-------------------------------------------
In Spark 3.3.0 the error message is improved scala> spark.sql("select TOP 1
from manager")
{code:java}
scala> spark.sql("select TOP 1 from manager")
org.apache.spark.sql.catalyst.parser.ParseException:
Syntax error at or near '1'(line 1, pos 11)
== SQL ==
select TOP 1 from manager
-----------^^^ {code}

> URL: https://issues.apache.org/jira/browse/SPARK-27908
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Yesheng Ma
> Priority: Major
>
> The {{SELECT TOP}} statement is actually not supported in Spark SQL. However,
> when a user queries such a statement, the error message is confusing. For
> example, the error message for
> {code:sql}
> SELECT TOP 1 FROM test;
> {code}
> is
> {code:java}
