怎么把这些语句拼起来啊

select '缩合' , '78#' , fdecimal as 一月 from t_BOS200002318,t_BOS200002318entry
where t_BOS200002318.fid=t_BOS200002318entry.fid and t_BOS200002318.fcombobox4='1月'

select fdecimal4 as 二月 from t_BOS200002318,t_BOS200002318entry
where t_BOS200002318.fid=t_BOS200002318entry.fid and t_BOS200002318.fcombobox4='2月' 

select fdecimal4 as 三月 from t_BOS200002318,t_BOS200002318entry
where t_BOS200002318.fid=t_BOS200002318entry.fid and t_BOS200002318.fcombobox4='3月'
