I have following table structers:

CREATE TABLE IF NOT EXISTS `campaignmaster` (
`id` INT(11) NOT NULL AUTO_INCREMENT ,
`propertyId` INT(11) NOT NULL ,
`name` VARCHAR(100) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`campaignCode` VARCHAR(20) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`propertyName` VARCHAR(100) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`desc` VARCHAR(100) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`status` ENUM('Pending','Approved','InProcess','NotApproved','Suspended','Expired') CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`comments` VARCHAR(255) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`impactsForecast` ENUM('Y','N') CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT 'N' ,
PRIMARY KEY (`id`) )
ENGINE = MyISAM
DEFAULT CHARACTER SET = utf8
COLLATE = utf8_unicode_ci;

CREATE UNIQUE INDEX `ui_campaignmaster` ON `campaignmaster` (`propertyId` ASC, `campaignCode` ASC, `name` ASC) ;
Another child table
CREATE TABLE IF NOT EXISTS `campaigndetails` (
`campaignDetailsID` INT(11) NOT NULL AUTO_INCREMENT ,
`id` INT(11) NOT NULL DEFAULT '0' ,
`offerCode` VARCHAR(20) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NOT NULL DEFAULT '' ,
`offerType` ENUM('Discount','Casino','Rate','Other') CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`campaignStartDate` DATE NOT NULL ,
`campaignEndDate` DATE NOT NULL ,
`occStartDate` DATE NOT NULL ,
`occEndDate` DATE NOT NULL ,
`minLOS` INT(11) NULL DEFAULT NULL ,
`maxLOS` INT(11) NULL DEFAULT NULL ,
`minAdvPurchase` INT(11) NULL DEFAULT NULL ,
`DOW` CHAR(25) CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci' NULL DEFAULT NULL ,
`numberofContacts` INT(11) NULL DEFAULT NULL ,
`expectedResponses` INT(11) NULL DEFAULT NULL ,
`actualResponses` INT(11) NULL DEFAULT NULL ,
PRIMARY KEY (`campaignDetailsID`, `id`) ,
CONSTRAINT `fk_campaigndetails_campaignmaster`
FOREIGN KEY (`id` )
REFERENCES `campaignmaster` (`id` )
ON DELETE NO ACTION
ON UPDATE NO ACTION)
ENGINE = MyISAM
DEFAULT CHARACTER SET = utf8
COLLATE = utf8_unicode_ci;

CREATE UNIQUE INDEX `ui_campaigndetails` ON `campaigndetails` (`id` ASC, `offerCode` ASC, `campaignStartDate` ASC, `campaignEndDate` ASC, `occStartDate` ASC, `occEndDate` ASC) ;

CREATE INDEX `fk_campaigndetails_campaignmaster` ON `campaigndetails` (`id` ASC) ;
How to define .HBM for above two tables
In table 1
CREATE UNIQUE INDEX `ui_campaignmaster` ON `campaignmaster` (`propertyId` ASC, `campaignCode` ASC, `name` ASC) ;

Table 2:
CREATE UNIQUE INDEX `ui_campaigndetails` ON `campaigndetails` (`id` ASC, `offerCode` ASC, `campaignStartDate` ASC, `campaignEndDate` ASC, `occStartDate` ASC, `occEndDate` ASC) ;

CREATE INDEX `fk_campaigndetails_campaignmaster` ON `campaigndetails` (`id` ASC) ;

can you explain what is your problem
