寻找能够帮助更快地编写脚本更新语句的软件

Question

我有很多平凡的更新语句，我必须通过PLSQL和MSSQL，它需要大量的编辑。我通常会将数据拉入excel而不是在notepad ++中重新格式化。这是非常耗时的，我想知道是否有任何解决方案吗？

UPDATE ATGSITES SET IPADDRESS = 'xxx' WHERE OWNSITEID = '270789'
UPDATE ATGSITES SET IPADDRESS = '1yyy' WHERE OWNSITEID = '270506'
UPDATE ATGSITES SET IPADDRESS = '158568' WHERE OWNSITEID = '27745'

X（35353）更新声明

Answer 1

也许您可以创建更新表并执行单个连接

UPDATE ATGSITES SET IPADDRESS = B.IPADDRESS
 From  ATGSITES A
 Join  NewTable B on A.OWNSITEID = B.OWNSITEID 

NewTable的结构为OWNSITEID和IPADDRESS

我还会在OWNSITEID

上添加一个索引

Answer 2

在Ms Sql Server中

将数据保存在以逗号（如该格式）分隔的CSV文本文件中

IPADDRESS   , OWNSITEID
xxx      ,270789
1yyy     ,270506
158568   ,27745
......
...........

假设要更新的表名为：users_ip

运行以下脚本以从文本文件

更新表

-- update table users_ip from csv file delimited wth , and first row is  header

-- create temp table for loading the text file
CREATE  TABLE #tmp_x (IPADDRESS nvarchar (10),OWNSITEID nvarchar(10))
go

-- import the csv file
BULK INSERT #tmp_x
FROM 'c:\temp\data.txt' --CSV file with header delimited by ,
WITH ( FIELDTERMINATOR =',',rowterminator = '\n',FIRSTROW = 2 )
go

update u
set u.IPADDRESS = t.IPADDRESS
from users_ip u
join #tmp_x t on  t.OWNSITEID = u.OWNSITEID

//drop the temp table
drop table #tmp_x
