T-SQL

declare @thirtydaysago datetime declare @now datetime set @now = getdate() set @thirtydaysago = dateadd(day,-30,@now) select @now, @thirtydaysago 

or more simply

select dateadd(day, -30, getdate()) 

(DATEADD on BOL/MSDN)

MYSQL

SELECT DATE_ADD(NOW(), INTERVAL -30 DAY) 

( more DATE_ADD examples on ElectricToolbox.com)

In MS SQL Server, it is:

SELECT getdate() - 30;

SELECT (column name) FROM (table name) WHERE (column name) < DATEADD(Day,-30,GETDATE()); 

Example.

SELECT `name`, `phone`, `product` FROM `tbmMember` WHERE `dateofServicw` < (Day,-30,GETDATE()); 

Try adding this to your where clause:

dateadd(day, -30, getdate())
