Question

我试图将2个SQL查询一个用于名称：

$query = "SELECT * FROM register WHERE name LIKE '" .$name ."'ORDER BY id DESC";

和一个得到$和$到：

$sql = "SELECT * FROM register WHERE time BETWEEN ('$from') AND ('$to')";

您能否建议如何将这两个查询组合起来，以显示所选择的名称以及从中选择的名称，以及仅显示所选名称的所有结果，而不显示from和to？

Answer 1

您可以使用Union来合并两个查询的结果

SELECT * FROM register WHERE name LIKE '" .$name ."'
union all
SELECT * FROM register WHERE time BETWEEN ('$from') AND ('$to')

Answer 2

SELECT * FROM register WHERE time BETWEEN @from AND @to
UNION
SELECT * FROM register WHERE name LIKE @name ORDER BY id DESC

Answer 3

可以使用UNION完成此操作，也可以使用OR条件：

SELECT *
FROM register
WHERE name LIKE '" .$name ."'
    OR time BETWEEN ('$from') AND ('$to')
ORDER BY id DESC;

Answer 4

    SELECT * FROM register WHERE name LIKE '" .$name ."' 
          OR time BETWEEN ('$from') AND ('$to')
    ORDER BY id DESC

Answer 5

你的问题不清楚但仍可以尝试这样的事情

$query = "SELECT * FROM register WHERE name LIKE '" .$name ."'
OR (time BETWEEN ('$from') AND ('$to')) ORDER BY id DESC";

Answer 6

这就是我所追求的，感谢我的Oracle程序员，你知道你是谁，我想分享：

$query = "SELECT * FROM register WHERE name LIKE '" .$name ."' and time between ifnull(timestamp('$from'),time) and ifnull(timestamp('$to'),time) ORDER BY id DESC";

如何将2个SQL查询放在一起？
