You should remove all " characters like below:
CREATE TABLE categories (
id int(11) NOT NULL,
name varchar (255) NOT NULL
) ENGINE = INNODB DEFAULT CHARSET = lantin1;
CREATE TABLE stages
( id int (11) NOT NULL,
categorie_id int(11) NOT NULL,
entreprise varchar(255) NOT NULL,
nome varchar(255) NOT NULL,
description varchar(255) NOT NULL,
location varchar(255) NOT NULL,
contact varchar(255) NOT NULL,
contact_email varchar(255) NOT NULL
) ENGINE = INNODB DEFAULT CHARSET = latin1;
ALTER TABLE categories
ADD PRIMARY KEY (id);
ALTER TABLE stages
ADD PRIMARY KEY (id);
ALTER TABLE categories
MODIFY id int(11) NOT NULL AUTO_INCREMENT;
ALTER TABLE stages
MODIFY id int(11) NOT NULL AUTO_INCREMENT;

This is my code:
CREATE TABLE supplier -- creating table supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO
I get the the error:
Msg 2714, Level 16, State 6, Line 34
There is already an object named 'supplier' in the database.
Any help? Thanks!
Please try this code.
IF EXISTS(SELECT 1 FROM sys.tables WHERE name = 'supplier')
DROP TABLE dbo.supplier;
CREATE TABLE dbo.supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO
You need to check if the table exists first
IF OBJECT_ID('dbo.supplier', 'U') IS NOT NULL
DROP TABLE dbo.supplier;
CREATE TABLE dbo.supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO
If you are using 2016+ you can use
DROP TABLE IF EXISTS dbo.supplier;
CREATE TABLE dbo.supplier
(
supplierID INT NOT NULL IDENTITY,
supplierName VARCHAR(30) NOT NULL,
suppplierNo VARCHAR(10) NOT NULL,
supplierEmail VARCHAR(30) NOT NULL,
CONSTRAINT PK_supplierID PRIMARY KEY(supplierID)
)
GO
I know the error 150 is related to foreign keys, but i can't figure out what wrong here.
CREATE TABLE IF NOT EXISTS User(

The error occurs when i try to create tables Livre and Publication.
Types are the same so it doesn't seem to be the problem.
By mindful of the order in which you create the tables.
For instance, your table creation statement for Livre defines a foreign key on Editeur. But the table Editeur has not been created yet.
Adjust the create table statement ordering as required.

Keep getting error Cannot add or update a child row: a foreign key constraint fails
If someone could be that would be great:)
Your keys in the membersid table (please change that name to members) are messed up. Try
CREATE TABLE IF NOT EXISTS members

`clubId` int(11) NOT NULL,

How do I delete all laptops made by a manufacturer that doesn’t make PCs?
I currently have the following tables:
CREATE TABLE `Device` (
`model` varchar(50) NOT NULL DEFAULT '',
`speed` double DEFAULT NULL,
`RAM` int(11) DEFAULT NULL,
`HD` int(11) DEFAULT NULL,
`list_price` double DEFAULT NULL,
`type` varchar(45) NOT NULL,
`screen` varchar(45) DEFAULT NULL,
PRIMARY KEY (`model`,`type`)
);
INSERT INTO `Device` VALUES
('GATE TOP',2.5,2000,500,1000,'LAPTOP','12'),
('GATE TOWER',2.5,2000,500,1000,'DESKTOP',NULL),
('HELLO TOWER',3.5,8000,1000,1299,'DESKTOP',NULL),
('MACBOOK AIR',2.5,2048,500,599,'LAPTOP','11'),
('MACBOOK PRO',3.5,8000,1000,1299,'LAPTOP','19'),
('PAAP',2.5,2048,500,599,'DESKTOP',NULL),
('TOWER',3,3100,400,2499,'DESKTOP',NULL),
('ULTRA TOWER',6,5000,1000,8999,'DESKTOP',NULL),
('VAIO',2.5,2000,500,569,'LAPTOP','12'),
('VAIO TOWER',2.5,2000,500,569,'DESKTOP',NULL);
CREATE TABLE `Product` (
`manu_Name` varchar(50) NOT NULL DEFAULT '',
`model` varchar(50) NOT NULL DEFAULT '',
PRIMARY KEY (`manu_Name`,`model`),
KEY `Product` (`model`),
CONSTRAINT `Product_ibfk_1` FOREIGN KEY (`manu_Name`)
REFERENCES `Manufacturer` (`name`),
CONSTRAINT `Product_ibfk_2` FOREIGN KEY (`model`)
REFERENCES `Device` (`model`)
);
INSERT INTO `Product` VALUES
('GATEWAY','GATE TOP'),('GATEWAY','GATE TOWER'),
('ACER','HELLO TOWER'),('APPLE','MACBOOK AIR'),
('APPLE','MACBOOK PRO'),('ACER','PAAP'),
('DELL','TOWER'),('SONY','VAIO'),
('SONY','VAIO TOWER');
CREATE TABLE `Manufacturer` (
`name` varchar(50) NOT NULL,
`country` varchar(50) DEFAULT NULL,
`phone` varchar(10) DEFAULT NULL,
PRIMARY KEY (`name`)
);
INSERT INTO `Manufacturer` VALUES
('ACER','TAIWAN','9024801111'),
('APPLE','UNITED STATES','9028189125'),
('DELL','UNITED STATES','9025551234'),
('GATEWAY','UNITED STATES','8705551698'),
('SONY','JAPAN','0123456789'),
('TOSHIBA','JAPAN','1235553560');
The delete statement would be something like this:
delete from `Device` where `model` in (
select `model` from `Product` where `manu_Name` in ('APPLE')
);
CREATE TABLE `batchinfo` (
`rowid` int(11) NOT NULL AUTO_INCREMENT,

I want to start the auto incremenet from 20000.
How do I do that? Can I edit the table some how to start incrementing from 20000?
ALTER TABLE batchinfo AUTO_INCREMENT = 20000;
See also Autoincrement
See the last line of your query:
AUTO_INCREMENT=15034
Change it to:
AUTO_INCREMENT=20000
Easy as that! :)
CREATE TABLE `batchinfo` (
`rowid` int(11) NOT NULL AUTO_INCREMENT,
`datapath` mediumtext,
`analysistime` varchar(50) DEFAULT NULL,
`reporttime` varchar(50) DEFAULT NULL,
`lastcalib` varchar(50) DEFAULT NULL,
`analystname` varchar(150) DEFAULT NULL,
`reportname` varchar(150) DEFAULT NULL,
`batchstate` varchar(150) DEFAULT NULL,
`instrument` varchar(20) DEFAULT NULL,
PRIMARY KEY (`rowid`),
UNIQUE KEY `rowid_UNIQUE` (`rowid`)
) ENGINE=InnoDB AUTO_INCREMENT=20000 DEFAULT CHARSET=latin1;
INSERT INTO batchinfo (datapath) values('test');
SELECT * FROM batchinfo;
I don't know how to do it from the CREATE statement, but after that you can do this:
ALTER TABLE `batchinfo` AUTO_INCREMENT = 20000;
