我有两个独立的查询:
查询1(此查询从我的表中获取所有图库):
$showgallerys = mysqli_query($con,"SELECT * FROM canais");
while($row = mysqli_fetch_array($showgallerys)) {
echo '<div class="canal-nome">'.$row['nome'].'</div>;
查询2(此查询计算每个类别的照片数量):
$q="SELECT categoria, COUNT(titulo) FROM galerias GROUP BY categoria ";
$res=mysqli_query($con,$q);
while($row = mysqli_fetch_array($res)){
echo '
('. $row['COUNT(titulo)'] .')';
}
我需要显示图库的名称(查询1)和照片数量(查询2)
喜欢这个图库名称(30)
这是第一张表的结构(称为 canais ):
id | nome | htd | imagem | thumb |
1 | Gallery Nature | nature | face.jpg | thumb.jg |
2 | Gallery Peoples | people | face.jpg | thumb.jg |
3 | Gallery Animals | animal | face.jpg | thumb.jg |
这是第二张表的结构(称为 galerias )
id | titulo | foto | thumb | data | categoria |
1 | Sun | sun.jpg | sun-thumb.jpg | now | nature |
2 | Moon | mon.jpg | mon-thumb.jpg | now | nature |
3 | Tree | tree.jpg| tre-thumb.jpg | now | nature |
4 | Woman | wman.jpg| wman-thumb.jpg | now | people |
5 | Girl | gran.jpg| gr-thumb.jpg | now | people |
6 | leaf | lea.jpg | leaf-thumb.jpg | now | nature |
7 | dog | dog.jpg | dog-thumb.jpg | now | animal |
在这种情况下,我需要显示如下结果:
Gallery name --> Gallery Nature (4) <-- Number of occurrences
Gallery name --> Gallery People (2) <-- Number of occurrences
Gallery name --> Gallery Animal (1) <-- Number of occurrences
作为画廊的名称必须通过&#34; canais&#34;表格和出现次数必须来自&#34; galerias&#34;表格基于&#34; categoria&#34;柱。有人可以帮我解决吗?
答案 0 :(得分:2)
以下查询将为您提供帮助
SELECT a.nome AS gallery ,COUNT(b.titulo) AS photos
FROM canais a INNER JOIN galerias b ON a.htd = b.categoria
GROUP BY a.nome
