SQL & PL/SQL :: Get Number Of Records (not A Simple Count())
Mar 4, 2010
using the sql statement in SQL server. I noticed some of the sql syntax are different. My sql statement is as below;
---Select fieldA, Sum(fieldB+fieldC) as fieldD, fieldE, fieldF from TableA group by fieldA, fieldE, fieldF ---
the output will be as below;
fieldA fieldD fieldE fieldF
------ ------------- ------ ------
fieldA fieldB+fieldC fieldE fieldF
However, I need to have the total of no of records displayed for the sql statement and I need it in one sql statement with the one above so that I can display the total no of records along with the information for each field.

I have written the following PL/SQL procedure to delete the records and count the number of records has been deleted.
CREATE OR REPLACE PROCEDURE Del_emp IS
del_records NUMBER:=0;
BEGIN
DELETE
FROM candidate c
WHERE empid in
(select c.empid
from employee e,
candidate c
where e.empid = c.empid
and e.emp_stat = 'TERMINATED'
);

I am using Oracle 11g Release 11.2.0.1.0
OS: windows
I am taking an example of EMP table in a scott schema.
EMP_1 is also a same structure of EMP.
Here is the Insert statement used.(i might get where clauses etc in the real scenario i am taking a simple example here)
INSERT INTO SCOTT.EMP_1(JOB,ENAME,EMPNO) SELECT JOB,ENAME,EMPNO FROM SCOTT.EMP
table EMP is having around 25 million records.
i would like to do a commit after every 1000 records. as my redo log is getting full if i use a single commit at the end.
Quote:pls note: Increasing of redo log is not possible as of now
is there anyway i can acheive this without cursor bulk collect.

One of the tables is having
SQL> select count(1) from item_list;
COUNT(1)
----------
14356529
To fetch the count using the above query , it takes 6 mins. There are no other processes running in the DB. The fragmentation % on this table is showing 16.3%
I tried finding the fragmentation using the below query.
select table_name,
round((blocks*8),2) "table size kb",
round((num_rows*avg_row_len/1024),2) "actual data in table kb",
round((blocks*8),2)- round((num_rows*avg_row_len/1024),2) "wasted space kb",
((round((blocks*8),2)- round((num_rows*avg_row_len/1024),2)) / (round((blocks*8),2)) ) *100 "percent fragmented"
from dba_tables
where table_name like ITEM_LIST%'
and owner = 'TEST_USR'
and blocks != 0
order by 4 desc
TABLE_NAME table size kb actual data in table kb
------------------------------ ------------- -----------------------
wasted space kb percent fragmented
--------------- ------------------
ITEM_LIST 5163360 4318302.27
845057.73 16.3664306

We have a front end that is polling the database for some set of data.That set of data is returned by opening a ref cursor and passing it back to the calling environment.Now the problem they also want the count of total number of records that will be fetched by my select statement.One option is execute the select statement once ,get the count and pass it.But in that case i will be executuing the query twice once for count other time while openimng for the ref cursor .

I am having a table with contents like

100,p_enter
200,s_enter
i would like the output to be
Variable name cnt_s_enter=1 (this is for 200)
cnt_s_p_enter =1 (this is becoz 100 is both in s_enter and p_enter)
I am working with basic case but thats not working.
select
sum(case when name='s_enter' then 1 else 0 end),
sum(case when name in (s_enter,p_enter) then 1 else 0 end)

I'm needing to return results per month counting records that meet a certain criteria. Some months there will be no results but I need to return a zero rather than having that month omitted from the result set.
This is the pre-existing query:
SELECT TO_CHAR(CRSCHED_DATE,'YYYY/MM'), Count(CPMA.RECORDNUMBER)
FROM CPMA.CPMA CPMA
WHERE (CPMA.CRSCHED_DATE Between TRUNC(ADD_MONTHS(SYSDATE,-12),'MM') And LAST_DAY(ADD_MONTHS(SYSDATE,-1))) AND (CPMA.CHGSTATUS='Duplicate')
GROUP BY TO_CHAR(CRSCHED_DATE,'YYYY/MM')
ORDER BY TO_CHAR(CRSCHED_DATE,'YYYY/MM')
The results returned are accurate, but any month(s) with no records meeting the specified criteria are skipped in the result set.

/* Formatted on 22/01/2013 19:32:50 */
CREATE OR REPLACE PROCEDURE test_rdm_miles (
p_ref_cursor OUT SYS_REFCURSOR
p_success NUMBER)
IS
BEGIN
OPEN p_ref_cursor FOR
SELECT 5168 mem_uid,
[code]....
I have a Procedure with out parameters as a REF CURSOR and response message as p_success.This ref cursor will be returned to the calling service. Is there a way in oracle by which we can identify whether the Ref cursor holds data without actually fetching it. Since if i choose to fetch the data, i will lose one row when i return the ref cursor back to the calling service Or else is there way i can retrieve the row i lose during fetch.
Other alternative what have been suggested is create an object type ,fetch the ref cursor values in object type. Then i can use the ref cursor to return the data by table casting.
one more solution is
OPEN
FETCH
CLOSE
OPEN (AGAIN) { this will lead to redundancy)

i have two tables one as test_master and other one limit master.
test master table structure
ct_id ct_a ct_b ct_C ct_d ct_e...... etc
1 -- -- -- -- --
1 -- -- -- -- --
2 -- -- -- -- --
limit master structure
limit_id ct_a_limit ct_b_limit ct_c_limit ct_d_limit ct_e_limt ..... etc
1 -- -- -- -- -- -- -- --
2 -- -- -- -- -- -- -- --
ct_id and limit_id is match column used for mapping.
now i want the total count of no of records in test_master in which test_master column value not exceed limit master column limit value if any one column exceeds its limit then the same row will be in my count criteria.
how to achieve the same using sql/oracle query.

I want to know that whether we can write a query to add total number of count of each table.
for example:
select count(*) from emp;
count(*)
14
select count(*) from emp_1;
count(*)
15
select count(*) from emp_2;
count(*)
16
My question is that is it possible to add this all the three results and get the value as 45.

I have a table that cannot be changed with a field called transaction_reference in the transactions table. This field contains any number of some values in a look-up table called codes.
The table codes contains 'AA', 'BB', 'CC'.
A typical transaction_reference field may look like 'CC BB' or 'AA' or 'AA CC' or 'AA CC BB' - any number, any order.My goal is to get a count of records grouped by another field from the transactions table.
Transactions table example:
transaction_id | transaction_reference | family
---------------------------------------------
1 | AA BB | foo
2 | BB CC | bar
3 | BB | hello
4 | AA CC BB | foo
5 | BB AA | bar
So the results should look like:
family | code | count
foo | AA | 2
foo | BB | 2
foo | CC | 1
bar | AA | 1
bar | BB | 2
bar | CC | 1
hello | AA | 0
hello | BB | 1
hello | CC | 0
If the counts of 0 (like the third to last and last line above) don't show up I'm ok with that.I put together an explode function like this one here but I'm really not sure where to go from here. I can split the transaction_reference, but I'm not sure what to compare it to or how.
I realize that a field in the transactions table for AA, BB, and CC would be ideal, but I can't do that... the powers that be won't let me change the table.
for each exploded segment from transaction_reference
look for it in the codes table
if it exists, add 1 to the count

I have a string like this:

How can I find the number of lines in this string? I tried using
INSTR('s_list', '

but it gives 0.
Is there any inbuilt function/proc SQL or PL/SQL which can do this?
