error when executing query getting following error:

the name 'select c1.claimtype,     sum(c1.jan) 'jan 2016-2017',sum(c1.feb) 'feb 2016-2017',sum(c1.mar) 'mar 2016-2017',     sum(c1.apr) 'apr 2016-2017',sum(c1.may) 'may 2016-2017',sum(c1.jun) 'jun 2016-2017',     sum(c1.jul) 'jul 2016-2017',sum(c1.aug) 'aug 2016-2017',sum(c1.sep) 'sep 2016-2017',     sum(c1.oct) 'oct 2016-2017',sum(c1.nov) 'nov 2016-2017',sum(c1.dec) 'dec 2016-2017',     sum(c1.total) 'total'     @claimsum c1 group c1.claimtype' not valid identifier.

i had replaced execute @squery execute (@squery) , working fine.
