----------------------------
Summary: calcite concat function
Key: CALCITE-3375
URL: https://issues.apache.org/jira/browse/CALCITE-3375
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.21.0
Reporter: cui
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
