SQL query must count number of engaged, end, MEP per month
Hi all
Need Sql query with group by category and count of the PEM attached, terminated, current for every month for the year.
Create table per_all_people_f
(person_id varchar2(30),
original_date_of_hire date)
Create table per_all_assignments_f
(person_id varchar2(30),
employee_category varchar2(30))
create table per_periods_of_service
(person_id varchar2(30),
actual_termination_date date)
insert into per_all_people_f
values(1,to_date('01-FEB-2014','DD-MON-YYYY'));
/
insert into per_all_people_f
values(2,to_date('10-FEB-2014','DD-MON-YYYY'));
/
insert into per_all_people_f
values(3,to_date('10-dec-2013','DD-MON-YYYY'));
/
insert into per_all_people_f
values(4,to_date('10-MAR-2014','DD-MON-YYYY'));
/
insert into per_all_people_f
values(5,to_date('10-dec-2013','DD-MON-YYYY'));
/
insert into per_all_assignments_f
values(1,'ADMIN');
/
insert into per_all_assignments_f
values(2,'TECH');
/
insert into per_all_assignments_f
values(3,'TECH');
/
insert into per_all_assignments_f
values(4,'ADMIN');
/
insert into per_all_assignments_f
values(5,'ADMIN');
/
insert into per_periods_of_service
values(3,to_date('05-feb-2014','DD-MON-YYYY'));
/
Desired output. "()" are to explain only.
Explanation of columns:
Hired_ADMIN = used category ADMIN
Term _Admin = employee fired from category ADMIN
Current_ADMIN = Total current employees in category ADMIN
Hired_TECH = used in category TECH
Term_TECH = employee fired in category TECH
Current_TECH = Total current employees in category TECH
Month Hired_ADMIN Term_ADMIN Current_ADMIN Hired_TECH Term_TECH Current_TECH Jan-14 0 0 1 0 0 10 (example) Feb-14 2 1 2 0 1 9
Tried the queries below: but not able to get the desired output grouping...
I made different requests for In (Hired), Out (Terminated), need help for current employees by month and grouping as stated above the desired output.
1 request for employees
select in_month,in_month_name
, count(decode(employee_category,'ADMIN', person_id)) ADMIN_IN
--, count(decode(employee_category,'DOCT', person_id)) DOCT_IN
--, count(decode(employee_category,'NURS', person_id)) NURS_IN
, count(decode(employee_category, 'TECH', person_id)) TECH_IN
from
(
select distinct
papf.person_id,
paaf.employee_category,
trunc(papf.original_date_of_hire, 'mm') in_month,
decode(userenv('LANG'),'US',to_char(papf.original_date_of_hire, 'Month'),'AR',to_char(papf.original_date_of_hire, 'Month','nls_date_language=Egyptian'),'') in_month_name
from per_all_people_f papf
,per_all_assignments_f paaf
where papf.person_id = paaf.person_id
and Papf.ORIGINAL_DATE_OF_HIRE between to_date('01-JAN-'||:P_YEAR) and to_date('31-dec-'||:P_YEAR)
and paaf.employee_category is not null
)
group
by in_month,in_month_name
ORDER BY in_month
2. request for completed employees:
select out_month,out_month_name
, count(decode(employee_category,'ADMIN', person_id)) ADMIN_OU
--, count(decode(employee_category,'DOCT', person_id)) DOCT_OUT
--, count(decode(employee_category,'NURS', person_id)) NURS_OUT
, count(decode(employee_category, 'TECH', person_id)) TECH_OUT
from
(
select distinct
papf.person_id,
paaf.employee_category,
trunc(actual_termination_date,'mm') out_month,
decode(userenv('LANG'),'US',to_char(actual_termination_date, 'Month'),'AR',to_char(actual_termination_date, 'Month','nls_date_language=Egyptian'),'') out_month_name
from per_all_people_f papf
,per_all_assignments_f paaf
,per_periods_of_service ppos
where papf.person_id = paaf.person_id
and ppos.person_id = papf.person_id
and ppos.actual_termination_date between to_date('01-JAN-'||:P_YEAR) and to_date('31-dec-'||:P_YEAR)
and paaf.employee_category is not null
)
group
by out_month,out_month_name
ORDER BY out_month
Pls suggest the sql query for current employees monthly and Hired of the EMP, Terminated the PEM group, according to the current EME Emp_Category.
Please suggest...
Thanks and greetings
Afzal.

SDO_RELATE within PL/SQL query with rownum clause runs slowly on 12 c - works great on 10 g
Hello
I use the database 12.1.0.2 with a node 2 RAC on Windows.
I am struck by a really weird performance problem with a particular query. Bear with me while I try to explain...
I have a chart with lines 30 sdo_geometry million, in 7 partitions with a local partitioned spatial index divided. Called BIG_PARTITIONED_TABLE for this example.
I query the table to search for one line with a geometry that is equal to the geometry of my request. In this case I use sdo_relate with "mask = equal". Instantly returns:
SQL> select id, geometry 2 from BIG_PARTITIONED_TABLE o 3 where sdo_relate(o.geometry, sdo_geometry(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1), 4 SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272)), 'mask=equal') = 'TRUE' 5 and rownum = 1; ID ---------- GEOMETRY(SDO_GTYPE, SDO_SRID, SDO_POINT(X, Y, Z), SDO_ELEM_INFO, SDO_ORDINATES) ------------------------------------------------------------------------------- 2.5405E+12 SDO_GEOMETRY(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1), SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272)) Elapsed: 00:00:00.10
But if I put the same query in PL/SQL, so it takes 21 seconds:
SQL> declare 2 l_id number; 3 l_geom sdo_geometry; 4 l_window_geom sdo_geometry; 5 begin 6 l_window_geom := sdo_geometry(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1), 7 SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272)); 8 9 select id, geometry 10 into l_id, l_geom 11 from BIG_PARTITIONED_TABLE o 12 where sdo_relate(o.geometry, l_window_geom, 'mask=equal') = 'TRUE' 13 and rownum = 1; 14 15 end; 16 / PL/SQL procedure successfully completed. Elapsed: 00:00:21.13
If I remove the "rownum = 1", then it returns instantly:
SQL> declare 2 l_id number; 3 l_geom sdo_geometry; 4 l_window_geom sdo_geometry; 5 begin 6 l_window_geom := sdo_geometry(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1), 7 SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272)); 8 9 select id, geometry 10 into l_id, l_geom 11 from BIG_PARTITIONED_TABLE o 12 where sdo_relate(o.geometry, l_window_geom, 'mask=equal') = 'TRUE'; 13 14 end; 15 / PL/SQL procedure successfully completed. Elapsed: 00:00:00.03
If using sdo_equal instead of sdo_relate and keep the "rownum = 1", then it returns instantly.
SQL> declare 2 l_id number; 3 l_geom sdo_geometry; 4 l_window_geom sdo_geometry; 5 begin 6 l_window_geom := sdo_geometry(2002, 2157, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1), 7 SDO_ORDINATE_ARRAY(604853.595, 692379.864, 604879.046, 692350.272)); 8 9 select id, geometry 10 into l_id, l_geom 11 from BIG_PARTITIONED_TABLE o 12 where sdo_equal(o.geometry, l_window_geom) = 'TRUE' 13 and rownum = 1; 14 15 end; 16 / PL/SQL procedure successfully completed. Elapsed: 00:00:00.13
Here is a comparison of the plans to explain. First, here's the good thing, that is using the spatial index (BIG_PARTITIONED_TABLE_SPIND):
select id, GEOMETRY FROM BIG_PARTITIONED_TABLE O WHERE SDO_EQUAL(O.GEOMETRY, :B1 ) = 'TRUE' AND ROWNUM = 1 call count cpu elapsed disk query current rows ------- ------ -------- ---------- ---------- ---------- ---------- ---------- Parse 1 0.00 0.00 0 0 0 0 Execute 1 0.01 0.02 0 39 0 0 Fetch 1 0.00 0.01 0 31 0 1 ------- ------ -------- ---------- ---------- ---------- ---------- ---------- total 3 0.01 0.04 0 70 0 1 Misses in library cache during parse: 0 Optimizer mode: ALL_ROWS Parsing user id: 263 (recursive depth: 1) Number of plan statistics captured: 1 Rows (1st) Rows (avg) Rows (max) Row Source Operation ---------- ---------- ---------- --------------------------------------------------- 1 1 1 COUNT STOPKEY (cr=99 pr=0 pw=0 time=43307 us) 1 1 1 PARTITION RANGE ALL PARTITION: 1 7 (cr=99 pr=0 pw=0 time=43297 us cost=0 size=66 card=1) 1 1 1 TABLE ACCESS BY LOCAL INDEX ROWID BIG_PARTITIONED_TABLE PARTITION: 1 7 (cr=99 pr=0 pw=0 time=43280 us cost=0 size=66 card=1) 1 1 1 DOMAIN INDEX BIG_PARTITIONED_TABLE_SPIND (cr=98 pr=0 pw=0 time=43250 us)
Then the slow that does not use the spatial index.
select id, GEOMETRY FROM BIG_PARTITIONED_TABLE O WHERE SDO_RELATE(O.GEOMETRY, :B1 , 'mask=equal') = 'TRUE' AND ROWNUM = 1 call count cpu elapsed disk query current rows ------- ------ -------- ---------- ---------- ---------- ---------- ---------- Parse 1 0.01 0.00 0 0 0 0 Execute 1 0.03 0.03 0 1123 0 0 Fetch 1 24.25 24.25 0 499429 0 1 ------- ------ -------- ---------- ---------- ---------- ---------- ---------- total 3 24.30 24.29 0 500552 0 1 Misses in library cache during parse: 1 Misses in library cache during execute: 1 Optimizer mode: ALL_ROWS Parsing user id: 263 (recursive depth: 1) Number of plan statistics captured: 1 Rows (1st) Rows (avg) Rows (max) Row Source Operation ---------- ---------- ---------- --------------------------------------------------- 1 1 1 COUNT STOPKEY (cr=499532 pr=0 pw=0 time=24289612 us) 1 1 1 HASH JOIN RIGHT SEMI (cr=499532 pr=0 pw=0 time=24289586 us cost=32 size=144 card=1) 1 1 1 VIEW VW_NSO_1 (cr=103 pr=0 pw=0 time=31110 us cost=29 size=98016 card=8168) 1 1 1 COLLECTION ITERATOR PICKLER FETCH SDO_PQRY (cr=103 pr=0 pw=0 time=31104 us cost=29 size=16336 card=8168) 16914892 16914892 16914892 PARTITION RANGE ALL PARTITION: 1 7 (cr=499429 pr=0 pw=0 time=28678375 us cost=3 size=6600 card=100) 16914892 16914892 16914892 TABLE ACCESS FULL BIG_PARTITIONED_TABLE PARTITION: 1 7 (cr=499429 pr=0 pw=0 time=23406547 us cost=3 size=6600 card=100)
I tried adding an indication / * + index (o BIG_PARTITIONED_TABLE_SPIND) * / but that did not help.
I am struck this issue during testing of upgrade 10.2.0.5 to 12.1.0.2. The query works perfectly on 10g - we note only that this question on 12 c.
I can't use sdo_equal as the real mask that we want is equal + dommagescausdspar + covers. I'm just using equal here to simplify the test.
I use "rownum = 1" because I want to just the first result. In practice I can rewrite probably is a FOR LOOP, I get out after the first result, but that seems all just awful.
Any ideas? If anyone has seen anything like this before? Its an optimizer delivers really so I'm going to cross post the SQL Forum after a certain time, but thought I would post it here first.
Thank you
John

Clarification of the SQL query in 2 day + Guide APEX
I worked through the Oracle Database Express Edition 2 day + Application Express Developer's Guide, and try to decipher the SQL query in Chapter 4 (building your app).
The code is:
SELECT d.DEPARTMENT_ID,
d.DEPARTMENT_NAME,
(select count (*) from oehr_employees where department_id = d.department_id)
"Number of employees", he said.
substr (e.first_name, 1, 1) |'. ' || Select 'Name Manager',
c.COUNTRY_NAME 'place '.
OEHR_DEPARTMENTS d,
E OEHR_EMPLOYEES
OEHR_LOCATIONS l,
C OEHR_COUNTRIES
WHERE d.LOCATION_ID = l.LOCATION_ID
AND l.COUNTRY_ID = c.COUNTRY_ID
AND e.department_id = d.DEPARTMENT_ID
AND d.manager_id = e.employee_id
AND instr (superior (d.department_name), superior (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0)
I don't know exactly what is happening in the last line. I think I understand what the different functions but I'm not clear on the use of the: P2_REPORT_SEARCH string.
What does this string? This code simply checking that d.department_name isn't NA?
I have SQL experience but am not very familiar with the Oracle PL/SQL implementation. Can someone please give me a brief breakdown that check is doing in the context of the overall query? The application seems to work even if the conditional statement is not included.
Thank you.

Thanks for the reply. I apologize if the information I added was incomplete. The code came from the day 2 + Application Express (version 4.2) Developer Guide.
In the section 'your own Application of 4 Buuilding' https://docs.oracle.com/cd/E37097_01/doc.42/e35122/build_app.htm#TDPAX04000 , they describe the creation of a report
page that includes the "manager_id" and 'location_id '. The SQL query, I pasted above extracted from the data in other tables to substitute the real 'name of the Manager' and 'rent '.
for the corresponding ID values. It makes sense, and the part of the SQL query that explicitly doing this makes sense.
However, given that the document is a guide for the development of the APEX, I guess the command:
AND instr (upper (d.department_name), upper (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0
done something valuable, and I do not recognize what is exactly the value.
From a practical point of view why would I need to include this conditional statement? Which only added to the application?
Looking at the guide in question, it is clear that the
AND instr(upper(d.department_name),upper(nvl(:P2_REPORT_SEARCH,d.department_name)))>0
the line is completely unnecessary in the context of this tutorial, and it can be removed. The search in the tutorial app page is implemented by using a report filter interactive rather than a P2_REPORT_SEARCH element, which does not seem to exist at all. (It's a quirk of the APEX that bind variable references to non-existent items are replaced with NULL silently rather than exceptions). I thought that perhaps it would be legacy code a version of the tutorial prior to the introduction of interactive reports at the APEX 3.1, but I can't find explicit instructions to create such an element of filter in the 3.0 tutorial. I guess it must have been automatically generated by the application wizard when you create a standard report page.
If you do not want to see the effect he would have (as described in the post above), leave it in the source report, add a text element of P2_REPORT_SEARCH, and a button "submit" on page 2 and experimenting to find different values of the element and clicking on the submit button...

Hello
Suppose I need to check the number of records of 30 tables in the oracle database in a particular schema, it may have hundreds of tables.
How to check with simple sql query.I know that under method,
Select count (*) from
Table1, table2, table3... table30;But I need in format below. If I use Group by we will get but we must specify all 30 tables to groupby, is any alternative group instead of keep all 30 tables
SELECT TABLENAME, COUNT (*)
OF table1, table2, table3... table30Group of table1, table2, table3... table30;
Try the following query if all tables are present in the same pattern in the case otherwise you must use dba_tables:
SELECT table_name, to_number( extractvalue( XMLTYPE( dbms_xmlgen.getxml('select count(*) c from '||table_name)) ,'/ROWSET/ROW/C')) count FROM user_tables WHERE table_name IN ('A','B','C') ORDER BY table_name; -

I created all the elements of the required page
I get the error message like missing expression
to test, I created a function to return the query, it works very well know to return a query that gives me desired report
am I missing something?
Help, please

can take you a look at page901 once again please and a function named months_namex

The immediate cause of this error is simply incorrect report headings function call syntax:
return months_namex(to_date(:p901_fromdate,'dd-mon-yyyy'),to_date(:p901_todate,'dd-mon-yyyy')This should be:

Hello
I want to run and store the results of a dynamic sql query in a strored procedure.
I get the following variables of the user running: v_column_names, v_table_name, v_col, v_value
The query will be like:
v_query: = 'SELECT'. v_column_names | ' A ' | v_table_name | ' WHERE ' | v_col |' = ' | v_value;
for example v_column_names: = 'ACCOUNT_NUM, SYSTEM_ID, ENTITY_ID ';
v_table_name: = 'ACCOUNT '.
v_col: = 'COUNTRY_CODE ';
v_value: = "USA";
Here is what I tried
DECLARE
v_column_names VARCHAR (200): = 'ENTITY_ID, SYSTEM_ID, ACCOUNT_NUM;
v_table_name VARCHAR (200): = 'ACCOUNT '.
v_col VARCHAR (200): = 'COUNTRY_CODE ';
v_value VARCHAR (200): = "'USA"';
TYPE column_record () IS RENDERING
VARCHAR2 (200) C1: = null;
C2 VARCHAR2 (200): = null;
C3 VARCHAR2 (200): = null
);
TYPE st_table IS TABLE OF column_record INDEX DIRECTORY.
pk_table st_table;
NUMBER of v1: = 1;
BEGIN
v_select: = 'SELECT'. v_column_names | ' A ' | v_table_name | ' WHERE ' | v_col |' = ' | v_value;
EXECUTE IMMEDIATE v_select COLLECT LOOSE pk_table.
I'm IN 1.pk_table.count LOOP
DBMS_OUTPUT. Put_line (pk_table (v1). (C1);
DBMS_OUTPUT. Put_line (pk_table (v1). (C2);
DBMS_OUTPUT. Put_line (pk_table (v1). (C3);
v1: = v1 + 1;
END LOOP;
END;
The number of column names in v_column_names is dynamic, so I need a way to store the results and then manipulate them.
I look forward to your reply.
EDIT: The real question:
1. in the settings I have pass the table name and the value of the primary key of the row I want to delete.
2. He then checks if this line is referenced anywhere, removes the reference, and then deletes the current line. This can go, until all the rows that are referenced are removed.
The above code, I have provided a small part of the largest of stored procedure.
Thank you all, I found the tips very helpful. I found a solution to my problem:
It generates all removal requests to remove a specific line. Not what I wanted, but this does not solve my problem.
The reason why is that I discovered that we do not use the ON DELETE CASCADE that we don't remove a record accidentally, I know we have an option to restore, but it is just in case something goes wrong.

I want to map a combination of batch of degree for a class rooms group of such distance that they make full use of the maximum capacity of the class rooms within a group (ideally), or as close to this as possible. Can it be done with a SQL query?
Any response will be appreciated.

Published by: Bilal on December 27, 2012 10:07Bilal, thanks for the nice problem! Another possibility to double check is to write a small PL/SQL function that returns 1 if a duplicate id is found, then equate to 0: "NUMBER of RETURN of Duplicate_Token_Found (p_str_main in VARCHAR2, p_str_trial VARCHAR2). It should analyze the second string and could use p_str_main LIKE '%', | l_id | ', %' for each id. In any case, the query complete (without that) is given below:

I think you want to put this on a report or something. I have what would be easier to do this logic there. But if you want that this is possible.
Like thiswith temp_aaa as (select '111' a_id ,'12345' b_id from dual union all select '222' ,'12345' from dual union all select '333' ,'12000' from dual union all select '444' ,'10000' from dual ) , wanted_rows as ( select '123456' B_ID from dual) select temp_aaa.A_ID || temp_aaa.B_ID IDS from temp_aaa ,wanted_rows where temp_aaa.b_id = wanted_rows.b_id union all select 'NO ROWS' FROM DUAL WHERE (SELECT COUNT(*) FROM TEMP_AAA, wanted_rows WHERE TEMP_AAA.B_ID = wanted_rows.B_ID) = 0In addition, you mix var and number of always use the same type or convert explicitly (to_number or to_char)
WITH MATCH_ROWS AS ( SELECT A_ID||B_ID IDS FROM TEMP_AAA WHERE B_ID =12345 -- varchar2(10) number ), ...And again in the
THEN (SELECT NVL((SELECT IDS FROM TEMP_AAA WHERE B_ID =12345),'NO ROWS') IDS FROM DUAL) -- varchar2(10) numberKind regards
