Subject [jira] [Updated] (OPENJPA-2375) generate predictable names for primary and foreign keys
Date Thu, 25 Apr 2013 08:30:15 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-2375?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vermeulen updated OPENJPA-2375:
-------------------------------

    Description: 
When the MappingTool creates the database schema, OpenJPA will let the database determine
the names of primary and foreign key constraints. Microsoft SQL server uses a seemingly random
number which changes each time the database schema is generated. This makes it harder to create
SQL scripts that refer to these keys or use schema comparison tools.

Names of generated keys could e.g. be:
PK_<table name>
FK_<table name>_<foreign key column name(s)>

Names of generated keys could e.g. be:
PK_<table name>
FK_<table name>_<referenced foreign column name>
(Perhaps adding foreign table name as well to prevent possible name clashes)
