Hi,
I posted this question last year, but did not get any feed back. Is this
something that can be handled on the ML, or should I ask in another place?

Subject: Exception when querying a range index
To: sqlite-users@sqlite.org
Hi All,
I have an application using sqlite to store coast lines (application runs
on windows and uses the .Net version of sqlite v1.0.83). I use range
indexes to look-up coast line within range of a given point.
During run time I find that the following exception occurs.
vtable constructor failed: MapLevel_Idx3
How is virtual table MapLevel_Idx3 created? Is it an rtree table?
SQLite version?
Dan.
Occurence ratio is about 1 in 10000 queries on the range index. Am I doing
something wrong, or is this supposed to be so? When the exception occurs, I
just drop the resultset and assume that no data was to be found. Should I
restart the query?
Regards,
