> SPARK-28083 supported LIKE ... ESCAPE syntax
> {code:sql}
> spark-sql> SELECT '_Apache Spark_' like '__%Spark__' escape '_';
> true
> {code}
> but the `like` function can accept only 2 parameters. If we pass the third one, it fails with:
> {code:sql}
> spark-sql> SELECT like('_Apache Spark_', '__%Spark__', '_');
> Error in query: Invalid number of arguments for function like. Expected: 2; Found: 3; line 1 pos 7
> {code}
> The ticket aims to support the third parameter in `like` as `escapeChar`.
