Krystal created DRILL-575:
-----------------------------
Summary: RPAD/LPAD functions fails when padded string is not
specified
Key: DRILL-575
URL: https://issues.apache.org/jira/browse/DRILL-575
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.0.0
Reporter: Krystal
In oracle and postgres, rpad and lpad functions defaults to spaces when str2 is
not specified - rpad(str1, length [, str2]). For example in oracle:
SQL> select rpad(name,20) from voter where voter_id=10;
RPAD(NAME,20)
--------------------
tom underhill
SQL> select lpad(name,20) from voter where voter_id=10;
LPAD(NAME,20)
--------------------
tom underhill
In drill, the queries fail because the str2 parameter is required:
0: jdbc:drill:schema=dfs> relect lpad(name, 20) from voter where voter_id=10;
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while
running query.[error_id: "dde5cf1c-1d05-46c4-902a-c4bd6621c065"
