|
|
# types-1.*.*: Test that values are stored using the expected storage
|
|
# classes when various forms of literals are inserted into
|
|
# columns with different affinities.
|
|
# types-1.1.*: INSERT INTO <table> VALUES(...)
|
|
# types-1.2.*: INSERT INTO <table> SELECT...
|
|
# types-1.3.*: UPDATE <table> SET...
|
|
#
|
|
# types-2.*.*: Check that values can be stored and retrieving using the
|
|
# various storage classes.
|
|
# types-2.1.*: INTEGER
|
|
# types-2.2.*: REAL
|
|
# types-2.3.*: NULL
|
|
# types-2.4.*: TEXT
|
|
# types-2.5.*: Records with a few different storage classes.
|
|
#
|
|
# types-3.*: Test that the '=' operator respects manifest types.
|
