Inserting data from sql query into Mysql table using PDO

I'm extracting some data from different tables in an oracle database into an array.
I'm trying to insert the fields into a mysql table using PDO connection.

this is the query I make:
$query = "SELECT field1, field2, field3 FROM table1;

$ORACLE_STATIC = OCIParse($ORACLE_CONNECT, $query);
OCIExecute($ORACLE_STATIC, OCI_DEFAULT);

Open in new window


what is the correct way of inserting all the rows from the query using PDO?
I have about 20 fields and 500k rows.

The best answer here would depend on how often you intend to do this and what the timeliness requirements might be.  If it's a one-time process, there is not much point in optimizing.  Just run the Oracle query and as your script iterates over the results set, run a single MySQL INSERT query.  You may have to restart the process a few times to get 500K rows moved over, depending on the amount of time that your PHP script is allowed to run.
