# This file implements regression tests for SQLite library.
#
# This file implements tests for the "sqlite3_trace()" API. Specifically,
# it tests the special handling of nested SQL statements (those executed
# by virtual table or user function callbacks). These statements are treated
# differently in two respects:
#
#   1. Each line of the statement is prefixed with "-- " to turn it into
#      an SQL comment.
#
#   2. Parameter expansion is not performed.
