Why CTE is having issues with Databricks here?

[THIAM_HUATTAN]

df = spark.createDataFrame([(2018,'Apple1',45000),(2019,'Apple1',35000),(2020,'Apple1',75000),

              (2018,'Samsung',15000),(2019,'Samsung',20000),(2020,'Samsung',25000),

              (2018,'Nokia',21000),(2019,'Nokia',17000),(2020,'Nokia',14000)],

              ['Year', 'Brand', 'Sales'])

df.createOrReplaceTempView('PhoneBrandSales')

spark.sql('SELECT * FROM PhoneBrandSales').show()

%sql

SELECT *, 

Lead(Sales, 1, 0) 

OVER(PARTITION BY Brand ORDER BY Year desc) AS PreviousYearSales 

FROM PhoneBrandSales;

%sql

WITH CTE AS

(

 SELECT *,

 Lead(Sales, 1, 0)

 OVER(PARTITION BY Brand ORDER BY Year desc) AS PreviousYearSales

 FROM PhoneBrandSales;

)

SELECT * FROM CTE

ParseException:

no viable alternative at input 'WITH CTE AS\n(\n SELECT *, \n Lead(Sales, 1, 0) \n OVER(PARTITION BY Brand ORDER BY Year desc) AS PreviousYearSales \n FROM PhoneBrandSales'(line 6, pos 22)

== SQL ==

WITH CTE AS

(

SELECT *,

Lead(Sales, 1, 0)

OVER(PARTITION BY Brand ORDER BY Year desc) AS PreviousYearSales

FROM PhoneBrandSales

Issue is coming because of the semicolon beside PhoneBrandSales. Try removing that ; issue will be resolved. Please refer to the screenshot below.
