我使用準備好的發言改善，我做一個查詢語句，但它產生的錯誤：數參數的錯誤準備
Wrong number of parameters
查詢如下：
$start = new DateTime('first monday of January 2016');
$end = new DateTime('last day of December 2016');
$sql = "SELECT ".$generalLand."
product AS product,
Week AS label,
ROUND(SUM(harvest)/SUM(production),2) AS value
FROM (
(
SELECT ".$fieldLand."
pr_products.product,
CONCAT(YEAR(:dates),'-', LPAD(WEEK(:dates1),2,'0')) AS Week,
SUM(IF(sw_sowing.type = 'SW', sw_sowing.quantity,0)) AS PlantSowing,
SUM(IF(ROUND(DATEDIFF(TIMESTAMPADD(DAY,(6-WEEKDAY(:dates2)),:dates3), sw_sowing.date)/7) >= pr_products.week_production AND sw_sowing.type = 'SW',sw_sowing.quantity,0)) AS production,
0 AS Harvest
FROM (
SELECT max(sw_sowing.id) AS id
FROM sw_sowing
WHERE sw_sowing.status != 0
AND sw_sowing.date <= TIMESTAMPADD(DAY,(6-WEEKDAY(:dates4)),:dates5)
GROUP BY sw_sowing.id_production_unit_detail
) AS sw
INNER JOIN sw_sowing ON sw_sowing.id = sw.id
INNER JOIN pr_products ON pr_products.id = sw_sowing.id_product
INNER JOIN pr_varieties ON sw_sowing.id_variety = pr_varieties.id
".$innerSowing."
WHERE pr_varieties.code != 1
AND sw_sowing.id_product = 1
AND sw_sowing.status = 100
AND sw_sowing.id_tenant = :id_tenant
".$consultSowing."
GROUP BY pr_products.product
HAVING plantSowing > 0
ORDER BY pr_products.product
)
UNION ALL
(
SELECT ".$fieldLand."
pr_products.product,
CONCAT(YEAR(:dates6),'-', LPAD(WEEK(:dates7),2,'0')) AS Week,
0 AS plantSowing,
0 AS Production,
SUM(pf_harvest.quantity) AS Harvest
FROM pf_harvest
INNER JOIN pr_products ON pr_products.id = pf_harvest.id_product
INNER JOIN pr_varieties ON pr_varieties.id = pf_harvest.id_variety
INNER JOIN pf_performance ON pf_performance.id = pf_harvest.id_performance
".$innerHarvest."
WHERE pf_harvest.date BETWEEN TIMESTAMPADD(DAY,(0-WEEKDAY(:dates8)),:dates9)
AND TIMESTAMPADD(DAY,(6-WEEKDAY(:dates10)),:dates11)
AND pr_varieties.code != 1
AND pf_harvest.id_product = 1
AND pf_performance.status = 100
".$consultHarvest."
AND pf_harvest.id_tenant = :id_tenant1
GROUP BY pr_products.product
ORDER BY pr_products.product
)
) AS sc
GROUP BY product, label
ORDER BY label";
$statement = $this->db->prepare($sql);
$id_tenant = $this->getIdTenant();
foreach($datePeriod AS $dates){
$values = [
':dates' => $dates->format('Y-m-d'),
':dates1' => $dates->format('Y-m-d'),
':dates2' => $dates->format('Y-m-d'),
':dates3' => $dates->format('Y-m-d'),
':dates4' => $dates->format('Y-m-d'),
':dates5' => $dates->format('Y-m-d'),
':dates6' => $dates->format('Y-m-d'),
':dates7' => $dates->format('Y-m-d'),
':dates8' => $dates->format('Y-m-d'),
':dates9' => $dates->format('Y-m-d'),
':dates10' => $dates->format('Y-m-d'),
':dates11' => $dates->format('Y-m-d'),
':id_tenant' => $id_tenant,
':id_tenant1' => $id_tenant
];
$result = $this->db->executePrepared($statement , $values);
}
我理解這是因爲我在查詢中有多少個綁定。
每個:date是相同的日期，但我把一個不同的值，因爲變量不能重複。
我也試圖改進我的查詢，因爲我用一個循環顯示了我每年的每個星期一的日期以及我放入查詢的日期。
爲此，我以這種方式
諮詢如果誰能給我一個建議，我將不勝感激。
問候！
