Bulk Insertion in Laravel using eloquent ORM

Bulk Insertion in Laravel using Eloquent ORM: Easy Solutions for Common Issues 😎🛠️

Performing bulk database insertions in Laravel using Eloquent ORM can sometimes be a bit tricky, especially when dealing with large datasets. In this blog post, we will address the common issue of mixing named and positional parameters in a bulk insert operation and provide you with easy solutions to overcome this problem. So, let's dive in! 💪

The Challenge: Mixing Named and Positional Parameters ❌

In the given context, the user is trying to insert multiple records into the database by looping through an XML document. However, the resulting SQL query is causing the following error: SQLSTATE[HY093]: Invalid parameter number: mixed named and positional parameters.

The Solution: Using Eloquent's insert() Method 🚀

To perform bulk insertions using Eloquent ORM in Laravel, you can leverage the insert() method, which allows you to insert multiple records with a single database query. The key here is to properly construct the array of data that will be passed to the insert() method. Let's see how this can be done!

$sXML = download_page('http://remotepage.php&function=getItems&count=100&page=1');
$oXML = new SimpleXMLElement($sXML);
$data = [];

foreach($oXML->results->item->item as $oEntry) {
    $data[] = [
        'first_name' => $oEntry->firstname,
        'last_name' => $oEntry->lastname,
        'date_added' => date("Y-m-d H:i:s")
    ];
}

DB::table('tbl_item')->insert($data);

By using the insert() method, you can pass an array of data where each element represents a row to be inserted into the database. In this case, we loop through the XML elements and build an array called $data with the desired column values.

The Result: Say Goodbye to SQLSTATE Errors! 🎉

By utilizing the insert() method and constructing the data array correctly, you can effectively perform bulk insertions without encountering any SQLSTATE errors. Laravel takes care of mapping the array elements to the corresponding table columns, ensuring a smooth insertion process.

Take it to the Next Level: Speed up Bulk Insertions with Chunking ⚡

If you're dealing with exceptionally large datasets, you might face memory issues when trying to insert all the records at once. Laravel provides a convenient solution by allowing you to chunk the data array into smaller pieces and process them iteratively using the chunk() method. This helps improve memory usage and prevents performance bottlenecks.

Here's an example of how to utilize the chunk() method:

$sXML = download_page('http://remotepage.php&function=getItems&count=100&page=1');
$oXML = new SimpleXMLElement($sXML);

DB::table('tbl_item')->chunk(200, function ($data) {
    $insertData = [];

    foreach($data->results->item->item as $oEntry) {
        $insertData[] = [
            'first_name' => $oEntry->firstname,
            'last_name' => $oEntry->lastname,
            'date_added' => date("Y-m-d H:i:s")
        ];
    }

    DB::table('tbl_item')->insert($insertData);
});

In this example, we use the chunk() method to process 200 records at a time. You can adjust the chunk size based on your data size and memory availability.
