Burak Yavuz created SPARK-18952: ----------------------------------- Summary: regex strings not properly escaped in codegen Key: SPARK-18952 URL: https://issues.apache.org/jira/browse/SPARK-18952 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.0.2 Reporter: Burak Yavuz
If I use the function regexp_extract, and then in my regex string, use `\`, i.e. escape character, this fails codegen, because the `\` character is not properly escaped when codegen'd.
