What is the difference between rowsBetween and rangeBetween?

From the PySpark docs rangeBetween:

rangeBetween(start, end)

Defines the frame boundaries, from start (inclusive) to end (inclusive).

Both start and end are relative from the current row. For example, "0" means "current row", while "-1" means one off before the current row, and "5" means the five off after the current row.

Parameters:

  • start – boundary start, inclusive. The frame is unbounded if this is -sys.maxsize (or lower).
  • end – boundary end, inclusive. The frame is unbounded if this is sys.maxsize (or higher). New in version 1.4.

while rowsBetween

rowsBetween(start, end)

Defines the frame boundaries, from start (inclusive) to end (inclusive).

Both start and end are relative positions from the current row. For example, "0" means "current row", while "-1" means the row before the current row, and "5" means the fifth row after the current row.

Parameters:

  • start – boundary start, inclusive. The frame is unbounded if this is -sys.maxsize (or lower).
  • end – boundary end, inclusive. The frame is unbounded if this is sys.maxsize (or higher). New in version 1.4.

For rangeBetween how is "1 off" different from "1 row", for example?

What is the Difference between ROWS and RANGE?, The default frame is RANGE BETWEEN UNBOUNDED PRECEDING AND if you specify ROWS BETWEEN UNBOUNDED PRECEDING AND  Summary In today’s blog posting you have seen the difference between the ROWS and RANGE option when you define your window frame for analytic calculations. With the ROWS option you define on a physical level how many rows are included in your window frame.

The Java spark docs add clarity: https://spark.apache.org/docs/2.3.0/api/java/org/apache/spark/sql/expressions/WindowSpec.html#rowsBetween-long-long-

rangeBetween

A range-based boundary is based on the actual value of the ORDER BY expression(s). An offset is used to alter the value of the ORDER BY expression, for instance if the current order by expression has a value of 10 and the lower bound offset is -3, the resulting lower bound for the current row will be 10 - 3 = 7. This however puts a number of constraints on the ORDER BY expressions: there can be only one expression and this expression must have a numerical data type. An exception can be made when the offset is unbounded, because no value modification is needed, in this case multiple and non-numeric ORDER BY expression are allowed.

rowBetween

A row based boundary is based on the position of the row within the partition. An offset indicates the number of rows above or below the current row, the frame for the current row starts or ends. For instance, given a row based sliding frame with a lower bound offset of -1 and a upper bound offset of +2. The frame for row with index 5 would range from index 4 to index 6.

What is the difference between rowsBetween and rangeBetween?, For rangeBetween how is "1 off" different from "1 row", for example? sql apache-​spark pyspark apache-spark-sql window-functions. and here comes the problem. I want to have a rangeBetween 7 days, but there is nothing in the Spark docs I could find on this. Does Spark even provide such option? For now I'm just getting all the preceding rows with:.rowsBetween(-sys.maxsize, 0) but would like to achieve something like:.rangeBetween("7 days", 0)

rowsBetween: - With rowsBetween you define a boundary frame of rows to calculate, which frame is calculated independently.

Frame in rowsBetween does not depend on orderBy clause.

df = spark.read.csv(r'C:\Users\akashSaini\Desktop\TT.csv',inferSchema =True, header=True).na.drop()
w =Window.partitionBy('DEPARTMENT').orderBy('SALARY').rowsBetween(Window.unboundedPreceding,Window.currentRow)
df.withColumn('RowsBetween', F.sum(df.SALARY).over(w)).show()


first_name|Department|Salary|RowsBetween|

 Sofia|     Sales| 20000| 20000|
Gordon|     Sales| 25000| 45000|
Gracie|     Sales| 25000| 70000|
Cellie|     Sales| 25000| 95000|
Jervis|     Sales| 30000|125000|
 Akash|  Analysis| 30000| 30000|
Richard|   Account| 12000| 12000|
 Joelly|   Account| 15000| 27000|
Carmiae|   Account| 15000| 42000|
    Bob|   Account| 20000| 62000|
  Gally|   Account| 28000| 90000

rangeBetween: - With rangeBetween, you define a boundary frame of rows to calculate, which may change.

Frame in rowsBetween depends on orderBy clause. rangeBetween will include all the rows which has same value in orderBy clause like Gordon, Gracie and Cellie have same salary so included with the current frame.

For more understanding see below example: -

df = spark.read.csv(r'C:\Users\asaini28.EAD\Desktop\TT.csv',inferSchema =True, header=True).na.drop()
w =Window.partitionBy('DEPARTMENT').orderBy('SALARY').rangeBetween(Window.unboundedPreceding,Window.currentRow)
df.withColumn('RangeBetween', F.sum(df.SALARY).over(w)).select('first_name','Department','Salary','Test').show()

 first_name|Department|Salary|RangeBetween|
  Sofia|     Sales| 20000| 20000|
 Gordon|     Sales| 25000| 95000|
 Gracie|     Sales| 25000| 95000|
 Cellie|     Sales| 25000| 95000|
 Jervis|     Sales| 30000|125000|
  Akash|  Analysis| 30000| 30000|
Richard|   Account| 12000| 12000|
 Joelly|   Account| 15000| 42000|
Carmiae|   Account| 15000| 42000|
    Bob|   Account| 20000| 62000|
  Gally|   Account| 28000| 90000|

Spark Window Functions - rangeBetween dates, I don't think that what you are asking for is directly possible(check this) in Spark or in Hive. Both require ORDER BY clause used with RANGE to  Dim r as Range Set r = Range("C2:D3") Dim r1 as Range, r2 as Range Set r1 = r.EntireColumn Set r2 = r.Columns Won't both ranges represent the range "C:D"? What is the difference between the two?

SQL Server Windowing Functions: ROWS vs. RANGE |, However I've never seen the so-called RANGE clause of analytic functions which is "RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW​". In order to clearly show the difference between ROWS and RANGE, I'll use an ROWS BETWEEN 5 PRECEDING AND 5 FOLLOWING) SUM5 It is simple: ROWS BETWEEN doesn't care about the exact values. It cares only about the order of rows, and takes fixed number of preceding and following rows when computing frame. RANGE BETWEEN considers values when computing frame.

ROWS vs RANGE Clause: SQL Exploration of Analytics, I have talked at KScope about the difference between ROWS and The effect of ROWS BETWEEN rather than the default RANGE BETWEEN  Re: Select Range Between Two Variable Cells. Hi, I realise this thread is quite old, but I haven't been able to find an answer to my problem, and maybe someone here can. I am essentially having the same problem as the OP, but with a small difference, which is what I believe is not allowing the macro to run properly.
