Is ProgramStart and ProgramEnd just varchars? Because your comparing Greater / Less than with strings, not dates.
>>> RIGHT(CONVERT(VARCHAR,a.da
try this: CAST(...) AS TIME, so this:

inner JOIN [radiomix].[dbo].[MixFmPro
WHERE a.ID = '381963'

the format of programstart and programend is like 1:00Am
and datetimein is a datetime i should get the time only and compare
and i have already have two field in each tables to check weekday !

If you treat that as a string then 9:00AM > 11:00AM or 9:00AM > 2:00PM Is that really what you want?

yes i have write this query if we can simplify it .. on convert and like this
the data stored in programstart is varchar type with format 1:00am 2:00pm
and i have a datetimein in another table with type datetime i should take the part time and compare

SELECT top 2 a.id,p.ProgramID,a.ProgramIDM
FROM [radiomix].[dbo].[chat] a
inner JOIN [radiomix].[dbo].[MixFmProgram] p ON (a.DAY = p.ProgramWeekDay)
WHERE
CONVERT(varchar,[datetimein], 114) >= convert(varchar, CONVERT(datetime,p.ProgramStart), 114)
and CONVERT(varchar,[datetimein], 114) < convert(varchar, CONVERT(datetime,p.ProgramEnd), 114 )
order by a.id desc
Active today
If you are just trying to compare times than using a style of 114 should be acceptable for comparisons.
if you can tell me how i can convert a varchar 2:00pm to hh:mm:ss 24hr
and same the datetime to a var char hh:mm:ss 24hr

You can convert 2:00pm to either time or datetime as follows:
CAST('02:00pm' AS time)
CAST('02:00pm' AS datetime)
