Is this the full SQL statement that you were trying? I was able to use:

create table test (`CREATE_TIMESTAMP` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP);

Here is console output

[root@centos6 bin]# idbmysql 
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Let me know if that does not work or you were trying the syntax in a different way. Also what version of InfiniDB are you trying?

Thanks!

It looks like you can't use timepstamp data types with InfiniDB. I have the same version as @mhoglan but it seems there is a little mistake in that query:

mysql> create table test (`CREATE_TIMESTAMP` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP);
Query OK, 0 rows affected (0.00 sec) 

is missing "engine=infinidb;" at the end, which would create the table in infinidb. Instead, the table is created using MySQL's default engine (MyISAM or whichever).

mysql> create table test (`CREATE_TIMESTAMP` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP) engine=infinidb;
ERROR 138 (HY000): The syntax or the data type(s) is not supported by InfiniDB. Please check the InfiniDB syntax guide for supported syntax or data types.

As you can see, adding engine=infinidb fails.

If you can use datetime instead that may be the way to go; timestamp doesn't appear to be supported right now :(

我猜这是InfiniDB中不允许的NOT NULL约束。
