mssql和mysql区分大小写

Question

I should select all rows where a specific field starts with 'z' but not with 'Z' and the query should work both with mysql and mssql.

I can write the query separated for mssql and mysql, but I can't convert it to a unique query to work with both database.

I don't know if it is possible at all. Any idea?

Use proper collation . For example _BIN or Case Sensitive. You can find supported collations from following query.

SELECT * FROM sys.fn_helpcollations()   
WHERE name LIKE 'sql%latin%CS%' or name like '%BIN';  

and query like this

select * from dbo.Categories
where CategoryName collate SQL_Latin1_General_CP1_CS_AS like 'be%'
