CASE Function Result With Result Expression Values (for IN Keyword)
Aug 2, 2007
I am trying to code a WHERE xxxx IN ('aaa','bbb','ccc') requirement but it the return values for the IN keyword changes according to another column, thus the need for a CASE function.
WHERE GROUP.GROUP_ID = 2 AND DEPT.DEPT_ID = 'D' AND WORK_TYPE_ID IN ( CASE DEPT_ID WHEN 'D' THEN 'A','B','C' <---- ERROR WHEN 'F' THEN 'C','D ELSE 'A','B','C','D' END )
I kept on getting errors, like
Msg 156, Level 15, State 1, Line 44Incorrect syntax near the keyword 'WHERE'.
which leads me to assume that the CASE ... WHEN ... THEN statement does not allow mutiple values for result expression. Is there a way to get the SQL above to work or code the same logic in a different manner in just one simple SQL, and not a procedure or T-SQL script.

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

Hello,
We're trying to launch a SSIS package throw a webservice. This WebService loads a configuration file with "myPackage.ImportConfigurationFile(pathConfig)" and assigns values to some variables with "myPackage.Variables.Item(Parameters.Keys.Item(i)).Value = Parameters.Item(i)". Seems to work.
I we execute the webmethod of the WebService, this works but only when we execute first time, the SSIS finished succesfully. But when we execute a second time the Webmethod, we've a lot of failure with messages:
The result of the expression "@[User::Email]" on property "ToLine" cannot be written to the property. The expression was evaluated, but cannot be set on the property.The result of the expression ""The Import of " + @[User::ExcelFile]+ " is successful"" on property "MessageSource" cannot be written to the property. The expression was evaluated, but cannot be set on the property.

Hello,
I have a business rule that says if PROD = ''XCDD' and ProductRollUp = 'XCSH' Then BillingType = 'Express Cash' or 'Payment Services'.
Is there a way to represent that rule with a CASE statement?
Thank you for your help!

Is there a way of taking a result from a query and pulling out a certain account number and displaying those account numbers - as fred? Eg. I have a drop down of account number (s) however they pull from a table that only displays them as account numbers. I would like to give more a description to certain account numbers that are pulled. Eg. account number 234 will be fred and account number 555 will be sam etc. Trying to add it to the query on the dataset is complicated, so I was wondering if I created an additional blank field with an expression to be able to do this?Â

I´m creating a report in SSRS 2005 where you can filter after month and year. The result is the total sale for that particular month. What I want to do, is adding an extra column to compare with the result in the same month last year. F.eks. say that I choose january 2008 I would like to see the results for january 2007.
I thought of writing an expression to do that, but as that isn't my stronges side I would appreciate some help

I have a package with an input column that is varchar(8000).
I want to strip the first byte off of this column and put it in one result column and the remainder of the field I want to go to a second column. If the input column is an empty string, I want to return NULL.
Pulling the first byte off works fine, no issues, however putting the remainder of the input column into an output column is giving me a little trouble.
If I use this expression:
LEN(FLD1) == 0 ? NULL(DT_WSTR,1) : SUBSTRING(FLD1, 2, LEN(FLD1) - 1))
I get an error that says my expression evaluates to a string of greater than 4000 bytes.
If I do this instead:
LEN(FLD1) == 0 ? NULL(DT_WSTR,1) : RTRIM(SUBSTRING(FLD1, 2, 7999))
The expression passes muster but I get the warning that I will be truncating the column at 4000 bytes.
In actuality, I don't care if the result column is truncated after 4000 bytes. I find the second solution to be a bit clunky and I'm wondering if anyone can give me a reason why the first solution won't evaluate but the second will?

Which data type should I use for the variable, RowCount? I've tried Int16, Int32, Int64.

How do I automatically assign a new cardcode-number? (according to the following formula: highest existing number + 1)
Scenario:
-There are two types of business partners: Customers and Suppliers.
-Customers have the value 'C' in the colomn CardType.
-Suppliers have the value 'S' in the colomn CardType.
-Customers have the following syntax 'C123456' in the colomn CardCode.
-Suppliers have the following syntax 'S123456' in the colomn CardCode.
-Existing CardCode-values in the DB for the Customers: C000001 - C100599.
-Existing CardCode-values in the DB for the Suppliers: S000001 - S200199.
The idea is that when a user creates a new business partner, the CardCode should be automatically filled when a new assigned number (highest existing number + 1), according to the value that is selected in CardType (either the letter 'C' or 'S').
What's been done so far:
SELECT top 1
(CASE
WHEN CardType='C' THEN (SELECT top 1 'C' + '' + cast((substring(T0.CardCode, 2, 7) + 1) as varchar) as [nummer]
FROM OCRD T0
WHERE T0. CardCode like 'C%' AND T0. CardType='C'
order BY T0.CardCode desc FOR BROWSE)
WHEN CardType='S' THEN (SELECT top 1 'S' + '' + cast((substring(T0.CardCode, 2, 7) + 1) as varchar) as [nummer]
FROM OCRD T0
WHERE T0. CardCode like 'S%' AND T0. CardType='S'
order BY T0.CardCode desc FOR BROWSE)
END)
FROM OCRD T0
The current result:
The result that it gives is 'C100600'.
The problem however is that it always gives this result and does not take into account what has been selected in CardType.
When I add the following: "order BY T0.CardCode desc FOR BROWSE" it gives the result 'S200200'.
So, what does work is that it takes the highest existing value and adds 1. But what doesn't work is the taking account what value is selected in CardType.
Does anyone know how I can make this work?

Example:
Select StoreId from tblStores
S1
S2
S3
S4
I want to display a more friendly name. I have been using a case statement:
select case
WHEN storeId = 'S1' THEN 'NY Store'
WHEN storeId = 'S2' THEN 'CA Store'
...
end AS StoreName
If I am doing a simple 1:1 mapping like that, is there a better way than using a case statement (without creating/modifying tables)?

As the topic suggests I need the end results to show a list of shows and their dates ordered by date DESC.
Tables I have are structured as follows:
SHOWS
showID
showTitle
SHOWACCESS
showID
remoteID
VIDEOS
videoDate
showID
SQL is as follows:
SELECT shows.showID AS showID, shows.showTitle AS showTitle,
(SELECT MAX(videos.videoFilmDate) AS vidDate FROM videos WHERE videos.showID = shows.showID)
FROM shows, showAccess
WHERE shows.showID = showAccess.showID
AND showAccess.remoteID=21
ORDER BY vidDate DESC;
I had it ordering by showTitle and it worked fine, but I need it to order by vidDate.
Can anyone shed some light on where I am going wrong?
thanks

which returns me the following result :

The problem is at the lkp_val_infosystem where it returns 3 instead of 1 in the total_infra column. How do I correct my case stmt to return the correct no of projects breakdown by different project type? Currently, only the total_prj which returns correct data.

I'm new to SQL Server and would like to add a calculated column to this query from the report writer in our ERP system based on the NextFreq case statement result.
Basically, I want to create a column called service with result as follows:
If IV.meter > NextFreq then the result should be 'OVERDUE'
If (NextFreq - IV.meter) <50 then the result should be 'DUE SOON'
Otherwise the result should be 'NOT DUE'
This is the code from the current report writer query:
Select IV.item, IV.meter, isnull(wt.name,0)as name, case when whh.meterstop is null then 0 end meterstop, whh.rejected, Case when cast(meterstop as int) > 0 then cast(meterstop as int) when meterstop is null then isnull(IV.meter,0) else isnull(IV.meter,0) end EndMeter, ISNULL(CAST(SUBSTRING(wt.name,1,4)as int),0) as LastFreq,
case when whh.rejected = 1 then ISNULL(CAST(SUBSTRING(wt.name,1,4)as int),0) when ISNULL(CAST(SUBSTRING(wt.name,1,4)as int),0) = 0 then 100 when ISNULL(CAST(SUBSTRING(wt.name,1,4)as int),0) = 100

Hello Group,
I'm still a bit new to T-SQL and am wondering how to get various LOWEST values from a table, rather than TOP values. There does not appear to be a keyword opposite of TOP in T-SQL.
My real problem is this: I know how to get the 2nd highest value, third highest value, etc...but how does one get the 2nd lowest value, third lowest value, etc?
Would anyone be able to help?
Thanks!!

I have a table with about 28 million records in it. Each row has an ID (PK), logged (datetime), IP varchar(15)
The data grows at about 14 million records per year. I'm going to be running queries on the table that extract the MONTH or YEAR from the logged column. In Foxpro tables I would have created indexes on YEAR(logged) and MONTH(logged) so my queries would run faster. Is this possible/necessary in SQL Server?

INNER JOIN TBL_Pick_Items I ON I.PickTypeID = L.PickTypeID
INNER JOIN TBL_Pick P ON P.PickItemID = I.PickItemID
WHERE L.PickTypeID = ' + CAST(@TypeID as varchar) + '
AND CaseID = ' + CAST(@CaseID as varchar)
END
RETURN @RTN
END
Each time I try " RETURN EXEC(@RTN) " or something similar I get an error.
I have tried executing the tsql and assigning the result to a varchar and returning that varchar but i get an error.
Anyone with any ideas?

This is my first post and I am probably not using the correct terminology but I will try. I want to compare the value of one of my fields in a result set to the value of the same column/field, but from the previous row in the result set. I am trying to identify the row in the result set when the value in a specified column changes value. I want to identify this row by placing a 1 in the last column. If that value did not change, then place a 0 in the last column.
I am not sure if this will make sense to anyone out there. Please let me know if more clarification is needed and I will try to provide it. Thanks for all your help in advance.

Ok, for a bunch of cleanup that i am doing with one of my Portal Modules, i need to do some pretty wikid conversions from multi-view/stored procedure calls and put them in less spid calls.
currently, we have a web graph that is hitting the sql server some 60+ times with data queries, and lets just say, thats not good. so far i have every bit of data that i need in a pretty complex sql call, now there is only one thing left to do.
Problem:
i need to call an aggregate count on the results of another aggregate function (sum) with a group by.
*ex: select count(select sum(Sales) from ActSales Group by SalesDate) from ActSales
This is seriously hurting me, because from everything i have tried, i keep getting an error at the second select in that statement. is there anotherway without using views or stored procedures to do this? i want to imbed this into my mega sql statement so i am only hitting the server up with one spid.
thanks,

Periodically throughout the day a report is manually pulled from a SQL Server database. Â Is their a way w/o me adding a field to the database to have the result set return the "new" results? Â For example, lets say this is our DDL
Create Table OneTwoThree
(
id int
,date11 datetime
,firefly varchar(10)
)
Insert Into OneTwoThree Values (1, '08/03/2015 18:43:32.012', 'Hi'), (2, '08/03/2015 18:44:11.011', 'No'),
(3, '08/03/2015 19:36:33.011', 'Second'), (4, '08/03/2015 19:37:33.011', 'Alpha')
Prior I could use this syntax, but that was only with needing to generate 1 result set. Â
Select id, convert(varchar(10), date11, 101) As [Date], firefly from onetwothree
where CONVERT(varchar(10), date11, 101) < CONVERT(varchar(10), GetDate(), 101)
Looking at my datetime values, let's say the 1st was generated at 18:45, obviously the 1st two records in the table would be returned. And let's say a 2nd time I need to generate I want to exclude the 1st two entries as they have already been verified. How can I do such w/o adding a field to the table?

Any assistance would be so helpful !!
We have 2 tables.. lets call them INV and COST
Table INV and COST have 3 related columns, namely ID,AMOUNT and VAT. As shown below...
ID | AMOUNT | VAT ( INV TABLE )
1 |20.125 |2.896
2 |10.524 |1.425
ID | AMOUNT | VAT ( COST TABLE )
1 |20.125 |4.821 .... different to ID 1 in INV Table
2 |10.524 |1.425
If you look above, I need to sum the AMOUNT and VAT columns and get a value for each ID, then compare the two tables and get the ID's that have different values...in this case I would need a result saying ID1 as the total of INV TABLE ID1 (23.021) is different to the corresponding ID1 row in COST TABLE (24.946)
Thats it ???
Please could someone out there offer some ideas ?
THANKS
JON
