Employee Whole Attendance Query - mysql

Question

I am stucked with this problem from long time. Though you will find this is big question, but it's not............
I have following tables, with dummy data, so you can also try it.
users Table with Columns
emp_id emp_Name Joining_Date state_id
1 Lauren 11-07-2011 123
2 John 01-08-2012 234
3 Smith 02-09-2011 234
____________________________________________________
CREATE TABLE users
( emp_id int
, emp_Name varchar(20)
, Joining_Date DATE
, state_id int
);
INSERT INTO users (emp_id, emp_Name, Joining_Date, state_id)
VALUES
(1, 'John', '2011-08-10', 123) ,
(2, 'Smith', '2011-09-11', 234) ;
__________________________________________________________________
cl_doctor_call Table
Subject Call_Date call_Done_By(emp_id)
Call 15-01-2012 1
CA 21-02-2012 2
___________________________________________________________________
CREATE TABLE cl_doctor_call
( Subject VARCHAR(10)
, Call_Date DATE
, call_Done_By INT
) ;
INSERT INTO cl_doctor_call (Subject, Call_Date,call_Done_By)

Chemist 1-02-2012 2
Texo 21-03-2012 1
____________________________________________________________________________________
CREATE TABLE cl_chemist ( Subject VARCHAR(10), Call_Date DATE, call_Done_By INT );
INSERT INTO cl_chemist (Subject, Call_Date,call_Done_By) VALUES ('sub3','2011-08-19',2),('sub5','2011-09-25',1);
___________________________________________________________

);
INSERT INTO cl_Stock (Subject, Call_Date,call_Done_By)
VALUES
('ABC', '2011-10-13', 1) ,
('sub5', '2011-11-17', 2) ;
______________________________________________________
Meetings Table
Subject Meeting_Date call_Done_By(emp_id)
Sub1 11-02-2012 1
Sub2 23-03-2012 2 _____________________________________________________________________________________
CREATE TABLE Meetings ( Subject VARCHAR(10), meet_Date DATE, meet_Done_By INT );
INSERT INTO Meetings (Subject, meet_Date,meet_Done_By)
VALUES
('Planning','2011-11-01',2),
('Deploy','2011-12-15',1);
______________________________________________________________________________________
Leave Table
Subject from_Date to_date Requested_By(emp_id) status
Sub1 01-02-2012 03-02-2012 2 Declined
Sub2 21-03-2012 22-03-2012 1 Approved
Holiday Table
Holiday_Name Holiday_Date States_Id
New Year 01-01-2012 123
Independence Day 15-08-2012 234
______________________________________________________________________________________
CREATE TABLE Holiday ( Holiday_Name VARCHAR(10),Holiday_Date DATE, State_Id_c INT );
INSERT INTO Holiday (Holiday_Name,Holiday_Date,State_Id_c) VALUES ('NEW_YEAR','2012-01-01',123), ('CHRISHMAS','2011-12-25',234);
______________________________________________________________________________________
Replace with date
for stock='Y'
for chemist='Y'
for doctor='Y'
for leave='L'
for Sunday='S'
for meeting ='M'
for Holiday='H'
Hope so still you are with me.
Now Admin will select 'month' and 'year' and according to that attendance report for
employee will displayed.
Output :
Employee Year Month 1 2 3 4 5 6 7.... for all 31 days
John 2011 Nov Y Y Y H Y L S....
Smith 2011 Nov Y Y Y H Y M S.....
. . . ................
. . . ................
&so on &so on &so on & so on
here in output 1,2,3.... are days from 0-31 for a month which we can write using 'case'
Consider if employee is present on day show its status as 'Y' ,if he is on leave show it's status as 'L; if there is Sunday show status 'S' for holiday show 'H' and so on.
So basically I want a write a query to retrieve all these details.
So pl z suggest me ways here, that How can I display this attendance Report by a query or procedure.
I have tried so far this .....

Here I am getting all Sunday's of that month AND All customer calls like Doctor_call,
chemist call, stockist call and meetings entries correctly.
Now I just need to add 'Leave' and Holiday Entries. So anybody can assist me to achieve holidays and leave in my existing procedure?
any suggestions will be helpful for me....

Answer 1

Finally I achieved answer for Attendance Report.
We need to execute this lengthy stored procedure to get monthly attendance of all Employees.
To execute this procedure we need to pass IN parameter as last date of previous month like if we need to see December 2011 attendance Report pass '2011-11-30' AS IN parameter.
