I am trying to migrate my osclass installation to another server. I have copied all files and created a new database. When trying to import my database from backup, I get "#1215 - Cannot add foreign key constraint".
It shows that this bit is a problem:

Please help.
You must create first the tables you want to reference, for example, here is one foreing key that reference one table, also the type of the key must match, follow this example an add the rest of your tables, I will show a minimum example that works in the creation of the tables, you must add the correct data of course:

What I want to do is:
To select DISTINCT industry from Company table
To insert into Industry table first and get auto incremented ID
With this ID to insert again into IndustryTranslation table and set "language"="en"
To insert Company's id and newly generated Industry's id into MapCompanyIndustry table
I know that it's not possible with one statement. But definitely it's possible with transaction. Can't figure out how to achieve this result with one transaction.
Any suggestions?

I have two tables in MySql Database:
Captain(captain.email)
Members(member.email)
I want when captain table insert data in captain.email then check If members table data in members.email are already exit then data in captain.email not insert in captain table.
How it is possible ?
1.Captain :
CREATE TABLE `captain` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) NOT NULL,
`username_canonical` varchar(255) NOT NULL,
`email` varchar(255) NOT NULL,

UNIQUE KEY `UNIQ_957A647992FC23A8` (`username_canonical`),
UNIQUE KEY `UNIQ_957A6479A0D96FBF` (`email_canonical`)
)
2.Members :
CREATE TABLE `members` (

`fos_user_id` int(11) DEFAULT NULL,
`name` varchar(45) DEFAULT NULL,

)
There is no way to enforce such constraint.
Using declarative referential integrity (DRI) you could create a table that contains all of the columns that you need to build a unique key on.
I have the following dump:
CREATE TABLE `testdata`.`carer` (
`ID` bigint(20) NOT NULL auto_increment,
`IS_DELETED` bit(1) default NULL,
`name` varchar(255) default NULL,
`account_id` bigint(20) NOT NULL,
`patient_carer_id` bigint(20) NOT NULL,
PRIMARY KEY (`ID`),
KEY `FK5A0E781D4C45C51` (`patient_carer_id`),
KEY `FK5A0E7818BCEF0FB` (`account_id`),
CONSTRAINT `FK5A0E781D4C45C51` FOREIGN KEY (`patient_carer_id`) REFERENCES `patients` (`ID`),
CONSTRAINT `FK5A0E7818BCEF0FB` FOREIGN KEY (`account_ID`) REFERENCES `account` (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=55 DEFAULT CHARSET=utf8
but as result i see the following:
ERROR 1061 (42000): Duplicate key name 'FK5A0E7818BCEF0FB'
Yep, key's name and constrain's name are same. But with other key we haven't any problems.
But if I'll change KEY FK5A0E7818BCEF0FB to FK5A0E7818BCEF0FB1 , it will be working.

You're hitting mysql bugs 39932 and 45307.
Instead of
CONSTRAINT `FK5A0E7818BCEF0FB` FOREIGN KEY (`account_ID`) REFERENCES `account` (`ID`)
try
CONSTRAINT `FK5A0E7818BCEF0FB` FOREIGN KEY (`account_id`) REFERENCES `account` (`ID`)
Note the change of case of account_id.
