converting MySQL syntax to PostgreSQL

converting MySQL syntax to PostgreSQL - mysql

So I designed a Bank database in MySQL, and now I want to convert some syntax to PostgreSQL
this is my account and branch table :
CREATE TABLE `account` (
`accountnumber` int(80) NOT NULL,
`balance` text COLLATE utf8_bin NOT NULL,
`date` date NOT NULL,
`time` time NOT NULL,
`branchID` int(25) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
CREATE TABLE `branch` (
`branchID` int(25) NOT NULL,
`bName` varchar(50) COLLATE utf8_bin NOT NULL,
`bCity` varchar(50) COLLATE utf8_bin NOT NULL,
`assests` bigint(20) NOT NULL,
`mainbankID` int(10) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
I converted it already, but I have problems with these parts:
ALTER TABLE `account`
ADD PRIMARY KEY (`accountnumber`),
ADD KEY `branchID` (`branchID`);
ALTER TABLE `account`
ADD CONSTRAINT `account_ibfk_1` FOREIGN KEY (`branchID`) REFERENCES `branch` (`branchID`);
for example, I tried to write the first one like this, and I got errors:
ALTER TABLE account
ADD PRIMARY KEY (accountnumber),
ADD KEY branchID (branchID);
and I got this error :
type "branchid" does not exist
and here's my piece of code that I converted and working in PostgreSQL :

First, you need to replace the backticks (`) with standard conforming double quotes ("). This will also prevent branchID from getting folded to lower case.
Second, instead of ALTER TABLE ... ADD KEY (colname) you have to use ALTER TABLE ... ADD UNIQUE (colname). You need a unique constraint as target of foreign key.

You can use this software for that purpose:

Why delete query only delete one record

Hi I’ve got the folowing query:
DELETE tickets, archive, files
FROM tickets
LEFT JOIN ticket_files
ON ticket_files.ticket_id = tickets.ticket_id
LEFT JOIN archive
ON archive.document_id = ticket_files.document_id
LEFT JOIN files
ON files.file_id = ticket_files.file_id
WHERE tickets.ticket_id = 21
When the ticket doesn’t have any record in the junction table ticket_files then the ticket is deleted correctly but if there is more than one record in the ticket_files then only one record is deleted from the tables archive and files. How can i make sure all the joined records are deleted also from archive and files? many thanks
This is the database structure. As you can see the ticket with ID 1 has got two files associated in the ticket_files table but ticket with ID 2 doesn't have any files associated.

You have to join each table on the primary key/foreign key. Some of the sample data is not quite correct because you have duplicate combinations of student_id and roles_id values in the roles_assigned table. Be sure to list the column names you need instead of *.
select *
from users
INNER JOIN roles_assigned ON users.id = roles_assigned.user_id
INNER JOIN roles ON roles.id = roles_assigned.role_id
INNER JOIN studentprofile on studentprofile.id = users.id
INNER JOIN schoolwithusers on schoolwithusers.studentprofile_id =
studentprofile.id
INNER JOIN schools ON schools.id = schoolwithusers.school_id
WHERE roles.type = 'Student';

foreign key and mysql with hibernate

I am using Hibernate to create table in mySql database.
I have two table "conge" and "employee" and I have a manytoone relationship. the "conge" table have a foreign key of the employee id.
I notice that after inserting exactly two row in my table "conge" I get a foreign key problem. I have used hibernate and also the phpmyadmin to insert and I have always the same problem after inserting two row.
this is my error
Cannot add or update a child row: a foreign key constraint fails (concretepage.Conge, CONSTRAINT FKk1p9i6bbic92cgaad05k4smsg FOREIGN KEY (id) REFERENCES EMPLOYE (id))
Thanks,
Update
I have exported the database this is the sql file

Because the foreign key is on column ID not employee_id ... look : FOREIGN KEY (id) REFERENCES EMPLOYE (id)) ... and you have only two rows in Employee table

#1064 SQL Syntax error

I understand this is a common and annoying problem so before I ask for an explanation I just want to say sorry.
As the title says I've been getting a 1064 syntax error from my MySQL db I imported in to php myadmin running wamp and building through netbeans.
I've checked out how other posts on the matter and have done reading about proper syntax but cannot see what my problem is.
An explanation would be greatly appreciated as I really want to learn this and improve my skills.
(if you have any questions about my code please ask)
Here's my full code:

You have a comma at the end of your INSERT INTO 'view' statement instead of a semicolon.
Should be:
INSERT INTO `view` (`view_id`, `view_profile_user`, `view_current_user`, `view_timestamp`)
VALUES (65, 'blub', 'rugsworth', '2015-10-18 19:30:56');
Does that fix it up?

You have a significant number of foreign key constraints for your table product. For example, any "size_id" you enter into table products HAS to correspond to a "size_id" in table size.
What your vb.net program is telling you is that one of the id values you are entering into table product does not exist in its corresponding table. My best guess would be that one of your id values (ie. size_id, uom_id, etc) is empty, blank, or zero.
You have a number of options - you can:
turn foreign key off for the table if you wish with SET foreign_key_checks = 0;
you can remove the foreign keys altogether
you can fix your code to ensure you are adhering to the foreign keys before you even attempt to insert a value
