I'm quite new to Redshift SQL.
select * from myredshift_tbl
where local_date between \'2016-01-01\' and \'2017-02-01\';
But got this error:
[amazon][500310] invalid operation syntax error at or near "\". I believe Redshift use single quote and I need to escape single quote.

The DATEDIFF function determines the number of date part boundaries crossed between two date/time expressions. This is perhaps unintuitive; for example, if we pass DATEDIFF(year, '2021-12-31', '2022-01-01') the function will return one year, even though there's only a single day difference.
select extract(minute from sysdate); -- hour, day, month, year, century select date_part(minute, sysdate); -- hour, day, month, year, century -- returns 0-6 (integer), where 0 is Sunday and 6 is Saturday SELECT extract(dow from sysdate); SELECT extract(dow, sysdate); -- returns a string like monday, tuesday, etc select ...
An interval is expressed as a combination of the INTERVAL keyword with a numeric quantity and a supported date part, for example INTERVAL '7 days' or INTERVAL '59 minutes' . You can connect several quantities and units to form a more precise interval, for example: INTERVAL '7 days, 3 hours, 59 minutes' .
If the column local_date is in date format, use:
select * from myredshift_tbl
where local_date between '2016-01-01' and '2017-02-01';
If the column local_date is timestamp:
select * from myredshift_tbl
where local_date between '2016-01-01 00:00:00' and '2017-02-01 23:59:59';
SELECT * FROM schemaName.TableName WHERE datetime > '2017-02-09
00:00:00' AND datetime < '2017-06-09 00:00:00';
The above query Works with Redshift to fetch all the entries in a table.
NOTE: The table I applied the query on had column/field 'datetime' of type 'timestamp'.
I tested this query on Redshift with the help of Workbench J.
