Замечание
This function can not be called statically.
When using PEAR DB's sequence methods, we strongly advise using these methods for all procedures, including the creation of the sequences. Do not use PEAR DB's methods to access sequences that were created directly in the DBMS. See the warning on the "Intro - Sequences" page complete information.
