I downloaded SqlLite 3.7.3 and allegedly the best .NET wrapper for this database engine. I put them in the same directory and ran their provided test.exe.

Most tests succeeded, but two failed. FunctionWithCollation failed with SQLite error "no such function: CHARINDEX" and FunctionWithCollation2 failed with "The method or operation is not implemented".

The support site is silent and so is google. Does anybody have an idea what that means, and how if at all should I proceed?

First of all it would be very good to mention what are FunctionWithCollation and FunctionWithCollation2 do so it would be easier to see what happens.

AFAIK sqlite3 does not support collation built-in as it is quite hard thing to do and allows you to plug in your own collation functionality: http://www.sqlite.org/c3ref/create_collation.html, AFAIK there are some ICU based collation providers.

So check this direction if it does not require you do add some plugin or so.

EDIT: From quick glance to the source code, the unit tests do some testing on charindex function. This function is extension, so:

  • It seems a problem with either build or with the program or combination of them
  • I don't think you should care unless you are using extensions. See: http://www.sqlite.org/contrib
  • In any case I would suggest filling a bug.
