[jira] Updated: (DDLUTILS-85) Add support for unique constraints

     [ http://issues.apache.org/jira/browse/DDLUTILS-85?page=all ]

Thomas Dudziak updated DDLUTILS-85:
-----------------------------------

    Summary: Add support for unique constraints  (was: Unique index generated as index or as constraint.)

A unique index is not the same as a unique constraint. The latter is only intended to ensure that "combination of values in the indicated columns is unique across the whole table" to cite the PostgreSQL docs. The former adds an index on top of that.
