  Hi,

  I have a column(Datatype - char(100)) in my table in which i am saving alphanumeric values like 'AKN12345', 'REC12345'. All these values are uploaded by the user from an excel file. How can i check whether the values entered is in scientific notation or not.

  Thanks in advance. !!

  Kind of an odd requirement to check for scientific notation. Not sure there is exact but maybe something like this?

  ;with SomeVals (CharVal)

  as (

  select 'AKN12345' union all

  select 'REC12345' union all

  select '12.47e43' union all

  select '12ee23' union all

  select '123jg756' union all

  select '837364.39485'

  )

  select CharVal, ISNUMERIC(CharVal) as Number, Case when ISNUMERIC(CharVal) = 1 and CharVal like '%e%' then 1 else 0 end as IsScientific

  from SomeVals
