db_drop_field

db_drop_field($table, $field)

Drops a field.

Parameters

$table: The table to be altered.

$field: The field to be dropped.

Return value

bool TRUE if the field was successfully dropped, FALSE if there was no field by that name to begin with.

Deprecated

as of Drupal 8.0.x, will be removed in Drupal 9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call dropField() on it. For example, $injected_database->schema()->dropField($table, $field);
