我将javascript代码用作TamilNadu地图的外部文件,并将以下SQL代码用于pentaho的表组件。

现在,通过单击按钮,我想通过将javascript变量作为参数来显示表格。

javascript代码:-

var js_city = 'coimbatore';

SQL代码:

SELECT 
     CONCAT(UCASE(LEFT(A, 1)), SUBSTRING(A, 2)) AS 'Service Center Name',
    CONCAT(UCASE(LEFT(B, 1)), SUBSTRING(B, 2)) AS 'State',
     CONCAT(UCASE(LEFT(C, 1)), SUBSTRING(C, 2)) AS 'Status'
       FROM
    (SELECT 
        LOWER(A.service_center_name) AS A,
        A.status AS C,
        LOWER(C.branch_name) AS 'B'
    FROM
        customers A
    INNER JOIN ascs B ON A.serv_cent_mob_no = B.contact_number
    INNER JOIN branches C ON B.branch_id = C.id
    GROUP BY A.service_center_name , A.status , C.branch_name) AS Issue
       WHERE B=${sqlcity};

如何在pentaho中将“ js_city”变量作为“ sqlcity”参数传递?

例如:

1。最初将 countryName()定义为外部js。 2.简单的参数名称是: cityPara 3.转到pentaho cde->组件面板->脚本->功能->您必须调用外部js值并设置参数值。  功能脚本:

function countryName(){ 
    dashboard.fireChange('${p:cityPara}',js_city);
    console.log("countryName :", js_city);
}
