How do I conditionally create a table in Sybase (TSQL)?

Question

OK, so Sybase (12.5.4) will let me do the following to DROP a table if it already exists:

IF EXISTS (
    SELECT 1
    FROM sysobjects
    WHERE name = \'a_t

If you want to always create the table, but conditionally drop it, you can use:

IF(SELECT count(*) FROM sysobjects WHERE name="tableNameWithoutUserPart") > 0
    DROP TABLE tableNameWithUserPart
GO

CREATE TABLE tableNameWithUserPart ...
