If a query is sorted on an index is there any advantage to including LIMIT in the stmt as opposed to omitting it and stepping through the result set LIMIT times?
No -- LIMIT appends an additional opcode to check the number of rows and introduces an effort related to an additional parsing. In general, LIMIT can reduce a cost of a full external sorting, however this does not apply to your query.
BTW, in file ``src/select.c'' line 2377: Expr *pLimit; /* Saved values of p->nLimit */ should be Expr *pLimit; /* Saved values of p->pLimit */ -- best regards Cezary H.
