Question

我正在尝试创建时间表，以使过滤范围在0到23小时之间。这将是我的第一个问题，但是由于语法错误，我什至无法创建任何表。（我不记得该怎么做）。我正在使用Power BI Desktop，这是DAX计算的表语法：

DateTime = 
ADDCOLUMNS (
    CROSSJOIN(
        CALENDAR(DATE(2000;1;1);DATE(2025;12;31));
        UNION (
            ROW ( "Time"; TIME ( 1; 0; 0 ) );
            ROW ( "Time"; TIME ( 2; 0; 0 ) );
            ROW ( "Time"; TIME ( 3; 0; 0 ) );
            ROW ( "Time"; TIME ( 4; 0; 0 ) );
            ROW ( "Time"; TIME ( 5; 0; 0 ) );
            ROW ( "Time"; TIME ( 6; 0; 0 ) );
            ROW ( "Time"; TIME ( 7; 0; 0 ) );
            ROW ( "Time"; TIME ( 9; 0; 0 ) );
            ROW ( "Time"; TIME ( 10; 0; 0 ) );
            ROW ( "Time"; TIME ( 11; 0; 0 ) );
            ROW ( "Time"; TIME ( 12; 0; 0 ) );
            ROW ( "Time"; TIME ( 13; 0; 0 ) );
            ROW ( "Time"; TIME ( 14; 0; 0 ) );
            ROW ( "Time"; TIME ( 15; 0; 0 ) );
            ROW ( "Time"; TIME ( 16; 0; 0 ) );
            ROW ( "Time"; TIME ( 17; 0; 0 ) );
            ROW ( "Time"; TIME ( 18; 0; 0 ) );
            ROW ( "Time"; TIME ( 19; 0; 0 ) );
            ROW ( "Time"; TIME ( 20; 0; 0 ) );
            ROW ( "Time"; TIME ( 21; 0; 0 ) );
            ROW ( "Time"; TIME ( 22; 0; 0 ) );
            ROW ( "Time"; TIME ( 23; 0; 0 ) );
            ROW ( "Time"; TIME ( 24; 0; 0 ) )
        )
    );
    "DateTime"; [Date] + [Time];
    "Hour"; HOUR ( [Time] )
)

这使我在上出现语法错误；（我也尝试过“，”）。我敢肯定，有些简单的东西我写错了，错误在哪里？谢谢

我尝试使用此代码（从互联网粘贴），但此方法无效：

DATET= CALENDAR (DATE (2017, 1, 1), DATE (2017, 12, 31))

Answer 1

以下内容对我有用（并产生227,928行）：

DateTime = ADDCOLUMNS(
               CROSSJOIN(
                   CALENDAR(DATE(2000,1,1), DATE(2025,12,31)),
                   GENERATESERIES(0,23,1)
               ), 
               "DateTime", [Date] + TIME([Value], 0, 0)
           )

Answer 2

由于某些原因，数字换行被配置为默认值，但是我们仍然必须使用引号将数字换行，例如：

DateTime = 
ADDCOLUMNS (
    CROSSJOIN(
        CALENDAR(DATE("2000","1","1"),DATE("2025","12","31")),
        UNION (
            ROW ( "Time", TIME ( "1", "0", "0" ) ),
            ROW ( "Time", TIME ( "2", "0", "0" ) ),
            ROW ( "Time", TIME ( "3", "0", "0" ) ),
            ROW ( "Time", TIME ( "4", "0", "0" ) ),
            ROW ( "Time", TIME ( "5", "0", "0" ) ),
            ROW ( "Time", TIME ( "6", "0", "0" ) ),
            ROW ( "Time", TIME ( "7", "0", "0" ) ),
            ROW ( "Time", TIME ( "9", "0", "0" ) ),
            ROW ( "Time", TIME ( "10", "0", "0" ) ),
            ROW ( "Time", TIME ( "11", "0", "0" ) ),
            ROW ( "Time", TIME ( "12", "0", "0" ) ),
            ROW ( "Time", TIME ( "13", "0", "0" ) ),
            ROW ( "Time", TIME ( "14", "0", "0" ) ),
            ROW ( "Time", TIME ( "15", "0", "0" ) ),
            ROW ( "Time", TIME ( "16", "0", "0" ) ),
            ROW ( "Time", TIME ( "17", "0", "0" ) ),
            ROW ( "Time", TIME ( "18", "0", "0" ) ),
            ROW ( "Time", TIME ( "19", "0", "0" ) ),
            ROW ( "Time", TIME ( "20", "0", "0" ) ),
            ROW ( "Time", TIME ( "21", "0", "0" ) ),
            ROW ( "Time", TIME ( "22", "0", "0" ) ),
            ROW ( "Time", TIME ( "23", "0", "0" ) ),
            ROW ( "Time", TIME ( "24", "0", "0" ) )
        )
    ),
    "DateTime", [Date] + [Time],
    "Hour", HOUR ( [Time] )
)
