sql - How can I compare the trimmed and untrimmed lengths of fields without retyping the field name? -

-

basically, want check if there spaces right of text in varchar field. so, want compare datalength(fieldname) datalength(rtrim(fieldname)).

this isn’t hard.

only thing is, need varchar fields in 5 tables. comes out 250 fields need compare way. there way can put field names 1 query without typing each one’s name 2x?

i'm using query names of fields need at.

select name sys.columns object_id =      (select object_id sys.tables name='tablename')  , system_type_id = 167

(using sql server 2005)

thanks!

i let sql server generate code me if it's typing problem:

select     'select * ' + o.name + ' datalength(' + c.name + ') > datalength(rtrim(' + c.name + '))'     sys.objects o inner join sys.columns c on     c.object_id = o.object_id ,     c.system_type_id = 167     o.name = 'tablename'

are sure type 167 need check though?
