| Hi friends,I have some queries on reagding collations. Can anyone guide me in the right direction??1.We are in process in building new SQL Servers to host multiple application Databases. Do you recommend that a SQL Server of a collation only hosts application DBs of the same collation? 2.Would like to know what is the impact if I communicate between two sql server having different system/application database collation settings. 3.Is there any harm, if I have system database collation as different and application database collation different? 4.What is the difference between Latin1_General_CI_AS, SQLSortOrder=0 SQL_Latin1_General_CP1_CI_AS, SQLSortOrder=525. What kind of impact in sql quries and distributed quries will have with database with different collation settings.Any thoughts or links would be greatly appreciated.Thanks in Advance. |

| 1. Not necessarily, it depends what you want to do. Remember that Db's inherit sql server's default location if you do not specify a collation for the dbs. Why are you thinking of having multiple collations? Is there a business need for that?2. There will be impact specifically on your queries that might join tables/views between disparate collations3. It depends what you do. Again why do you want so many different collations = maintenance nightmare. and make sure to consult with your BI and SQL developers.4. Read BOL5. The impact will be nightmare on elm street. you will have to re-collate your queries everywhere.from maintenance pov imo very bad design approach.If you don't have the passion to help people, you have no passion |

| One doubt,Does the SQLSortOrder is tied up with the collation name or the code page????I have created a database with collation "SQL_Latin1_General_CP1_CI_AS" and when i say sp_helpdb 'db1'Collation=SQL_Latin1_General_CP1_CI_AS, SQLSortOrder=52Similary i have created one more database "db2" with collation as "Latin1_General_CI_AS" and when i say sp_helpdb 'db2' Collation=Latin1_General_CI_AS, SQLSortOrder=0Also, i have executed the following queries select * from fn_helpcollations() where name = 'SQL_Latin1_General_CP1_CI_AS'/*name descriptionSQL_Latin1_General_CP1_CI_AS Latin1-General, case-insensitive, accent-sensitive, kanatype-insensitive, width-insensitive for Unicode Data, SQL Server Sort Order 52 on Code Page 1252 for non-Unicode Data*/select * from fn_helpcollations() where name = 'Latin1_General_CI_AS'/*Latin1_General_CI_AS Latin1-General, case-insensitive, accent-sensitive, kanatype-insensitive, width-insensitive*/Now my question is Does the SQLSortOrder is tied up with the collation name or the code page????Am slightly confused.Can anyone help me out with some easy explaination???Thanks in Advance. |
