# AnalysisException: "Temporary table 'people' already exists;"

spark.catalog.dropTempView("people")
# True
df.createTempView("people")

df1 = spark.createDataFrame([(1, "John"), (2, "Jane")], schema=["id", "name"])
df2 = spark.createDataFrame([(3, "Jake"), (4, "Jill")], schema=["id", "name"])
df1.createTempView("table1")
df2.createTempView("table2")
result_df = spark.table("table1").union(spark.table("table2"))
result_df.show()
