计算特定值 IReport 的行数

Question

我有一列 Status，我想计算有多少行是“Pendings”，有多少行是“Finalized”

我试过这个：

Variable class = java.lang.Integer
Calculation = Sum
ResetType = Report
Increment type = None
Variable expression = $F{tbl_suspensao_status}.equals("Finalized")  ? 0 : 1

但是没有用。

查询：

SELECT
     tbl_suspensao.`codigoBeneficiario` AS tbl_suspensao_codigoBeneficiario,
     tbl_suspensao.`contrato` AS tbl_suspensao_contrato,
     tbl_suspensao.`data_fim` AS tbl_suspensao_data_fim,
     tbl_suspensao.`data_inicio` AS tbl_suspensao_data_inicio,
     tbl_suspensao.`status` AS tbl_suspensao_status,
     tbl_usuario.`nome` AS tbl_usuario_nome,
     tbl_suspensao.`nomeBeneficiario` AS tbl_suspensao_nomeBeneficiario
FROM
     `tbl_usuario` tbl_usuario INNER JOIN `tbl_suspensao` tbl_suspensao ON tbl_usuario.`codigo` = tbl_suspensao.`usuario_id`
WHERE
 AND tbl_suspensao.`data_inicio` BETWEEN  $P{Data_Inicio} AND $P{Data_Fim}

Answer 1

select 
   sum(if(Status = "Pendings", 1, 0)) Pendings, 
   sum(if(Status = "Finalized", 1, 0)) Finalized
 from table

左右

select 
    sum(Status = "Pendings") Pendings, 
    sum(Status = "Finalized") Finalized 
  from t1

Answer 2

SELECT status, count(*) from table where status='pending' or status='finalized' 
group by status

Answer 3

顺序 1 和 0 错误。将表达式更改为

Variable expression = $F{tbl_suspensao_status}.equals("Finalized")  ? 1 : 0

P.S。 SQL 中的计算和是 SQL-solution 而不是 iReport-solution
