I just started to try DdlUtils. I encountered following problem:
A default NULL results in 'NULL' in the SQL code not in NULL without the
quotes.
<column name="organisation" type="VARCHAR" size="50" default="NULL"/>
results in SQL code
organisation VARCHAR(50) DEFAULT 'NULL',
How can I define the NULL value in the XML file, so it does not get
interpreted as a string value? Does exist some escape character? I
looked thru the documentation, in some source files, and searched the
mailing list, but didn't find anything. Did I overlook something?
SQL NULL is the default value if you do not specify one - there is no
other to specify it except by not specifying it.
I was not aware of this behavior.
Same problem with CURRENT_TIMESTAMP
<column name="timestamp" type="TIMESTAMP" default="CURRENT_TIMESTAMP"/>
results in SQL code
timestamp TIMESTAMP DEFAULT 'CURRENT_TIMESTAMP',
In general the default value is expected to be a string value that can
be converted to the Java type corresponding to the JDBC type (as
defined by the JDBC spec). What you need in this case would be a
nativeDefault attribute which is not interpreted by DdlUtils at all.
This is currently not possible, but you could add a feature request to
DdlUtils' JIRA.
I created a feature request.

cheers,
