查詢兩個差不多相同的表，乙個是入庫表，乙個是退貨表，字段大致相同，但是有所差異，入庫表的數量和所有金額都是正數，退貨表的數量和金額都是負數，所以不能join鍊錶查詢，需要分開查詢出兩個tolist；但是return只能有乙個，不能return兩次，並且查詢出來的資料是放到乙個結算表，也不能有兩個action。所以我查詢兩次，一次join入庫表，一次join退貨表，查詢出來的資料到兩個list裡

tbinvoicestype.invoicestypeid

tbpurchasestorage.settlestateid!=2&&tbpurchasestorage.settlestateid!=4
select new suppliervo
).tolist();
