Just getting around to adding this, but can’t figure out how to do this as part of my migration code:
Currently I have: userTable.addUniqueIndex("uniqueUser", userTable.existingColumnNamed("c_name")); Is there something along the lines of: userTable.addCaseInsensitiveUniqueIndex("uniqueUser", userTable.existingColumnNamed("c_name")); Or is there some way of adding such a constraint using EOModeler? thanks, Jeff > On Mar 27, 2017, at 3:52 AM, Musall, Maik <m...@selbstdenker.ag > <mailto:m...@selbstdenker.ag>> wrote: > > Hi, > > I would just create a unique function based index, like this: > > CREATE UNIQUE INDEX indexname ON MyTable( UPPER(columnName) ); > > No extensions required.
