### Is your feature request related to a problem or challenge? As @adriangb observes in https://github.com/apache/datafusion/pull/12978, there is often special case handling for equality predicates like `col = 'foo'` However, sometimes people (or tools) write queries using the `LIKE` operator: ```sql SELECT ... WHERE col like 'foo' ``` ### Describe the solution you'd like I think it would be nice if DataFusion's simplifier could simplify such expressions to `WHERE col = 'foo'`, something that trino does (see https://github.com/trinodb/trino/commit/6aea881752ef9a83521a4a20bccf510bf9a31d2c#diff-3b166584d367d2e1bf2184249d6bad632bb4ecbe18e011f4744fdf629c771ce7R912) ``` > explain select * from values ('foo'), ('bar') where column1 like 'foo'; +---------------+---------------------------------------------+ | plan_type | plan | +---------------+---------------------------------------------+ | logical_plan | Filter: column1 LIKE Utf8("foo") | | | Values: (Utf8("foo")), (Utf8("bar")) | | physical_plan | CoalesceBatchesExec: target_batch_size=8192 | | | FilterExec: column1@0 LIKE foo | | | ValuesExec | | | | +---------------+---------------------------------------------+ 2 row(s) fetched.
