Syntax error due to using a reserved word as a table or column name in MySQL
(1 answer)
When to use single quotes, double quotes, and backticks in MySQL
(13 answers)
Closed last year.
I am trying to create a table in MySQL, but I am getting an error. The code is looking OK to me, but I don't know why I am getting the error.
This is the code :
CREATE TABLE usage (
user_id VARCHAR(20) ,
usage_date DATE ,
usage_location VARCHAR(20) ,
time_spent INT
);
The error that I am getting:
Query 1: 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 'usage (
user_id VARCHAR(20) ,
usage_date DATE ,
usage_locatio' at line 1
try using some other names like usage1 for datausage because that is reserved
CREATE TABLE stuffusage (
user_id VARCHAR(20) ,
usage_date DATE ,
usage_location VARCHAR(20) ,
time_spent INT
);
Try putting backticks around usage. It seems to be a keyword.
CREATE TABLE `usage` (
user_id VARCHAR(20) ,
usage_date DATE ,
usage_location VARCHAR(20) ,
time_spent INT
);
"usage" cannot be used as a table name. It is a special code defined in MYSQL.

Good Day!
what is the proper syntax query in MySQL? I'm getting error in mysql during execution (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 'EmpCode AS CONCAT('EMP' , RIGHT(Concat('0000', CONVERT(EmpId, ' at line 3)
CREATE TABLE tbEmployee
(
EmpId INT NOT NULL, PRIMARY KEY,
EmpCode AS CONCAT('EMP' , RIGHT(Concat('0000', CONVERT(EmpId, CHAR(5))),5)) PERSISTED,
EmployeeName VARCHAR(50),
Age INT,
Gender VARCHAR(10)
)
MySQL generated columns are either VIRTUAL (the default) or STORED, the latter corresponding to SQL Server's persisted. Try this version:
CREATE TABLE tbEmployee (
EmpId INT NOT NULL PRIMARY KEY,
EmpCode VARCHAR(50) AS (CONCAT('EMP', LPAD(EmpId, 5, '0'))) STORED,
EmployeeName VARCHAR(50),
Age INT,
Gender VARCHAR(10)
);
Note also that MySQL is a bit more lax with regards to casting numeric columns to text. Also, we can use MySQL's LPAD function to left pad the employee ID with zeroes, to a width of 5 digits.
I tried to create a brand new table with codes:
MySQL [distributor]> create table order
-> (
-> order_num integer not null,
-> order_date datetime not null,
-> cust_id chat(10) not null
-> );
It generates errors:
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 'order
(
order_num integer not null,
order_date datetime not null,
cust_id chat(' at line 1
I have checked multiple times to ensure there no problems in my codes since SQL is case-insensitive.
What's the bug with my code?
There are two issues with your query: Firstly, order is a MySQL reserved word. Secondly, you have chat which should be char. Try this instead (renaming table to orders):
CREATE TABLE orders
(
order_num integer not null,
order_date datetime not null,
cust_id char(10)
);
order it's a reserved word and put char instead of chat. You can name the table orders

I am pulling my hair out over this. I have connected to a MySQL server and am trying to create a table on it:
CREATE TABLE order (
order_id INT,
order_is_overnight BIT,
order_quantity INT,
order_amount DOUBLE,
order_timestamp DATETIME
);
When I run this I get:
Error: 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 'order (
order_id INT,
order_is_overnight BIT,
order_quantity INT,
order_amou' at line 1
SQLState: 42000
ErrorCode: 1064
This is the world's vaguest error message, akin to a Java exception that says "Whoops, something went wrong somewhere in your code!"
Any ideas where I'm going awry?! I have checked, and rechecked, and rechecked and this seems to be a perfectly valid/legal CREATE TABLE statement (don't worry about performance, indexes, keys, etc.; this is just a dummy/test table).
order is an reserved word, you must enclose it name in back quotes
CREATE TABLE `order` (
order_id INT,
order_is_overnight BIT,
order_quantity INT,
order_amount DOUBLE,
order_timestamp DATETIME
);
I am having the following error when trying to execute the following code in phpMyAdmin. I am using WAMP Server with MySQL version 5.5.8 ::
The error is:
#1064 - 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 'NUMERIC(6) not null, payee VARCHAR2(20) not null, amount DECIMAL(6,2) no' at line 3
the SQL is:
CREATE TABLE checks
(
check NUMERIC(6) not null,
payee VARCHAR2(20) not null,
amount DECIMAL(6,2) not null,
remarks VARCHAR2(20) not null
)
EDIT
I am also trying to execute this but it gives also error:
CREATE TABLE deposits
(
deposit NUMBER(8),
whopaid VARCHAR(25),
amount DECIMAL(6,2),
remarks VARCHAR(20)
)
You need to escape check with backticks since it is a reserved word. And in MySQL there is no varchar2 data type, just varchar.
CREATE TABLE checks
(
`check` NUMERIC(6) not null,
payee VARCHAR(20) not null,
amount DECIMAL(6,2) not null,
remarks VARCHAR(20) not null
)
Also replace NUMBER with NUMERIC in your 2nd create statement.
CREATE TABLE deposits
(
deposit NUMERIC(8),
whopaid VARCHAR(25),
amount DECIMAL(6,2),
remarks VARCHAR(20)
)
SQLFiddle example
See MySQL String data types and MySQL numeric data types
check is a reserved work, that's why you have this error
you need to put quotes around it
CHECK is a reserved keyword in mysql. If you choose a different name it should work fine.

Syntax error due to using a reserved word as a table or column name in MySQL

I am trying to create a new table using the following:
CREATE TABLE onsale (
id INT AUTO_INCREMENT,
name VARCHAR(255),
desc TEXT,
image_file VARCHAR(255)
);
However, I keep getting an error:
ERROR 1064: (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB version for the right syntax to use near: 'desc TEXT, image_file VARCHAR(255))' at line 1
I don't see what is wrong with my syntax. It seems okay to me (obviously).
Can you tell me what I am doing wrong?
Thank you for your help.
The name you used for your column desc is a reserved word. You also need primary key (id):
CREATE TABLE onsale (
id INT AUTO_INCREMENT,
name VARCHAR(255),
description TEXT,
image_file VARCHAR(255),
primary key (id)
);
