> Issue when LIKE expression contains Chinese characters on Key column
> --------------------------------------------------------------------
>
> Key: PHOENIX-1334
> URL: https://issues.apache.org/jira/browse/PHOENIX-1334
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.1.0
> Environment: jdk 1.8 linux
> Reporter: wuyang
> Labels: Newbie
>
> When I use like expression in SELECT query. It works well when I put
> *Chinese* characters in LIKE expression on NONE PRIMARY KEY columns . BUT
> when I put them in LIKE expression on *PRIMARY KEY* , it occurs an Exception:
> select * from "test3" where PK like '中%';
> ||COLUMN_NAME||DATA_TYPE||TYPE_NAME
> |PK|12|VARCHAR
> |VAL|12|VARCHAR
> {quote}
> org.apache.phoenix.schema.IllegalDataException: CHAR types may only contain
> single byte characters (中)
> at org.apache.phoenix.schema.PDataType$2.toBytes(PDataType.java:216)

> {quote}
> the type of PRIMARY KEY and NONE PRIMARY KEY columns are all VARCHAR
> In the relative source code:
> {code}
> byte[] b = VARCHAR.toBytes(object);
> if (b.length != ((String) object).length()) {
> throw new IllegalDataException("CHAR types may only contain
> single byte characters (" + object + ")");
> }
> {code}
> actually, Chinese (or other non-Latin) characters will never meet the
> condition b.length == ((String) object).length() . Default encode method is
> UTF-8.
> *User following sentences to reappear:*
> create table "test_c" ( pk varchar primary key , val varchar);
> upsert into "test_c" values ('中文','中文');
> select * from "test_c" where VAL like '中%';
> _// it works well until now_
> select * from "test_c" where PK like '中%';
> _// oops..._
