示例1: escapeField
/**
* {@inheritdoc}
*/
public function escapeField($field)
{
$escaped = parent::escapeField($field);
// Remove any invalid start character.
$escaped = preg_replace('/^[^A-Za-z0-9_]/', '', $escaped);
// The pgsql database driver does not support field names that contain
// periods (supported by PostgreSQL server) because this method may be
// called by a field with a table alias as part of SQL conditions or
// order by statements. This will consider a period as a table alias
// identifier, and split the string at the first period.
if (preg_match('/^([A-Za-z0-9_]+)"?[.]"?([A-Za-z0-9_.]+)/', $escaped, $parts)) {
$table = $parts[1];
$column = $parts[2];
// Use escape alias because escapeField may contain multiple periods that
// need to be escaped.
$escaped = $this->escapeTable($table) . '.' . $this->escapeAlias($column);
} elseif (preg_match('/[A-Z]/', $escaped)) {
// Quote the field name for case-sensitivity.
$escaped = '"' . $escaped . '"';
}
return $escaped;
