+# 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.
