Hi,

I try to run this but failed on converting.
May I know how can I solved this?

declare @test varchar(10)
set @test = 'Convert(date,ModifiedOn) >= 2012-02-13'
select top 10 ModifiedOn from Details
where ModifiedOn = @test

Error:
Conversion failed when converting date and/or time from character string

Increase the length

declare @test varchar(50)

What you are trying to do here?

It isn't possible this way without using dynamic sql.
But Senthil is right. Tell us what you want to do so we maybe can show a better way.

No, you're never too old to Yak'n'Roll if you're too young to die.

I would like to update the table to run certain date.
If is -1 it refers to yesterday date.
How if I would like to run from 1st Feb 2012 to yesterday date.

DECLARE @day varchar(100)
SET @day = '-1'
UPDATE tablename
SET columnname = 'SELECT * FROM tablename WHERE ModifiedDate = @day'
where ....

do you mean this?


DECLARE @day int
SET @day = -1

UPDATE t
SET t.columnname1 = value1,t.columnname2= value2,...
from tablename t
where t.ModifiedDate >= DATEADD(dd,DATEDIFF(dd,0,GETDATE())+@Day,0)
and t.ModifiedDate < DATEADD(dd,DATEDIFF(dd,0,GETDATE())+@Day+1,0)

this will work for any value of @day which will regarded as offset from current day
