      Description

      If I have a column where some rows contain a newline, then using a % does not match as it should. For example, if I have a column named 'foo' where a row contains 'My\nValue' then the following query I would expect to match:

      SELECT * FROM MyTable WHERE foo LIKE 'M%'

      However, this row is not returned by the above query. This appears to be a bug in the regex generated by the org.apache.calcite.runtime.Like class, as it generates '.*' for the %, but in Java the dot character does not match newlines unless it is compiled in dot-all mode.
