【问题描述】：

我正在尝试创建一个时间表以使过滤器范围介于 0 到 23 小时之间。这将是我的第一个问题，但由于语法错误，我什至无法创建任何表。（我不记得如何做到这一点）。我正在使用 Power BI Desktop，这是 DAX 计算表语法：

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] )
)

这给了我语法错误；（我也试过“，”）。我很确定我写错了一些简单的东西，错误/错误在哪里？谢谢

我尝试使用此代码（从 Internet 粘贴）但不起作用：

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

【问题讨论】：

当我将所有 ; 替换为 , 时，您的语法对我来说很好。
它对我不起作用，用逗号或分号。
尝试使用“输入数据”创建表，然后创建“新快速度量”以查看 Power BI 如何创建 DAX 公式语法。我很好奇有效措施的外观。

以下对我有用（并生成 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)
           )

这不行，我用逗号和分号试过：i.imgur.com/rvnA0Ub.png
使用逗号时出现同样的错误？它在我的程序中运行良好。
您是否在regional settings 中定义了不同的列表分隔符？
嗯，区域设置“Locale for import”配置为“Spanish”……是这个意思吗？
我的意思是，在我链接的帖子的最后一张图片中，“列表分隔符”显示的是什么字符？

【解决方案2】：

由于某种原因，数字换行被配置为默认值，但我们仍然必须使用引号来换行，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] )
)
