Look at the following built-in functions:
FIRST_DAY
LAST_DAY

SELECT 
  D
, FIRST_DAY (D)                     AS D_FIRST
, D - DAY (D) + 1                   AS D_FIRST_ALT
, LAST_DAY (D)                      AS D_LAST
, D - (DAY (D) - 1) + 1 MONTH - 1   AS D_LAST_ALT
FROM (VALUES CURRENT DATE) T (D)
