今天在做data migration时写了一个跨数据库查询的语句：
select d.ID as SGPID,'S' as SGPTYPE, 1 as UpUser, GETDATE() as UpDT, number
from [DataMigr_V33].[dbo].[_upd_dts_timedef1] c, [DataMigr_V4].[dbo].[adDTStore]d
where storenum<>0 and c.storenum = d.StrNumber
结果在运行时遇到这样一个问题，问题描述：
Cannot resolve the collation conflict between "Chinese_PRC_CI_AS" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.
到网上搜了一下，了解了问题产生的原因，原来是两个数据库的collation不一致导致的，DataMigr_V33用的是SQL_Latin1_General_CP1_CI_AS，而DataMigr_V4用的是Chinese_PRC_CI_AS，知道原因，解决起来就好办了。将查询语句改成如下：
select d.ID as SGPID,'S' as SGPTYPE, 1 as UpUser, GETDATE() as UpDT, number
from [DataMigr_V33].[dbo].[_upd_dts_timedef1] c, [DataMigr_V4].[dbo].[adDTStore]d
where storenum<>0 and c.storenum collate Chinese_PRC_CI_AS = d.StrNumber
问题就解决了。
这篇关于Sql server中Collation conflict问题的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
