Proposed changes

Issue Number: close #xxx

Problem summary

fix bug:

create table t ( id int, k1 int ) distributed by hash(id) buckets 4 properties(...)

create view v1 as select cast(k1 as varchar) k1 from t1 select k1 from v1

which will cause 'Failed analysis when expr subsitution' because inlineViewDef always change string-like type to char.
