MIPS：“lw”指令路径(MIPS: “lw” instruction path)

 从讲义：   
 根据我的理解，黑点是否表示二进制位被复制到两条路径向前移动？  
 例如，指令位I[20-16]应该进入Read register 2和Write register 。 最后，由于MUX选择1，最终没有使用Read data 2 。  
 我的教授是否选择不将红线绘制到Read register 2路径以强调最重要的路径？ 或者Read register 2之前的黑点是否能够关闭不相关的数据路径？ 

From lecture notes:  
from what I understand, doesn't the black dots indicate the binary bits is being copied to both paths moving forward?  
For example, instruction bits I[20-16] should be going into the Read register 2 and Write register. It's just that in the end, the Read data 2 is not being used due to the MUX selecting 1.  
Did my prof choose not to draw the red lines going to the Read register 2 path just to emphasize on the most significant path? Or does the black dot before Read register 2 have the ability to close off irrelevant data path?

 您可以将输出存储在变量中，如下所示：  
<?php
    $output = '';
    $webtech = article_custom_field('web-tech');
    if ( !empty($webtech) ) :
        $output .= '<div class="tech-title">Technologies:</div>'
            . '<ul class="tech-ul">' . $webtech . '</ul>';
    endif;

    $url = article_custom_field('site-url');
    if(!empty($url)) :
        $output .= '<div class="site-url"><a href="' . $url . '" target="_blank">Visit</a></div>';
    endif;

    if($output != ''):
        echo '<div class="tech-list">';
        echo $output;
        echo '</div>';
    endif;
?>
 
 这样，只有在输出变量中设置了某些内容时，它才会显示任何内容。  
 这会解决您的问题吗？ 

You could store your outputs in a variable, like so: 
<?php
    $output = '';
    $webtech = article_custom_field('web-tech');
    if ( !empty($webtech) ) :
        $output .= '<div class="tech-title">Technologies:</div>'
            . '<ul class="tech-ul">' . $webtech . '</ul>';
    endif;

    $url = article_custom_field('site-url');
    if(!empty($url)) :
        $output .= '<div class="site-url"><a href="' . $url . '" target="_blank">Visit</a></div>';
    endif;

    if($output != ''):
        echo '<div class="tech-list">';
        echo $output;
        echo '</div>';
    endif;
?>
 
This way, only when there is something set in your output variable, will it show anything. 
Does this solve your problem?

虽然你可以做一个cross join来得到你想要的东西，但我猜想FROM和其余的WHERE子句是相同的。在这种情况下，只需进行条件聚合： SELECT SUM(CASE WHEN dbo.SEM_AGENT.AGENT_VERSION like '%11.%' THEN 1 ELSE 0 END) as Number_of_SEP11_clients, SUM(CASE WHEN dbo.SEM_AGENT.AGENT_VERSION like '%12.%' THEN 1 ELSE 0 E ...
