你好，正如我昨天讨论的从多个表中检索数据到

多个查询，但我得到了很多关于将表连接到一个查询中的好建议。

实际上在这里我将多个表加入到一个查询中，但我想检索数据

仅从两个表中，T1 是属性，T2 是相关属性的图像。

我做到了，但它给出了一个我找不到的错误。

从行中删除 ' , '

pds.PDName,

并且最好尝试加入任何两个表，例如

FROM properties
JOIN provinces ON provinces.PropertyId = properties.provinceId

您已将,From 子句之前的 the 删除。在这儿

喜欢它：

districts.DistrictName,
pds.PDName

FROM properties, provinces, districts, pds, propertyimages
