Li Jin created SPARK-25216: ------------------------------ Summary: Provide better error message when a column contains dot and needs backticks quote Key: SPARK-25216 URL: https://issues.apache.org/jira/browse/SPARK-25216 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.4.0 Reporter: Li Jin
The current error message is often confusing to a new Spark user that a column containing "." needs backticks quote. For example, the current message looks like: {code:java} Cannot resolve column name "a.b" among (a.b) {code} We could improve the error message to, e.g: {code:java} Cannot resolve column name "a.b" among (a.b). Try adding backticks to the column name, i.e., `a.b`; {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
