RE : RE : Duplicate key delete record with same key
Victoria,
So I looked deeper in my PHP code (I wrote it in February 2002) and saw
I use a REPLACE statement:
class persistent
{
// put method to save properties into the DB
function put($thePrefix)
{
// job not done yet
$returnValue = FALSE;
// build table name and start the SQL REPLACE
statement
$sqlQuery = REPLACE INTO
.$thePrefix.get_class($this). SET ;
// build the SQL REPLACE query
foreach(get_object_vars($this) as
$property=$value)
{
$sqlQuery .= $property. ='.$value.',
;
}
// remove the , at the end of the string
$sqlQuery = substr($sqlQuery, 0,
strlen($sqlQuery)-2);
// connect to the DB, put the object and close
the DB
if( $dbLink = mysql_connect(DBHOST, DBUSER,
DBPASSWD) )
{
if( mysql_select_db(DBNAME, $dbLink) )
{
if( mysql_query($sqlQuery,
$dbLink) ) $returnValue = TRUE; // job done
}
}
mysql_close($dbLink);
return($returnValue); // boolean
}
Etc
This is PHP object code to make my member profiles (PHP objects)
persistent in the DB. I use REPLACE so the member-put() method can be
used to create or store change on member profiles.
Therefore I looked at MySQL Manual:
http://www.mysql.com/doc/en/REPLACE.html#IDX1431
REPLACE works exactly like INSERT, except that if an old record in
the table has the same value as a new record on a UNIQUE index or
PRIMARY KEY, the old record is deleted before the new record is
inserted.
So the result was predictible, sorry having sollicited the list.
JM

I tested it with 3.23.53 and it worked fine for me:
mysql update `reg_member` set id=4 where id=2;
ERROR 1062: Duplicate entry '4' for key 2
