optimize select statement

Hello,

How can I optimize for not use not in :
INSERT INTO [anomalies_ods]( [ROWID],[ServeurSource],[DbSource], [SchSource], [ArticleSource])
select ROWID   , '''+@SrvSource+''', '''+@DbSource+''' , '''+@SchSource+''', '''+@ArticleSource+'''
from ['+@SrvSource + '].['+ @DbSource + '].['+ @SchSource + '].['+ @ArticleSource + ']s
where s.[ROWID] not in (select [ZROWID_0]from ['+@SrvAbonne + '].['+ @DbCible + '].['+ @SchCible + '].['+ @ArticleCible + ']
where [ZORIDOS_0] = '''+@Schsource+''')'

Thanks

Regards

bibi

This is not that clear since you have submit a code from your applciation. Can you just put your SQL String here so it is more readable and table names are visible.

In most cases NOT IN can be replaced with a simple INNER JOIN. I would be able to help you if you can publish the SQL String

You can use exists keyword in place of Not IN

from ['+@SrvSource + '].['+ @DbSource + '].['+ @SchSource + '].['+ @ArticleSource + ']s
where not exists (select 1 from ['+@SrvAbonne + '].['+ @DbCible + '].['+ @SchCible + '].['+ @ArticleCible + '] a
where a.[ZORIDOS_0] = '''+@Schsource+''' and  s.[ROWID] = a.[ZROWID_0])'
