Question

我一直在努力将以下t sql任务转换为自动ssis包。我尝试使用for loop conntainer实现，但在创建循环逻辑时，我正在坚持下去。我真的很感激有人可以用逻辑来帮助我

这是t-sql代码

-- SCRIPT TO BULK IMPORT MATERNAL HLA & INSERT CORD NIMA


IF OBJECT_ID('tempdb..#maternal_hla_from_solar') IS NOT NULL
BEGIN
      drop table #maternal_hla_from_solar
END

CREATE TABLE #maternal_hla_from_solar(
      [donor_id] [int] NOT NULL,
      [antigen_id] [int] NOT NULL
)

-- bulk upload maternal HLA from file
BULK
INSERT #maternal_hla_from_solar
FROM 'C:\Users\zabeenp\Documents\SQL\populate_db\data\20111212_maternal_hla.txt'
WITH
(
FIRSTROW = 2,
MAXERRORS = 0,
FIELDTERMINATOR = '\t',
ROWTERMINATOR = '\n'
)

-- declare variables
DECLARE @donor_id int
DECLARE @maternal_hla varchar(5000)
DECLARE @definitive_type_date date = GETDATE()
DECLARE @modified_on datetime2(7) = GETDATE()

-- Cursor to process each row from #maternal_hla_from_solar
DECLARE c_insertCordNima CURSOR FAST_FORWARD
FOR select DISTINCT donor_id from #maternal_hla_from_solar -- important to use DISTINCT here
OPEN c_insertCordNima
FETCH NEXT FROM c_insertCordNima INTO @donor_id
WHILE @@FETCH_STATUS = 0
BEGIN
      SET @maternal_hla = ''  -- important to wipe string each time

      -- concatenare maternal antigen_ids into one string
      SELECT @maternal_hla = COALESCE(@maternal_hla + ',', '') + CONVERT(VARCHAR(10),antigen_id)
      FROM #maternal_hla_from_solar
      where donor_id = @donor_id

      -- remove first comma
      SET @maternal_hla = (select right(@maternal_hla,len(@maternal_hla)-1))

      -- exec insertCordNIMA SP
      EXECUTE insertCordNIMA
         @donor_id
        ,@maternal_hla
        ,@definitive_type_date
        ,@modified_on

      FETCH NEXT FROM c_insertCordNima INTO @donor_id
END
CLOSE c_insertCordNima
DEALLOCATE c_insertCordNima

也许尝试使用Recursive CTE重写光标？
