[GitHub] [pinot] kirkrodrigues opened a new issue, #10849: LIKE doesn't seem to support escaping SQL wildcards
kirkrodrigues opened a new issue, #10849:
URL: https://github.com/apache/pinot/issues/10849
A query like:
`SELECT * FROM table WHERE col LIKE '%2\_2%'`
gets translated to
`SELECT * FROM table WHERE REGEXP_LIKE(col, '2\\.2')`
Is this the right syntax for escaping SQL wildcards?
If so, this issue looks to be because [`likeToRegexpLike`](https://github.com/apache/pinot/blob/master/pinot-common/src/main/java/org/apache/pinot/common/utils/RegexpPatternConverterUtils.java#L35) doesn't handle escaped wildcards.

Good catch. I believe the problem is in `likeToRegexpLike` not handing escape properly. Seems `_` is not defined as a meta-character. cc @atris
