PHP更新MySQL中错误的行数

Question

This SQL用于更新大约334行。但是，当PHP执行以下相同的SQL时：

$updateCollectsProductsQuery = $wpdb->prepare($preparedStatement, $queryParameters);
$wpdb->query($updateCollectsProductsQuery);

仅50行被更新。有人知道为什么会这样吗？我不知道执行更新的PHP或Wordpress的限制吗？

更新1

$preparedStatement看起来像this，而$queryParameters看起来像this，而$updateCollectsProductsQuery是first link。

更新2

PHP仅更新50中定义的前IN (prdouct_ids)个产品ID，而wp_wps_collects中的其余行将被删除。简而言之，此查询334以前的SELECT * FROM wp_wps_collects WHERE collection_id = 99380101233行现在只有50行。这是PHP的一些非常奇怪的行为。我只是在更新。

更新3

我将查询减少到仅51个可能要更新的行，而查询仍然仅更新50行，然后删除表wp_wps_collects中的其他284行。这是仅传递给$wpdb->query 51行进行更新的wp_wps_collects时查询的样子：
