Ivan Sadikov updated SPARK-39783:
---------------------------------
Description:
AnalysisException [UNRESOLVED_COLUMN] shows the wrong suggestion when a field
with the "." separator is referenced without backticks.
The following code references a nested value {{{}`the`.`id`{}}}, that does not
exist. The proposed / existing column names are not correctly wrapped in
backticks:
{code:scala}
Seq((0)).toDF("the.id")
.select("the.id").show()
org.apache.spark.sql.AnalysisException: [UNRESOLVED_COLUMN] A column or
function parameter with name `the`.`id` cannot be resolved. Did you mean one of
the following? [`the`.`id`];
{code}
Instead of {{{}[`the`.`id`]{}}}, you would expect {{{}[`the.id`]{}}}.
Here an example where the nested column exists:
{code:scala}
spark.range(1).select(struct("id").as("the"))
.select("the.id").show()
+---+
| id|
+---+
| 0|
+---+
{code}
