git push remote permission to git denied to user with 403 error

When am trying to push files to git am getting an error ” git push remote permission to git denied to user with 403 error “.It is actually showing the wrong user name ,so first we need to change the git stored Credential user

Mysql query to fetch current month data

Sometimes we need to show only current month data in the application ,so for easy handling the data we should use a Mysql query to fetch current month data.Let we check out how to do that using one MySQL query

See below the Mysql query to fetch current month data


SELECT *
FROM leads
WHERE MONTH(date) = MONTH(CURRENT_DATE())
AND YEAR(date) = YEAR(CURRENT_DATE())
// leads= Table Name
// date = date field name

Here we are fetching current month data using the feature MONTH(CURRENT_DATE()) and MONTH(date)

MONTH(CURRENT_DATE()) will result 8 (since current month is Aug)

Next feature we are using in Mysql query to fetch current month data is YEAR(date) and YEAR(CURRENT_DATE())

YEAR(CURRENT_DATE()) will result 2019 (since today is Aug 24 2019)

so actual Mysql query to fetch current month data will work like this

SELECT *
FROM leads
WHERE MONTH(date) = 9
AND YEAR(date) = 2019

so it will fetch all result form database table leads that having date field value is in august month
