SQL & PL/SQL :: Split Is A Pipe Line Function To Convert Row As Columns
Jan 31, 2013
In this query split is a pipe line function to convert row(rows stored with , delimited) as columns like below
for ex for below query
SELECT * from TABLE(SPLIT('bbb003,bb004'));
out put is
bbb003
bb004
now i have to apply same function on column,column is storing data with ',' separated.and i have tried like but it's throwing missing expression. how i can use this function on entire column from this table.
SELECT * from TABLE(SPLIT(select candidates FROM ibis.cw_uploads_inprogress ));
I want to use a function in join clause. so i go for pipelined function(using for loop to get record & 1 more loop to fetch in table type variable). i achieved what i required. but problem is it takes much time to fetch data. is there any other approach which returns table records without pipelined function.
We are processing spatial data from another source to display in our GIS environment. The data is a set of multi lines. The gtype is 2006. A typical geometry looks like:
Now, this is not an actual multiline... it's just encoded as a multi line, but if you look at the coordinates you'll see that the end point of the first line is the same as the beginning of the second line (105094.84, 195084.96).
I've used PIPELINED FUNCTION and I've no issues in using this. Just wanted to know is there a way so that I don't need to pipe each row separately and I can pipe a set of rows at once.
Like we use BULK COLLECT INTO to fetch multiple rows at once instead of fetching one row using SELECT INTO.
'Oracle fast parallel data unload into ASCII file(s)' in this blog: URL....I have compiled the code and created the objects and the directory in my DB...But when I execute :
SELECT * FROM TABLE( DATA_UNLOAD( CURSOR( SELECT /*+ PARALLEL(A, 2, 1) */ TABLE_NAME || '|' || COLUMN_NAME || '|' || DATA_TYPE FROM MYTABLE A [code]....
It is supposed to return 2 rows (because of parallel execution), but it just returns 1..Do I have to do something special in order to make parallel pipelined function work
I Want to make a query to select finished goods product in sales having product code greater than 280 but i have face a problem that order by is not working because products column have character code as well as number. how to sort that column.
I have created a function that is used for splitting a comma separated string & give the output in tabular form.here is the function
Here I have used CLOB as my input string will be huge(greater than max limit of varchar2)
CREATE OR REPLACE TYPE SPLIT_TBL_CLOB AS TABLE OF CLOB; CREATE OR REPLACE FUNCTION CSVTOSTRING_CLOB ( P_LIST CLOB, P_DEL VARCHAR2 := ',' ) RETURN SPLIT_TBL_CLOB PIPELINED
[code]....
But here I am facing 2 problems.
1. The function is not accepting a large string & I am getting the error
there are 3 columns as Address1(max data length 80) , Address2(max data length 80), Address3 (max data length 80)..I need to fetch all the three address line with max length of 40 in each columns after concatenate address1,address2,address3
E.g Field data_length Address1 49 Address2 32 Address3 33
now I need to concate all the char and split in 40 char per field i.e. 49+32+33 = 114
Field data_length Address1 40 Address2 40 Address3 24
I tried creating the required view using 'CASE' statement and group by but its returning multiple rows.
select case when PropertyID=1 then VALUE end as Attrib1, case when PropertyID=2 then ValueID end as Attrib2, case when PropertyID=3 then ValueID end as Attrib3 case when PropertyID=4 then ValueID end as Attrib4 from ( select Phone, PropertyID, ValueID,Value from PropertyValue group by Phone, PropertyID, ValueID,Value )
WITH table1 AS -- this table contain a list of column names ( SELECT 11 cid, 'TEK' group_nm, 'TYPE DESC' column_nm FROM dual UNION ALL
[Code].....
i have 3 tables, one that contains name of columns(table1), another one contain number of rows (table2) and the last table contain
the values for columns in table1 for each row in table2.
what i want to do is join all 3 tables and display the output as follow
TYPE DESC NAME P DATE TYPE_PCT ==================================================== Good John 8/21/2010 0.009 BAD Ken 4/11/2010 10.009 Medium Rob 8/1/2010 0.001
as you can see the columns names comes from table1, and the values comes from table3. i want to join these tables so that it display the output above
SELECT LOC_CD, TO_CHAR(DT,'fmMon RRRR'), SUM(QTY) , GROUPING_ID(LOC_CD) FROM WIP WHERE LOC_CD IN (1,2,3,4) GROUP BY ROLLUP(LOC_CD), TO_CHAR(DT,'fmMon RRRR'),TRUNC(DT,'MM') ORDER BY TRUNC(DT,'MM'),LOC_CD
This query result attached
The red coln is the total I want to place it in row-wise
Date loc_1 loc_2 loc_3 loc_4 Total May 2012 4,554 6,644 11,198 June 2012 4,986 5,838 777 11,601 22,799
1) Split values from "INST" Column : suppose 23 2) Find all values from "NUM" column for above splitted value i.e 23 ,
Eg:
For Inst : 23 , It's corresponding "NUM" values are : 1234,1298
3) Save these values into
A table Y : INST, NUM are column names.
INST NUM 23 1234,1298
1) I have a thousand records in Table X , and for all of those records i need to split and save data into Table Y.Hence, I need to do this task with best possible performance.
2) After this whenever a new data comes in Table X, above 'split & save' operation should automatically be called and append corresponding data wherever possible..
create type emp_obj_dtl as OBJECT (ename varchar2(50),mgr NUMBER) create type emp_dtl_obj_typ as TABLE of emp_obj_dtl
Using the these object i have created on function as
CREATE OR REPLACE FUNCTION emp_test_func (peno NUMBER) RETURN emp_dtl_obj_typ AS lv_emp_dtl emp_dtl_obj_typ := emp_dtl_obj_typ (); BEGIN SELECT emp_dtl_obj_typ(emp_obj_dtl (ename, mgr)) INTO lv_emp_dtl FROM emp WHERE empno = peno;
RETURN lv_emp_dtl; END;
Now if i am executing query as
SELECT empno, emp_test_func (empno) emp_dtls FROM emp
Here columns should be created based purchase dates dynamically with respect to quantity. Query out put will be like matrix format. So i feel that PIVOT & SYS_CONNECT_BY_PATH will not serve my requirement.
