Add a new field to a table.

Parameters

$table: Name of the table to be altered.

$field: Name of the field to be added.

$spec: The field specification array, as taken from a schema definition. The specification may also contain the key 'initial', the newly created field will be set to the value of the key in all rows. This is most useful for creating NOT NULL columns with no default value in existing tables. Alternatively, the 'initial_from_field' key may be used, which will auto-populate the new field with values from the specified field.

$keys_new: (optional) Keys and indexes specification to be created on the table along with adding the field. The format is the same as a table specification but without the 'fields' element. If you are adding a type 'serial' field, you MUST specify at least one key or index including it in this array. See ::changeField() for more explanation why.

Throws

\Drupal\Core\Database\SchemaObjectDoesNotExistException If the specified table doesn't exist.

\Drupal\Core\Database\SchemaObjectExistsException If the specified table already has a field by that name.
