Question

While creating a table I am getting the following error:

ERROR 1293 (HY000): Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause

The problem is that I don’t actually have two columns TIMESTAMP with CURRENT_TIMESTAMP as default, neither I am using ON UPDATE clause.

The DDL query I’m trying to execute is

CREATE TABLE user(
    /* Basic Information */
    id INT NOT NULL AUTO_INCREMENT,
    firstname VARCHAR(255) NOT NULL,
    surname VARCHAR(255) NOT NULL,
    email VARCHAR(255) NOT NULL UNIQUE,
    username VARCHAR(255) NOT NULL UNIQUE,
    password CHAR(40) NOT NULL,

    /* System status information */
    active BOOL NOT NULL DEFAULT FALSE,
    validated BOOL NOT NULL DEFAULT FALSE,
    date_validated TIMESTAMP,
    date_registered TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,

    /* Index */
    PRIMARY KEY (id)
) Engine=InnoDB;

What’s causing the issue?

Answer 1

You can use two timestamp in one table. For default, use DEFAULT field first and then the rest timestamp fields.

Below query should work.

CREATE TABLE myTable 
(
 id INT,
 date_registered TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, 
 date_validated TIMESTAMP
);
