addNotNullConstraint doesn't work with mysql

General Discussion
1

I use Liquibase 2.0.5,

here’s snippet from my config:

  2.  <addNotNullConstraint columnDataType="VARCHAR(64)"
  3.                               columnName="permissions"
  4.                               defaultNullValue="ROLE_ADMIN"
  5.                               schemaName="users"
  6.                               tableName="apiTokens"/>
No errors or exceptions, but when I try to insert null into permissions column I receive:

ERROR 1048 (23000): Column ‘permissions’ cannot be null

  • but I need null to be replaced with my default value.

Please help.

Thanks a lot in advance
