i'm seeing a weird issue with phoenix, appreciate some thoughts
Created a simple table in phoenix
{noformat}
0: jdbc:phoenix:> create table test_select(nam VARCHAR(20), address VARCHAR(20), id BIGINT
. . . . . . . . > constraint my_pk primary key (id));
0: jdbc:phoenix:> upsert into test_select (nam, address,id) values('pulkit','badaun',1);
0: jdbc:phoenix:> select * from test_select;
+---------+----------+-----+
| NAM | ADDRESS | ID |
+---------+----------+-----+
| pulkit | badaun | 1 |
+---------+----------+-----+
0: jdbc:phoenix:> select distinct 'harshit' as "test_column", nam from test_select;
+--------------+---------+
| test_column | NAM |
+--------------+---------+
| harshit | pulkit |
+--------------+---------+
0: jdbc:phoenix:> select distinct 'harshit' as "test_column", trim(nam), trim(nam) from test_select;
+--------------+----------------+----------------+
| test_column | TRIM(NAM) | TRIM(NAM) |
+--------------+----------------+----------------+
| harshit | pulkitpulkit | pulkitpulkit |
+--------------+----------------+----------------+
{noformat}
When I apply a trim on the nam column and use it multiple times, the output has the cell data duplicated!
{noformat}
0: jdbc:phoenix:> select distinct 'harshit' as "test_column", trim(nam), trim(nam), trim(nam) from test_select;
+--------------+-----------------------+-----------------------+-----------------------+
| test_column | TRIM(NAM) | TRIM(NAM) | TRIM(NAM) |
+--------------+-----------------------+-----------------------+-----------------------+
| harshit | pulkitpulkitpulkit | pulkitpulkitpulkit | pulkitpulkitpulkit |
+--------------+-----------------------+-----------------------+-----------------------+
{noformat}
Wondering if someone has seen this before??
One thing to note is, if I remove the —— distinct 'harshit' as "test_column" —— The issue is not seen
{noformat}
0: jdbc:phoenix:> select trim(nam), trim(nam), trim(nam) from test_select;
+------------+------------+------------+
| TRIM(NAM) | TRIM(NAM) | TRIM(NAM) |
+------------+------------+------------+
| pulkit | pulkit | pulkit |
