dts导入的问题。
导入一个5G左右的文本文件的数据，中途出错了。错误信息我没有几下来。
到数据库一看，数据没有导入，可是磁盘空间被占了2G多。
怎么回事？
2G是日志文件吧~
这里有一个缩小日志文件的办法.
SET NOCOUNT ON
DECLARE @LogicalFileName sysname,
@MaxMinutes INT,
@NewSize INT
USE ttdatabase -- 要操作的数据库名
SELECT @LogicalFileName = ttdatabase_log, -- 日志文件名
@MaxMinutes = 10, -- Limit on time allowed to wrap log.
@NewSize = 100 -- 你想设定的日志文件的大小(M)
-- Setup / initialize
DECLARE @OriginalSize int
SELECT @OriginalSize = size
FROM sysfiles
WHERE name = @LogicalFileName
SELECT Original Size of + db_name() + LOG is +
CONVERT(VARCHAR(30),@OriginalSize) + 8K pages or +
CONVERT(VARCHAR(30),(@OriginalSize*8/1024)) + MB
FROM sysfiles
WHERE name = @LogicalFileName
CREATE TABLE DummyTrans
(DummyColumn char (8000) not null)
DECLARE @Counter INT,
@StartTime DATETIME,
@TruncLog VARCHAR(255)
SELECT @StartTime = GETDATE(),
@TruncLog = BACKUP LOG + db_name() + WITH TRUNCATE_ONLY
DBCC SHRINKFILE (@LogicalFileName, @NewSize)
EXEC (@TruncLog)
-- Wrap the log if necessary.
WHILE @MaxMinutes > DATEDIFF (mi, @StartTime, GETDATE()) -- time has not expired
AND @OriginalSize = (SELECT size FROM sysfiles WHERE name = @LogicalFileName)
AND (@OriginalSize * 8 /1024) > @NewSize
BEGIN -- Outer loop.
SELECT @Counter = 0
WHILE ((@Counter > @OriginalSize / 16) AND (@Counter > 50000))
BEGIN -- update
INSERT DummyTrans VALUES (Fill Log)
DELETE DummyTrans
SELECT @Counter = @Counter + 1
END
EXEC (@TruncLog)
END
SELECT Final Size of + db_name() + LOG is +
CONVERT(VARCHAR(30),size) + 8K pages or +
CONVERT(VARCHAR(30),(size*8/1024)) + MB
FROM sysfiles
WHERE name = @LogicalFileName
DROP TABLE DummyTrans
SET NOCOUNT OFF
5G的文本还真没见过
可以先分离然后附加数据库
