  FROM [radiomix].[dbo].[chat] a
 inner JOIN [radiomix].[dbo].[MixFmProgram] p ON (a.DAY = p.ProgramWeekDay)
   WHERE a.ID = '381963'
 AND RIGHT(CONVERT(VARCHAR,a.datetimein,100),7) > p.ProgramStart

Is ProgramStart and ProgramEnd just varchars?  Because your comparing Greater / Less than with strings, not dates.


>>>  RIGHT(CONVERT(VARCHAR,a.datetimein,100),7) < p.ProgramEnd  <<<


try this: CAST(...) AS TIME, so this:


SELECT a.*
        ,p.*
        ,RIGHT(CONVERT(VARCHAR,[datetimein],100),7)
  FROM [radiomix].[dbo].[chat] a
 inner JOIN [radiomix].[dbo].[MixFmProgram] p ON (a.DAY = p.ProgramWeekDay)
   WHERE a.ID = '381963'
 AND CAST(RIGHT(CONVERT(VARCHAR,a.datetimein,100),7)) AS TIME > CAST(p.ProgramStart) AS TIME
  and CAST(RIGHT(CONVERT(VARCHAR,a.datetimein,100),7)) AS TIME < CAST(p.ProgramEnd) AS TIME

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

If you are just trying to compare times than using a style of 114 should be acceptable for comparisons.

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

select  CAST('02:00pm' AS time)
 CAST('02:00pm' AS datetime)

 Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '02:00pm'.

You do realize you are missing a comma, right?  As in:
select  CAST('02:00pm' AS time) ,
 CAST('02:00pm' AS datetime)
