Summary: An issue for Spark SQL LIKE-with-ESCAPE clause
Key: SPARK-31210
URL: https://issues.apache.org/jira/browse/SPARK-31210
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.0.0
Reporter: Mingli Rui
I try to use LIKE with ESCAPE for Spark 3.0.0-preview2. But I find in it
doesn't work in below cases.
The database table
==============
create or replace table test_table_like ( subject string)
insert into $test_table_like values ('100 times'), ('1000 times'), ('100%')
Repro
====
val result2 = sparkSession.sql(
s"select * from test_table_like where subject like '100^%' escape '^' order by
1")
"100%" is expected to returned, but it doesn't. I debug into the code to check
the logical plan.
In the logical plan, the LIKE is transformed as "StartsWith(subject#130,
100^)". It looks it is incorrect.
