Julian Hyde closed CALCITE-3375.
--------------------------------
    Resolution: Invalid

This seems to be more of a question than a bug. Closing. Please ask the question on the dev list. We will re-open if we discover that there is a bug (i.e. we know the desired behavior and the observed behavior is different).

> I use calcite to connect mysql to test, I have two column test data , age(int) and name(varchar) and the table name is test.score_new, and I have two row test data following:
> --------------
> id	name	age
> --------------
> 1	飞	16
> --------------
> when I use the sql : select '飞'||16 or select '飞'||'16' , it will return the right result : EXPR$0=飞16
> But when I use the sql : select "name"||"age" from "test"."score_new", it will return the result : EXPR$0=1,
> and sql : select "sid"||"sid" from "test"."score_new", it will return : EXPR$0=1,
> and sql : select "name"||"name" from "test"."score_new", it will return : EXPR$0=0,
> the result is not what I want, I want to get the result : 飞16, why ? and How to solve this problem
