Set operators in PLSQL

Hi All,
Can we use set operators in PLSQL. I hope we can not use it in PLSQL. But just wanted to check with you all.
Begin
select 1 into n from dual
union
select 2 into n from dual;
end;
Thanks

Not using that syntax you won't in PL/SQL as it's just wrong.
As you're querying multiple rows you'd have to either loop or collect it in to a collection e.g.
SQL> declare
2    type aNums is table of number;
3    vNums aNums;
4 Begin
5    select n
6      bulk collect into vNums
7    from
8      (
9      select 1 as n from dual
10      union
11      select 2 from dual
12      );
13 end;

What is use of set operators in OBIEE

Hi Guys,
Colud you please tell me what is main use of Set Operators (Intersection,Union,Union all)in OBIEE.
Is it mandatory to use them in reports?
Pls tell me.
Regards,
siva

Hi,
What scenario we are using set operators.
For Eg.
Col 1 is having values:
A
B
C
Col 2 is having values:
1
2
3
I have to create a new column in answers having values
A
B
C
1
2
3
solution:
You can use SET operators in OBIEE and it's really easy to set it in answers section. So create one request and then add other similar request to it by using UNION operator.
or
we can use case statement also.
2. Is it mandatory to use them in reports?
Normal reports not mandatory.
Hope it helps.
Thanks,

Set Operators - Clarification needed

This is my query. I am executing this in HR Schema Oracle 11g.
SELECT HIRE_DATE, EMPLOYEE_ID, to_char(null) FROM EMPLOYEES WHERE LAST_NAME='Taylor'
UNION ALL
SELECT SYSDATE, TO_CHAR(NULL), 1+1 FROM DUALIt gives ORA-01790: expression must have same datatype as corresponding expression error. What data type is mismatching here? I don't seem to understand. HIRE_DATE and SYSDATE - DATE data type. Is something wring with my other two columns? I read that TO_CHAR(NULL) can be used for filling missing values. That's why I tried this way.
Any guidance, please?

Hi,
whenever you use set operators there has to be ont to one datatype correspondance of the columns you define in all the select statements.
Here the first select statement's employee_id number is conflicting with to_char(null) and to_char(null) is conflicting with 1+1.
Hence try out this
SELECT HIREDATE, Empno, to_char(null) FROM EMP WHERE ename='Taylor'
UNION ALL
SELECT SYSDATE, 1+1,TO_CHAR(NULL) FROM DUAL
or use
SELECT HIRE_DATE, EMPLOYEE_ID, to_NUMBER(null) FROM EMPLOYEE WHERE LAST_NAME='Taylor'
UNION ALL
SELECT SYSDATE, TO_NUMBER(NULL), 1+1 FROM DUAL

Set operators over ore.frame

Is there a way to make set operators work with ore.objects without ore.pull?
EXAMPLE:
> df1 <- data.frame(ID=c(1:3),A=rep(1,3))
> df2 <- data.frame(ID=c(2:4),B=rep(1,3))
> class(df1)
[1] "data.frame"
> # Union
> union(df1$ID,df2$ID)
[1] 1 2 3 4
> # Minus
> setdiff(df1$ID,df2$ID)
[1] 1
> #Intersect
> intersect(df1$ID,df2$ID)
[1] 2 3
> #-------------------------------------------------
> of1 <- ore.push(df1)
> of2 <- ore.push(df2)
> class(of1)
[1] "ore.frame"
attr(,"package")
[1] "OREbase"
> # Union
> union(of1$ID,of2$ID)
integer(0)
> # Minus
> setdiff(of1$ID,of2$ID)
integer(0)
> #Intersect
> intersect(of1$ID,of2$ID)
integer(0)
> #-------------------------------------------------
> vec1 <- ore.push(df1$ID)
> vec2 <- ore.push(df2$ID)
> class(vec1)
[1] "ore.integer"
attr(,"package")
[1] "OREbase"
> union(vec1,vec2)
integer(0)

Many of the commonly used base R functions are overloaded in the Oracle R Enterprise transparency layer to work with ore.frame objects. These functions are located in the OREbase and OREstats packages.
For example, to get the union, use merge, as it has been overloaded to operate on ore.frame objects:
R> find("merge")
[1] "package:OREbase" "package:base"
merge(x = of1, y = df2, all = TRUE)
R> merge(x = of1, y = of2, all = TRUE)
ID A B
1|NA 1 1 NA
2|1   2 1 1
3|2   3 1 1
NA|3 4 NA 1
to subtract:
R> find("Arith")
[1] "package:OREbase" "package:methods"
of1$A - of2$B
R> of1$A - of2$B
[1] 0 0 0
There is no need to pull the data if the function is overloaded to work with ore.frame objects. More examples can be found in the ORE 1.4 Training Materials: Oracle R Enterprise 1.4 Transparency Layer: http://www.oracle.com/technetwork/database/database-technologies/r/r-enterprise/learnmore/ore-1-4-transparency-layer-215…
You can view the functions in the OREbase and OREstats packages by typing:
ls("package:OREbase")
ls("package:OREstats")

SELECTing records from two tables. Set Operators, CASE, DECODE, ...

Hi all,
I have two tables:
CRETE TABLE T1 (T1_COL1 NUMBER, T1_COL2 NUMBER)
CRETE TABLE T2 (T2_COL1 NUMBER, T2_COL2 NUMBER)
T1 may or may not have records. T2 always has records. There are two scenarios.
Scenario 1:
=======
SELECT * FROM T1 returns five rows, and SELECT * FROM T2 returns 10 rows.
Now I need the five rows from T1.
Scenario 2:
=======
SELECT * FROM T1 returns zero rows, and SELECT * FROM T2 returns 10 rows.
Now I need the 10 rows from T2.
In other words, if records present in T1, I need them all. If not, I need records from T2.
There are no common columns (for joins).
Now need a single query to achive this. I tried set operators, CASE and DECODE. But I'm unable to solve it.
Please help. Thanks in advance.

Is there any other way, which is simpler, without using RANK?That's the simplest option I can think of. You could also do something like

SET OPERATORS IN ABAP

Hi Friends,
I want to compare a variable has any of the 25 stored values in internal table or any variable?

Hi,
Set Operations Using Bit Sequences
If you have a set of m elements, you can represent any subset as a sequence of bits. If the nth element of the set is present in a subset, the n th bit is set to 1, otherwise, it is set to 0. The universal set therefore contains no zeros.
In ABAP, you can represent a set of m elements using a field with type X and length of at least m/8. To include a member of the universal set in a set, use the SET BIT statement. To check which members of the universal set are included in a particular set, use the GET BIT statement. You can use bit operations for the following set operations:
Set operation
Bit operation
Intersection
BIT-AND
Union
BIT-OR
Symmetrical difference
BIT-XOR
You can also use the O operator when comparing bit sequences to determine whether a particular set is a subset of another.

DO 32 TIMES.

    IF BIT = 1.

This produces the following output list:
AA   NEWYORK
AA   SANFRANSISCO
AZ    ROME
AZ    ROME
AZ    TOKYO
AZ    ROME
DL    NEWYORK
DL    SANFRANSISCO
The program uses four hexadecimal fields with length 4 - FRANKFURT, FRISCO, INTERSECT, and UNION. Each of these fields can represent a set of up to 32 elements. The basic set is the set of all airlines from database table SCARR. Each bit of the corresponding bit sequences representes one airline. To provide an index, the external index table CARRIER is created and filled with the airline codes from table SCARR. It is then possible to identify an airline using the internal index of table CARRIER.
In the SELECT loop for database table SPFLI, the corresponding bit for the airline is set either in the FRANKFURT field or the FRISCO field, depending on the departure city. The line number SY-TABIX is determined using a READ statement in which no fields are transported.
The intersection and union of FRANKFURT and FRISCO are constructed using the bit operations BIT-AND and BIT-OR.
The bits in INTERSECT and UNION are read one by one and evaluated in two DO loops. For each position in the fields with the value 1, a READ statement retrieves the airline code from the table CARRIER.

How to set an Application Item from PL/SQL

I am attempting to set an Application Item
After login to my app, I want to retrieve a row from my SETTINGS table and populate some Application Items with the settings information so that I can
display some of that settings information on every page.
Just to start, I created one Application Item named F106_YEAR
I then created a Shared Components Application Process which executes on New Session: After Authentication
I created this process as an Anynomous PL/SQL block.
declare
aucyr varchar(4);
begin
select year into auctyr
from settings;
:F106_YEAR := aucyr;
end;
I've tried a couple of other Syntax tricks attempting to reference the Application Item F106_YEAR from within PL/SQL (like V('F106_YEAR') but nothing seems to be working.
I'm sure that I am missing something simple. Can someone tell me how to set an Application Item from PL/SQL?
Thanks in advance.

I'm still doing something wrong because this is not working for me.
I've tried both of the following versions as an Application Process set to run on New Session after Authentication:
declare
auction_year varchar(4);
begin
select year into auction_year
from PBUUC.SETTINGS where rownum < 2;
:F106_AUCTION_YEAR:=auction_year;
end;
and I also tried:
declare
auction_year varchar(4);
begin
select year into auction_year
from PBUUC.SETTINGS where rownum < 2;
APEX_UTIL.SET_SESSION_STATE (p_name, p_value);
end;
F106_YEAR is a global Item (shared components).
The select statement works just fine in SQL*PLUS so I know that it is correct.
If I run the debugger and log into the application, here is the output. Shouldn't I see my Application Process get called if it is set to run on New Session after Validation?

Compilation error when used SET or MULTISET operator on nested tables

Dear All,
I am getting Compilation error when used SET or MULTISET operator on nested tables inside a procedure.
This is working fine in other DB installations of 10g but does not work in another 10g DB.
it says "wrong number of parameter or datatype used in SET"
Can any one suggest what went wrong here?
Thanks in advance.

Hi,
Thanks for ur reply...
Since MULTISET and SET operators are the new additions in base 10g release for manipulation of nested tables data, I am surprised that same is working in similar 5 DBs installations with 10.2.0.1.0 version, but does not work in the sixth.
SET and MULTISET operators are used inside the PL/SQL procedure which is getting compiled in the above mentioned 5 DBs but not in sixth DB.
it gives
On line: 3112
PLS-00306: wrong number or types of arguments in call to 'SET'
Hope this clarifies the issue...

executeQuery();
When executing the page, its value shows to be "現預金".
And I used String receipt_type = (String)oaRow.getAttribute("ReceiptType"); in AMImpl, its value is "現預金".
But when I execute above sql in pl/sql developer, its value is null.
I am really confused with this.
How could I get the whole running sql statement, and know why my issue is like this? It's very urgent, Thanks!

This Query is Org Specific.(As this query using Ord_id attribute to fetch out row.)
you need to set org_id at PLSQL Developer or Toad Level.

Insert Longraw data type

If at all possible use a BLOB instead of along raw and your work will be much easier.
About the only things you can do with LONG and LONG RAW are inserts and selects, and those sometimes with difficulty. If you check the documentation or even do a web search you should find a long list of what you can't do, including but not limited to
* use the type in WHERE clauses
* modify the type with any function
* use the query with set operators (UNION, etc.)
Use the newer LOB. Your 10g database will allow this.

If at all possible use a BLOB instead of along raw and your work will be much easier.
About the only things you can do with LONG and LONG RAW are inserts and selects, and those sometimes with difficulty. If you check the documentation or even do a web search you should find a long list of what you can't do, including but not limited to
* use the type in WHERE clauses
* modify the type with any function
* use the query with set operators (UNION, etc.)
Use the newer LOB. Your 10g database will allow this.

Oops! 10g docs say you can update a LONG [RAW]. Not sure I want to ...
