| Hi I want to get i.e. 70% of the len of a string in a round amount.i.e. select 'testing123',round((len('testing123')/100 * 70),0) as length_thresholdshould return: testing123, 7 But with this code I only return 0. I need the length_Threshold to be a whole numberCan anybody help? |

| Also remember that the len function ignores trailing spaces.See what happens with this:select 'How long is 70% of a piece of string', round((len('How long is 70% of a piece of string') * 0.70), 0)select 'How long is 70% of a piece of string ', round((len('How long is 70% of a piece of string ') * 0.70), 0)Duane. |

| In case if you want to consider trailing sapces, use DATALENGTH instead on LENMadhivananFailing to plan is Planning to fail |
