What percentage of male employees hired throughout the years 2009 are married?
male refers to Gender = 'M'; hired throughout the years 2009 refers to Year(HireDate) = 2009; married refers to MaritalStatus = 'M'; percentage = DIVIDE(count(BusinessEntityID(Gender = 'M'& Year(HireDate) = '2009& MaritalStatus = 'M')), count(BusinessEntityID(Gender = 'M'& Year(HireDate) = 2009)))


SELECT CAST(SUM(CASE WHEN MaritalStatus = 'M' THEN 1 ELSE 0 END) AS REAL) * 100 / COUNT(BusinessEntityID) FROM Employee WHERE SUBSTR(HireDate, 1, 4) = '2009' AND Gender = 'M'
