db query builder - maximusto - 09-01-2019
I have a need to load multiple records into a database.
There is a chance that some of these records might be duplicates (existing primary key).
I want this to be fast and secure (no sql injection etc).
Performing a loop and error checking $this->db->insert('mytable', $data); is not performant.
Performing $this->db->insert_batch('mytable', $data); will fail. When I perform a $this->db->error() catch then I capture the first statement that failed in the $data. No clean way to resolve the issue (duplication) and resolve.
Effectively I want 'Insert' statements generated by the query builder to be 'Insert Ignore'.
Options
* I would like to extend the Database component (without hacking / properly)
* Am I missing a $this->db->ignore feature?
* ???
As a hack, I have added to database\DB_query_builder.php with copied functions of public function insert_batch and _insert_batch to create insert_ignore_batch and _insert_ignore_batch where the "return 'INSERT INTO'" has been changed to "return 'INSERT IGNORE INTO'"
Any advise on the best way to approach?
Thanks
Paul

How many times haven't I been wishing for a way to extend the database classes...
