                 WHEN CEILING((PIE.length/12.0)/0.5)*.5 > (2.0 * (CEILING((PIE.width/12.0)/0.5)*.5)) THEN CEILING((((CEILING((PIE.length/12.0)/0.5)*.5) * 1.5) *                                     CEILING((PIE.width/12.0)/0.5)*.5)/1.0)*1.0                                 ELSE CEILING((CEILING((PIE.length/12.0)/0.5)*.5) * (CEILING((PIE.width/12.0)/0.5)*.5)/1.0)*1.0                         END AS sqft,                         CASE                                 WHEN @custMarkup = 1 THEN (SELECT PML1 FROM ProductMarkup PM WHERE PIE.productID = PM.productID)                                 WHEN @custMarkup = 2 THEN (SELECT PML2 FROM ProductMarkup PM WHERE PIE.productID = PM.productID)                                 WHEN @custMarkup = 3 THEN (SELECT PML3 FROM ProductMarkup PM WHERE PIE.productID = PM.productID)                                 WHEN @custMarkup = 4 THEN (SELECT PML4 FROM ProductMarkup PM WHERE PIE.productID = PM.productID)                                 WHEN @custMarkup = 5 THEN (SELECT PML5 FROM ProductMarkup PM WHERE PIE.productID = PM.productID)                         END AS markup         FROM ProductsInEstimate PIE         WHERE estID = @estid

Using A CASE Statement Within A Select Query

Jul 25, 2006

Hi folks,

Hope you are all well.

I am using a CASE statement within a SELECT query to sum up values for different customers.

SELECT CR_CUST.Customer_Code,
'General_01' = CASE WHEN CR_PROD.Part_Class_Code = '01' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END,
'General_07' = CASE WHEN CR_PROD.Part_Class_Code = '07' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END,
'General_08' = CASE WHEN CR_PROD.Part_Class_Code = '08' THEN SUM(CR_INVOICE.Line_Value) ELSE 0 END
FROM CR_CUST
INNER JOIN CR_INVOICE ON CR_CUST.Customer_Code = CR_INVOICE.Customer_Code
INNER JOIN CR_PROD ON CR_INVOICE.Product_Code = CR_PROD.Product_Code
WHERE (CR_PROD.Part_Class_Code = 1 OR
CR_PROD.Part_Class_Code = 7 OR
CR_PROD.Part_Class_Code = 8)
GROUP BY CR_CUST.Customer_Code,
CR_PROD.Part_Class_Code

The above query produces the following results...

Customer_Code General_01 General_07 General_08
------------- ---------------- ---------------- ----------------
02210 10074.30 .00 .00
02347 7606.49 .00 .00
02210 .00 12618.42 .00
02347 .00 13131.63 .00
02210 .00 .00 4505.44
02347 .00 .00 5018.03


My question is this - is it possible to expand my SQL Query into a Sub Query so that each customers data appears on the same line of the results?, like so...


Customer_Code General_01 General_07 General_08
------------- ---------------- ---------------- ----------------
02210 10074.30 12618.42 4505.44
02347 7606.49 13131.63 5018.03


I can achieve this by writing my results into a temporary table and extracting the data with the following SQL Query, but I just thought it would be really cool if I could do it in one SQL Statement without using a temporary table.

SELECT Customer_Code,
SUM(General_01),
SUM(General_07),
SUM(General_08)
FROM #MyTempTable
GROUP BY Customer_Code


Thanks in advance,
Kev

Help With Query (count With Case Statement)

Mar 29, 2008

Hi,

I have the following query, that returns the proper count value I am looking for. I would like to modify it a little bit, but can't remember exactly how to do it.

select count(messageFromID) FROM tblMessage WHERE messageFromID = 1000) as OutBoundMessages

Basically now, it returns the "OutBoundMessages" column

I would like it to return "OutboundMessages_unChecked" and "OutboundMessages_checked" as well as "OutboundMessages_total" (I guess I could determine this value by adding the two values in the front end too. I definatley dont want to do a lookup to determine the total )

I determine if the column is "checked" or "unChecked" by a column in
tblMessage

For example

tblMessage.checked = 1 = ("checked")
tblMessage.checked = 0 = ("unChecked")


any help much appreciated..

thanks!

Transact SQL :: Using Case Statement With Update Query

I have a table A  and lookup table B.

table A:

SQL Server 2012 :: Filtering Query Using CASE Statement Within WHERE Clause

Aug 21, 2014

How I am using a CASE statement within a WHERE clause to filter data:

CREATE PROCEDURE dbo.GetSomeStuff
@filter1 varchar(100) = '',
@filter2 varchar(100) = ''
AS
BEGIN
SELECT

[Code] .

What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.

Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?

Problem Using Result From CASE In Another CASE Statement

Nov 5, 2007

I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.

Previously, I had been duplicating the CASE logic for both columns, like so:




Code Block...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE
[logic for condition 1]
THEN 'Condition 1 text'
WHEN [logic for condition 2]
THEN 'Condition 2 text'
WHEN [logic for condition 3]
THEN 'Condition 3 text'
WHEN [logic for condition 4]
THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...






This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.

This is what I'd like to do:



Code Block
...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,


shipment_status_text =

CASE shipment_status

WHEN 1 THEN 'Condition 1 text'

WHEN 2 THEN 'Condition 2 text'

WHEN 3 THEN 'Condition 3 text'

WHEN 4 THEN 'Condition 4 text'

ELSE 'Error'

END,
...remainder of SQL view...


This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.

Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?

Thanks,

Jason

Hi All,

I am having a server where replication is set up between 2 differnt databases. It is currently running. I want to add a couple of tables to the replication.

What can I do to publish the tables into the target database?

Adding Nodes To An Existing Cluster

Mar 13, 2008



Hello,

We currently have a 2 node Active/Passive 2 named instance SQL 2000 cluster. We will be chaning the configuration to Active/Active, basically moving 1 instance to the passive node (so we can take advantage of the resources on the passive node).

We would also like to add 3 nodes to the cluster making it a 5 node SQL cluster. What we are thinking of doing is basically making it an Active/Active/Active/Active with the 5th server being passive. The question I have is will I be able to add and install the 3 new nodes without having to redo the SQL cluster? Should I install the two new active nodes with the default SQL instace or do I have to install SQL with named instances? (actually I think the named instances is the way to go but then I wouldn't be posting here if I was sure about the answer).

Thx!

Adding A Default Constraint To An Existing Column

Mar 9, 2000

I cannot figure out how to add a default constraint to an existing column. The syntax I'm using is :

ALTER TABLE table_name WITH NOCHECK
ADD CONSTRAINT column_name DEFAULT (0)

This gives me a syntax error.

The column was originally added with a default constraint of 1 to a 2.6 million row table.
I dropped the existing constraint and need to add the new default constraint of 0 for that column.

Anyone have any ideas? Thanks in advance.

Adding And Populating A Column To Existing Table

Sorry I'm pretty new to SQL so I don't know if this is a simple question. I have a table, and I am trying to add a column to the table and populate this column using what would be called an 'IF' function in Excel.

Basically 'column A' has numbers in it. I want SQL to look at 'column A' and if the first 5 digits of the number in 'column A' are 00001, then put 'description A' into new column 'column B'. If the first 5 digits of the number in 'column A' are 00002, then put 'description B' into 'column A' etc.

Sep 11, 2006

I removed all constraints in order to load a bunch of data into a table, now I'm wondering if I can add an identity column to this table which does contain data or if I have to create a new table with the identity column and insert the data into that.

thx

Adding Reporting Services To An Existing SP1 Install

Mar 13, 2007

HI,



Is there an easy way to install reporting services on a machine that is already running sp1? When I initially isntalled Sql Server I did not install ssrs. Now, SP1 is installed and when I run the setup tool to install ssrs, it warns me regarding a "version change", presumablly because my media is not sp1, but RTM. Any ideas?
