ERROR 1366 (HY000): Incorrect integer value: '' for column 'id' at row 1 [closed]

Question

My code:

$sql = "INSERT INTO ". static::$table_name ." (";
$sql .= join(", ", array_keys($attributes));
$sql .= ") VALUES ('";
$sql .= join("', '", array_values($attributes));
$sql .= "')";

output:

echo $sql;
//INSERT INTO users (id, username, password, first_name, last_name)
VALUES ('', 'lukeduke', '123456', 'Luke', 'Duke')

When I run this query, I get:

ERROR 1366 (HY000): Incorrect integer value: '' for column 'id' at row 1

Answer 1

If you want to use this insert, you must provide an integer value in your sql instead of an empty string, it should by like this:

INSERT INTO users (id, username, password, first_name, last_name)
VALUES (1, 'lukeduke', '123456', 'Luke', 'Duke')

or if your id is autoincremental you can have your sql like this:

INSERT INTO users (username, password, first_name, last_name)
VALUES ('lukeduke', '123456', 'Luke', 'Duke')

In this case, this should be your code:

//extracting your first element of the array (id in this case)
$attributes = array_slice($attributes, 1);

$sql = "INSERT INTO ". static::$table_name ." (";
$sql .= join(", ", array_keys($attributes));
$sql .= ") VALUES ('";
$sql .= join("', '", array_values($attributes));
$sql .= "')";

Answer 2

what is your id column type?

if it is integer and auto increment, pass null value to it
