I have below Two Strings
Src Id = 1:2:3:4
Src Qty = 2:4:7:9
So I want to Insert into a Table like
Insert into tbl (Src_id,qty) values (1,2);
Insert into tbl (Src_id,qty) values (2,4);
Insert into tbl (Src_id,qty) values (3,7);
and so on for all
So How i can use a loop by using APEX_UTIL.STRING_TO_TABLE or something else to align the Src id and Qty to insert them as single row in a table
You don't need a loop (i.e. PL/SQL); everything can be done in SQL. Here's how:
SQL> with test (src_id, src_qty) as
2 (select '1:2:3:4', '2:4:7:9' from dual)
3 select regexp_substr(src_id, '[^:]+', 1, level) ||','||
4 regexp_substr(src_qty, '[^:]+', 1, level) result
5 from test
6 connect by level <= regexp_count(src_id, ':') + 1;
RESULT
---------------------------------------------------------
1,2
2,4
3,7
4,9
SQL>
I have done the Solution as below
DECLARE
l_src_arr2 APEX_APPLICATION_GLOBAL.VC_ARR2;
l_qty_arr2 APEX_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
l_src_arr2 := APEX_UTIL.STRING_TO_TABLE ('1:2:3:4');
l_qty_arr2 := APEX_UTIL.STRING_TO_TABLE ('2:4:7:9');
FOR i IN 1 .. l_src_arr2.COUNT LOOP
DBMS_OUTPUT.PUT_LINE ('Src = ' || l_src_arr2 (i) || ' qty = ' || l_qty_arr2 (i));
END LOOP;
END;

good morning guys i have a problem with code i work on Health Care and complain code must be checkbox but they ask for Report that contain the treatment code which is gonna appear in database like this 1:15:2:3 etc so i need to calculate each code separate
i have to count until i get ":" then i need to take the number which can be 1 or 2 digit then making inner join with the other table
can anyone help me to fix this function and the problem in the loop and get the number for each one
create or replace function hcc_get_tcd_codes (p_id in number )
return varchar2 is
x number := 0 ;
y number := 0 ;
z number ;
code1 number ;
code_name varchar2(15);
begin
for i in 0 .. x
loop
select length(t.tcd_codes ) into x from hcc_patient_sheet t where t.id = p_id ; --- (9)العدد كامل
select instr(tcd_codes, ':') into y from hcc_patient_sheet t where t.id = p_id ; ---- عدد الكود الاو(3)ل
select instr(tcd_codes, ':')+1 + y into z from hcc_patient_sheet t where t.id = p_id ; --عدد الكود كامل +1
enter code here
i := x -y ;
select substr(t.tcd_codes,z, instr(tcd_codes, ':')-1) into code1
--,select substr(t.tcd_codes, 0, instr(tcd_codes, ':')-1) as code2
from Hcc_Patient_Sheet t
where t.id = 631 ;
select t.alt_name into code_name from hcc_complaint_codes t where t.code = code1 ;
select instr(tcd_codes, ':') into y from hcc_patient_sheet t where t.id = p_id ; ---- عدد الكود الاول
return code_name ;
end loop ;
end;
Often with frequent sounding string processing issues, a wheel has already been invented, and even packaged.
select * from table(apex_string.split('THIS:IS:GREAT',':'));
Partial SUBSTR doesn't seem to be the best option; I'd suggest you to split that colon-separated-values string into row as follows:
SQL> with test (col) as
2 (select '1:15:2:3' from dual)
3 select regexp_substr(col, '[^:]+', 1, level) one_value
4 from test
5 connect by level <= regexp_count(col, ':') + 1;
ONE_VALUE
--------------------------------
1
15
2
3
SQL>
and use such an option in your query; something like this:
select ...
into ...
from some_table t
where t.id in (select regexp_substr(that_string, '[^:]+', 1, level) one_value
from dual
connect by level <= regexp_count(that_string, ':') + 1
);
If it has to be row-by-row, use the above option as a source for the cursor FOR loop, as
for cur_r in (select regexp_substr(that_string, '[^:]+', 1, level) one_value
from dual
connect by level <= regexp_count(that_string, ':') + 1
)
loop
do_something_here
end loop;
I have a query
SELECT originating_timestamp
FROM sys.x$dbgalertext
WHERE message_text LIKE '%Starting up%'
and to_char(ORIGINATING_TIMESTAMP,'DD-MON-YY') = to_char(systimestamp,'DD-MON-YY');
The output in a linux script is as below:
09-OCT-17 04.59.33.758 AM -05:00 09-OCT-17 05.03.22.645 AM -05:00
there are two rows above each starting by date.
I would like to have the output like
09-OCT-17 04.59.33.758 AM -05:00;09-OCT-17 05.03.22.645 AM -05:00
This is just two rows, there can be many more, I would like it so that every row is separated via delimiter.
I have tried few options like
1) using listagg:
select listagg(originating_timestamp,', ') within group(order by originating_timestamp) csv
from sys.x$dbgalertext
WHERE message_text LIKE '%Starting up%'
and to_char(ORIGINATING_TIMESTAMP,'DD-MON-YY') = to_char(systimestamp,'DD-MON-YY');
But this gives error:
ERROR at line 1:
ORA-01489: result of string concatenation is too long
2) using XMLAGG:
SELECT RTRIM(XMLAGG(XMLELEMENT(E,originating_timestamp,';').EXTRACT('//text()') ORDER BY originating_timestamp).GetClobVal(),',') AS LIST
FROM sys.x$dbgalertext
WHERE message_text LIKE '%Starting up%'
and to_char(ORIGINATING_TIMESTAMP,'DD-MON-YY')= to_char(systimestamp,'DD-MON-YY');
But the output is like :
2017-10-09T04:59:33.758-05:00;2017-10-09T05:03:22.645-05:00;
Which is also not correct.
e.g. Select username from dba_users. Suppose there are 10 users, i want those 10 usernames to be separated via delimiter.
Below two anonymous block example which may be helpful to solve your problem :
SET SERVEROUTPUT ON SIZE 1000000
DECLARE
res VARCHAR2(100);
tmp VARCHAR2(100);
BEGIN
FOR i IN 1..10 LOOP
IF i != 10 THEN
select 'a' ||',' into tmp from dual;
ELSE
select 'a' into tmp from dual;
END IF;
res := concat(res,tmp);
END LOOP;
DBMS_OUTPUT.PUT_LINE(res);
END;
/
Second :
SET SERVEROUTPUT ON SIZE 1000000
DECLARE
res VARCHAR2(1000);
tmp VARCHAR2(1000);
BEGIN
FOR i IN 1..10 LOOP
IF i != 10 THEN
select TO_CHAR(sysdate,'DD-MON-YYYYHH24:MI') || ',' into tmp from dual;
ELSE
select TO_CHAR(sysdate,'DD-MON-YYYYHH24:MI') into tmp from dual;
END IF;
res := concat(res,tmp);
END LOOP;
DBMS_OUTPUT.PUT_LINE(res);
END;
/
You should replace my query select with yours and of course the format of date you wanna get and replace comma with your desire character .
To make it working properly i wanna suggest you to create a cursor :
SET SERVEROUTPUT ON SIZE 1000000
DECLARE
res VARCHAR2(100);
tmp VARCHAR2(100);
cont NUMBER;
CURSOR C_1 IS
SELECT to_char(originating_timestamp,'your date format')
originating_timestamp
FROM sys.x$dbgalertext
WHERE message_text LIKE '%Starting up%'
and to_char(ORIGINATING_TIMESTAMP,'DD-MON-YY') = to_char(systimestamp,'DD-MON-YY');
BEGIN
cont := 0;
FOR C_row IN C_1 LOOP
IF cont != C_1%rowcount THEN
tmp := C_row.originating_timestamp ||',';
res := concat(res,tmp);
ELSE
tmp := C_row.originating_timestamp;
res := concat(res,tmp);
END IF;
cont := cont +1;
END LOOP;
DBMS_OUTPUT.PUT_LINE(res);
END;
/
My requirement is to create a procedure or SQL query in which where clause should be created in run time depending on the paramters provided by the user.
Example if user provides data for three columns then where clause should have filter conditions for these three columns only to select the data from database table, like wise if user provides data for 4 columns then where caluse should have 4 columns.
I don't see any very specific solution to your question but it can be done using putting OR in where clause with different set of user input. See below:
Created procedure: Here my employee table has emp_id,name and salary columns. Now am assuming user sometimes passes emp_id and emp_name alone.
CREATE OR REPLACE PROCEDURE dynmc_selec (id NUMBER DEFAULT 0,
name VARCHAR2 DEFAULT 'A',
salary NUMBER DEFAULT 0,
emp_output IN OUT SYS_REFCURSOR)
AS
var VARCHAR2 (100);
BEGIN
--You need to make several combinations in where clause like ( emp_id , emp_name , salary ) OR ( emp_id , emp_name ) OR (emp_name , salary ) and use it in where clause with 'OR'.
--Also its needed that all the columns of the table is in where clause. If user doesnot pass anything then defualt value will be passed.
var :=
'select emp_id from employee where ( emp_id ='
|| id
|| ' and emp_name = '''
|| name
|| ''' ) OR emp_sal = '
|| salary;
DBMS_OUTPUT.put_line (var);
EXECUTE IMMEDIATE var;
OPEN emp_output FOR var;
EXCEPTION
WHEN OTHERS
THEN
NULL;
END;
Calling it:
declare
a SYS_REFCURSOR;
v_emp_id employee.emp_id%type;
begin
--passing emp_id and name only
dynmc_selec(id=>1,name=>'KING',emp_output=>a);
loop
FETCH a INTO v_emp_id;
EXIT WHEN a%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(v_emp_id );
end loop;
end;
Output:
select emp_id from employee where ( emp_id =1 and emp_name = 'KING' ) OR emp_sal = 0
1
select * from test_table
where
(1 = nvl2(:l_date, 0, 1) or created_at > :l_date)
and (1 = nvl2(:l_no, 0,1) or no = :l_no);
With Oracle nvl2 function:
When the parameter l_date is null, then 1 = nvl2(l_date, 0, 1) evaluates to true and the filter by created_at is not taking place.
When the parameter l_date is not null, then 1 = nvl2(l_date, 0, 1) evaluates to false and the filter by created_at is taking place.
The same thing happens with the parameter l_no.
I have some variables that I would like to assign values based on a cursor in PL/SQL.
the variables are variable_1, variable_2, variable_3.
FOR cursor_name IN
(SELECT *
FROM
(select acct_id from dual)
LOOP
//Exit when i > 3
variable_i := acct_id;
i:= i+1;
END LOOP;
Thanks
When you go through a cursor with a FOR loop you get a record with all the fields in the query, in your case the record is named 'cursor_name'. :
FOR cursor_name IN (SELECT acct_id FROM dual) LOOP
//Exit when i > 3
variable_i := cursor_name.acct_id;
i:= i+1;
END LOOP;
We have a table which has three columns in it:
Customer_name, Age_range, Number_of_people.
1 1-5 10
1 5-10 15
We need to return all the number of people in different age ranges as rows of a single query. If we search for customer #1, the query should just return one row:
Header- Age Range (1-5) Age Range (5-10)
10 15
We needed to get all the results in a single row; When I query for customer 1, the result should be only number of people in a single row group by age_range.
What would be the best way to approach this?
You need to manually perform a pivot:
SELECT SUM(CASE WHEN age_range = '5-10'
THEN number_of_people
ELSE NULL END) AS nop5,
SUM(CASE WHEN age_range = '10-15'
THEN number_of_people
ELSE NULL END) AS nop10
FROM customers
WHERE customer_name = 1;
There are easy solutions with 10g and 11g using LISTGAGG, COLLECT, or other capabilities added after 9i but I believe that the following will work in 9i.
Source (http://www.williamrobertson.net/documents/one-row.html)
You will just need to replace deptno with customer_name and ename with Number_of_people
SELECT deptno,
LTRIM(SYS_CONNECT_BY_PATH(ename,','))
FROM ( SELECT deptno,
ename,
ROW_NUMBER() OVER (PARTITION BY deptno ORDER BY ename) -1 AS seq
FROM emp )
WHERE connect_by_isleaf = 1
CONNECT BY seq = PRIOR seq +1 AND deptno = PRIOR deptno
START WITH seq = 1;
DEPTNO CONCATENATED
---------- --------------------------------------------------
10 CLARK,KING,MILLER
20 ADAMS,FORD,JONES,SCOTT,SMITH
30 ALLEN,BLAKE,JAMES,MARTIN,TURNER,WARD
3 rows selected.
This will create a stored FUNCTION which means you can access it at any time.
CREATE OR REPLACE FUNCTION number_of_people(p_customer_name VARCHAR2)
RETURN VARCHAR2
IS
v_number_of_people NUMBER;
v_result VARCHAR2(500);
CURSOR c1
IS
SELECT Number_of_people FROM the_table WHERE Customer_name = p_customer_name;
BEGIN
OPEN c1;
LOOP
FETCH c1 INTO v_number_of_people;
EXIT WHEN c1%NOTFOUND;
v_result := v_result || v_number_of_people || ' ' || CHR(13);
END;
END;
To run it, use:
SELECT number_of_people(1) INTO dual;
Hope this helps, and please let me know if there are any errors, I didn't testrun the function myself.
Just do
select Number_of_people
from table
where Customer_name = 1
Are we missing some detail?
