SQL Server 2014 if exists with multiple begin and end - sql

Question

I have this line of codes:
if exists(select a.id, a.user_id
from AEmployeeLogs a
inner join AUsers b on b.id = a.user_id
where b.username = #username
and b.password = #password
and convert(date, a.date_in) = convert(date, dateadd(HOUR, 15, getdate())))
select 'Exist' as result;
else
begin
select
a.id, username, firstname, lastname, user_image, UserType, title,
'user_type_title', is_cashier,
case
when #num is null then 1
else #num + 1
end 'number'
from
dbo.AUsers a
inner join
ALookUp b on b.id = a.UserType
left join
AEmployeeLogs c on c.user_id = a.id
where
a.username = #username and a.password = #password
end
declare #id int;
select #id = a.id
from dbo.AUsers a
INNER JOIN ALookUp b
on b.id = a.UserType
where username = #username and password = #password
begin
INSERT INTO AEmployeeLogs (date_in,[user_id],note,isactive)
select dateadd(HOUR, 15, getdate()), #id, '',0
where #id is not null
end
The If Exists function works properly, but when I looked at the table AEmployeeLogs, it still inserts even though the is exists what is the proper way of writing my else statement when i have multiple begin and end functions in my query
NOTE: The first begin and end works it didn't select but the 2nd one works need help

Answer 1

Like already stated in the comments, the scope of the else has already ended after the first end.
Like following, it should work as expected:
IF EXISTS (
SELECT a.id,
a.user_id
FROM AEmployeeLogs a
INNER JOIN AUsers b ON b.id = a.user_id
WHERE b.username = #username
AND b.password = #password
AND CONVERT(DATE, a.date_in) = CONVERT(DATE, dateadd(HOUR, 15, getdate()))
)
SELECT 'Exist' AS result;
ELSE
BEGIN
SELECT a.id, username, firstname, lastname, user_image, UserType, title, 'user_type_title', is_cashier,
CASE
WHEN #num IS NULL
THEN 1
ELSE #num + 1
END 'number'
FROM dbo.AUsers a
INNER JOIN ALookUp b ON b.id = a.UserType
LEFT JOIN AEmployeeLogs c ON c.user_id = a.id
WHERE a.username = #username
AND a.password = #password
DECLARE #id INT;
SELECT #id = a.id
FROM dbo.AUsers a
INNER JOIN ALookUp b ON b.id = a.UserType
WHERE username = #username
AND password = #password
INSERT INTO AEmployeeLogs (
date_in,
[user_id],
note,
isactive
)
SELECT dateadd(HOUR, 15, getdate()),
#id,
'',
0
WHERE #id IS NOT NULL
END
