SQL & PL/SQL :: Create A String With Distinct Values
Aug 11, 2010
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production
"CORE 11.1.0.6.0 Production"
I have a cursor, whose sql is returning seven rows with these values:
9
4
4
9
7
9
4
i open cursor and fetch these values into variable as shown
OPEN id_search FOR l_sql_stmt;
LOOP
FETCH id_search INTO l_eve_id;
if l_eve_id != l_eve_id_prev then
l_eve_id_str := l_eve_id_str || ' , ' ||l_eve_id ;
[code].......
but i want only the distinct values in l_eve_id_str , i.e.,
l_eve_id_str := 9,4,7
What this code is doing is creating a string with all the values
l_eve_id_str := 9,4,4,9,7,9,4
So each Level(L1 ..L4) has zero or many child levels which further has more levels.With out using PL/SQL how can we write a Select query to give me a distinct of all children, all the way to the lowest level (L4).Example: give me all the children where L1 = 3.Result: 31, 32, 33, 311, 322, 333, 3111, 3222, 3333Is it possible to write such a query or am I asking too much logic out of a select and should go with PL/SQL.
I need to write a query in plsql to select records for first 3 distinct values of a single column (below example, ID )and all the rows for next 3 distinct values of the column and so on till the end of count of distinct values of a column.
eg: ID name age 1 abc 10 1 def 20 2 ghi 10 2 jkl 20 2 mno 60 3 pqr 10 4 rst 10 4 tuv 10 5 vwx 10 6 xyz 10 6 hij 10 7 lmn 10 . . . so on... (till some count) Result should be Query 1 should result ---> ID name age 1 abc 10 1 def 20 2 ghi 10 2 jkl 20 2 mno 60 3 pqr 10
query 2 should result --> 4 rst 10 4 tuv 10 5 vwx 10 6 xyz 10 6 hij 10
query 3 should result --> 7 lmn 10 . . 9 .. .. so on..
Productcode Productname Quantity AF Ade Fgh 100 LO Ldo Ope 50 SK Ske Kro 47 ....
There may be any number of records in the table. Now I need to print distinct products in different columns such as.
AF LO SK 100 50 47
There may be any number of products...I need to print all those products as different columns as shown above. How to write the Stored procedure for this?
Sample DateWITH DATA AS ( SELECT 'AAAXXXX IO BLUEEXPRESS' LIST FROM dual UNION ALL SELECT 'BLUEEXPRESS AAAXXXX IO BLUEEXPRESS' FROM dual UNION ALL SELECT 'DDDDD BLUEEXPRESS AAAXXXX' FROM dual UNION ALL SELECT 'DDDDD DDDDD AAAXXXX' FROM dual UNION ALL SELECT 'DDDDD BLUEEXPRESS AAAXXXX NO CARBON' FROM dual UNION ALL SELECT 'NO CARBON [code]....
The above result depends on the following rules:
- Replace BLUEEXPRESS into BEXPRESS - Remove the term NO CARBON (See row no 6) - Reduce all multiple space into single space (see last record).
So far I create separated queries for replacing BLUEEXPRESS into BEXPRESS and replace NOCARBON term but I don't know how to do it in a single shot as well as stuck on scenario to remove multiple spaces and put single space.
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 problem with Between clause used in where statement to compare two string variable.
Query is like this,
select item_code, item_deacrption from itm_master, invoce_det where im_code = item_code AND invd_item_number BETWEEN (:startNum) AND (:endNum)
Here invd_item_number is a DB field and is of type varchar2(41), and (:startNum),(:endNum) are of same type.
now invd_item_number has one value '001003002001' if we give :startNum = '001003001002' and :endNum = '001003004006'
:startNum and :endNum is composed of separate field values (ie, 1st 3 character shows color code, next 3 for catagory, next 3 for size etc). These codes are entered separately and are combined at run time.
it is still fetching the invd_item_number with value '001003002001'. (the last set of character(type code) in the :startNum is greater than invd_item_number's type code value. But it is smaller than the previous code (size code), that's why it is fetching).
But how can i get around this as i don't need that value to be fetched.
How do i split a string based on a space. And then create a view with three columns of that split string.
For example if i have a table with Full name as a column how do i split that string and create a view with firstname, middlename, lastname as column names with the split string as data.
select profilename from PROFILE where user_data like '%DATE_RULE!115%';
Output will be "Test A".Now, this is just a single value from RULES table used to find the data of PROFILE table.I will have to run the query on multiple values of RULES tables to find records containing a string format of sort "DATE_RULE!<rule_no>". How to search on WILD CARDs like these?
I need to remove duplicate values from concatenated long string of state codes(comma separated). Ex: 'VA,VA,PA,PA,CT,NJ,CT,VA'. I tried following query and did not get required out put.
select regexp_replace('VA,VA,PA,PA,CT,NJ,CT,VA,CT,PA,VA,CT','([^,]*)(,1)+($|,)', '13') new_str from dual;
Define Meta-character's format in regular expression to get desired result. Out put required: VA,PA,CT,NJ (with out any duplicates).
We have generated a fancy custom interactive report, in which the columns of string type, but can hold string, numeric or date values. However the type of values are uniform for a particular column. The end users wants to use the numerical values for generating charts, but, being a string column (though the data is numeric), it throws an error and they could not generate the chart. Is there any way to make use of this string column type numerical data for generating chart?
A computation after submit pl/sql function process to trim off the first part of the string (CQ..) within the list manager values. Support for example the list manager contains values such as
The computation process should trim off the first part(CQ..) and should return the list manager value as SAMPLE1..TEST1SAMPLE2..TEST2SAMPLE1..TEST2 Oracle APEX 4.0.2 is the version and Oracle 10g r2 is the database.
i have a table students create table students (name varchar2(10),rolno number(10),sub1mark number(10),sub2mark number(10),total number(10),percentage number(10),status varchar2(10))
i am go to create trigger on students after entering the values of name,rolno,sub1mark,sub2mark the values of total & percentage come automatically .trigger is
CREATE OR REPLACE TRIGGER UCSETH.students_comm_trig BEFORE INSERT ON UCSETH.STUDENTs FOR EACH ROW BEGIN set NEW.total = new.sub1mark+new.sub2mark; set new.percentage=new.total/2;
