How to Do Large Batch Insert In Codeigniter?

7 minutes read

To perform a large batch insert in CodeIgniter, you can use the insert_batch() method provided by the CodeIgniter database class. This method allows you to insert multiple rows of data into a database table in a single query, which can greatly improve performance when dealing with large datasets.


To use the insert_batch() method, you first need to create an array of data where each element represents a row to be inserted into the table. Each element in the array should be an associative array with key-value pairs where the keys are the column names in the database table.


Once you have constructed your array of data, you can pass it to the insert_batch() method along with the name of the table you want to insert the data into. CodeIgniter will then generate and execute the appropriate batch insert query for you.


Here is an example of how you can use the insert_batch() method in CodeIgniter:

$data = array(
    array(
        'column1' => 'value1',
        'column2' => 'value2',
        'column3' => 'value3'
    ),
    array(
        'column1' => 'value4',
        'column2' => 'value5',
        'column3' => 'value6'
    ),
    // Add more row data as needed
);

$this->db->insert_batch('table_name', $data);


By using the insert_batch() method, you can efficiently insert a large amount of data into your database table with just a single query, reducing the number of queries executed and improving the overall performance of your application.


How to set up a database connection for large batch insert in Codeigniter?

In Codeigniter, you can configure a database connection for large batch inserts by following these steps:

  1. Open the database.php configuration file located in /application/config/ folder.
  2. Set up a new database connection by defining a new group in the $db['default'] array. For example, you can create a new connection named large_inserts like this: 
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16

$db['large_inserts'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'your_username',
    'password' => 'your_password',
    'database' => 'your_database',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);


  1. Once you have set up the new database connection, you can load this connection in your controller or model using the following code:
1

$this->load->database('large_inserts');


  1. After loading the database connection, you can use Codeigniter's Active Record class or Query Builder class to perform large batch inserts into the database. Here's an example of how you can insert multiple records in a single query:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

$data = array(
    array(
        'title' => 'My title 1',
        'content' => 'My content 1'
    ),
    array(
        'title' => 'My title 2',
        'content' => 'My content 2'
    ),
    // Add more records here
);

$this->db->insert_batch('my_table', $data);


With this setup, you can efficiently perform large batch inserts in Codeigniter using a separate database connection specifically configured for this purpose.


How to perform a rollback in case of a failed large batch insert in Codeigniter?

In Codeigniter, you can perform a rollback in case of a failed large batch insert by using transactions. Here's how you can do it:

  1. Start a transaction at the beginning of the batch insert process using the $this->db->trans_start() function. This will begin a transaction and disable auto-commit mode.
  2. Perform the batch insert operation using $this->db->insert_batch('table_name', $data). This will insert the data into the database in a single query.
  3. Check if the batch insert was successful by using $this->db->affected_rows(). If the affected rows are greater than 0, commit the transaction by using $this->db->trans_complete(). This will save the changes to the database.
  4. If the batch insert fails, rollback the transaction using $this->db->trans_rollback(). This will undo all the changes made during the transaction.


Here's a code example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

$this->db->trans_start();

// Perform batch insert
$this->db->insert_batch('table_name', $data);

if ($this->db->affected_rows() > 0) {
    // Commit transaction
    $this->db->trans_complete();
} else {
    // Rollback transaction
    $this->db->trans_rollback();
    echo "Batch insert failed. Rolled back changes.";
}


By using transactions, you can ensure that all the changes made during the batch insert are either saved or rolled back in case of a failure, maintaining data integrity in the database.


How to do large batch insert in Codeigniter with SQL query?

To do a large batch insert in CodeIgniter with SQL query, you can use the insert_batch() method provided by CodeIgniter's database class. Here's a step-by-step guide on how to do a large batch insert in CodeIgniter with SQL query:

  1. Create an array of data that you want to insert into the database. Each element of the array should represent a row of data to be inserted.
 1

$data = array(
    array(
        'column1' => 'value1',
        'column2' => 'value2',
        'column3' => 'value3'
    ),
    array(
        'column1' => 'value4',
        'column2' => 'value5',
        'column3' => 'value6'
    ),
    // add more rows as needed
);


  1. Load the database library in your controller or model.
1

$this->load->database();


  1. Use the insert_batch() method to insert the data into the database.
1

$this->db->insert_batch('table_name', $data);


In the above code snippet, replace 'table_name' with the actual name of the table you want to insert data into.

  1. Optionally, you can use the affected_rows() method to check how many rows were affected by the insert operation.
1

$affected_rows = $this->db->affected_rows();


That's it! You have now performed a large batch insert in CodeIgniter using the insert_batch() method. This method is optimized for inserting large amounts of data efficiently as a single query.


How to execute a large batch insert query in Codeigniter?

To execute a large batch insert query in Codeigniter, you can use the insert_batch() method of the Codeigniter's Database Query Builder class. Here's how you can do it:

  1. First, open your model file where you want to execute the batch insert query.
  2. Load the database library in your model file by using the following code: 
1

$this->load->database();


  1. Then, create an array of data that you want to insert into the database. The array should be in the format:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

$data = array(
    array(
        'column1' => 'value1',
        'column2' => 'value2',
        // add more columns and values as needed
    ),
    array(
        'column1' => 'value3',
        'column2' => 'value4',
        // add more columns and values as needed
    ),
    // add more arrays as needed
);


  1. Finally, execute the batch insert query using the insert_batch() method of the Database Query Builder class. Pass the table name and the array of data to the method like this:
1

$this->db->insert_batch('table_name', $data);


That's it! The insert_batch() method will execute a single query that inserts all the data in the array into the specified table in the database.


What is the recommended batch size for efficient large batch insert in Codeigniter?

There is no specific recommended batch size for efficient large batch insert in Codeigniter as it can vary depending on your specific application needs and the capacity of your database server. However, a common rule of thumb is to start with a batch size of around 100-1000 records and then adjust based on performance testing and monitoring.


It's important to keep in mind that larger batch sizes can lead to faster inserts but may also consume more memory and resources on your server. It's also recommended to use transactional inserts to ensure data consistency and rollback in case of errors.


Ultimately, the best batch size for efficient large batch inserts in Codeigniter will depend on your specific use case, database setup, and performance requirements. It's recommended to test different batch sizes and monitor performance metrics like execution time, memory usage, and database load to find the optimal batch size for your application.


What is the best way to test the performance of large batch insert in Codeigniter?

One way to test the performance of large batch inserts in Codeigniter is to create a test script that will simulate inserting a large amount of data into the database using Codeigniter's batch insert functionality. Here are the steps to create such a script:

  1. Create a test table in your database with the appropriate columns to store the data you want to insert.
  2. In your Codeigniter application, create a controller method that will handle the batch insert operation. This method should use Codeigniter's batch insert functionality to insert a large number of records into the test table.
  3. Create a test script that will call the controller method multiple times, each time with a different set of data to insert. You can use a loop to repeat the insert operation multiple times.
  4. Measure the time it takes for the test script to complete the batch insert operation. You can use PHP's microtime function to record the start and end times of the insert operation and calculate the total time taken.
  5. You can also monitor the SQL queries executed during the batch insert operation to check for any bottlenecks or performance issues.
  6. Repeat the test with different batch sizes and data sets to compare the performance of the batch insert operation under different conditions.


By following these steps, you can effectively test the performance of large batch inserts in Codeigniter and identify any potential optimizations or improvements that can be made to enhance the speed and efficiency of the operation.
