When i select ok button inside JDBC Data Source form coming only columns empoyeeid and name. it's eliminated two columns name.Please tell me,how i will take all columns inside Data Sets(Query name, inside all columns) then i can create reports throuhg drag and drop.please give me ideas.
Query is:-

select employees.employeeid, employees.name,designations.name,d.name from employees INNER JOIN designations ON employees.designation_id=designations.id INNER JOIN departments as d ON employees.department_id=d.id
