使用 MySQL PHP 更新批量项目

Question

我试图用一个单一的批量查询更新我的数据库 table 中的 3,000 多条记录，但是我运行进入了一个带有我的 id 数组的路障。想知道我在这里做错了什么？

这是我收到的错误：

check the manual that corresponds to your MySQL server version for the right syntax to use near ') END WHERE InventoryID IN (recs8AFaXZWvAlDIP,recvwDSutfQ66Jtj8,recQ1LODI7ED1FRT'

代码如下：

$sql_connect = mysqli_connect("blah", "blah", "blah", "blah");

$sql = "SELECT inventory.MCategoryID, inventory.InventoryID, inventory.SCategoryID, inventory.ManufacturerID, maincategory.CategoryName as mainCategoryNameMatch, subcategory.SubCategoryName as subCategoryNameMatch, manufacturer.ManufacturerName as manufacturerNameMatch FROM inventory LEFT JOIN maincategory ON inventory.MCategoryID = maincategory.AirTableID LEFT JOIN subcategory ON inventory.SCategoryID = subcategory.AirTableSubCategoryID LEFT JOIN manufacturer ON inventory.ManufacturerID = manufacturer.AirTableManufacturerID ORDER BY CambridgeID";
$doit = mysqli_query($sql_connect, $sql) or die(mysqli_error($sql_connect));
$updateSQL = '';
$uniqueIDArray = [];
$bulkUpdate = '';
$bulkID = '';
while($results = mysqli_fetch_object($doit)){
    $mainCategoryNameResult = $results->mainCategoryNameMatch;
    $subCategoryNameResult = $results->subCategoryNameMatch;
    $manufacturerNameResult = $results->manufacturerNameMatch;
    $uniqueID = $results->InventoryID;      
    $uniqueIDArray[] = $uniqueID;


    $updateSQL .= "WHEN '$uniqueID' THEN '$mainCategoryNameResult'\n";


}
//echo $updateSQL;
$id_list = implode(',', $uniqueIDArray);    
echo "UPDATE inventory SET MainCategoryNameMatch = (CASE InventoryID $updateSQL END) WHERE InventoryID IN ($id_list)<br/>";
if (mysqli_query($sql_connect, "UPDATE inventory SET MainCategoryNameMatch = (CASE InventoryID $updateSQL) WHERE InventoryID IN ($id_list)") or die(mysqli_error($sql_connect))){
    echo $updateSQLStatement;
}

如有任何帮助，我们将不胜感激。

ID 是字符串 - 它们必须用引号引起来：

$id_list = '"' . implode('","', $uniqueIDArray) . '"';
