You can use below statement.

I'm trying to create a table so that I can pass in a csv file to load it into the table but I'm getting this error and I'm not sure why. Here's what I have:
CREATE TABLE imdb(
-> rank int auto_increment PRIMARY key,
-> title varchar(255),
-> genre varchar(255),
-> director varchar(255),
-> actors varchar(255),
-> year int,
-> rating decimal(1,1),
-> votes int,
-> metascore int
-> );
Here is the error:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'rank int
auto_increment PRIMARY key,
title varchar(255),
genre varchar(255),
dir' at line 2
Those arrows shouldn't be there (maybe something that got added when copy/pasting?). Also, rank and year are reserved words (thanks #
Aloiso Gomes) so you have to add backticks to allow the name anytime you reference it (stored procs, selects, inserts, etc.)
This works:
CREATE TABLE imdb(
`rank` int auto_increment PRIMARY key,
`title` varchar(255),
`genre` varchar(255),
`director` varchar(255),
`actors` varchar(255),
`year` int,
`rating` decimal(1,1),
`votes` int,
`metascore` int
);
INSERT INTO imdb (title,genre) VALUES
('Fast Furious 1', 'racing'),
('Fast Furious 2', 'racing'),
('Fast Furious 3', 'racing?'),
('Fast Furious 4', '"racing"');
SELECT `rank`, title, genre FROM imdb;
I want to insert two values(composite keys) only when those don't already exist otherwise Mysql will give error about duplicate keys getting entered.
My this query is giving error:
INSERT INTO group_msg_response (license_id,grp_id) VALUES (1,1) WHERE NOT EXISTS (SELECT 1 FROM group_msg_response WHERE license_id=1 AND grp_id=1 )
If I run them individually they both run fine.
It is giving this error:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE NOT EXISTS (SELECT 1 FROM group_msg_response WHERE license_id=1 AND ' at line 1
What could be the problem? I'm doing the way as mentioned in https://dev.mysql.com/doc/refman/5.5/en/exists-and-not-exists-subqueries.html
Here is the table definition:
create table IF NOT EXISTS msg(
id INT UNSIGNED AUTO_INCREMENT ,
en varchar(5000),
hi varchar(5000),
PRIMARY KEY(id)
) ENGINE=InnoDB;
create table IF NOT EXISTS group_msg(
id INT UNSIGNED AUTO_INCREMENT ,
msg_id INT UNSIGNED,
lsource INT UNSIGNED NOT NULL,
browser CHAR(1) NOT NULL DEFAULT 'a' ,
expiry_date DATETIME NOT NULL ,
dated DATETIME NOT NULL,
deleteit TINYINT DEFAULT 0 ,
FOREIGN KEY (msg_id)
REFERENCES msg(id)
ON DELETE CASCADE
ON UPDATE CASCADE,
PRIMARY KEY(id)
) ENGINE=InnoDB;
create table IF NOT EXISTS group_msg_response(
license_id MEDIUMINT,
grp_id INT UNSIGNED,
FOREIGN KEY (grp_id)
REFERENCES group_msg(id)
ON DELETE CASCADE
ON UPDATE CASCADE,
PRIMARY KEY(license_id,grp_id)
) ENGINE=InnoDB;
Use select, not values:
INSERT INTO group_msg_response (license_id, grp_id)
SELECT license_id, grp_id
FROM (SELECT 1 as license_id, 1 as grp_id) x
WHERE NOT EXISTS (SELECT 1
FROM group_msg_response gmr
WHERE gmr.license_id = x.license_id AND
gmr.grp_id = x.grp_id
);
Or, better yet, let the database do the work by creating a unique index/constraint:
create unique index unq_gmr_license_grp on group_msg_response(license_id, grp_id) ;
Then you can do the insert as:
INSERT INTO group_msg_response (license_id, grp_id)
VALUES (1, 1)
ON DUPLICATE KEY UPDATE license_id = VALUE(license_id);
The ON DUPLICATE KEY clause does nothing -- except prevent an error from occurring.
I recently bought this book called "SQL Queries for Mere Mortals (3rd Edition" to study SQL. It came with MySQL scripts that they said I could run and have example databases to work with and follow along with the book. However, some of the scripts are resulting in an error message. Here is one example script that will not work:

I have tried running other scripts that came with the book that also starts with "CREATE DATABASE" and some of them ran smoothly without any errors, so I'm confused as to why I'm getting this error message. Any help would be greatly appreciated! Thanks all!
Note that since this script has a "CREATE DATABASE" at the top it will fail if that database already exists. That also means that if it works partially and you run it again, it;ll fail completely the next time. "CREATE DATABASE" is a pretty big hammer, so you probably don't want to get into the habit of doing it a lot. But, having said that, here's an even bigger hammer; add
DROP DATABASE IF EXISTS EntertainmentAgencyModify;
in front of the CREATE and similarly for the others. When you have real data, you, of course, never want to use either of these.
Can you try running the following just by typing it in your mysql console:
CREATE DATABASE EntertainmentAgencyModify;
It should simply work, or at least tell you something more then a syntax error.
The code executes fine. May be its a problem with your MySql.
Try to install a new MySql. :)

Thanks everyone! I have no idea why this works, but I found a solution. I had to simply delete "CREATE " from the first line of the script and re-type it. Then it worked. If anyone has any idea why this seemingly irrelevant solution worked, I'd love to know. Thanks everyone for your help!
Alright so I'm trying to tie a Spigot plugin that I'm making into MySQL, and I did it successfully up until the point where I edited the code that was creating the table. I find that MySQL stack traces are much too ambiguous to be useful, so I have no idea what I'm doing wrong here.
Code:
CREATE TABLE IF NOT EXISTS WebsiteLink_keys(id INT NOT NULL KEY AUTO_INCREMENT, key VARCHAR(36), trimmedUUID VARCHAR(36), playerUUID VARCHAR(36), date TIMESTAMP, status TEXT);
key is a reserved word in MySQL. If you absolutely must use it as a column name, you can escape it using backticks:
CREATE TABLE IF NOT EXISTS WebsiteLink_keys (
id INT NOT NULL KEY AUTO_INCREMENT,
`key` VARCHAR(36), -- Here!
trimmedUUID VARCHAR(36),
playerUUID VARCHAR(36),
date TIMESTAMP,
status TEXT
)
Or, better yet, use a name that isn't a reserved word, such as link_key:
CREATE TABLE IF NOT EXISTS WebsiteLink_keys (
id INT NOT NULL KEY AUTO_INCREMENT,
link_key VARCHAR(36), -- Here!
trimmedUUID VARCHAR(36),
playerUUID VARCHAR(36),
date TIMESTAMP,
status TEXT
)
CREATE TABLE IF NOT EXISTS WebsiteLink_keys(
id INT NOT NULL AUTO_INCREMENT,
`key` VARCHAR(36),
trimmedUUID VARCHAR(36),
playerUUID VARCHAR(36),
`date` TIMESTAMP,
status TEXT,
PRIMARY KEY (id)
);
PRIMARY KEY (id) is at the end
CREATE TABLE person_details
( id NOT NULL AUTO_INCREMENT,
name varchar(100),
age int,
gender varchar(8),
adult varchar(10),
contact_no int,
address varchar(255),
pnr_number int
)
Error at Command Line:2 Column:15
Error report:
SQL Error: ORA-00907: missing right parenthesis
00907. 00000 - "missing right parenthesis"
*Cause:
*Action:
You forgot to define the type of id field here:
( id NOT NULL AUTO_INCREMENT,
Should be something like:
( id INT NOT NULL AUTO_INCREMENT,
^^^^
And make it as a primary key like
pnr_number int,
PRIMARY KEY (id)
