How to intersect between a view and a table in mysql? - mysql

Question

I've a view and a table. I'm inserting data into table on the basis of that view. I want that view to eliminate same data that is already inserted into table.
This is the view which is named view_1.
CREATE VIEW view_1 AS
SELECT
y.employee_registration_id,
x.employee_first_name,
x.employee_last_name,
x.employee_email,
y.employee_current_salary_amount,
(SELECT
x.salary_of_year_month_YearMonth
FROM
salary_of_years_months x
LEFT JOIN
status_salary_of_years_months y ON x.salary_of_year_month_id = y.salary_of_year_month_id
WHERE
y.year_month_status = 'Ongoing') AS salary_of_year_month_YearMonth,
(SELECT
CONCAT(MONTHNAME(x.salary_of_year_month_YearMonth),
'-',
YEAR(x.salary_of_year_month_YearMonth))
FROM
salary_of_years_months x
LEFT JOIN
status_salary_of_years_months y ON x.salary_of_year_month_id = y.salary_of_year_month_id
WHERE
y.year_month_status = 'Ongoing') AS salary_of_year_month_YearMonth_MonthYear
FROM
basic_info_employees x
LEFT JOIN
current_salary_employees y ON x.employee_registration_id = y.employee_registration_id
WHERE
y.employee_current_salary_amount > 0;
This is the table.
CREATE TABLE `salary_tracker_employees` (
serial_no INT(4) NOT NULL AUTO_INCREMENT,
employee_registration_id INT(4),
employee_first_name VARCHAR(30),
employee_last_name VARCHAR(30),
employee_email VARCHAR(30),
salary_of_year_month_YearMonth VARCHAR(50),
employee_current_salary_amount DOUBLE(8 , 2 ),
PRIMARY KEY (serial_no),
UNIQUE (employee_registration_id , salary_of_year_month_YearMonth)
);
I want to get a view that will intersect the between view_1 and salary_tracker_employees.
