I'm trying to create these table:
CREATE TABLE IF NOT EXISTS `qa_discountcoupons` (
`discount_code` INT NOT NULL AUTO_INCREMENT ,
`status_code` INT NOT NULL ,
`discount_date` DATETIME NOT NULL DEFAULT 0 ,
PRIMARY KEY (`discount_code`) ,
INDEX `discounts_to_status` (`status_code` ASC) ,
CONSTRAINT `discounts_to_status`
FOREIGN KEY (`status_code` )
REFERENCES `qa_status` (`status_code` )
ON DELETE NO ACTION
ON UPDATE NO ACTION)
ENGINE = InnoDB;
But i get this error:
Error Code: 1067. Invalid default value for 'discount_date'
You can use:
CREATE TABLE IF NOT EXISTS `qa_discountcoupons` (
`discount_code` INT NOT NULL AUTO_INCREMENT ,
`status_code` INT NOT NULL ,
`discount_date` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ,
PRIMARY KEY (`discount_code`) ,
INDEX `discounts_to_status` (`status_code` ASC) ,
CONSTRAINT `discounts_to_status`
FOREIGN KEY (`status_code` )
REFERENCES `qa_status` (`status_code` )
ON DELETE NO ACTION
ON UPDATE NO ACTION)
ENGINE = InnoDB;
from MySQL 5.6.5 and up.
I suggest also checking out the thread on How do you set a default value for a MySQL Datetime column? - which has a lot of comments on this.

thanks all
I am trying to create table in Mysql database with the below sql
CREATE TABLE IF NOT EXISTS `dev_dict`.`TAMILWORD_SECONDARY` (
`ID` INT NOT NULL ,
`TAMILWORD_ID` INT NOT NULL ,
`WORDS` VARCHAR(50) NOT NULL ,
`CREATED_DTTM` TIMESTAMP NOT NULL ,

PRIMARY KEY (`ID`) ,
UNIQUE INDEX `WORDS_UNIQUE` (`WORDS` ASC, `TAMILWORD_ID` ASC) ,
INDEX `FK_TAMILWORD_ID_idx` (`TAMILWORD_ID` ASC) ,
CONSTRAINT `FK_TAMILWORD_ID`
FOREIGN KEY (`TAMILWORD_ID` )
REFERENCES `dev_dict`.`TAMILWORD` (`ID` )
ON DELETE NO ACTION
ON UPDATE NO ACTION)
ENGINE = InnoDB
but getting Error Code: 1022. Can't write; duplicate key in table 'tamilword_secondary'.
thanks for helping me.. i have the table tamilword already , and getting same error
CREATE TABLE IF NOT EXISTS `dev_dict`.`TAMILWORD` (
`ID` INT NOT NULL ,
`WORD` VARCHAR(50) CHARACTER SET 'utf8' COLLATE 'utf8_general_ci' NOT NULL ,
`SENTENCE` VARCHAR(100) NULL ,
`CREATED_DTTM` TIMESTAMP NOT NULL ,
`MODIFIED_DTTM` TIMESTAMP NOT NULL ,
PRIMARY KEY (`ID`) ,
INDEX `SECONDARY` (`WORD` ASC, `SENTENCE` ASC) )
ENGINE = InnoDB
Create dev_dict.TAMILWORD table first.
Other than that your statement works.
See SQL Fiddle example
With the following scripts, when i try to create NetBankingTransaction table, it fails with the following message:
Error Code: 1005. Can't create table 'wah_schema.netbankingtransaction' (errno: 150)

Can someone please help me understand why am I getting this error ?
This one works for me:
/*drop table if exists `Transaction`;*/
CREATE TABLE IF NOT EXISTS `Transaction`
(
`idTransaction` INT UNSIGNED NOT NULL AUTO_INCREMENT ,
`idOrder` INT UNSIGNED NOT NULL ,
`type` VARCHAR(45) NOT NULL ,

) ENGINE = InnoDB;
/*drop table if exists NetBankingTransaction;*/
CREATE TABLE IF NOT EXISTS `NetBankingTransaction`

`type` VARCHAR(45) NOT NULL DEFAULT 'NETBANKING' ,
PRIMARY KEY (`idTransaction`, `type`),

FOREIGN KEY (`idTransaction` , `type` )
REFERENCES `Transaction` (`idTransaction` , `type` )
ON DELETE CASCADE
ON UPDATE CASCADE
) ENGINE = InnoDB;
idTransaction in NetBankingTransaction table has to be unsigned. And you need an index on (idTransaction, type) in the Transaction table. Your primary key does not cover the FK requires since it's over three columns.
P.S: You don't need this in NetBankingTransaction table
INDEX fk_NetBankingTransaction_Transaction1 (idTransaction ASC, type ASC)
You need a UNIQUE KEY in Transaction (idTransaction, type) to properly add that Foreign Key constraint.
idTransaction is a different type in each table. One is unsigned and the other is signed. Try making idTransaction unsigned in the second table.
I'm modeling my db shema using MySQL Workbench CE EER modeler and now I'm stuck with mysql errno 150.
My sql code:

It fails in last statement (CREATE TABLE Orders).
I already checked:
Types of refferencing tables are equals
Indexes on all columns exists
Engine is InnoDB
Thanks for any help! Have a good day!
P.S. sorry for possible duplicate. I really can't find any problem in my code.
Some of fields are defined as NOT NULL, but you defined 'ON DELETE' action as 'SET NULL'.
Make these fields nullabe -
CREATE TABLE `myschema`.`Orders` (
`orderID` BIGINT NOT NULL AUTO_INCREMENT ,
`registerDate` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
`clientPhone` VARCHAR(15) NULL, -- NOT NULL ,
`shipmentAddress` VARCHAR(150) NOT NULL ,
`orderStatus` INT NULL, -- NOT NULL ,
`registrator` INT NULL, -- NOT NULL ,
PRIMARY KEY (`orderID`) ,
INDEX `fk_Orders_Clients` (`clientPhone` ASC) ,
INDEX `fk_Orders_OrderStatuses1` (`orderStatus` ASC) ,
INDEX `fk_Orders_WorkstationUsers1` (`registrator` ASC) ,
CONSTRAINT `fk_Orders_Clients`
FOREIGN KEY (`clientPhone` )
REFERENCES `myschema`.`Clients` (`phone` )
ON DELETE SET NULL
ON UPDATE CASCADE,
CONSTRAINT `fk_Orders_OrderStatuses1`
FOREIGN KEY (`orderStatus` )
REFERENCES `myschema`.`OrderStatuses` (`statusID` )
ON DELETE SET NULL
ON UPDATE CASCADE,
CONSTRAINT `fk_Orders_WorkstationUsers1`
FOREIGN KEY (`registrator` )
REFERENCES `myschema`.`WorkstationUsers` (`userID` )
ON DELETE SET NULL
ON UPDATE CASCADE)
ENGINE = InnoDB;
In my case, the problem was solved by adding
DEFAULT CHARACTER SET = utf8
at the end of each create table
regards!
I'm unable to see the issue with this CREATE TABLE sentences. I've double checked but can't find the error.

It's a Foreign Key issue but I'm not able to see what's wrong. Can someone help me, please?
According to this comment on MySQL manual page on Foreign keys, it may be due to different encoding of the VARCHAR columns. In table agentes you defined a collation but in relColaExt you did not.
Try using the same collation on every table (by defining it or by letting the default kick in).
