问题描述
我有一个 6.00 GB 的 .txt
文件.它是一个制表符分隔的文件,所以当我尝试将它加载到 SQL Server 时,列分隔符是制表符.
I have a .txt
file which is 6.00 GB. It is a tab-delimited file so when I try to load it into SQL Server, the column delimiter is tab.
我需要将该 .txt
文件加载到数据库中,但我不需要 6.00 Gb 文件中的所有行.我需要能够使用像
I need to load that .txt
file into the database, but I don't need all the rows from the 6.00 Gb file. I need to be able to use a condition like
select *
into <my table>
where column5 in ('ab, 'cd')
但这是一个文本文件,无法在该条件下将其加载到数据库中.
but this is a text file and am not able to load it into db with that condition.
谁能帮我解决这个问题?
Can anyone help me with this?
推荐答案
您是否尝试过 BULK INSERT 命令?看看这个解决方案:
Have you tried with BULK INSERT command? Take a look at this solution:
--Create temporary table
CREATE TABLE #BulkTemporary
(
Id int,
Value varchar(10)
)
--BULK INSERT has no WHERE clause
BULK INSERT #BulkTemporary FROM 'D:TempFile.txt'
WITH (FIELDTERMINATOR = ' ', ROWTERMINATOR = '
')
--Filter results
SELECT * INTO MyTable FROM #BulkTemporary WHERE Value IN ('Row2', 'Row3')
--Drop temporary table
DROP TABLE #BulkTemporary
希望这会有所帮助.
