上传到数据库时检查重复

Question

我需要在上传包含一些详细信息的Excel文件时在现有表格中找到重复的详细信息，我需要通过电话号码和客户名称查找。我正在使用mattexcel将数据上传到数据库中。

我不想插入那些细节，如果它在那里，但其他细节必须插入该表

Answer 1

选项1.您可以在迁移中添加唯一值组合。

Schema::table('your_table_name', function (Blueprint $table) {
            $table->unique(['phone ','customername ']);
});

这不会让您为这些列组合插入相同的组合值，但是它也会导致错误停止导入功能。

选项2（更好）。 检查值是否已经退出并忽略该列的导入。

$old_customer = Regiter::where('phone', $row['phone'])->where('customername', $customername )->first();
        //Inser only if customer not found
        if(is_null($old_customer)) 
        {
            //INSERT QUERY
        }

要减少查询次数，您可以使用单个查询来拨打姓名和电话，或使用任何其他优化技巧。
