MySQL: Creating table with FK error (errno 150)
- by Peter Bailey
I've tried searching on this error and nothing I've found helps me, so I apologize in advance if this is a duplicate and I'm just too dumb to find it.
I've created a model with MySQL Workbench and am now attempting to install it to a mysql server.
Using File Export Forward Engineer SQL CREATE Script... it outputs a nice big file for me, with all the settings I ask for. I switch over to MySQL GUI Tools (the Query Browser specifically) and load up this script (note that I'm going form one official MySQL tool to another). However, when I try to actually execute this file, I get the same error over and over
SQLSTATE[HY000]: General error: 1005
Can't create table
'./srs_dev/location.frm' (errno: 150)
"OK", I say to myself, something is wrong with the location table. So I check out the definition in the output file.

Looks ok to me. I surmise that maybe something is wrong with the Query Browser, so I put this file on the server and try to load it this way
] mysql -u admin -p -D dbname < path/to/create_file.sql
And I get the same error. So I start to Google this issue and find all kinds of accounts that talk about an error with InnoDB style tables that fail with foreign keys, and the fix is to add "SET FOREIGN_KEY_CHECKS=0;" to the SQL script. Well, as you can see, that's already part of the file that MySQL Workbench spat out.
So, my question is then, why is this not working when I'm doing what I think I'm supposed to be doing?
