mysql - MYSQL 日期/时间子查询的语法错误

标签 mysql sql datetime

尝试添加仅显示上一个日历月的记录的子查询。它需要检查的列称为 DateOfCheck，是一个自动时间戳列。

我有这个:

$SelectedMonth = "
  select *
  from   Data_Table
  where  DateOfCheck >= date_sub(curdate(), interval 1 month)
     and DateOfCheck <= date_sub(curdate(), interval 1 day)
";

当我将其放入主查询中时，出现语法错误。

另外，我认为(我是菜鸟)这只是查看从今天开始的最后一个月，当我需要它来查看最后一个日历月时。

我还需要一个单独的子查询来调用当前日历月中的所有记录。

好吧，完整的查询(我知道这可能是非常低效的代码 - 正如我所说，我是一个试图将一些东西拼凑在一起的完全菜鸟!)如下，它工作正常，直到我尝试输入上面的日期子查询。

$Area = $_POST['Area'];
$product = $_POST['Product'];
$AverageScore = ("ROUND(AVG(Score),1)AS 'Avg <br/> Score'");
$AverageAutofails = ("ROUND(AVG(Autofails),1)AS 'Autofails <br/> per Check'");
$ProductTotal = "SELECT (COUNT (CA001Result) from Data_Table WHERE Product ='$product')";




$SelectedMonth = "select * from Data_Table where DateOfCheck >= date_sub(curdate(), interval 1 month) and DateOfCheck <= date_sub(curdate(), interval 1 day)"; 
ECHO $SelectedMonth;

if ($product == "All"){

感谢任何帮助，干杯!

最佳答案

问题是最终查询将以“SELECT SELECT”开头。你可以像这样组装它:

"SELECT $SelectedMonth, $CA001 ..."

和 $selectedMonth 开头为: 

"select * from Data_Table where ..."

所以你得到:

"SELECT select * from Data_Table where ..."

另一个问题是，这是唯一一个选择多个列的子查询，这使得语法更难集成到如此庞大的查询中。由于您只从一个表中进行选择，因此应该将整个事情重新设计为一个大型的单个 SELECT。这是一个非常简单的想法(一次选择，无子查询):

$cols[] = "ROUND(AVG(Score),1)AS 'Avg <br/> Score'";
$cols[] = "ROUND(AVG(Autofails),1)AS 'Autofails <br/> per Check'";
$cols[] = "(COUNT (CA001Result)";

// Note: %03i will format 3 as 003
$columnFormat = "100 * SUM(IF(CA%03iResult='Fail', 1, 0)) / COUNT(CA%03iResult) AS CA%03i";
for($i = 1; $i <=28; $i++) {
  $cols[] = sprintf($columnFormat, $i, $i, $i);
}

$fieldList = implode(', ', $cols);
$sql = "SELECT " . $fieldList;
$sql .= " FROM Data_table WHERE Area='$Area' AND DateOfCheck BETWEEN CURDATE() - INTERVAL 1 MONTH AND CURDATE() - INTERVAL 1 DAY";
if($product != 'ALL') {
  $sql .= " AND Product = '$product'";
}
$sql .= " GROUP BY Area";

基本原理:上面的代码，用最简单的术语来说，是这样做的:

  1. 构建一个由“列”组成的 PHP 数组来选择 ($cols)
  2. 组装这些列(内爆)
  3. 通过串联适当添加 WHERE ad GROUP BY 子句。

最棘手的部分是 sprintf，it's php manual page 对此有很好的解释。 。本质上，它解析一个字符串并将变量的格式化版本放入其中。 %i 格式说明符表示“此参数将是一个整数”。但是，如果不进行额外处理，您的列别名将为“CA1”而不是“CA001”。幸运的是，sprintf 有我们需要的东西，%03i 说“让 int 至少有 3 位数字宽，并用 0 填充(而不是空格)”。因此，例如:COUNT(CA%03iResult) 当传递 23 时，将得到 COUNT(CA023Result)。

强烈建议您考虑将本类(class)用于您的脚本。它的性能要高出几个数量级，并且不太容易出错(例如，由于您的执行 fork 在两个位置，因此当您在其中一个路径中引入 SQL 错误时，您可能不会立即注意到(例如，您的 $product = OP 中的所有查询都缺少另一个查询中的逗号，这是简单的疏忽，但如果您不经常运行自动化测试，则很容易错过)。
