I try to create table in mysql with the following command:
CREATE TABLE keys (id INT(10), key VARCHAR(100));
and it always gives me an error like this:
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 'keys (id INT(10), key VARCHAR(100))' at line 1`
So both the table name keys and the field key are reserved in the Mysql namespace. If you choose a different table name (e.g. keys_tbl) and rename the second field something like key_id, your code will work.
You should be very carefully with table and columns naming, you might face a lot of problems in the future.
I suggest find names that are not MySQL reserved words
If you still want to keep the names you should put in in backticks.
mysql> CREATE TABLE keys (id INT(10), key VARCHAR(100));
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 'keys (id INT(10), key VARCHAR(100))' at line 1

How to add not null constraint to existing column in MySQL
(3 answers)
Closed 3 years ago.
I need to make column called start_date_data_id to be nullable.
I found this answer(Altering a column to be nullable) and tried to do it on described way.
Description of that column: (| start_date_data_id| bigint(20)| NO | MUL | NULL | |).
Query:
ALTER TABLE attenddb.company_group_user_settings
ALTER COLUMN start_date_data_id bigint(20) NULL;
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 'bigint(20) NULL' at line 1
Can someone tell me why is it not working?
Try this:
ALTER TABLE attenddb.company_group_user_settings
MODIFY start_date_data_id bigint(20) NULL;

No matter how I fiddle around with the syntax I can't seem to figure it out. I feel like it's a total rookie mistake but I need help. Thank you.
You have an extra comma after the last field definition in every single create table statement, therefore none of the tables are created and none of the insert can succeed.
Example:
...
location varchar(64) not null, <- this comma
);
You also use backticks around the values to be inserted incorrectly. Backticks are used to enclose object identifiers, such as table or field names. String values should be enclosed by single or double quotes, numeric values should not be enclosed.
Example:
insert into caller (firstname, lastname, cellnumber, location)
values ('Braydon', 'Rekart', 2174088935, 'Stoddard');

How do I escape reserved words used as column names? MySQL/Create Table
(4 answers)
Closed 6 years ago.
I would like to create a table with GENERATED as column in MySQL version 5.7.16. When I try below query it is giving error:
create table madhu (RECORDID VARCHAR(255) NOT NULL, GENERATED INTEGER NOT NULL);
Below is the error:
Error Code: 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 'GENERATED INTEGER NOT NULL)' at line 1 0.000 sec
It looks GENERATED is reserved key word. Is there away to have GENERATED as column? If I change the column it works anyway.
To escape reserved keywords use backticks or choose a different column name.
create table madhu
(
RECORDID VARCHAR(255) NOT NULL,
`GENERATED` INTEGER NOT NULL
);
IF COL_LENGTH('Characters', 'name') IS NULL
BEGIN
ALTER TABLE `Characters` ADD `name` INT(32) UNSIGNED NOT NULL;
END
I am trying to write some sql that will insert a column name into the table "Characters" if it is not already existant, however I am getting errors which I do not understand (quite new to SQL) and I could use some help understanding why it is not working. I have gotten the IF part from another Question, and the ALTER part from the DBMS I'm using, PhpMyAdmin 2.11.4.
It is using MySQL 5.6 apparently and this is the error:
MySQL said: Documentation
#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 'IF COL_LENGTH('Characters', 'name') IS NULL
