Find Situations Where Single Unique Value Of Field A Has Both Values Z AND X In B?
Feb 19, 2011
In literal terms, I'm interested in two fields, I'll call them Field A and Field B. I want to find all situations where a single unique value of Field A has both values Z AND X in Field B (not either or, but both together).
To go into some detail -
I need to make a query that finds ONLY occurrences where one employee id has a certain set of values together (without going into specifics, I'll say PermissionA, PermissionB, PermissionC). I can easily make a query that returns all user id's and all permissions belonging to them, and I can use criteria to filter the results to Permission A B and C only so as to exclude other permissions from getting returned (since there are hundreds),
however my objective is to get ONLY results where the same employee ID has all of those permissions (not just any one or two of the three). However, I don't want to have any criteria that limits the employee ID (I want to search all employee id's, and get a list of those with permissions a and b and c, not just any combination thereof, but all of them). I'm currently able to organize the output using a pivot table by employee id > role,
so that I can easily look at each employee and the roles they have, but I want to undertake a project that will involve searching a much larger number of employees (a # that makes it impractical for me to look through the list, I need to have a query that limits the results to the combinations that I'm looking for, as in this example - permission a b and c together).
Personally, I don't need the top value(s), but it would be nice.I was trying a few routes with rownum, and I can get it to pull 1 set of pairs with a where location= condition, but I can't seem to successfully combine the two.
CREATE TABLE prim_tbl (id NUMBER,--- id is not primary key here description VARCHAR2(30));
INSERT ALL INTO prim_tbl VALUES (1,'aad') INTO prim_tbl VALUES (1,'aads') INTO prim_tbl VALUES (2,'bb') INTO prim_tbl VALUES (2,'cc') INTO prim_tbl VALUES (2,'dd') SELECT * FROM dual;
I want to select the ids only one time, i.e my output will have only two rows: one row with id as 1 and other row with id 2 whatever be the description.
desired output sample:
Quote:1, aad 2, bb
I used: select distinct(id),description from prim_tbl;
but it did not give the required result.How can I get it??
Using Oracle 11g, below is the table, partitions, unique and non-unique local index:
CREATE TABLE DOCA( DOCA_ID NUMBER NOT NULL , DOCA_BKG_PAX_ID NUMBER NULL , ROW_PURGE_DATE DATE NULL ,)PARTITION BY RANGE(ROW_PURGE_DATE)INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))( PARTITION P2007 VALUES LESS THAN (TO_DATE('01/01/2008', 'dd/mm/yyyy')), PARTITION P200801 VALUES LESS THAN (TO_DATE('01/02/2008', 'dd/mm/yyyy')),) TABLESPACE T0; ALTER TABLE DOCA ENABLE ROW MOVEMENT;
CREATE UNIQUE INDEX XPKDOCA ON DOCA( DOCA_ID ASC, ROW_PURGE_DATE ASC)LOCALREVERSE TABLESPACE I0; ALTER TABLE DOCA ADD CONSTRAINT XPKDOCA PRIMARY KEY (DOCA_ID); CREATE INDEX XFKDOCA_DOCA_BKG_PAX_ID ON DOCA( DOCA_BKG_PAX_ID ASC)LOCALREVERSETABLESPACE I0;
I would like to know the difference between the performance of the unique and non-unique local indexes?.
Create a function which will indicate if a given record in a table is unique or not. Unique means the data is occurring only once in the entire table.
Function should be in this signature
function IS_UNIQUE (tableName in varchar2,tableAttribute in varchar2) return number ..... begin //logic to check if given data is unique return 0; //return 0 if data is unique else return 1; //return 1 if data is duplicate end;
Once I run this query
select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=0
All records of attribute1 which are unique need to be fetched. Similarly, select attribute1 from table1 where IS_UNIQUE(table1,attribute1)=1 should return all records of attribute1 which are duplicates.
Objective: I need to compile a final string by concatinating the unique values from different strings.
Here is the script to create tables and data.
Create table temp_acronyms(id number, acronym varchar2(30); insert into temp_acronyms values(1, 'ABC'); insert into temp_acronyms values(2, 'DEC//NOFO'); insert into temp_acronyms values(3, 'CBK//FO TO USA'); insert into temp_acronyms values(4, 'DEC//NO ENTRY'); insert into temp_acronyms values(5, 'ABC//NOFO');
COMMIT;
select * from temp_acronyms;
ID ACRONYM --- -------- 1 ABC 2 DEC//NOFO 3 CBK//FO TO USA 4 DEC//NO ENTRY 5 ABC//NOFO
I need to store all the unique strings from the acronyms for id's 1,2, 3, 4 and 5 into a variable. doesn't matter even if it is through database procedure.
I have a table which stores customer ID and price lists assigned to those customers. Each price list can have multiple customers assigned to them. So for example
Customer APrice_List1 Customer BPrice_List1 Customer C Price_List2 Customer D Price_List3
Now I am trying to write a SQL statement to return just pricelists which contain just ONE customer (so in the above example would just return Price_list2 and Price_List3).
We are using the function dbms_utility.get_hash_value to create a unique identifier, the hash is created based on statement of creating an index. We see that for a different statement is being generated the same value, which in this cause errors because this value must be unique.
The Hash is to be calculated as follows HASH_VALUE = dbms_utility.get_hash_value (sql_text, a 10000)
We are using the correct the hash function or should we use another way to generate unique values?
I don't want to generate row_number for unique values 'C' and 'E' in below query.
SELECT NAME, ROW_NUMBER() OVER (PARTITION BY NAME ORDER BY NAME) FROM (SELECT 'A' NAME FROM DUAL UNION ALL SELECT 'A' FROM DUAL UNION ALL SELECT 'A' FROM DUAL
[code].....
Means row_number should be NULL for unique values.
A B ---------- ---------------------------------------- 1 Hello 2 Hello 3 No Hello 4 No Hello 5 Hello 6 Hello 7 Hello
I want to print the output of this table as -->>
A B ---------- ---------------------------------------- 1 2 Hello 3 4 No Hello 5 6 7 Hello
To make it more clear, I just want that whenever the value f column "B" changes then only its value should be printed, else it should be NULL. And if "B" has same value for all the records then the value of "B" should be printed at the last.
I am facing a problem in leave_form report! want to show employee's previous leaves detail (leavedate,leavetype), i don't want to show leavetype 'PPP' repeating frame type is Across/Down, there are 22 records of leavetype 'PPP' and one record of leavetype 'CL'
problem is report is showing 22 records of leavetype 'CL' of same leavedate!
i want that report should show the actual leavedate and leavetype records.using 9i database 6i developer server2003
For leavetype
FUNCTION Cf_1formula RETURN CHAR IS v_leavetype CHAR(40); BEGIN SELECT LT.description INTO v_leavetype FROM hrm_attendance L, hrm_leavetype LT, hrm_employees E [code]....
In my form i have a multi record block which is based on a table in which i am performing insertion, deletion, updation.
My requirement is as below,
While saving a records i want to check distinct value of specific item can not be greater than some value say 2. Then only my records should be saved. I am planning to populate those values in a collection table type and take the distinct values from it. How to populate record values in a collection table type.
Consider below is a multi record block rows, i want to hide "23". Is it possible using Set_Item_Instance_Property or any other built-in is there in oracle forms to hide a single row field in a multi record block.
I have developed one report but need one formatting suggestion. There is one field called "DESCRIPTION", I want the value of this field to be displayed in a single line. Now the big values are wrapped into multiple line.
Now,
DISPLAY ---------------- This is a Oracle Report.
I want, DISPLAY ------------------------ This is a Oracle Report.
I know I can add a check constraint for m,t,w,r,f,s,u How can I add a constraint that will allow any combination of the above. For example it would allow m or mf, or mwf Someone said it could be done with trim but I can not figure it out.
I have a table in schema with a BLOB field. I store employee's picture in this field. Fields in this table are emp_id (number) emp_name (varchar2) and emp_photo (BLOB). I want to ask if there is a way in pl / sql that i could empty this BLOB field to null or reset this field so that user can change the saved photo graph and save another one.
what i am looking for is something like
alter table employee set emp_photo = empty_blob() or alter table employee set emp_photo = null
Updating multiple ROWS with different values using single statement. Requirement is to update one column in a table with the values in the other table.
Say we have 3 tables, CORPORATION,CORPORATE PROFILE and MEMBER.
Each MEMBER has CORPORATE PROFILE which in turn is associated with CORPORATION. Now I need to update MEMBER table with CORPORATION identifier for members who belong to corporations with identifiers say 'ABC' and 'DEF'.
MEMBER table contains column 'CORPIDENTIFIER '. CORPORATEPROFILE table contains MEMBERID and CORPORATIONID,this will associate a member with the corporation. CORPORATION table contains ID and CORPIDENTIFIER.
Using the below query I am getting error,ORA-01427:single-row subquery returns more than one row
UPDATE MEMBER M SET M.CORPIDENTIFIER= (SELECT A.IDENTIFIER FROM CORPORATION A,CORPORATEPROFILE B WHERE B.CORPORATIONID=A.ID AND B.MEMBERID=M.ID AND (A.IDENTIFIER LIKE 'ABC' OR A.IDENTIFIER LIKE 'DEF'))
Sub query in the above query returns multiple rows and hence it is throwing the error.More than one members are associated with Corporations ABC and DEF. Is there any way possible to update all the rows in single query with out iterating the result set of sub query.
I have two tables eim_asset and eim_asset1.I want to update the table eim_asset1 using the following update SQL (Or Logic)
update eim_asset1 set emp_emp_login = (select login from s_user where row_id in (select row_id from s_emp_per where row_id in (select pr_emp_id from s_postn where row_id in (select position_id from s_accnt_postn where ou_ext_id in (select row_id from s_org_ext where row_id in (select owner_accnt_id from s_asset where owner_accnt_id is not null)))))
It gives me the ORA error : ORA-01427:single-row subquery returns more than one row.know why I am getting it, because of the one-to-many relationship between owner accounts and their assets.
I have 2 blocks,in one i insert student_id and when i click on the button i should get all his courses in the other block...
BUT.. when the student has more than 1 course I get this:
when button pressed trigger raised unhandled exception ORA-01422
Here is the button
begin
select TEST_STUDENT_INFO.stud_name,TEST_STUD_CRSE_DETAIL.crse_no, TEST_COURSES.crse_name,TEST_STUD_CRSE_DETAIL.crse_type,TEST_STUD_CRSE_DETAIL.crse_type_desc, TEST_COURSES.crse_time INTO :stud_name,:crse_no1,:crse_name,:crse_type1,:crse_type_desc1,:crse_time from TEST_STUDENT_INFO,TEST_COURSES,TEST_STUD_CRSE_DETAIL where (TEST_STUD_CRSE_DETAIL.STUD_ID =:TEST_STUD_CRSE_REG.STUD_ID) and (TEST_STUDENT_INFO.STUD_ID =:TEST_STUD_CRSE_REG.STUD_ID) and (TEST_COURSES.CRSE_NO = TEST_STUD_CRSE_DETAIL.CRSE_NO) and (TEST_STUD_CRSE_DETAIL.CRSE_TYPE = TEST_COURSES.CRSE_TYPE);
end;
but if the student has ONLY ONE course it WORKS FINE!
