Is there a way to set the NULL_DISTINCT_FOR_UNIQUE to 1 for UNIQUE constraints to handle null as a distinct value? I found a really old link that shows this, but I cant figure out how to set it. I dont see it in the sqlite3.h header file anywhere:
http://web.utk.edu/~jplyon/sqlite/sqlite_api.html
Id like for my table to handle NULL as a unique for a table level constraint.
The symbol NULL_DISTINCT_FOR_UNIQUE doesn’t seem to be defined in the current version of the source code. I suppose it could have been renamed or moved from sqlite.h to a different file.
Looks like it might have been removed in 3.6.23.
You can download the source and look through sqlite3.h for something similar.
