  Quick suggestion

  😎

  USE TEEST;

  GO

  SET NOCOUNT ON;

  ;WITH SAMPLE_DATA(TIMESTR) AS

  (

  SELECT '00:10' UNION ALL

  SELECT '01:01' UNION ALL

  SELECT '02:01' UNION ALL

  SELECT '10:02' UNION ALL

  SELECT '12:00' UNION ALL

  SELECT '24:59'

  )

  SELECT

  SD.TIMESTR

  ,CASE

  WHEN CONVERT(INT,LEFT(SD.TIMESTR,2),0) = 0 THEN ''

  WHEN CONVERT(INT,LEFT(SD.TIMESTR,2),0) = 1 THEN '1 hour'

  WHEN CONVERT(INT,LEFT(SD.TIMESTR,2),0) > 1 THEN LEFT(SD.TIMESTR,2) + ' hours'

  END +

  CASE

  WHEN CONVERT(INT,LEFT(SD.TIMESTR,2),0) > 0 AND CONVERT(INT,RIGHT(SD.TIMESTR,2),0) > 0 THEN ' and '

  ELSE ''

  END +

  CASE

  WHEN CONVERT(INT,RIGHT(SD.TIMESTR,2),0) = 0 THEN ''

  WHEN CONVERT(INT,RIGHT(SD.TIMESTR,2),0) = 1 THEN '1 minute'

  WHEN CONVERT(INT,RIGHT(SD.TIMESTR,2),0) > 1 THEN RIGHT(SD.TIMESTR,2) + ' minutes'

  END AS TIME_OUT

  FROM SAMPLE_DATA SD;

  Output

  TIMESTR TIME_OUT

  ------- -----------------------

  00:10 10 minutes

  01:01 1 hour and 1 minute

  02:01 02 hours and 1 minute

  10:02 10 hours and 02 minutes

  If the input string is limited to less than 24 hours, the following makes life pretty easy and will also produce an error if someone entered improper information that result in more than 24 hours or more than 59 minutes.

  WITH SAMPLE_DATA(TIMESTR) AS

  (

  SELECT '00:10' UNION ALL

  SELECT '01:01' UNION ALL

  SELECT '02:01' UNION ALL

  SELECT '10:02' UNION ALL

  SELECT '12:00' UNION ALL

  SELECT '23:59'

  )

  SELECT DATENAME(hh,TimeStr) + ' Hour(s) and ' + DATENAME(mi, TimeStr) + ' Minute(s)'

  FROM Sample_Data

  ;

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
