Question

我有一个SQL表作为Source，我想使用SSIS将它的内容导出到一个Flat文件。

简化示例：

$(function() {
    $(".AddItem").click(function() {
  $(this).closest('table').find('tr:last').prev().after('<tr><td><select type="select" class="custom-select custom-select_gray" data-toggle="dropdown" id="dropdownMenuAdded" aria-haspopup="true" aria-expanded="true" style="font-family: \'Work Sans\', Tahoma, Geneva, sans-serif;font-size:10px;color:#606060;text-align:center;width:100px;height:25px;"><option label="Event">Event</option></select></td></tr>');
  addOptions();
        return false;
    });
});
function addOptions(){
var events = [[ "Event 1", "10.04"], [ "Event 2", "30.04"]];
var selId = "dropdownMenuAdded";


initDropdownList(selId, events);
}
function initDropdownList( id, eventEls ) {
    var select, i, option;

    select = document.getElementById( id );
    for ( i = 0; i < eventEls.length; i++ ) {
        option = document.createElement( 'option' );
        /* alert("eventEls.length: " + eventEls.length);
        alert("eventEls[i]: " + eventEls[i][0] + " " + eventEls[i][1]);*/
        option.value = option.text = eventEls[i][0] + " " + eventEls[i][1];
        select.add( option );
    }
    select.id = "dropdownMenu1";
}

$(function() {
    $(".AddOption").click(function() {


});
});

问题是描述可能很长，我们不希望在Source: Notes table (CreatedBy, Description, CreatedOn) The Description field is nText. Destination: Flat file - Fixed length CreatedBy(0-50) Description (51-250) CreatedOn (251-270)字符之后将其截断。它应该换行到下一行。

我找不到使用SSIS的方法。

非常感谢您的帮助。

我希望实现如下布局：

Hadi的答案允许将长字符串分成几部分，但仍然无法解决布局问题。

您必须按照以下步骤操作：

在DataFlow Task和OLEDB Source

Flat File Destination

在Script Component标记Description列作为输入，将OutDescription列添加为类型DT_WSTR和长度200

在Script窗口中输入以下代码（内部Input0_RowProcessing方法：

If Not Row.Description_IsNull AndAlso 
   Not String.IsNullOrEmpty(Row.Description.Trim) Then

       If Row.Description.Trim.Length > 200 Then

            Dim LongString As String = Row.Description.Trim

            Dim longlist As New System.Collections.Generic.List(Of String)

            Dim idx As Integer = 0

            While idx <= LongString.Length

                If LongString.Length < idx + 200 Then
                    longlist.Add(LongString.Substring(idx))
                Else
                    longlist.Add(LongString.Substring(idx, 200))
                End If



                idx += 200

            End While

            Row.OutDescription = String.Join(vbNewLine & "".PadLeft(50,CChar(" ")), longlist)

       Else

           Row.OutDescription = Row.Description

        End If

Else


    Row.OutDescription_IsNull = True


End IF

在Flat File Destination地图OutDesciption列而不是Description列

SSIS平面文件目标导出多行列
