SQL Server FIFOtvf Function

Updated 2023-10-12 12:36:03.583000

Description

Use the table-valued function FIFOtvf to calculate running FIFO (First In, First Out) values in an ordered resultant table. FIFOtvf calculates balances for each value from the first value to the last value in the ordered group or partition. FIFOtvf returns:

    •     quantity on-hand

    •     inventory cost

    •     cost of goods sold

    •     gross margin on sale

    •     gross margin percentage

    •     average inventory price

    •     last inventory price

    •     cumulative cost of goods sold

    •     cumulative gross margin on sale

    •     cumulative gross margin percentage.

FIFOtvf supports both long and short inventory positions. In other words, if the quantity on hand falls below the zero, FIFOtvf calculates from the last sale or withdrawal transaction, rather than from the last purchases or additions to inventory.

FIFOtvf assumes that the quantity, i.e., the number of units of the transaction, and the monetary value of the transaction have the same sign. FIFOtvf adds NULL values to the inventory at the last price.

FIFOtvf requires monotonically ascending row numbers within a partition.

FIFOtvf resets all calculated values when the row number value is 1.

Syntax

SELECT * FROM [westclintech].[wct].[FIFOtvf] (
   <@DataQuery, nvarchar(max),>)

Arguments

@DataQuery

An SQL statement which returns a resultant table containing the unique transaction identifier, ROW_NUMBER(), quantity and amount.

Return Type

table

Remarks

If the 3rd column (quantity) of the resultant table from @DataQuery contains NULL an error will be generated.

This function relies on the SQL Server ROW_NUMBER() function and expects results to be returned in ascending ROW_NUMBER() order within a PARTITION.

When ROW_NUMBER() = 1 all inventory values are re-initialized.

Examples

Example #1

In the following examples, we calculate FIFO inventory values for stock trades in the ABC, XYZ, and GHI companies. We will create a temporary table, #c and populate it with some data. We can be either short or long the shares at any point in time.

--Create the temporary table
CREATE TABLE #c
(
    trn int,
    sym char(3),
    tDate date,
    qty money,
    price_unit money,
    price_extended money,
    PRIMARY KEY (trn)
);
--Populate the table with some data

Example #2

In this example, we will look at a simple FX blotter. In FX trading, it is not at all unusual to switch from a long currency position to a short currency position during the course of a day. Additionally, if you are trading something like the US dollars against the Euro, if you are long US dollars, you are short the Euro. Thus, it's critical to pay attention to the sign. We will create the #fx table and populate it with some data.

--Create the temporary table

This produces the following result.

Example #3

Using the #c temp table created in Example #1, we will insert the necessary input for the FIFOtvf into the #inv temp table containing an IDENTITY column which is then used to link the input data to the output data. This simplifies the @DataQuery SQL.

--put the #c data into #inv
SELECT IDENTITY(int, 1, 1) as id,
       trn,
       ROW_NUMBER() OVER (PARTITION by sym ORDER BY sym, tDate, trn) as rn,

       price_extended
