Compare time stamps in MSSQL
1. I have to compare a timestamp field against a static (hardcoded time stamp) . Can u please advice.
eg Timestamp_fied > '2009-03-22 00:00:00.000' sometin lik this but i don get the correct values.
2. I also would like to dynamically compare the same timestamp field againsnt the current timestamp minus n days
eg Timestamp_fied > current_timestamp-1 ,sometin lik this but i don get the correct values.
eg Timestamp_fied > '2009-03-22 00:00:00.000' sometin lik this but i don get the correct values.

If you are refering to a column with the DATA_TYPE of TIMESTAMP then it is not a date value. See http://msdn.microsoft.com/en-us/library/ms182776(SQL.90).aspx for more details on TIMESTAMP. Comparing your string to a column of type DATETIME works for me so your problem must be TIMESTAMP.
How about casting the static timestamp in question?
SELECT *
where timestamp_field > CAST('2009-03-22 00:00:00.000' AS TIMESTAMP(0) FORMAT 'DD/MM/YYYYBHH:MI:SS');
SELECT *
where timestamp_field > CAST('2009-03-22 00:00:00.000' AS TIMESTAMP(0) FORMAT 'DD/MM/YYYYBHH:MI:SS');
Hi,
U can perform mathematical operations on Timesatmp in MSSQL.
Adding dates and subtracting dates can be achieved like simple addition.
< , > <= , >= and != can be use for comparinson also.

select Current_TIMESTAMP - 1
select Current_TIMESTAMP - 1 day
select Current_TIMESTAMP + 10 day
select Current_TIMESTAMP - 1 month
SELECT * FROM
NyTable WHERE MyDate > = GETDATE()
SELECT * FROM
NyTable WHERE MyDate > = Current_TIMESTAMP - 1 month
