-- This file implements regression tests for sql library. The

-- ["set","testdir",[["file","dirname",["argv0"]]]]
-- ["source",[["testdir"],"\/tester.tcl"]]
-- Test plan:
--
-- count-0.*: Make sure count(*) works on an empty database. (Ticket #3774)
--
-- count-1.*: Test that the OP_Count instruction appears to work on both
-- tables and indexes. Test both when they contain 0 entries,
-- when all entries are on the root page, and when the b-tree
-- forms a structure 2 and 3 levels deep.
