Sql Transposing Column Name in Row

Question

i am using Sql Server 2008
tbl_EmployeeProfile
EmployeeId EmployeeName LeaveApplicable Active
1 Sam true true
2 Rahul false false
3 Sameer true true
tbl_MasterLeave
id LeaveCode Description active
1 PL Paid Leave true
2 CL Casual Leave true
3 SL Sick Leave false
tble_LeaveAllocation
EmployeeId Period 1 2 3 .........31
1 2014 18 4
3 2014 20 4
note: tble_Masterleave.id = tble_LeaveAllocation.1( column Name)
i.e  value of tbl_masterleave id is mape with column name of tble_LeaveAllocation 1,2,.....31
Expected out put
EmployeeId EmployeeeName Period PL CL
1 Sam 2014 18 4
3 Sameer 2014 20 4
Note: show only record who is active = true & leaveApplicable = true  .
why i made this table structure  because non of organization leave type are not fixed, so user can customize leave according their requirment , so i made tbl_ allocation table with 1 to 31 column , so user can allocate leave type max 31.
please advice me is it right method or any other good alternative solution 
Thanks Best Regard Naweez

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:

Why are you so special that you do not have to post DDL? I Googled you and got nothing that would grant you privilege. 
You have the manners of a pig and your code is garbage. Look up tibbling in the “code smells” paper. That is what we call your “tbl-”
 prefix when we laugh at you. 
Why do you write SQL with assembly language flags? SQL programmers do not! Why did you use the term “master_” on a table name? This term is from tape files and network DB; it has nothing to do with RDBMS!! 
Why do you think that “active” is an attribute? NO! It is a value of some particular attribute and needs a temporal range. 
There is no generic “id” in RDBMS! Remember the Law of Identity from your first freshman logic class? Rows are not records, so you got that term wrong. We do not use mappings in RDBMS; we have REFERENCES. 
CREATE TABLE Personnel
(emp_id CHAR(10) NOT NULL PRIMARY KEY,
 emp_name VARCHAR(35) NOT NULL);
CREATE TABLE Leave_Codes
(leave_code CHAR(2) NOT NULL PRIMARY KEY,
 leave_code_description VARCHAR (20) NOT NULL);
INSERT INTO Leave_Codes
VALUES 
('PL', 'Paid Leave'),
('CL', 'Casual Leave'),
('SL', 'Sick Leave);
I might have done this: 
CREATE TABLE Employee_Leaves
(emp_id CHAR(10) NOT NULL
 REFERENCES Personnel(emp_id)
 leave_start_date DATE NOT NULL,
 leave_end_date DATE NOT NULL,
CHECK(leave_start_date < leave_end_date),
 leave_code CHAR(2) NOT NULL
  REFERENCES Leave_Codes (leave_code),
 PRIMARY KEY (??),

No, you did this out of ignorance. You do not understand RDBMS or SQL.  YHou do not know any of the basics.
