I've a project at school and i must use a Derby DB.
I'm using eclipse and the SQL Scrapbook to execute my SQL script.
Here is the problem:
My SQL script was generated by Mysql Workbench, we did a schemas and then exported it to a .sql
When i try to execute it in the SQL Scrapbook, I have MANY errors, the sql seems not to be adapted to derby (for example, AUTOINCREMENT is now (START WITH 1, INCREMENT BY 1).
Here is my .sql :
SET #OLD_UNIQUE_CHECKS=##UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET #OLD_FOREIGN_KEY_CHECKS=##FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET #OLD_SQL_MODE=##SQL_MODE, SQL_MODE='TRADITIONAL';

Try using DdlUtils (http://db.apache.org/ddlutils/) to export your schema from your MySQL database, then you can import that same schema to Derby.

I am working few days with my project and I stuck on phpmyadmin sql.
I create in workbench ERR Diagram which looks like:
And the code to paste into sql query is:

SET #OLD_FOREIGN_KEY_CHECKS=##FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;

Adres means Address
Ogloszenie means Advertistment
Wojewodztwa means Province
Material means Material
Szczegoly means Details
This simple project is about advertistment which sells houses.
My error is
Executing SQL script in server
ERROR: Error 1005: Can't create table 'nieruchomosci.adres' (errno: 150)
I am total yellow in sql, where did I make mistake?
I think you reference the foreign key at the wrong position.
Instead of having the following in the definition of adres
CONSTRAINT `fk_adres_ogloszenie1`
FOREIGN KEY (`id_adres` )
REFERENCES `nieruchomosci`.`ogloszenie` (`id_adres` )
ON DELETE NO ACTION
ON UPDATE NO ACTION)
You should put this in the definition of the ogloszenie table.
Hope that helps.
I am having trouble with auto increment in SQLite using Perl.
Database design:
$dbh->do( "CREATE TABLE IF NOT EXISTS `Users` (
`UserID` VARCHAR(45) NOT NULL PRIMARY KEY UNIQUE ,
`First_Name` VARCHAR(45) NOT NULL ,
`Last_Name` VARCHAR(45) NOT NULL ,
`Email` VARCHAR(45) NOT NULL ,
`Password` VARCHAR(45) NOT NULL )" ) ;
$dbh->do( "CREATE TABLE IF NOT EXISTS `Files` (
`FileID` INTEGER AUTO_INCREMENT ,
`UserID` VARCHAR(45) NOT NULL ,
`File_Name` VARCHAR(45) NOT NULL ,
`File` BLOB NULL ,
PRIMARY KEY (`FileID`, `UserID`) ,
CONSTRAINT `fk_Files_Users1`
FOREIGN KEY (`UserID` )
REFERENCES `Users` (`UserID` )
ON DELETE CASCADE
ON UPDATE CASCADE)" ) ;
The query:
$dbh->do( "INSERT INTO Files ( UserID, File_Name )
VALUES ( '$_[0]', '$_[1]' )" ) ;
Even though I have identified the FileID as being both an AUTO_INCREMENT and a PRIMARY KEY, when I add a new field using the above query the FileID is left blank and isn't incremented automatically. Any thoughts? Have I designed the tables wrong?
Cheers,
Nate
I recommend you to create a primary key on Files table with the FileID field exclusively (you have two fields). And I think you have a typo: it's AUTOINCREMENT, (you type AUTO_INCREMENT). See this: http://www.sqlite.org/autoinc.html
I have a table called users:
CREATE TABLE `users` (
`UID` INT UNSIGNED NOT NULL AUTO_INCREMENT ,
`username` VARCHAR(45) NOT NULL ,
`password` VARCHAR(200) NOT NULL ,
`name` VARCHAR(45) NOT NULL ,
`email` VARCHAR(255) NOT NULL ,
`phone` VARCHAR(30) NOT NULL ,
`logo` VARCHAR(255) NULL ,
`address` VARCHAR(100) NULL ,
`information` TEXT NULL ,
`announcement` TEXT NULL ,
`role` INT UNSIGNED NULL ,
`yahoo` VARCHAR(100) NULL ,
`twitter` VARCHAR(20) NULL ,
`timelogin` DATETIME NULL,
PRIMARY KEY (`UID`) ,
UNIQUE INDEX `UID_UNIQUE` (`UID` ASC) ,
UNIQUE INDEX `name_UNIQUE` (`name` ASC) ,
UNIQUE INDEX `logo_UNIQUE` (`logo` ASC) ,
UNIQUE INDEX `username_UNIQUE` (`username` ASC))
ENGINE = InnoDB
DEFAULT CHARACTER SET = utf8
COLLATE = utf8_unicode_ci;
the problem is that I want to add or insert a new row like
`image_seal` VARCHAR(255) NULL ,
after logo, can we do something like that in mysql ? append-thing?
Thanks
Adam Ramadhan
ALTER TABLE users ADD COLUMN image_seal VARCHAR(255) NULL AFTER logo;
Check here for Syntax of ALTER TABLE
It seems you want to add a new column to your table, not a row.
From the MySQL reference it seems you can use the keyword AFTER.
ALTER TABLE users ADD COLUMN image_seal VARCHAR(255) AFTER logo;
should do the trick.
What are you using to administer your database? SQLBuddy, PHPmyAdmin and others can do this for you, without you needing to run queries.
What is bad in these queries for creating tables?

In SQL workbench its all ok, but using maven-sql-plugin it failed to create table candidate_history_has_candidate_changes. All names are less than 64 symbols. Please, help!
Try to narrow down the possible causes, starting with a simple create table. Try creating this simple table with and without backtick quotes in case the plugin isn't handling them properly.
Check you are logging in as the same user in both cases.
See if there are any leftovers from the tables. CREATE IF NOT EXIST does nothing if the tables already exist. (see asker's comments for more info).
Lots of possible answers here:

I have problems with creating tables & foreign key. (errno:150)
here is a screenshot Updated Image: http://img264.imagevenue.com/img.php?image=14866_db_122_223lo.jpg
Maybe the problem is the database design.

Had I paid more attention to the ERD you provided, I'd have seen that the "crows feet" were pointing upwards, when the convention is they always point down (or the left if necessary).
