|
| -# This file implements regression tests for SQLite library.
|
| -#
|
| -# This file implements tests to verify that table column values
|
| -# are pulled out of the database correctly.
|
| -#
|
| -# Long ago, the OP_Column opcode was sufficient to pull out the
|
| -# value of a table column. But then we added the ALTER TABLE ADD COLUMN
|
| -# feature. An added column might not actually exist in every row,
|
| -# and so the OP_Column opcode has to contain a default value. Later
|
| -# still we added a feature whereby a REAL value with no fractional
|
| -# part is stored in the database file as an integer to save space.
|
| -# After extracting the value, we have to call OP_RealAffinity to
|
| -# convert it back to a REAL.
|
| -#
|
| -# The sqlite3ExprCodeGetColumn() routine was added to take care of
|
| -# all of the complications above. The tests in this file attempt
|
| -# to verify that sqlite3ExprCodeGetColumn() is used instead of a
|
| -# raw OP_Column in all places where a table column is extracted from
|
| -# the database.
