Mysql bulk insert not inserting all data

Question

I have to insert many data from excel to a table (about 4000 rows ) throught Ajax inside a loop i use :

$query = "INSERT IGNORE INTO ".$params["table"]." (".$colonnes_string.") VALUES (".$row.")";

This query works fine but it insert only 1000 rows of 4000, may be some insert have error why i set IGNORE statement, but it still not insert above 1000 rows.

How can i skip insert error and continue the query ?

Thank you.

请使用INSERT ... ON DUPLICATE KEY UPDATE语法而不是IGNORE这是指向类似问题的链接https://softwareengineering.stackexchange.com/questions/238472/how-to-insert-update-a-large-amount-of -将数据导入mysql-php

You can insert multiple rows with that syntax :

$query = "
    INSERT INTO some_table 
        (column_name) 
    VALUES 
        ('value'),
        ('another value'),
        ('and again'),
        ...
        ('a last one');
";

So, you'll have to build the query with all your VALUES and then INSERT them all at once.

ie :

// Set the first part of the query with table name and column(s)
$query = "INSERT INTO some_table (some_column) VALUES ";

foreach ($rows as $row) {
    // concatenate the query with values in a loop
    $query .= "(".$row."),";
}

// replace last comma with semi-column to get the right syntax
$query = substring($query, 0, -1).";";

Hope it helps.
