I found this code which seems to work but I need to make sure it does not add duplicate records and that it updates existing records with like key values.

Will the code below Insert only or will it Replace the records with same primary key.
If not whats the mysql statement to Replace when doing a LOAD DATA INLINE??


========== IMPORT RECORDS INTO MYSQL FROM CSV FILE  ===================



    $csvfile1 = 'property_a.csv';
   
    $sql = mysql_query("LOAD DATA LOCAL INFILE '$csvfile1' INTO TABLE table_a FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' LINES
TERMINATED BY '\n' IGNORE 1 LINES") or die (mysql_error());
    if (!$sql) {        // problem
        echo mysql_error() ."<br>";
    } else {
        echo "success!";

        }

just apply REPLACE:
http://dev.mysql.com/doc/refman/5.1/en/load-data.html
he REPLACE and IGNORE keywords control handling of input rows that duplicate existing rows on unique key values:

    If you specify REPLACE, input rows replace existing rows. In other words, rows that have the same value for a primary key or unique index as an existing row. See Section 13.2.7, “REPLACE Syntax”.
