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         


        

Answer 1

IF object_id('a_table') IS NULL
BEGIN
    CREATE TABLE a_table (
        col1 int not null,
        col2 int null
    ) 
END
