Description

git.commit.id.abbrev=142e577

Data :

abc
def
acf
fgh
qjh

The below query works fine

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)

However the below query does not return anything

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)

The above query should return values which start with either 'a' or 'q'.

Text Plan :

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]]])
