ERROR 1005 (HY000): Can't create table 'thunderhawk.members' (errno: 150)

Any ideas?

I know it is a foreign key problem. I seem to be following the foreign key syntax...

This question is a dupe of:

MySQL: Can't create table (errno: 150)

The error message tells you exactly what the problem is: table thunderhawk.members cannot be created because of error number (errno) 150, a foreign key constraint would be violated:

FOREIGN KEY (PROVIDER_ID) REFERENCES PROVIDER(PROVIDER_ID)

You cannot create the members table before creating the provider table, because the members table has a foreign key dependency on the provider table.

Usually, If the dbms is not able to create a table that means the following things could have gone wrong: a) The dbms process doesnt has write permission to write in the data directory, or the disk quota for the folder has exceeded. b) file system is full and there is no space to write any data to the file.

Check your mysqld.log for more details.

first thing you need to sure that check that both table need to have same storage type like InnoDB.

Try this code:

DROP TABLE IF EXISTS members;

CREATE TABLE members (
    Member_ID char(10) NOT NULL default 0,
    Provider_ID char(10) NOT NULL default 0,
    First_Name varchar(30) NOT NULL default 0,
    Middle_Initial char(1) NOT NULL default 0,
    Last_Name varchar(40) NOT NULL default 0,
    Address varchar(100) NOT NULL default 0,
    City varchar(100) NOT NULL default 0,
    State char(2) NOT NULL default 0,
    Zip varchar(5) NOT NULL default 0,
    PRIMARY KEY  (Member_ID),
     FOREIGN KEY (PROVIDER_ID) REFERENCES PROVIDER(PROVIDER_ID)
) ;
