如何在SQL/PHP中加入multi-select

还没有找到一个很好的答案。要运行下面的两个select语句，我需要添加什么。我尝试了Union ALL和其他一些功能，但它不返回数据。任何帮助都将不胜感激。 试着用桌子来做这个。

您发布的SQL语句不是有效的SQL，这就是它不返回任何数据的原因。如果生成的查询有效，则UNION ALL应该可以工作。列名必须匹配，联合才能工作

这将返回您正在查找的数据：

SELECT 
  bin_loc as [Yard Location],
  status as [Status],
  item_no as [Equipment]
FROM location 
WHERE type like 'YARD'

UNION ALL

SELECT
  bin_loc as [Yard Location],
  status as [Status],
  item_no as [Equipment]
FROM location 
WHERE type like 'DOCK'

我最终创建了两个表来完成我需要的工作，而不是试图在一个表中全部完成，因为字段需要以特定的顺序显示。包括像我这样的新手的php和SQL。 谢谢你的帮助

请看或。不，除非您使用mysqli\u multi\u查询，否则您将无法使用一条语句运行两个查询。但是，使用UNION ALL应该可以工作，或者将它们作为单独的查询运行。虽然由于您从同一个表中获得相同的信息，请使用OR，如果您希望对它们进行分组，请使用ORDER BYselect bin_loc作为[Yard Location]，status作为[status]，item_no作为[Equipment]，从输入'Yard'，DOCK'的位置输入。我认为应该这样做。我只看到一个SELECT语句。另一个在哪里？我建议您修改示例，只包含SQL，因为PHP与这个问题无关。
