[jira] [Created] (DRILL-8281) Info schema LIKE with ESCAPE push down bug

James Turton created DRILL-8281:
-----------------------------------

             Summary: Info schema LIKE with ESCAPE push down bug
                 Key: DRILL-8281
                 URL: https://issues.apache.org/jira/browse/DRILL-8281
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Information Schema
    Affects Versions: 1.20.2
            Reporter: James Turton
            Assignee: James Turton
             Fix For: 1.20.3


DRILL-8057 brought in a regression whereby info schema LIKE patterns containing an escape character are not correctly processed. For example if a storage plugin called dfs_foo (note the presence of the special '_') is present then the following query wrongly returns no records.
{code:java}
apache drill> show databases where schema_name like 'dfs^_foo.%' escape '^';
No rows selected (2.305 seconds){code}
