先月のレコードのみを表示するサブクエリを追加しようとしています。チェックする必要のある列はDateOfCheckと呼ばれ、自動TimeStamp列です。

私はこれを持っています：

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

メインクエリに配置すると構文エラーが発生します。

また、私は（私は初心者です）これは、先月を見る必要があるときに、今日から先月を見ているだけだと思います。

また、現在の暦月のすべてのレコードを呼び出すには、個別のサブクエリが必要です。

さて、完全なクエリ（これはおそらくひどく非効率的なコードであることに気づいています-私は何かを一緒に石畳にしようとしている完全な初心者だと言ったので！）は以下です、日付を入力しようとするまではうまくいきます上記のサブクエリ。

$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"){

問題は、最終的なクエリが「SELECTSELECT」で始まることです。あなたはそれをこのように組み立てます：

"SELECT $SelectedMonth, $CA001 ..."

で$selectedMonth始まります：

"select * from Data_Table where ..."

だからあなたは得ています：

"SELECT select * from Data_Table where ..."

もう1つの問題は、これが複数の列を選択する唯一のサブクエリであるため、このような大規模なクエリに構文を統合するのが難しくなることです。1つのテーブルからのみ選択しているため、全体を1つの大きなSELECTに作り直す必要があります。これが非常に簡単なアイデアです（1つの選択、サブクエリなし）：

$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";

理論的根拠：上記のコードは、簡単に言えば、これを行います：

  1. 選択する「列」のPHP配列を作成します（$cols）
  2. それらの列を組み立てます（implode）
  3. 連結を介して、必要に応じてWHERE adGROUPBY句を追加します。

最もトリッキーな部分はsprintfです。これは、phpのマニュアルページで詳しく説明されています。基本的に、文字列を解析し、その中に変数のフォーマットされたバージョンを配置します。フォーマット指定子は「この%i引数は整数になります」と言います。ただし、追加の処理を行わないと、列のエイリアスは「CA001」ではなく「CA1」になります。幸いなことに、sprintfには必要なものがあり、%03i「intを少なくとも3桁の幅にし、（スペースではなく）0で埋める」と言っています。したがって、たとえばこれは、COUNT(CA%03iResult)23を超えると、結果になりCOUNT(CA023Result)ます。

スクリプトについては、このコースを検討することを強くお勧めします。桁違いにパフォーマンスが高く、エラーが発生しにくくなっています（たとえば、実行フォークが2つの場所にあるため、いずれかのパス（たとえば、$ product）にSQLエラーが発生してもすぐには気付かない場合があります。 = OPのすべてのクエリに他のクエリのカンマがありません。簡単な見落としですが、自動テストを頻繁に実行していない場合は見逃しがちです）。

サブクエリと先月の問題に関しては、次date_format(curdate() - interval 1 month,'%Y-%m-01 00:00:00')のように先月全体を取得するために使用できます。

select *
  from   Data_Table
  where DateOfCheck between date_format(curdate() - interval 1 month,'%Y-%m-01 00:00:00')
     and date_sub(curdate(), interval 1 day)
