Question

有没有办法可以遍历我的SQL Server表并写出一个文本文件删除文件需要多长时间才能说每10,000行？

DELETE FROM ORDERS o
INNER JOIN CUSTOMER c
    ON o.CustomerID = c.CustomerID
WHERE ActiveDt < '03/03/2001'    

DELETE FROM CUSTOMER
WHERE ActiveDt < '03/03/2001'

Answer 1

DECLARE  @TS AS datetime;
DECLARE @CNT int;

lab:
SET @TS = getdate();
;WITH CTE AS (SELECT TOP 10000 * from CustTable)
    DELETE CTE ;

SET @CNT = @@rowcount;

PRINT DATEDIFF(millisecond, @TS, getdate());  --write away somewhere if required 

If @CNT > 0
    GOTO lab

您可以使用spWriteStringToFile将数据推送到文本文件
