InnoDB and My ISAM Tables
Hi All First of all i would like to know the basic difference between Inno DB and My ISAM Table types.. I wanted mySQL to support AutoIncrement , Transactions,Foreign Key Constraints,Blob, Text etc...so as per the documents i thought of using a InnoDB Table... Currently i am using 3.23.49 Max on Win 2K...I created two tables parent and child CREATE TABLE parent(id INT NOT NULL,PRIMARY KEY (id)) TYPE=INNODB; CREATE TABLE child(id INT, parent_id INT,INDEX par_ind (parent_id),FOREIGN KEY (parent_id) REFERENCES parent(id) ON DELETE CASCADE) TYPE=INNODB; After creating the tables when i executed the Query mysqlshow table status This says that the Table is of type MyISAM. This confuses me a lottt...Also the table i had created is not working for Foreign Key Relations.. What could be the soltuion...Kindly Advice -Arul - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: InnoDB and My ISAM Tables
Arul, do the equivalent of mysqladmin variables | grep 'inno' | less and check that innodb is up and running.

If you want to support InnoDB you should set up startup InnoDB option: http://www.mysql.com/doc/I/n/InnoDB_start.html and then run mysqld-max or mysqld-max-nt. You can check if you have sopport fo InnoDB using command: SHOW VARIABLES LIKE have%; If InnoDB is supported, the value of variable have_innodb must be 'YES'.
