> 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
> Priority: Major
>
> 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.
