Question

我尝试运行包含局部变量和循环的查询。但是Fusio / Doctrine在执行时返回空/错误。

示例（空结果或布尔值）：

$sum = $connection->fetchAll("declare @dateFrom DATETIME=CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)));
declare @dateTo DATETIME=CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()));
declare @dateFromtmp DATETIME=@dateFrom;

declare @tmpDate table(Dates  DATETIME);

WHILE (@dateFromtmp <= @dateTo)
BEGIN
    insert into @tmpDate values(@dateFromtmp)
    SET @dateFromtmp = DATEADD( DAY,1,@dateFromtmp)
END;

SELECT @dateFrom;
 ");
$type = "is " . gettype($sum);
$count = count($sum);
return $response->build(200, [], [
    'type'=>$type,
    'count'=>$count,
    'summary' => $sum,
]);

返回：

{
    "type": "is array",
    "count": 0,
    "summary": []
}

在查询下面运行没有问题：

$sum = $connection->fetchColumn("declare @dateFrom DATETIME=CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)));
declare @dateTo DATETIME=CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()));
declare @dateFromtmp DATETIME=@dateFrom;

declare @tmpDate table(Dates  DATETIME);

SELECT @dateFrom;
 ");
$type = "is " . gettype($sum);
$count = count($sum);
return $response->build(200, [], [
    'type'=>$type,
    'count'=>$count,
    'summary' => $sum,
]);

返回：

{
    "type": "is string",
    "count": 1,
    "summary": "2017-08-01 00:00:00.000"
}

我怀疑这与循环有关。有没有办法在Fusio中运行此查询。？

在Doctrine - Fusio中使用declare和loop执行sql查询
