Passing Ref Cursor
Oct 14, 2010We receive hand punches (clock data) every day. Normally a person badges in(hand punch) which creates a row in the clock_tran_processed table. The information from that hand punch is the employee id (emp_id) the date hand punch occurred and a work_summary id (wrks_id). At the end of the day, the employee badges out (hand punch out) and another entry in the clock_tran_processed table is created. The new row will have the emp_id (employee name), date the hand punch occurred and the same work summary id from the morning.
Normally hand punches should occur in pairs. One in, one out... or one in, out for lunch, in for lunch, out for day. I am seeing intervals of three and five. Meaning the employee clocked in twice and out once, or in once and out twice. This shouldn't happen.
I am writing a report that will show number of clocks per for all employees that have three(3) or five(5) clock entries.I wrote a ref cursor that gives all the employees that have a count of 3 or 5 and the employee id (emp_id). I need to pass that employee id to another query that will then get me the dates of the clocks.Here is the ref cursor thus far (I am printing those with a count of 3 and 5).
CODEDECLARE
TYPE ClockTran_Refcur IS REF CURSOR;
ClockTran_cur ClockTran_Refcur;
NumClock_num number :=0;
NumClock_name clock_tran_processed.emp_id%TYPE;
[code]...
How do I pass that variable to the get the clktranpro_time's? I am using "Easy Oracle PL/SQL Programming" but I am not seeing this type of example(pgs 140-148).
SQL & PL/SQL :: Passing Value From One Cursor To Other One

SQL & PL/SQL :: Cursor FOR Loop?
Jun 15, 2012I am an experienced SAS programmer jumping into PL/SQL for the first time and have already encountered a problem.Let's assume I have 7 records (shown below). (In reality, I have millions of records, but the concept's the same.) The Value field is only populated when it changes. Therefore, I am forced to "fill in the gaps" as I read the data file. It's fairly straightforward. I carry the value foward one record at a time, using it if the Value field in not populated. The ANSWER I want is also shown.
In reading through a PL/SQL book, I realized that only 2 chapters are relevant to what I do. My guess is this solution involves cursors; probably a Cursor FOR loop,

SQL & PL/SQL :: Passing Partition Name In A Cursor

Seems it's not able to identify R.PARTITION_NAME in update statement. Are you aware whether we can partition name like this if we need to update based on partition names in a cursor.
My cursor code is:
DECLARE

Loop Inside Cursor
Sep 11, 2012I have a cursor returning some value.
for each value returned by the cursor i need to traverse through 31 rows(1 row per day * no of days in the month).
E.g. if cursor returns service_name as xyz then for xyz there can be 31 rows(service may not be used on some days)
I need to go to all of them and take some values and move them to a flat file. how should that be done?

SQL & PL/SQL :: Can FOR Not Be Used To Loop Through Records Of A Ref Cursor
Jul 1, 2011I wrote the following block :
set serveroutput on
declare

open cur for 'select * from employees where rownum<:a' using 4;

It gave errors if we execute is as such, but worked when I commented out the for loop and instead de-commented the simple loop. Does that mean that FOR cannot be used to loop through the records of a ref cursor ?
SQL & PL/SQL :: SELECT From Within A CURSOR LOOP
Nov 19, 2010I am not an Oracle programmer but I have been given a task to produce a number of Text files from an Oracle table based on a selection from the table itself.The table consists of many records with a currency code and I need to extract the data into named files based on the currency code.My first idea was to use Cursors and try a select statement matching on the returned value of the cursor but no Joy I can't make it work - perhaps I need to take a new approach.

SQL & PL/SQL :: Find Previous Cursor Loop Value
Dec 15, 2011I take a select into a cursor and process it record by record.I have to do sum based on a column and display row by row by using dbms_output.put_line .... So the sum has to happen based on a column. Based on the column value i need to display the cumulative sum as well.
Example:-
col1 col2 amount
DL AADD 25
DL BBCC 10
DL BBRR 15
Sum value for DL ----- 50
TX ADED 20
TX EDWW 60
Sum value for TX ----- 80
All the above data should be displayed using DBMS_OUTPUT.PUT_LINE in a pl/sql code. I use cursor to take the values from the table but the problem i face is .... I am not able to display the sum based in the col1 values.
Since i use the cursor .. i took the col1 values in to a variable and checked every time
old_variable = new_variable
if yes then continue the sum
else
display the sum value.
once i get the above check satisfied i am loosing a new col1 row in the check. The next loop only run for the new col1 values -1( which is used in the check loop).So is there any better way to get the solution or is there a facility to store the previous loop values in a cursor ? so that i dont have to loose that one row of data.
I am not able to come up with proper loop so which can identify that the col1 has changed and you have to display the sum value.
SQL & PL/SQL :: How To Exit From For Loop On Cursor Correctly

Dec 26, 2012 the problem we are facing is that we are having some problems with names in a filed which are not letters but strange symbols inserted by a webservice which by the way has been corrected, but we have the discrepancy on out DB, so I've decided to write a PL/SQL procedure to correct them.
Here is the example of an incorrect record.
4047254| STEVE; ROVINSON (THE INCORRECT SYMBOL IS CHR(32), I do not know why the forum doesn't show it)
So, if you look there's a symbol that is not interpreted by the DB and my original idea was to extract them and correct then with another procedure. I have originally wrote a procedure with the logic if there's a symbol that is not beween currect letters (from A to Z including semicolon (;)) extract them and that's it. So, the big question is, How I transfer the control from the second loop to the cursor loop in order to analice the next record.
here is the code which hasn't been completed yet.
DECLARE
CURSOR get_nombre IS
SELECT CNTA_NOM_ABRV

Feb 17, 2012I have a table of 3 columns:

I insert rows into it:
SQL> --fill it with data:

1 row created.
SQL> insert into a(key1 , key2) values (1 , 5);
[code]...
i want to perform a logic by which:for every distinct value of key1 - values of key2 will be checked in all records holding that particular key1 value, and update the key3 field to 'inactive' where the key2 value for that particular key1 is the highest in number.
i've found out that i could do it by an SQL statement:
update a
set key3 = 'inactive'
where key2 = (
select max(key2)
from a a2 where a2.key1=a.key1
);
however I wanted to use the cursor to "load" the max key2 values FOR EACH distinct key1 value exists in the table,and do the same thing as the update statement above WITH A CURSOR,So tried and wrote the following:
SQL> create or replace procedure proc1
2 IS
3
4
5 var1 a.key1%type;

unfortunately, it works only for one row, and i don't understand what's wrong, I executed, and checked what has changed:

SQL & PL/SQL :: How To Loop Through Nested Cursors Based On Value From 1st Cursor
Jul 21, 2011I loop through the 1st cursor (account_csr), while in the 1st csr loop, based on some conditions being true, I want to loop through a 2nd cursor (acctper_csr) but I only want to retrieve data/rows in the 2nd cursor where the account_id column in 1st cursor = account_id column in the 2nd cursor. This will enable me to pull all the account_periods for each account I loop through in the first cursor.
I have attempted several different ways and cannot make this work. Thought I could somehow define a variable and store the account_id from 1st cursor and use on the 'where' clause in the 2nd cursor definition. Have not been able to make this work successfully.
Following is the sample of my

SQL & PL/SQL :: Choose Explicit Cursor To Loop Through At Runtime?
