请问你能帮我理解输出到输出流 4GL 和输出流之间的区别,还有什么是流？,进度文档页面没有多大帮助.

非常感谢你.

何我为可以接受三个输入参数的程序编写代码:x,y和要写入的文件名？

我应该能够像这样调用程序:运行prog.p(输入"1",输入5,输入"filename1.csv").

到目前为止,我已经编写了下面的代码,不知道如何解决它.

OUTPUT TO xxxxxx\filename1.csv". 

DEFINE VARIABLE Profit AS DECIMAL  FORMAT "->>,>>9.99":U INITIAL 0 NO-UNDO.

EXPORT DELIMITER "," "Amount" "Customer Number" "Invoice Date" "Invoice Number" "Total_Paid" "Profit".

FOR EACH Invoice  WHERE Invoice.Ship-charge > 5.00
                  AND   Invoice.Total-Paid > 0.01
                  AND   Invoice.Invoice-Date GE 01/31/93 /* this is between  also can use < >*/
                  AND   Invoice.Invoice-Date LE TODAY NO-LOCK:

    Profit = (Invoice.Invoice-Num / Invoice.Total-Paid) * 100.

EXPORT DELIMITER "," Amount Cust-Num Invoice-Date Invoice-Num  Total-Paid Profit. 
END.

OUTPUT CLOSE.

谢谢.

如何在 SQL 中获取上一年的最后日期，例如 20211231？

或者甚至获取列表中之前的最后日期

20211231
20221231
20191231
20181231

我想在 SSRS 中使用该信息。

谢谢。
