------------------------------
Summary: Replace sql function requires backticks to avoid parse
error
Key: DRILL-1441
URL: https://issues.apache.org/jira/browse/DRILL-1441
Project: Apache Drill
Issue Type: Bug
Components: Functions - Drill
Reporter: Krystal
git.commit.id.abbrev=f8d38b6
Currently the "replace" function requires to be enclosed within backticks (ie.
`replace`); otherwise it would fail during the parsing.
For example the following query fails:
0: jdbc:drill:schema=M7> select replace(substring(name,1,10), 'or', 'EA') from
`dfs.default`.voter where name like 'victor%';
Query failed: Failure while parsing sql. Encountered "replace" at line 1,
column 8.
Was expecting one of:
"UNION" ...
"INTERSECT" ...
"EXCEPT" ...
.
.
.
The following modified query succeeds:
0: jdbc:drill:schema=M7> select `replace`(substring(name,1,10), 'or', 'EA')
from `dfs.default`.voter where name like 'victor%';
+------------+
| EXPR$0 |
+------------+
| victEA tho |
| victEA you |
| victEA rob |
| victEA van |
| victEA rob |
.
.
.
The parse error was originally filed in this jira:
https://issues.apache.org/jira/browse/DRILL-738. We should find a way to avoid
requiring backticks as this is a standard sql function.
