> Mixed-cased alias doesn't work in select statement of “INNER JOIN”. Following
> are the repro steps.
> *1. Setup: Create tables and views.*
>
> {code:java}
> CREATE TABLE T1 (ID CHAR(256) PRIMARY KEY, "F".DUMMY_COLUMN VARCHAR);
> CREATE VIEW V1(ROWKEY VARCHAR PRIMARY KEY,F.COL1 VARCHAR,F.COL2
> VARCHAR,F.COL3 VARCHAR) AS SELECT * FROM T1;
> CREATE TABLE T2 (ID CHAR(256) PRIMARY KEY, "F2".DUMMY_COLUMN VARCHAR);
> CREATE VIEW V2(ROWKEY VARCHAR PRIMARY KEY,F2.COL1 VARCHAR,F2.COL2
> VARCHAR,F2.COL3 VARCHAR) AS SELECT * FROM T2; {code}
> *2. Execute query - Alias name without quotes, which are treated as UPPERCASE
> internally*
> {code:java}
> SELECT MixedCaseAlias1."COL1" as "MixedCaseAlias1_COL1",
> "MixedCaseAlias2"."COL2" as "MixedCaseAlias2_COL2", "MixedCaseAlias2"."COL3"
> as "MixedCaseAlias2_COL3" FROM (SELECT "COL1", "COL2" FROM V1) AS
> MixedCaseAlias1 INNER JOIN V2 AS "MixedCaseAlias2" on (MixedCaseAlias1."COL1"
> = "MixedCaseAlias2"."COL1") {code}
> {+}Result{+}: Query is executed successfully
> {code:java}
> jdbc:phoenix:> SELECT MixedCaseAlias1."COL1" as "MixedCaseAlias1_COL1",
> "MixedCaseAlias2"."COL2" as "MixedCaseAlias2_COL2", "MixedCaseAlias2"."COL3"
> as "MixedCaseAlias2_COL3" FROM (SELECT "COL1", "COL2" FROM V1) AS
> MixedCaseAlias1 INNER JOIN V2 AS "MixedCaseAlias2" on (MixedCaseAlias1."COL1"
> = "MixedCaseAlias2"."COL1");
> +----------------------+----------------------+----------------------+
> | MixedCaseAlias1_COL1 | MixedCaseAlias2_COL2 | MixedCaseAlias2_COL3 |
> +----------------------+----------------------+----------------------+
> +----------------------+----------------------+----------------------+
> No rows selected (0.258 seconds)
> 0: jdbc:phoenix:> {code}
>
> *3. Execute Problematic query - Alias name with quotes, which are not
> converted to UPPERCASE*
> {code:java}
> SELECT "MixedCaseAlias1"."COL1" as "MixedCaseAlias1_COL1",
> "MixedCaseAlias2"."COL2" as "MixedCaseAlias2_COL2", "MixedCaseAlias2"."COL3"
> as "MixedCaseAlias2_COL3" FROM (SELECT "COL1", "COL2" FROM V1) AS
> "MixedCaseAlias1" INNER JOIN V2 AS "MixedCaseAlias2" on
> ("MixedCaseAlias1"."COL1" = "MixedCaseAlias2"."COL1") {code}
> {+}Result{+}: Got exception

> "MixedCaseAlias1" INNER JOIN V2 AS "MixedCaseAlias2" on
> ("MixedCaseAlias1"."COL1" = "MixedCaseAlias2"."COL1")
