Bill Schneider commented on SPARK-31367:
----------------------------------------
[~hyukjin.kwon] Why does DBMS support matter? octet_length looks like ANSI SQL
supported by PostgreSQL and MySQL.
But my case is the opposite problem. The function is already supported in
Spark SQL ("select octet_length(col) as foo from table") but NOT easily via
Scala code. What I want to do but can't is `withColumn("foo",
octet_length($"col"))`
> add octet_length to functions

> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 2.4.5, 3.0.0
> Reporter: Bill Schneider
> Priority: Major

> Many functions are available in statically-typed Scala code via
> org.apache.spark.sql.functions, for example `length`:

> I'm requesting `octet_length` to be included similarly.
