CASE Statement in a SELECt

I want to do something like this in a SELECT where I set the value of one field based on another. Is this possible. If not are there any alternatives? Thanks
CASE WHEN [var_cpnt_brkpt_ct] = '0' THEN [enrc_cpnt_var_price_rt] = '0'

There is no CASE statement in SQL; we are a declarative language. We have a case expression! There is no control flow, like you are trying to write. You do not even know that fields are columns. This is as silly
as asking for the color the feathers on a fish.

T-sql case statement in a select

When I execute the following t-sql 2012 statement, the "NO Prod' value is not
being displayed from the sql listed below:
SELECT DISTINCT
IsNull(cs.TYPE,'') as type,
CASE IsNull(Course.TYPE,'')
WHEN 'AP' then 'AP Prod'
WHEN 'IB' then 'IB Prod'
WHEN 'HR' then 'HR Prod'
WHEN '' then 'NO Prod'
END AS label
FROM CustSection cs
INNER JOIN dbo.Person p on P.personID = cs.personID
Left join customCustomer cs564 on cs564.personID = p.personID and
cs564.attributeID ='564'
   where ( cs.type is null and cs564.attributeID = null)
     or
    (cs.type IN ('HR','AP') OR
      (cs.type='IB' AND SUBSTRING(cs.code,1,1)='3'))
ORDER BY label
What I want is for 'NO Prod' to be displayed when
cs.type is null and cs564.attributeId is null.
Thus can you tell me how to fix query above so the 'NO Prod' value is displayed in the
select statement listed above?

There is no CASE statement in SQL; we have a CASE expression. We do not use the old 1970's Sybase*- ISNULL(); we have COALESCE().
There is no such thing as a magic generic “type” in RDBMS. There is no such thing as a generic “code” in RDBMS. They have to to be “<something in particular>_type” and “<something in particular>_code” in a valid data model. How about blood_type
and postal_code??
There is no such thing as a generic “person” table in RDBMS. First of all, do you really have only one person, as you said?? But the important point is that these persons play a role in the data model – customers, students, etc. You are doing the wrong thing
and doing it badly. This table should not exist any more than a table of “Things” such exist.
And the reason you are beyond any real help is “attribute_id” which tell us that your schema is a total disaster of data and meta data mixed together in a non-RDBMS written in awful SQL. Based on cleaning up bad SQL for 30 years, it looks like you are an OO
programmer who never unlearned his prior mindset.
Why did you allow an encoding schema with blanks? Why do you have so many NULL-able columns?
SELECT DISTINCT is very rare in a properly designed schema. The DRI references assure that rows cam be matched. To get you started, look at this skeleton:
CREATE TABLE Products
(product_gtin CHAR(15) NOT NULL PRIMARY KEY,
product_type CHAR(2) DEFAULT 'XX' NOT NULL
CHECK (product_type IN ('AP', 'IB', 'HR', 'XX'))
The table name is a plural noun because it models a set (NOT an OO class).
The GTIN is an industry standard identifiers, and not have to invent our own.
The product_type (not blood_type, not automobile_body_type!) has a constraint that assures it is never NULL and never blank; I invented 'XX' as a default.
You need more help than you can get in a forum, but if you will follow Netiquette and post the DDL, we can get you started.

Nested CASE Statements in my SELECT of Query not calculating correctly

Hi - Am doing simple query to calculate statistics on students per course, the WHERE includes a parameter for Academic Year, so need If Academic Year = x then calculate age in the 1st Sept of that Year, then count number of 19Yrs&Over. Have included my successful lines for sum of other data, in my CASE the calculations are not distinguishing whether age is over or under 19 just counting all. Presume is problem with Date calculation or CASE?? Runs without error..I'm guessing I can nest a CASE?!
Many thanks!

Using null in CASE statements

Hi,
I have query with a case statement as follows:
SELECT * FROM table
WHERE
CASE WHEN :variable like 'A' THEN column END is null
WHEN :variable like 'B' THEN column END is not null;
This works fine when returning "column is null" but not when "column is not null".
Can I use a CASE statement like this?
Thanks
Lucy

My data is too complicated to show, but depending on the value of the bind variable in the statement I want to return all the rows in a query where the data in a particular column is either null or not null.For example, looking at the EMP table, if my bind variable is whether I want to show the top manager or not, if set to 'Yes' I would like to return all rows of the EMP table where mgr is null (i.e. the one row where ename is 'KING'), if it were set to 'No' I would like to return all the rows where mgr is not null (i.e. all the other rows). The difference with my query is that the column contains strings, not numerics.
I've used a CASE statement before where I equate the column to a particular value and that works fine, but I'm not sure how they deal with nulls. I've also tried DECODE and didn't get anywhere with that.
Thanks
Lucy

CASE statement in a dynamic page

I have written a query using a CASE statement in the select portion to evaluate column values and produce a text string. The query runs fine in sql*plus, but when I attempt to add the code to a dynamic page and compile it, I get the following error message:

Issue with TableAdapter Configuration Wizard and CASE statements

I am having an issue with using any CASE statements in the select clause for the Table Adapter Configuration Wizard (TCW). I can take any query without a CASE and it will run fine, but inserting any CASE statement in the Select such as:
SELECT
(CASE WHEN :ras_sort = 'D' THEN TO_CHAR(a.TRANS_DATE,'YYYYMMDD')
WHEN :ras_sort = 'C' THEN c.CLAIMDEP_NAME
WHEN :ras_sort = 'A' THEN TO_CHAR(a.ACCOUNT_NUMBER)
END) sort1
FROM xxxx
causes the TCW to error with "error in list of function arguments, 'THEN' not recognized" and several other errors. I have tried with and without parameters in the CASE and have tried both forms of the CASE statement. I have tried multiple queries, all that run with no problem outside of TCW and ODP, but this seems to be a real issue
Is this a known problem and are there any workarounds that will allow use of the TCW?
Thanks,
Dave

Hi Ashish,
perhaps you launch the Web service wizard from the wrong location (i.e. not selecting the SEI you want to use). Did you strictly follow the steps described in the <a href="http://help.sap.com/saphelp_nwce10/helpdata/en/44/f36fa8fd1d41aae10000000a114a6b/frameset.htm">documentation</a> for creating the web service?

Using Case statement to insert,update,delete the tables

Hi All,
I have to check the databse ,

insert/update/delete values in tables;
if it staging then
insert/update/delete values in tables;
if it is production then
insert/update/delete values in tables;
thers is function available to check the current database
For doing the about i am trying to write CASE statement like this
SELECT function,
case
when fun = 'developement' then insert into table1 values ('abcd','1234')
when fun = 'staging' then insert into table1 values ('abcd','1234')
when fun= 'production' then insert into table1 values ('abcd','1234')
else null
from dual
its throughing me an error
please help
Thanks,

Hi,
You can use CASE staement any place where an expression is expected.
For example, in:
UPDATE table_a
SET     col1 = exp1
,       col2 = exp2
WHERE   exp3 = exp4;all the expressions are labled lke expn.
Note that table_a, col1 and col2 are not expressions: you must hard-code these names, or use dynamic SQL.
So it's okay to say:
UPDATE table_a
SET     col1 = CASE
                   WHEN db = 'development' THEN 0
                   WHEN db = 'staging'      THEN 1
               END
,       col2 = CASE
                   WHEN db = 'development' THEN NULL
                   WHEN db = 'staging'      THEN col2
               END
WHERE   db != 'production';In this example:
in the development database, col1 is set to 0 and col2 is set to NULL
in the staging database, col1 is set to 1 and col2 is unchanged (that is, set to what it already was)
in the production database, nothing is changed (the WHERE condition is always FALSE)

Creating view containing case statements received error ORA-22992

We have a create view referencing table through dblink. The select statement in the create view has case statements, when running the Select statement alone, results are return. However, when executing the create view, it returns:
SQL Error: ORA-22992: cannot use LOB locators selected from remote tables
22992. 00000 - "cannot use LOB locators selected from remote tables"
*Cause: A remote LOB column cannot be referenced.
*Action: Remove references to LOBs in remote tables.
One of the source table has LOB column but not in the select statement. The strange thing is when removing the case statement from the select, create view works fine. Can anybody tell me what caused the error and how to fix it?

What is your 4 digit Oracle version?
Try rewriting the query to not use ANSI SQL92 joins. I found a link where this solved a problem similar to yours.

But, look at this curious thing: I re-write the query as follows:
SELECT A.ID, A.ID_REF, A.EVENDATE, B.DESCRIPTION
FROM A@ORCL A, B@ORCL B
WHERE A.ID_REF = B.ID_REF;
and it works fine... It seems like Oracle don't like the ANSI SQL92...

Fixing ORA-22992 “cannot use LOB locators selected from remote tables” error
You have migrated your Oracle 9i database to 10g and a distributed statement which worked fine in 9i now is getting error ORA-22992 “cannot use LOB locators selected from remote tables”. Even though the related remote table(s) does not contain any LOB column datatype.
FIX:
There is a bug on 9i,10g, and 11g that is related to this error. It is being fixed in 11.2. It can also be backported for previous 9i, 10g and 11g releases under the latest patchsets.
You may also do a workaround as follow:
Modify the affected SQL by adding the TO_CHAR function. For example:
-- Original SQL:
SELECT NVL2('a', 'b','c' ) FROM dual@remote_db;
-- Modified SQL:
SELECT TO_CHAR(NVL2('a','b','c')) FROM dual@remote_db;

Help with multiple case statements

Hello,
I am new to BO. I am on XI 3.0. SQL 2005. In Designer, I am trying to create a measure in a financial universe that would end up being multiple case statements within one select. This is what I tried to do, but it doesn't work with the two case statements. Can I use an ELSE leading into the second CASE WHEN somehow? How can I accomplish this? Sorry for my ignorance!
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month = 12 THEN dbo.ClientBudgetMonth.Stage1Sales END
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month = 11 THEN dbo.ClientBudgetMonth.Stage1Sales END
Any Suggestions?
Thanks,
Holly

Holly,
I don't know enough about your data or requirement to provide a solution, however, the construct that you post will not work because it causes you to build an object with multiple case statements when only one case statement per object is permitted. From what I see in your code I would be inclined to combine the two statements into one as such:
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month in (11,12) THEN dbo.ClientBudgetMonth.Stage1Sales else null END
Thanks,
John

Performance in a case statement

Hi
I have a query like this -
SELECT
MAX(CASE WHEN field1 = 'xyz' THEN field2 END) AS alias1,
MAX(CASE WHEN field2 = 'abc' THEN field2 END) AS alias2
FROM table1
WHERE
field1 = 'xyz' and
field2 = 'abc' and
some fixed condition
Please note that the conditions in where clauses are same as corresponding case statements apart from one fixed condition.
In the actual query there are ~15 such conditions and 15 case statements for each selected field.
I have put the where clause to reduce the number of rows getting returned from the table.
My question is - what happens in terms of performance if I remove the where clause here. In other words will above query perform better or same as this
SELECT
MAX(CASE WHEN field1 = 'xyz' THEN field2 END) AS alias1,
MAX(CASE WHEN field2 = 'abc' THEN field2 END) AS alias2
FROM table1
WHERE
some fixed condition
Thanks
Kumar

It really depends on what you query is trying to accomplish. The two queries are not the same. Your first will select rows where both field1 = 'xyz' and field2 = 'abc', while the second would also return rows where, for example, field1 = 'xyz' and field2 = 'def'. In which case, your alias2 would be null.

How can you change a drop down menu's selection in a case statement?

Hi,
I am trying to an array finding vi. This VI will take an existing xml file and after the user has selected his/her equipment, input, output, and frequency it will put all of those options into a string and search the xml file for that exact array name and display it on an output screen. The problem I am having is that my input and outputs selection needs to be a little different depending upon the equipment selected. I thought that I could use a case statement to change the input and output selectable options, but I have run into many snags with it. For one everytime I place a new Input and Output drop down menu in the case statement it wants to place a new one in the front panel (I only want one input and output not three I have two inputs and outputs hidden right now). I believe I am using the case statement wrong... Can anyone help change my input and output selectable options depending upon the equipment selected. Attached is my xml file, Array Find.vi (the original one), and Array Find_Test.vi (this is the one I am trying to modify).
Thanks,
dlovell

Hi dlovell,
There are 2 key things I'd recommend for the code - using property nodes to edit the strings in the combo boxes. Something like the following snippet:
Also, check your CPU in task manager when running the code. It will eat a whole core of your machine (25% quad core, 50% dual, 100% single) - that is because you are running the while loop and polling the control as fast as Windows will allow you to. Using Event Structures is a much more efficient way of working in this example.

Using a scalar user defined function in a select case statement

I have a simple select statement below and I want to have a case statement for some conditions based on the result of the udf returned value. I then want the returned value from that specific case statement to be returned where i have indicated 'DISPLAY
ZIPCODE' below.
SELECT
   CASE
         WHEN (SELECT Top 1 ZipCode FROM ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712) IS NOT NULL THEN 'DISPLAY ZIPCODE'
         WHEN (SELECT Top 1 ZipCode FROM ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,714) as r) IS NOT NULL THEN 'DISPLAY ZIPCODE'
         ELSE NULL
       END as Zipcode,
FROM
table1

SELECT COALESCE(ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712),ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712)) AS Zipcode
FROM table1
Nope. This is two function calls. coalesce(a, b, c, ...) is just syntatic sugar for
   CASE WHEN a IS NOT NULL THEN a
WHEN b IS NOT NULL THEN b
WHEN c IS NOT NULL THEN c
   END
But if you use isnull it's a different matter. (But isnull() permits two arguments.)

Case statement and Decode function both are not working in Select cursor.

I have tried both the Case statement and Decode function in Select cursor, but both the things are not working. On the other hand both the things work in just select statement.
See the first column in select (PAR_FLAG), I need to have this evaluated along with other fields. Can you please suggest some thing to make this work. And also I would like to
know the reason why decode is not working, I heard some where Case statement do not work with 8i.

I have tried both the Case statement and Decode function in Select cursor, but both the things are not working. Please define what you mean by not working even if your computer screen is near the internet we can't see it.
You should also look at the FAQ about how to ask a question
SQL and PL/SQL FAQ
Particularly *9) Formatting with {noformat}{noformat} Tags* and posting your version.
know the reason why decode is not working, I heard some where Case statement do not work with 8i.
Does this mean you are using 8i? Then scalar sub queries - selects within the select list, are not supported, along with CASE in PL/SQL.
Select DECODE(1,
