Set the default value for a field.

This implementation can't use ALTER TABLE directly, because SQLite only supports a limited subset of that command.

Übergabeparameter

$ret Array to which query results will be added.

$table The table to be altered.

$field The field to be altered.

$default Default value to be set. NULL for 'default NULL'.

Schema API

<?php
public function fieldSetDefault(&$ret, $table, $field, $default) {
  $new_schema = $this->introspectSchema($table);
  $new_schema['fields'][$field]['default'] = $default;
  $this->alterTable($ret, $table, $new_schema);
}
