contains
The name of the schema is first checked for an exact lexicographical match. If a match occurs, the schema is returned. If a lexicographical match fails, then a check for a match ignoring the case of the string is performed. This is done because SQL identifier names should be case-insensitive. If neither matches then false is returned.
Uses the longLastingConnection property for the connection.
