No error but if does not exists, data does not insert.
Thanks in advance.

Probably, the problem is your datatypes and conversions:

SQL

@date AS DATETIME
...
CONVERT(VARCHAR(24),employee_timeIn,107) = @date

I'm not sure why you are converting what appears to be a Date or DateTime column to a Varchar before you comparte it to a DateTime value, but I know I wouldn't - I would compare the DataTime cvlaues directly.

What is the column format? And why do you think it is a good idea to convert it to a Varchar before the comparison - because there are so many ways that that could go wrong.

Someone before me used it. I copied the first part. Just inserting the last one.
I'm not supposed to "alter" anything from the original. Thanks anyway.

Try this

SQL

DECLARE @empID UNIQUEIDENTIFIER
DECLARE @day DATETIME
	
SET @empID = @employee_id
SET @day = @date

SELECT
	el.employee_id
	, e.history_id
	, CONVERT(VARCHAR(24),e.employee_timeIn,107) AS rawDate
	, e.employee_workHours
	, e.dayType
INTO #temp
FROM employee_list el
INNER JOIN employee_history e ON e.employee_id = el.employee_id
WHERE e.employee_id = @employee_id
	AND CONVERT(VARCHAR(24),e.employee_timeIn,107) = @date
	AND el.delete_status = 0 
	AND isActive = '1'   
	AND e.delete_status = 0           
ORDER BY e.employee_timeIn ASC

IF @@ROWCOUNT = 0
	BEGIN
	INSERT INTO #temp
	(
	employee_id
	, history_id
	, rawDate
	, employee_workHours
	, dayType
	)
	VALUES
	(
	@empID
	, '00000000-0000-0000-0000-000000000000'
	, @day
	, ''
	, ''
	)
	END

SELECT * FROM #temp
