从AX2012系统批量生成CSV格式数据

以CSV格式导出数据，大家应该都很熟悉，最近遇到导出CSV格式的数据格式，这里分享下。导出CSV格式的数据，我这里总结了三种：

1.以逗号分隔的csv文件（字段内容无双引号，不推荐用，若导入数据值中有逗号，容易错列）

Public boolean AX3PLExport_Cust_Bth()
{
    TextBuffer              textBuffer;
    str                     FileName,FilePath, File;
    CustTable               custTable;
    FileIOPermission        fioPermission;
    int                     Lines;
    str                     custAccount;
    #File
    ;
	
    FilePath    = "C:Test"	;
    Filename    = Test.csv;
    File  = FilePath + '\\' + Filename;

    try
    {
        fioPermission = new FileIOPermission(File ,"RW");
        fioPermission.assert();

        textBuffer  = new TextBuffer();
        textBuffer.appendText("CustAccount,");
        textBuffer.appendText("CustName,");
        textBuffer.appendText("CustAddress");  
        textBuffer.appendText("
");
		
        ttsBegin;

        while select  forupdate custTable
            index hint AccountIdx
            where custTable.Transferred == NoYes::No
              &&  custTable.AccountNum
        {
            textBuffer.appendText(custTable.AccountNum); //textBuffer.appendText('"' + custTable.AccountNum + '",'); 可手动加双引号
            textBuffer.appendText(strReplace(custTable.name(), "
", "")); 
            textBuffer.appendText(strReplace(custTable.address(), "
", "")); 
            textBuffer.appendText("
");
        }
		
        ttsCommit;
        Lines = textBuffer.numLines();
        try 
        {               
            if (textBuffer.toFile(File,FileEncoding::UTF8))  
                info( strfmt("File Generated as %1.total insert %2 Lines",File,Lines));  
        }  
        catch ( Exception::Error )  
        {  
            error (strFmt("No Data export for MainProducts",File));  
        }    
        CodeAccessPermission::revertAssert();
    }
    catch(Exception::Deadlock)
    {
        retry;
    }
    if (Lines > 0)
    {
        return true;
    }
    else
    {
        return False;
    }
}

导出格式如下：若需要导出待双引号的csv格式，可参考代码注释的地方，强行加入双引号，但这样就比较繁琐了　　

2. 导出双加号的csv文件，UTF-8格式（带BOM的的UTF-8）

Public boolean AX3PLExport_CustCSV_Bth()
{
    CommaTextIo             commaTextIo;
    container               line;
    str                     FileName,FilePath, File;
    CustTable               custTable;
    FileIOPermission        fioPermission;
    int                     Lines;
    str                     custAccount;
    #File
    ;

    FilePath    = "C:Test" ;
    Filename    = "Test.csv";
    File  = FilePath + '\\' + Filename;
	
    try
    {
        fioPermission = new FileIOPermission(File ,"RW");
        fioPermission.assert();

        commaTextIo  = new CommaTextIo(File, #io_write, 65001);//65001代表UTF-8的编码格式,默认是带Bom的UTF-8

        if (!file || commaTextIo.status() != IO_Status::Ok)
        {
            throw error("File cannot be opened.");
        }

        ttsBegin;

        while select forUpdate custTable
            where  custTable.Transferred == NoYes::No
             &&    custTable.AccountNum
        {
             line = [custTable.AccountNum,
                    strReplace(custTable.name(), "
", ""),
                    strReplace(custTable.address(), "
", "")];

            commaTextIo.writeExp(line);
            Lines++;
        }

        ttsCommit;

        try 
        {               
            if (File)  
                info( strfmt("File Generated as %1.total insert %2 Lines",File,Lines));  
        }  
        catch ( Exception::Error )  
        {  
            error (strFmt("No Data export for MainProducts",File));  
        }         
        CodeAccessPermission::revertAssert();
    }
    catch(Exception::Deadlock)
    {
        retry;
    }
}

导出的格式如下。这样的格式大多数情况下就满足了我们的需求。但假如是导出的接口数据，某些奇葩系统没法解析，只认不带BOM的UTF-8格式就不好用了。

 3. 导出双加号的csv文件，UTF-8格式（不带BOM的的UTF-8，单独运行没有问题，当批处理跑时，就会报当前文件被另一进程使用）

Public boolean AX3PLExport_CustCSV_Bth()
{
    CommaTextIo             commaTextIo;
    container               line;
    str                     FileName,FilePath, File;
    CustTable               custTable;
    FileIOPermission        fioPermission;
    int                     Lines;
    str                     custAccount;
    System.Text.Encoding    encoding = new System.Text.UTF8Encoding(false);
    #File
    ;

    FilePath    = "C:Test" ;
    Filename    = "Test.csv";
    File  = FilePath + '\\' + Filename;

    try
    {
        fioPermission = new FileIOPermission(File ,#io_write);
        fioPermission.assert();
        commaTextIo  = new CommaTextIo(File, #io_write, 65001);
        if (!file || commaTextIo.status() != IO_Status::Ok)
        {
            throw error("File cannot be opened.");
        }
		
        ttsBegin;
        while select forUpdate custTable
            where  custTable.Transferred == NoYes::No
             &&    custTable.AccountNum
        {
             line = [custTable.AccountNum,
                    strReplace(custTable.name(), "
", ""),
                    strReplace(custTable.address(), "
", "")];

            commaTextIo.writeExp(line);
            Lines++;
        }        
        CodeAccessPermission::revertAssert();
        commaTextIo = null;
        ttsCommit;
        
        new InteropPermission(InteropKind::ClrInterop).assert();
        System.IO.File::WriteAllText(File, System.IO.File::ReadAllText(File), encoding);
        CodeAccessPermission::revertAssert();

        try 
        {               
            if (File)  
                info( strfmt("File Generated as %1.total insert %2 Lines",File,Lines));  
        }  
        catch ( Exception::Error )  
        {  
            error (strFmt("No Data export for MainProducts",File));  
        }  
       
    }
    catch(Exception::Deadlock)
    {
        retry;
    }
}

结果如下：

4. 导出带双加号的csv文件，UTF-8无Bom格式，可批处理使用。

private void ExportCust()
{
    TextBuffer              textBuffer;
    str                     FileName,FilePath, File;
    CustTable               custTable;
    FileIOPermission        fioPermission;
    int                     Lines;
    str                     custAccount;
    str                     data;
    System.Text.Encoding    encoding = new System.Text.UTF8Encoding(false);
    #File
    ;

    File  = @'C:Tmpaccounts.csv';

    try
    {
        fioPermission = new FileIOPermission(File ,"RW");
        fioPermission.assert();

        textBuffer  = new TextBuffer();

        while select firstOnly  custTable
        {
            textBuffer.appendText('"' + custTable.AccountNum + '",');
            textBuffer.appendText('"' + strReplace(custTable.name(), "
", "") + '",');
            textBuffer.appendText('"' + strReplace(custTable.address(), "
", "") + '"');
            textBuffer.appendText("
");
        }

        Lines = textBuffer.numLines();
        info(textBuffer.getText());
        data = textBuffer.getText();
        textBuffer.toFile(File,FileEncoding::UTF8);

        CodeAccessPermission::revertAssert();

        try
        {
            new InteropPermission(InteropKind::ClrInterop).assert();
            System.IO.File::WriteAllText(File, data, encoding);
            CodeAccessPermission::revertAssert();

            if (File)
                info( strfmt("File Generated as %1.total insert %2 Lines",File,Lines));

        }
        catch ( Exception::Error )
        {
            error (strFmt("No Data export for MainProducts",File));
        }
    }
    catch(Exception::Deadlock)
    {
        retry;
    }

}
