Kann nicht von String werfen

Question

ich habe 2 Parameter, die Parameter-Klasse Boolean ist: java.lang.String für: Abfrage und pSalesType

Standardausdruck der Abfrage wie folgt aussehen wird:

(new String("all").equals($P{pSales_type}) ? "SELECT SALESMAN, SALES_AMOUNT, SALES_TYPE FROM (SELECT T1.SYS_USERNAME AS SALESMAN, SUM(REQ_SALES_AMOUNT) AS SALES_AMOUNT, 'Requisition' AS SALES_TYPE FROM t_requisition LEFT JOIN t_system_user T1 ON T1.SYSUSER_ID = T_REQUISITION.ENTERED_BY WHERE REQ_SALES_AMOUNT IS NOT NULL AND REQ_PROC_STATUS = 'Approved' UNION ALL SELECT T1.SYS_USERNAME AS SALESMAN, SUM(WRO_SALES_AMOUNT) AS SALES_AMOUNT, 'Work Order' AS SALES_TYPE FROM t_work_order LEFT JOIN t_system_user T1 ON T1.SYSUSER_ID = t_work_order.ENTERED_BY WHERE WRO_SALES_AMOUNT IS NOT NULL AND WRO_APPROVAL_STATUS = 'Y') xx GROUP BY SALESMAN, SALES_TYPE " : 
(new String("rq").equals($P{pSales_type}) ? "SELECT T1.SYS_USERNAME AS SALESMAN, SUM(REQ_SALES_AMOUNT) AS SALES_AMOUNT, 'Requisition' AS SALES_TYPE FROM t_requisition LEFT JOIN t_system_user T1 ON T1.SYSUSER_ID = T_REQUISITION.ENTERED_BY WHERE REQ_SALES_AMOUNT IS NOT NULL AND REQ_PROC_STATUS = 'Approved'" : 
(new String("wo").equals($P{pSales_type}) ? "SELECT T1.SYS_USERNAME AS SALESMAN, SUM(WRO_SALES_AMOUNT) AS SALES_AMOUNT, 'Work Order' AS SALES_TYPE FROM t_work_order LEFT JOIN t_system_user T1 ON T1.SYSUSER_ID = t_work_order.ENTERED_BY WHERE WRO_SALES_AMOUNT IS NOT NULL AND WRO_APPROVAL_STATUS = 'Y'" : 
"SELECT T1.SYS_USERNAME AS SALESMAN, SUM(REQ_SALES_AMOUNT) AS SALES_AMOUNT, 'Requisition' AS SALES_TYPE FROM t_requisition LEFT JOIN t_system_user T1 ON T1.SYSUSER_ID = T_REQUISITION.ENTERED_BY WHERE REQ_SALES_AMOUNT IS NOT NULL AND REQ_PROC_STATUS = 'Approved'"))) 

auf die Bericht-Abfrage, ich setze so:

$P!{query} 

es in der Lage, das Feld aus der Datenbank ohne Fehler zu laden.

SALESMAN 
SALES_AMOUNT 
SALES_TYPE 

, aber wenn ich es eine Vorschau, den Fehler geben: nicht von String werfen kann

eine Idee zu lösen Boolean?

Answer 1

Sie müssen die anderen Teile in der Verlängerung geklam- mert

(new String("all").equals($P{pSales_type}) ? "SELECT .... : 
((new String("rq").equals($P{pSales_type}) ? "SELECT .... : 
((new String("wo").equals($P{pSales_type}) ? "SELECT .....  ))
