DATATABLE code help

[MarkPalmberg]

Hi.

I'm just getting started with DATATABLE and am wondering about the following scenario:

Column A has 4 rows

1

2

3

4

Column B has 10 rows, multiple values for columns 3 (5) and 4 (3).

Is this doable with DATATABLE? Do I need Table Constructor instead? Here's what I have so far; I need multiple Gift Levels for my "Big" row...:

Gift Table = 
DATATABLE (
    "Gift Level Name", STRING,
    "Gift Level", STRING,
    "Gifts Needed", INTEGER,
    "Prospects Needed", INTEGER,
    "Dollars Needed", CURRENCY,
    "Cumulative Total", CURRENCY,
    {
        { "Biggest", "#####", #####, #####, #####, #####},
        { "Bigger", "#####", #####, #####, #####, ##### },
        { "Big", "#####", #####, #####, #####, #####}
    }
)

Thank you!

@MarkPalmberg ,

Not sure I understand what you are asking.

Here is what I get. Seems pretty cool.

Term	Definition
ColumnName	Any DAX expression that returns a table.
DataType	An enumeration that includes: INTEGER, DOUBLE, STRING, BOOLEAN, CURRENCY, DATETIME
Value	A single argument using Excel syntax for a one dimensional array constant, nested to provide an array of arrays. This argument represents the set of data values that will be in the table

For example,
{ {values in row1}, {values in row2}, {values in row3}, etc. }
Where {values in row1} is a comma delimited set of constant expressions, namely a combination of constants, combined with a handful of basic functions including DATE, TIME, and BLANK, as well as a plus operator between DATE and TIME and a unary minus operator so that negative values can be expressed.

The following are all valid values: 3, -5, BLANK(), "2009-04-15 02:45:21". Values may not refer to anything outside the immediate expression, and cannot refer to columns, tables, relationships, or anything else.

A missing value will be treated identically to BLANK(). For example, the following are the same: {1,2,BLANK(),4} {1,2,,4}

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

Sorry I wasn't very clear, @Nathaniel_C ! I need a table with multiple "Gift Level" values for my "Bigger" value in the "Level Name" column.

Thanks for taking a look at this; I appreciate your time.

Hi @MarkPalmberg ,

I guess I still don't understand. Could you dummy up a picture of your expected outlook?

Thanks,

Nathaniel

Reading your last reply turned on a lightbulb for me, @Nathaniel_C . *My* issue was that I was trying to shoehorn an Excel format into a Power BI table; see below. The answer simply seems to be (duh) to create multiple instances of my Bigger row:

Gift Table = 
DATATABLE (
    "Gift Level Name", STRING,
    "Gift Level", STRING,
    "Gifts Needed", INTEGER,
    "Prospects Needed", INTEGER,
    "Dollars Needed", CURRENCY,
    "Cumulative Total", CURRENCY,
    {
        { "Biggest", "#####1", #####, #####, #####, #####},
        { "Bigger", "#####1", #####, #####, #####, ##### },
        { "Bigger", "#####2", #####, #####, #####, ##### },
        { "Bigger", "#####3", #####, #####, #####, ##### },
        { "Big", "#####1", #####, #####, #####, #####},
        { "Big", "#####2", #####, #####, #####, #####},
        { "Big", "#####3", #####, #####, #####, #####}

    }
)

Wow! Does it work? Usually I might just have the first column on multiple rows.

Yes, "first column in multiple rows" is how it's going to have to work in Power BI, I think, Which is probably fine, maybe in a Matrix visualization? Now the trick will be if I can populate my numeric values with VARs when I create the table. I was thinking I read somewhere that I can. Like:

Gift Table = 
VAR BIGGER1 =
CALCULATE(
    SUM(SOMECOLUMN),
    SOMEFILTER)
RETURN
DATATABLE (
    "Gift Level Name", STRING,
    "Gift Level", STRING,
    "Gifts Needed", INTEGER,
    "Prospects Needed", INTEGER,
    "Dollars Needed", CURRENCY,
    "Cumulative Total", CURRENCY,
    {
        { "Biggest", "#####1", #####, #####, #####, #####},
        { "Bigger", BIGGER1, #####, #####, #####, ##### },
        { "Bigger", "#####2", #####, #####, #####, ##### },
        { "Bigger", "#####3", #####, #####, #####, ##### },
        { "Big", "#####1", #####, #####, #####, #####},
        { "Big", "#####2", #####, #####, #####, #####},
        { "Big", "#####3", #####, #####, #####, #####}

    }
)

Thanks for your replies, @Nathaniel_C !

Unlike DATATABLE, Table Constructor allows any scalar expressions as input values. Seems like you have to enumerate the type in DATATABLE.
