All tables must be InnoDb. –Devart Jun 15 '12 at 6:01 @Devart: Thanks, I found my mistake... it is because the receiptno in sales table is not a primary key... I should reference it to a new column with primary key, for example, sales_no –Boon Jun 15 '12 at 9:37 add a comment| 4 Answers 4 active oldest votes up vote 22 down vote accepted Check out the MySQL manual about foreign key constrains: If you re-create a table that was dropped, it must have a definition that conforms to the foreign key constraints referencing it. It must have the right column names and types, and it must have indexes on the referenced keys, as stated earlier. If these are not satisfied, MySQL returns error number 1005 and refers to error 150 in the error message. A few ideas: Better drop the tables and create it new with a well formed syntax. Make sure to add ENGINE=InnoDB; to your CREATE TABLE - command. Make sure InnoDB is enabled on your MySQL server. To verify this, try this command: SHOW VARIABLES LIKE 'have_innodb'; - if it returns a YES, then InnoDB is enabled. Check your command for upper- and lowercases in table- and fieldnames. Check this not only one the table you want to create, but also on th

ERROR 1005 (HY000): Can't create table './mndb/#sql-992_406.frm' (errno: 150) How to repeat: create table foo(id integer) ; create table bar(id integer) ; alter table foo add foreign key(id) references bar(id) ; returns: error 1005 ERROR 1005 (HY000): Can't create table './mndb/#sql-992_406.frm' (errno: 150) It appears that MySQL is generating a temporary table with '#' in it. I see that in general, there is a bug that innodb can not deal with # in table names. I would argue that that is a different bug since it was talking about tables that the user generates. I have no control over these temporary tables, error 1005 hy000 and therefore no work-around at all. Suggested fix: Make it work. :) Or at least change the temporary table to not use #.

It has to do with trying to successfully set foreign keys in MySQL. ERROR 1005: Can't create table (errno: 150) Great, that's fantastic. Here's an example of where this error will occur. CREATE TABLE main(
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
PRIMARY KEY(id)
);
CREATE TABLE other(
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
main_id INT NOT NULL,
PRIMARY KEY(id),
FOREIGN KEY(main_id) REFERENCES main(id)
); So I'm trying to make the table "other" reference the table "main" through the foreign key "main_id" and, if you try it, it'll throw an Error 150. Want the solution? The foreign key "main_id" has to have the exact same type as the primary key that it references. In the example, "main_id" in the table "other" has the type INT NOT NULL while "id" in the table "main" has the type "INT UNSIGNED NOT NULL" and also AUTO_INCREMENT, but that isn't something we have to worry about. To make things incredibly clear, here's the working example. CREATE TABLE main( id INT UNSIGNED NOT NULL AUTO_INCREMENT, PRIMARY KEY(id) ); CREATE TABLE other( id INT UNSIGNED NOT NULL AUTO_INCREMENT, main_id INT UNSIGNED NOT NULL, PRIMARY KEY(id), FOREIGN KEY(main_id) REFERENCES main(id) ); To solve ‘MySQL ERROR 1005: Can't create table (errno: 150)‘ you likely just have to ensure that your foreign key has the exact same type as the primary key.
