# 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.
