how can i set constraint

[Pal Infocom Technologies-2]

how can i set a column constraint on table so that it accepts unique values only

[Jacques Le Roux]

Just create a isUnique method in UtilValidate Class and set the validate atribute in your entity with it.

There is another way creating a new field type : BTW this might be contributed, just create a Jira issue and a patch ;o)
