CREATE TABLE table_49340 ("Week" FLOAT, "Date" CLOB, "Opponent" CLOB, "Result" CLOB, "Attendance" FLOAT)

Can you tell me the Date that has the Week smaller than 13, and the Opponent of green bay packers?
SELECT "Date" FROM table_49340 WHERE "Week" < '13' AND "Opponent" = 'green bay packers'
SELECT "Date" FROM "table_49340" WHERE "Opponent" = 'green bay packers' AND "Week" < '13'
