<default-value> ::=
   <special-value>
   | <string>
   | <global variable>

   | <built-in-function>( <constant-expression> )
   | AUTOINCREMENT
   | CURRENT DATABASE
   | CURRENT REMOTE USER
   | NULL
   | TIMESTAMP
   | LAST USER

<special-value> ::=

   { DATE | TIME | TIMESTAMP | USER | PUBLISHER }
   | USER

Sample Source Patterns

Input Code:

Sybase

IN -> Sybase_01.sql

create table t_defaults
(
col1 timestamp default current utc timestamp,
col2 timestamp default current timestamp,
col3 varchar default current user,
col4 varchar default current remote user,
col5 varchar default last user,
col6 varchar default current publisher,
col7 varchar default current date,
col8 varchar default current database,
col9 varchar default current time,
col10 varchar default user,
col11 int default autoincrement,
col12 int identity,
col13 int default -10, 
col14 int default 'literal', 
col15 int default null
)
;

Output Code:
