Multiple case statements with aggregates- SQL
Hi guys
Here is my ddl
create table TestTable
Bill_date DATE,
Phone_no NUMBER(10),
Planlvl1 VARCHAR2(20),
Planlvl2 VARCHAR2(20)
Revenue NUMBER
INSERT INTO TestTable
Values
('1/01/2014' , 64221, 'Bundle', 'SpecialPack1', '$23'),
('1/01/2014'' , 64221, 'Bundle', 'PlanA', '$32'),
('1/01/2014' , 65211, 'Bundle', 'SpecialPack2', '$3'),
('1/01/2014' , 65211, 'Bundle', 'SpecialPack1', '$23'),
('1/01/2014' , 66211, 'Bundle', 'PlanB', '$34'),
('1/01/2014' , 66211, 'Bundle', 'SpecialPack2', '$3'),
('1/01/2014' , 66222, 'Bundle', 'SpecialPack1', '$23'),
('1/01/2014' , 66222, 'Bundle', 'SpecialPack2', '$3'),
('1/01/2014' , 66222, 'Bundle', 'PlanB', '$65'),
('1/01/2014' , 32444, 'Non_bundle', 'Casual1', '$32'),
('1/01/2014' , 324441, 'Non_bundle', 'Casual2', '$76'),
('1/01/2014' , 65444, 'Non_bundle', 'Casual1', '$12'),
('1/01/2014' , 65444, 'Bundle', 'PlanB', '$98'),
('1/01/2014' , 54322, 'Bundle', 'PlanA', '$12'),
('1/01/2014' , 54322, 'Non_bundle', 'Casual', '$12')
Expected Outcome:
Bill_date PlanLvl2 PhonenoCount
'01/01/2014' 'SpecialPack1' 1
'01/01/2014' 'SpecialPack2' 3
'01/01/2014' 'Casual1' 1
'01/01/2014' 'Casual2' 1
'01/01/2014' 'PlanA' 1
'01/01/2014' 'PlanB' 1
Basically I have to count all the phone nos grouped by plans in a certain way:
If PlanLvl1 = Bundle, then I have to look at planLvl2 and see if that phone no has ' SpecialPack%' ,and also another plan,them 'Special pack' gets the priority and the phone no gets counted in the special pack.
In case when PlanLvl1 = Bundle and a phone no has both 'Special Packs' as their plans, then the phone no will be counted under the 'Special Pack' with higher Revenue.
In case where PalnLvl is 'Bundle' and a phone no has multiple 'Special Packs' and a non special, that ph no will only be counted once under 'Special Pack; of higher rev as compared to the special pack of lower rev.
Now there are also PlanLvl1 which are 'Non_Bundles' which means they do not have any 'SpecialPacks' but if a ph no with 'NonBundle' plan has 2 different plans under planLvl2, we need to count that ph no for eack planLvl2..
Then there is a scenario where a ph no can have bundles as well as non bundles and in that case we just have to count that ph no in bundles and not in non-bundles.
As I mentioned , 'SpecialPack2' will get a preference over special pack 1 if a phone no has got both of these
Hope this helps
I;m not sure exactly what your rules are since you specify both "In case when PlanLvl1 = Bundle and a phone no has both 'Special Packs' as their plans, then the phone no will be counted under the 'Special Pack' with higher Revenue" and "As I mentioned ,
'SpecialPack2' will get a preference over special pack 1 if a phone no has got both of these". I went with the rule "As I mentioned , 'SpecialPack2' will get a preference over special pack 1 if a phone no has got both of these" since that seemed to match
the result you say you want. I also changed the datatypes to valid SQL Server datatypes.

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,
HollyHolly,
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,

Executing multiple DDL statements with OracleCommand
hi..
im having trouble executing multiple ddl statements with the the oracle command object. i have tried to enclose them within Begin.. End; block but with no use.
this problem seems to occur only with DDL statements,.. as my DML like update, delete and Inserts seem to work fine when enclosed within the PL /SQL block.
single DDL statements also seem to work fine. so im guessing this has nothing to do with priviledges. any ideas?
my code as follows
OracleCommand command = new OracleCommand();
command.CommandType = CommandType.Text;
command.CommandText = string.Format(@"{0}",script);
conn.Open();
command.Connection = conn;
command.ExecuteNonQuery();
the script is read from a file, and looks like this. (note : i have removed any line breaks or any other characters)
BEGIN ALTER TABLE SYSTEMUSER DISABLE CONSTRAINT FK_USER_CLIENT; ALTER TRIGGER SET_SUBSCRIPTION_SUB_I DISABLE; END;
this is the error i get.
Oracle.DataAccess.Client.OracleException: ORA-06550: line 1, column 7:
PLS-00103: Encountered the symbol "ALTER" when expecting one of the following:
begin case declare exit for goto if loop mod null pragma
raise return select update while with <an identifier>
<a double-quoted delimited-identifier> <a bind variable> <<
close current delete fetch lock insert open rollback
savepoint set sql execute commit forall merge pipe.If I'm not mistaken, we're not allowed to issue DDL inside anonymoue block (or stored procedure) since DDL has implicit commit in it. But you still can execute DDL using EXECUTE IMMEDIATE or using DBMS_SQL package. Try changing your CommandText like this,
BEGIN
EXECUTE IMMEDIATE 'ALTER TABLE SYSTEMUSER DISABLE CONSTRAINT FK_USER_CLIENT';
EXECUTE IMMEDIATE 'ALTER TRIGGER SET_SUBSCRIPTION_SUB_I DISABLE';
END;Hope this helps,

Deepak GoyalHow is an index going to help in a query with no where clause or join?
Rhetorical question but it brings to light the problem. This query is going to produce a table/index scan precisely because there's no where clause.
You need to change the way you are thinking about the problem. The problem isn't that you need a better performing case statement, the problem is that you need to minimize the number of records you ask SQL Server to read from disk. You do that
by using a where clause or by joining to a smaller table.
Here's one option which should give you the desired results while performing much better:
create index idx_period_id on Table1 (period_id)
create index idx_pmc on Table1 (pmc) include (period_id)
select (select count(distinct period_id) from Table1 where period_id < 350) as Column1,
(select count(distinct period_id) from Table1 where period_id between 351 and 375) as Column2,
(select count(distinct period_id) from Table1 where period_id between 376 and 400) as Column3,
(select count(distinct period_id) from Table1 where period_id between 401 and 450) as Column4,
(select count(distinct period_id) from Table1 where period_id between 451 and 575) as Column5,
(select count(distinct period_id) from Table1 where pmc = 'UVS') as Column6,
(select count(distinct period_id) from Table1 where pmc = 'VAL') as Column7 -
How to create nested CASE statements in PL/SQL

Case statement with having null gives default result
Hello,
When we write a case statement with a not equal condition <> on a column and if that columns has null value the it gives the else value.
eg
Select Column_Name, Case when Column_Name <>Condition then 0 else 1 end as case_test from Table_Name.
Ideally null is not equal to the condition so the case should return 0 but it returns 1. Can anyone tell me why?In addition to the other posts:
NULL is an unknown value, when you say
col <> 1
and col is NULL, we don't know whether col is 1 or something else. Thus the condition evaluates to UNKNOWN. How UNKNOWN is handled depends on the context. In WHEN clauses as well as the IF statments, the effect that the code bracketed by IF/WHEN is not
entered. That is, UNKNOWN and FALSE yields the same result. In CHECK constraints, it's the other way round. If you have
CHECK (WHEN col <> 0)
rows where col is NULL are accepted.
When you work with SQL, no matter the database product, it's imperative to master three-valued logic, because it comes up all the time.
As I said, NULL is the unknown value. In practice, NULL has a distinct interpreation depending on the database column. For instance, NULL in a column called EndDate, usually means that the period (or whatever it is) is still open. So often when you work
with NULL values you use isnull to replace it with some value that fits the context, and finding that value takes some consideration. Blindly doing isnull(col, '') can lead to serious bugs, particularly if col is not a string column.

Be more specific. Post a complete script that you tried, and what output you expected from it. If you got an error, post the complete error message, including line numbers.

Multiple Select statements in EXECUTE SQL TASK in SSIS
Can we write multiple select statements in execute sql task(SSIS).
If possible how to assign them to variables in result statementHi ,
You can use below steps to set result set to variable.
1.In the Execute SQL Task Editor dialog box, on the General page, select the Single row, Full result set, or XML result set type(According to your result set).
2.Click Result Set.
3.To add a result set mapping, click Add.

Hello Folks,
I have this Query where am converting from Access to Oracle. Am little confused on how to write multiple CASE statements.Apprecitae your help.
round(Sum(IIf(recovery_flg = 'NONCASH FEE RECEIVED',
IIf(feepaid < FEE, FEE - FEEPAID, FEE),
0)),
2)*(1) you can nest CASE* - CASE in a CASE
CASE WHEN ecovery_flg = 'NONCASH FEE RECEIVED' THEN
CASE WHEN feepaid < FEE THEN ....
END
ENDor
*(2) you can try to rewrite it as one CASE*
CASE WHEN ecovery_flg = 'NONCASH FEE RECEIVED' AND feepaid < FEE THEN...

Help With A Case Statement With Multiple Variables
I apologize if this is the incorrect Forum for this type of question, but it was the closest one that I could find. I'm pretty new with SQL and am stuck on this issue. I have roughly 26 dates that I need to compare to one another. Each date is tied to a step code. I also have a Stop value that is tied directly to the "max date" of the step codes. So, I need to compare 30 dates against one another to 1st - ID the max date; 2nd - ID if the Stop value is correct; 3rd - if the stop value is incorrect, identify what the correct value would be.
At first, this seemed like it wouldn't be that hard. I wrote a query that found the max date for each step code. Then I realized that multiple step codes could have the same date. So, I tried using this case statement, but I did not get the expected results. Is there a more efficient way of getting what I need? This code seems like it's not necessary and probably the source of my issue.
CASE
WHEN FS25.ACTUAL_COMPLETION_DATE > FS.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS1.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS2.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS3.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS4.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS5.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS6.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS7.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS8.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS9.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS10.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS11.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS12.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS13.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS14.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS15.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS16.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS17.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS18.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS19.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS20.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS21.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS22.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS23.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS24.ACTUAL_COMPLETION_DATE AND L.FORECLOSURE_STOP_CODE <= '8' THEN '9'
ELSE 'UH OH'
END AS "CHANGE FC STOP TO"
Any assistance is appreciated!I think Igor pointed out a working solution before.
Applying it at your examples (you missed the operator after STOP_CODE, I assume it =):
CASE
WHEN FS25 = GREATEST(FS25, FS24, FS23) AND STOP_CODE = '9' THEN '9'
ELSE 'UH OH'
END AS 'CHANGE STOP CODE TO'
{code}
Be careful at the second example. You are checking:
{code:sql}
FS25 > FS24 OR FS25 IS NOT NULL AND FS24 IS NULL AND FS25 > FS23
OR
FS25 IS NOT NULL AND FS23 IS NULL AND STOP_CODE = '9'
{code}
Remember that AND has higher priority among operators than OR so if FS25 is greater than FS24 and FS23 the condition will be true even if STOP_CODE is not equal 9.

Creating Multiple INSERT statements with SQL
is there a way to create multiple INSERT staements with SQL .
Example scenario : This is only example but i have lot of data in the real time.
sql : Select Emplid from Table A where Emplid between 100 and 350 will retun me 50 rows . i want to insert those rows into another table.
I am looking for output like below instead of Giving output just as EMPLIDs
Insert into PS_LM_DATA ( EMPLID ) values ( 123 )
Insert into PS_LM_DATA ( EMPLID ) values ( 234 )
Insert into PS_LM_DATA ( EMPLID ) values ( 334 )
and so on....
thanks ,
KaruIf you are inserting into another table, you could use
insert into PS_LM_DATA ( EMPLID )
select Emplid from Table A where Emplid between 100 and 350Example:
SQL> insert into emp2(empno) select empno from emp;
14 rows created.
SQL> insert into emp2(empno) select empno from emp where empno between 7369 and 7788;
8 rows created. -

However, I'm getting the following error:
LINE/COL ERROR
37/6 PLS-00103: Encountered the symbol "WHEN" when expecting one of
the following:
:= . ( % ;
On a second note, can I not have the ELSE structure embedded within the case (currently commented out)?
Thanks very much in advance.

/As VG2 pointed out you were missing some semicolons.
Also, CASE input_post_code was replaced with just CASE since you are doing a searched case.
Also, END at the end of the case statement was replaced with END CASE.
