大家好，因为我已经在这里发布了：

我在执行我的 SSIS 包时遇到了一些问题，实际上它们需要大量时间。由于很多限制，我正在尝试一对一解决！我从查询开始，提取 720 000 行需要三个多小时：

Select 
    --11 fields from tbl1
    Tbl1.field1 As field1,
    ….
    .
    .
    Tbl1.field11 As field11,

    CASE WHEN (dbo.tbl1.field11 = 'J') 
                          THEN N'Batch' ELSE dbo.tbl1.field11 END AS creation_oprid, CONVERT(date, tbl1.date1) 
                          AS creation_date, CONVERT(date, tbl1.date2) AS update_date, 
                          CASE WHEN (dbo.tbl1.field12 = 'J')
