Review Comment:
Oh... actually it's not wrong example.
We should backquotes for value when the value contains invalid syntax as
below:
```scala
scala> sql("SET a=`1;2;;`").show()
+---+-----+
|key|value|
+---+-----+
| a|1;2;;|
+---+-----+
```
Otherwise it raises error:
```scala
scala> sql("SET a=1;2;;")
org.apache.spark.sql.catalyst.parser.ParseException:
[INVALID_SET_SYNTAX] Expected format is 'SET', 'SET key', or 'SET
key=value'. If you want to include special characters in key, or include
semicolon in value, please use quotes, e.g., SET `key`=`value`.(line 1, pos 0)
== SQL ==
SET a=1;2;;

```
