MySQL foreign key constraint fails?
On the surface, it would appear that the foreign key on post_tag_map. Tag_id column points to a table called tag as opposed to a table called tags.

Just installed MySQL 5.5 on mac os x 10.6 and am having a strange issue on many tables. Below is an example. Inserting a row fails with a foreign key constraint when it shouldn't.
The foreign key it references does exist. UPDATE: After dropping and recreating the database several times, I did a show engine innodb status after the failing insert above and got this surprising result. The parent Language table is not found!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
