<p>以上应用可以通过参数是否有传递来实现开关代码段的效果, 有些场景可能还希望通过参数值来进行代码段的开关
|
|
如下代码可以实现当传递参数type=1 或 type=2 时执行不同的代码段
|
|
使用 “$参数__值” 的方式做为开关</p>
|
|
<pre tabindex="0"><code>/* select count(1) as qty from tablename1 $type__1*/
|
|
/* select count(1) as qty from tablename2 $type__2*/
|
|
</code></pre><p>再比如
|
|
当参数D传值为"月份"时是统计2022年按月的统计,
|
|
传"日期"时统计的是2022年10月按天的统计</p>
|
|
<pre tabindex="0"><code>select $D, count(1) as qty from tablename
|
|
where 1 = 1
|
|
/* and year='2022' -- $D__日期 $D__月份 */
|

/* and month='10' $D__日期 */

group by

$D

方法如下格式, 你可以在sql编辑器的最上方写上 /* {xxxxxx} */,

会默认在开发调试模式下取这些参数, 在用户模式下会忽略

<ul>
|
|
<li>你可以从url传入参数, 在url上加入 &param={“参数名”:“参数值”}</li>

<li>在图形联动的点击过程中会自动传递参数， 具体参考联动相关文档</li>

<blockquote>
|
|
<p>TIPS
|
|
当设定参数后, 联动过程dataset的缓存功能失效, 所以不要让带参数的查询设计得太慢
|
|
参数如果存在一些非法字符可能会有问题, 比如参数中不可以有#号</p>
