Description:

def role_create(role, owner=None, grants=None, **kwargs):
    '''
    Creates a new database role.
    If no owner is specified, the role will be owned by the user that
    executes CREATE ROLE, which is the user argument or mssql.user option.
    grants is list of strings.

    CLI Example:

    .. code-block:: bash

        salt minion mssql.role_create role=product01 owner=sysdba grants='["SELECT", "INSERT", "UPDATE", "DELETE", "EXECUTE"]'
    '''
    if not grants:
        grants = []

    sql = 'CREATE ROLE {0}'.format(role)
    if owner:
        sql += ' AUTHORIZATION {0}'.format(owner)
    conn = None
    try:
        conn = _get_connection(**kwargs)
        conn.autocommit(True)
        # cur = conn.cursor()
        # cur.execute(sql)
        conn.cursor().execute(sql)
        for grant in grants:
            conn.cursor().execute('GRANT {0} TO [{1}]'.format(grant, role))
    except Exception as e:
        return 'Could not create the role: {0}'.format(e)
    finally:
        if conn:
            conn.autocommit(False)
            conn.close()
    return True
