pyspark.sql.DataFrame.intersect

DataFrame.intersect(other: pyspark.sql.dataframe.DataFrame) → pyspark.sql.dataframe.DataFrame

Return a new DataFrame containing rows only in both this DataFrame and another DataFrame. Note that any duplicates are removed. To preserve duplicates use intersectAll().

New in version 1.3.0.

Changed in version 3.4.0: Supports Spark Connect.

Parameters

otherDataFrame

Another DataFrame that needs to be combined.

Returns

DataFrame

Combined DataFrame.

Notes

This is equivalent to INTERSECT in SQL.

Examples

>>> df1 = spark.createDataFrame([("a", 1), ("a", 1), ("b", 3), ("c", 4)], ["C1", "C2"])
>>> df2 = spark.createDataFrame([("a", 1), ("a", 1), ("b", 3)], ["C1", "C2"])
>>> df1.intersect(df2).sort(df1.C1.desc()).show()
+---+---+
| C1| C2|
+---+---+
|  b|  3|
|  a|  1|
+---+---+
