WDA基础十八:Select option配置

为了省代码。。。为了方便管理WDA的查询条件。。。

首先建配置表：

说明：

上面的KEY基本都是维护的维度，可以根据销售组织，根据用户组，根据组件，根据SELECT OPTION的不同。。。等等，可以根据情况而定。

COMPONENT_NAME:wda组件名，不同的组件配置不同。

SELOPTION：SELECT OPTION名，不同的SELECT不同配置。

ATTRIBUTE：字段名，这里按照表字段名来处理的，方便后面做动态SQL。

TABNAME：表名，需要查的字段对应的数据库表，也是方便后面动态SQL。

DATAELEMENT：数据元素，创建OPTION的对象。

TEXT：字段标签，可以是OTR翻译文本，也可以是固定文本。

DISP_INDEX：SELECT条件的位置。

VISIABLE：查询条件是否可见。

MANDATORY：查询条件是否必填。

NO_EXTENSION：没有扩展选项
NO_INTERVALS：没有范围选择
AS_CHECKBOX：查询条件是CHECK BOX
AS_DROPDOWN：查询条件是下拉

SELECT OPTION初始化：

看看效果：

输入查询条件，看处理结果：

这里没配TABLENAME，都是默认的：

 

 可以根据TABLENAME分到不同的动态SQL里，然后加到常规SQL中。
