Teradata - Return records added since first of last month, but before

Question

I'm using Teradata 14, with the Teradata 13 client.

I want to pull all records from a table (it contains a time stamp), for the previous month. Something like:

SELECT COL1, COL2, DATECOL
FROM TABLE
WHERE DATECOL >= FIRST_OF_LAST_MONTH
    AND DATECOL IS < FIRST_OF_THIS_MONTH

Any help would be appreciated. I'm new to Teradata.

Answer 1

SELECT COL1, COL2, DATECOL
FROM TABLE
WHERE DATECOL >= ADD_MONTHS (CURRENT_DATE -EXTRACT(DAY FROM CURRENT_DATE) + 1 , -1)
AND DATECOL < CURRENT_DATE -EXTRACT(DAY FROM CURRENT_DATE) + 1

or you might just want to enter date

>=DATE '2014-05-01'
< DATE '2014-04-01'
