[jira] [Created] (DRILL-1831) LIKE operator not working with SQL
[charlist] Wildcard
Rahul Challapalli created DRILL-1831:
----------------------------------------
Summary: LIKE operator not working with SQL [charlist] Wildcard
Key: DRILL-1831
URL: https://issues.apache.org/jira/browse/DRILL-1831
Project: Apache Drill
Issue Type: Bug
Components: Execution - Operators
Reporter: Rahul Challapalli
git.commit.id.abbrev=142e577
Data :
{code}
abc
def
acf
fgh
qjh
{code}
The below query works fine
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select columns[0] from `data-shapes/temp.tbl` where columns[0] like '%b%';
+------------+
| EXPR$0 |
+------------+
| abc |
+------------+
1 row selected (0.122 seconds)
{code}
However the below query does not return anything
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select columns[0] from `data-shapes/temp.tbl` where columns[0] like '[aq]%';
+------------+
| EXPR$0 |
+------------+
+------------+
No rows selected (0.139 seconds)
{code}
The above query should return values which start with either 'a' or 'q'.
Text Plan :
{code}
00-00 Screen
00-01 Project(EXPR$0=[$0])
00-02 SelectionVectorRemover
00-03 Filter(condition=[LIKE($0, '[aq]%')])
00-04 Project(ITEM=[ITEM($0, 0)])
00-05 Scan(groupscan=[EasyGroupScan [selectionRoot=/drill/testdata/data-shapes/temp.tbl, numFiles=1, columns=[`columns`[0]], files=[maprfs:/drill/testdata/data-shapes/temp.tbl]]])
{code}
Let me know if you need anything else
