This is a case for Case. See Microsoft documentation for Case (Transact SQL)[^]

If Gender is a numeric data type:

SQL

Select TOP 1000 ID,Num,FirstName,Nickname,LastName, Case Gender When 0 Then 'Male' When 1 Then 'Female' Else 'N/A' End As Gender FROM TravelAgency.dbo.CustomersViews

If Gender is a character data type:

SQL

Select TOP 1000 ID,Num,FirstName,Nickname,LastName, Case Gender When '0' Then 'Male' When '1' Then 'Female' Else 'N/A' End As Gender FROM TravelAgency.dbo.CustomersViews
