Error in writing condition in a query

Question

Hi following is a working code
declare @dte as datetime='2015-04-01'
declare @StDt as Datetime = DATEADD(mm,DATEDIFF(mm,0,@dte), 0)
declare @EnDt as datetime = DATEADD( DD, -1, DATEADD(mm,DATEDIFF(mm,0,@dte) + 1, 0));
DECLARE @query AS NVARCHAR(MAX);
create table #bus_master(bus_id int,bus_name varchar(50),uname varchar(50))
insert into #bus_master values(100,'A','lekshmi')
insert into #bus_master values(101,'B','lekshmi')
insert into #bus_master values(102,'C','lekshmi')
insert into #bus_master values(103,'D','krishna')
insert into #bus_master values(104,'E','krishna')
insert into #bus_master values(105,'F','krishna')
create table #busdetails( bus_id int,tour_date datetime,status varchar(10))
insert into #busdetails values(103,'2013-10-01','booked')
insert into #busdetails values(102,'2013-10-01','booked')
insert into #busdetails values(100,'2013-10-02','booked')
;WITH Dates AS(
SELECT DATEADD( DD, ROW_NUMBER() OVER( ORDER BY (SELECT NULL)) - 1, @StDt) Month_date
FROM (VALUES(0),(0),(0),(0),(0),(0))E(N),
(VALUES(0),(0),(0),(0),(0),(0))E2(N)
SELECT @Query = 'SELECT m.bus_id as ID ' + CHAR(13)
+ (SELECT CHAR(9) + ',MAX( CASE WHEN tour_date = ''' + CONVERT( CHAR(8), Month_date, 112) + ''' THEN status END) AS ' + QUOTENAME( CONVERT( char(2), Month_date, 103)) + CHAR(13)
FROM Dates
WHERE Month_date BETWEEN @StDt AND @EnDt
ORDER BY Month_date
FOR XML PATH(''),TYPE).value('.','varchar(max)')
+ '
FROM #bus_master m
LEFT
JOIN busdetails b ON m.bus_id = b.bus_id
GROUP BY m.bus_id '
execute(@Query)
drop table #bus_master
drop table #busdetails
iam getting the ouput correctly
my requirement is i want to write a condition
here
JOIN busdetails b ON m.bus_id = b.bus_id
i want to write this statement as
JOIN busdetails b ON m.bus_id = b.bus_id and m.uname='lekshmi'
when i tried this code iam getting error
how to solve this

Could you try below code?
If it doesn't work, please post the error messages that you get.
declare @dte as datetime='2015-04-01'

declare @EnDt as datetime = DATEADD( DD, -1, DATEADD(mm,DATEDIFF(mm,0,@dte) + 1, 0));
DECLARE @query AS NVARCHAR(MAX);
create table #bus_master(bus_id int,bus_name varchar(50),uname varchar(50))
insert into #bus_master values(100,'A','lekshmi')
insert into #bus_master values(101,'B','lekshmi')
