php - Laravel maatwebsite excel包导入2000+行导致1390代码错误

Question

我有 4 个 Excel 文件，每个文件包含 1000 行。我将其合并并使其为 4000，这样我可以节省一些时间。但是，如果我导入合并的文件，它会返回错误一般错误:1390 准备好的语句包含太多占位符。但是当我只将它们插入一个时，它就起作用了。我不知道为什么它返回这样的错误，它们甚至在每一列中都有相同的值。有人可以告诉我如何处理这个错误吗？我们将提供帮助。非常感谢

我正在使用 laravel maatwebsite excel 包。

我的导入代码

public function import(Request $request)
    {
        if($request->hasFile('template')){
            $path = $request->file('template')->getRealPath();
            $data = \Excel::load($path)->get();

            if($data->count() > 0){
                $rows = $data->toArray();

                foreach ($rows as $row) {

                    $level = '';

Answer 1

使用 laravel insert() 方法插入的记录数不能超过 1000 条。如果你想达到预期的输出，那么你可以使用php的array_chunk函数或laravel的collection。 例如使用 array_chunk :

$chuncked = array_chunk($inserts, 1000);

foreach($chuncked as $insert){
   \DB::table('xp_pn_ura_transactions')->insert($insert);
}
