从进度数据创建CSV文件

Question

我想导出一些数据库记录来创建一个CSV文件。下面的代码创建CSV文件：

方法私人无效GenerateCSV（）：

OUTPUT TO VALUE ("c:users\mark\test.csv"). 

    FOR EACH a-table WHERE a-table.id = 1: 

      EXPORT DELIMITER ',' a-table.name a-table.cost a-table.unit. 

    END. 

    OS-COMMAND NO-WAIT "c:\users\mark\test.csv". 

End方法。

这不工作，并创建一个csv文件与所有需要的记录，但是我想知道如何我可以把标题放入csv文件，因此每个我想让他们说[名称] [成本] [单位]。这是如此，当csv文件在Excel中打开时，列有标题。

有没有人有任何想法如何做到这一点？

Answer 1

OUTPUT TO VALUE ("c:users\mark\test.csv"). 

export delimiter "," "Head1" "Head2" "Head3". 

FOR EACH a-table WHERE a-table.id = 1: 
... 

Answer 2

下面是一些代码提取三个表3个不同的CSV文件和设置他们写得太根据您是否在Windows或UNIX上运行的路径。文件名也是在运行时创建的。

头记录与逗号分隔的条目（使用数据库字段插件形成和排除的表名则只是:-)

之间

我也有，可以用来写出来的任何错误日志文件输入分隔符，如果需要的话。

如果出现错误，文件将在finally块中关闭。
