Sybase Sequence

Question

I am creating a sequence in sybase but getting mentioned exception, can anyone please help?

CREATE OR REPLACE SEQUENCE dbo.event_id_sequence
    START WITH 100
    INCREMENT BY 1
    MINVALUE 100
    NO MAXVALUE
    NO CACHE  
    NO CYCLE    
go

GRANT USAGE ON SEQUENCE dbo.event_id_sequence TO userID maintenance
GRANT USAGE ON SEQUENCE dbo.event_id_sequence TO userID readonly
GRANT USAGE ON SEQUENCE dbo.event_id_sequence TO userID reports
go

Exception:

Answer 1

Sybase ASE does not have sequence , the code you found is likely pulled from Sybase IQ or possible SQL Anywhere.

Instead of using sequence , you should look at using IDENTITY columns instead.

If that does not suit your needs, Sybase suggests a number of other approaches that may give you what you are looking for.

Methods:

Methods which can be used to produce a monotonic series are:

Max Plus One

Enhanced Max Plus One

Next Key Table

Identity Property

All of these are detailed in the linked document.

I would also suggest reviewing page 20 of this presentation on Migration from Oracle to ASE from SAP Techwave. There is some sample code on how to emulate SEQUENCE using a sequence table/procedure.

CREATE TABLE my_seq (seq int) 
go 
//initialize the sequence 
INSERT INTO my_seq select 0 
go 
CREATE PROCEDURE get_seq (@seq int OUTPUT) 
AS UPDATE my_seq SET seq = seq+1 
SELECT @seq = seq FROM my_seq 
go 
// execute the sp to get the next sequence number 
DECLARE @seq int 
EXEC get_seq @seq OUTPUT 
INSERT INTO m_table VALUES (@seq,..) 
go
