# At one point (between versions 3.6.18 and 3.6.20 inclusive), an UPDATE

# The following tests seek to verify that constant values (i.e. literals)

# are not factored out of loops within trigger programs. SQLite does
|
|
# not factor constants out of loops within trigger programs as it may only
|
|
# do so in code generated before the first table or index is opened. And
|
|
# by the time a trigger program is coded, at least one table or index has
|
|
# always been opened.
|
|
#
|
|
# At one point, due to a bug allowing constant factoring within triggers,
|
|
# the following SQL would produce the wrong result.
