Even if sqlite3_column_rowid can sometimes not exactly identify a data
field, it can still do so reliably with the majority of queries IMHO.
It could at least do so much better than any other work-around I can
think of. This would finally enable applications to allow users
Hello Dennis,
please ignore my previous response - it is all wrong because I used the wrong
table definitions and data (see below for corrections). My appologies for this,
and thanks for holding on to sqlite3_column_rowid.

Consider these queries:
SELECT a.c2, b.c3 FROM a, b WHERE a.c1 = b.c1;
SELECT c1 + c2 FROM a;
Derrell,
I don't see a problem with either of your problem
Hello to all,
I would like to propose a new API function:
long long int sqlite3_column_rowid(sqlite3_stmt*, int iCol);
