### Actual Behavior

create table t1 (grp int, a bigint unsigned, c char(10) not null);
insert into t1 values (1,1,"a");
insert into t1 values (2,2,"b");
insert into t1 values (2,3,"c");
insert into t1 values (3,4,"E");
insert into t1 values (3,5,"C");
insert into t1 values (3,6,"D");
select sum(all a),count(all a),avg(all a),std(all a),variance(all a),bit_or(all a),bit_and(all a),min(all a),max(all a),min(all c),max(all c) from t1;

[SQL STATEMENT]: select sum(all a),count(all a),avg(all a),std(all a),variance(all a),bit_or(all a),bit_and(all a),min(all a),max(all a),min(all c),max(all c) from t1;
[EXPECT RESULT]:
sum(all a) count(all a) avg(all a) std(all a) variance(all a) bit_or(all a) bit_and(all a) min(all a) max(all a) min(all c) max(all c)

[ACTUAL RESULT]:
sum(all a) count(all a) avg(all a) std(all a) variance(all a) bit_or(all a) bit_and(all a) min(all a) max(all a) min(all c) max(all c)
