Ferindo Paul, I discovered that this foreign key constraint wasn't present in these tables anymore due to my own action. You see, I had backed up my database before using MySQL Administrator, not knowing that is was backing up such tables constructs as foreign keys, etc. So the database I'm looking at today isn't the same database I originally created with the same constraints... I'm going to stop using MySQL Administrator... using it seems somewhat misleading and it made me think that the tables sand the constraints I made on them were still present. Thanks.

You might consider another approach: Load the data into a temporary table, delete from it those records that have no product_id match (use the multiple-table DELETE syntax that enables you to delete records based on join conditions), and then load the remaining records into your target table (INSERT ...

Re: help with character sets and collation
Thank you Gleb, I'm afraid I'm in over my head on this subject as I am restricted to make db changes via sql or phpmyadmin.It seem from your references the database character_set needs to be set to latin? I'm speculating to change character_sets and collations I need access to other utilites, programs or server administrative functions I am not aware of. I have inspected other servers I work on which enable me to insert accented characters and it appears they all have the following settings: character_set: latin1 character_sets latin1 big5 czech euc_kr gb2312 gbk latin1_de sjis...

Re: help with character sets and collation
Hello. Chris, the collation is subordinated to the character set. You should work with the character sets, and only after with collations. The data which you store in your table is silently converted to ascii character set. Are you sure that the characters which you want to store are present in ascii character set? You should change the character set of the fields of your table to that one which can hold non English characters. Another question - are you sure that the data which you're passing to MySQL is in latin1 encoding? See: http://dev.mysql.com/doc/refman/5.0/en/charset-connection.html http://dev.mysql.com/doc/refman/5.0/en/charset-general.html How to change the character set of the fields is described at: http://dev.mysql.com/doc/refman/5.0/en/alter-table.html Chris wrote: > I'm sorry but I do not know what you mean by NO_TABLE_OPTIONS in > @@sql_mode). > > The database has a Collation = ascii_general_ci.
