无法解决 Join 语句中的排序规则冲突

Question

I have the following join, that spits out this error

"Cannot resolve the collation conflict between "Latin1_General_BIN" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.

I tried editing by adding:

ns.dw_item_location COLLATE Latin1_General_BIN AS dil

as well as

ns.dw_item_location COLLATE SQL_Latin1_General_CP1_CI_AS AS dil

and didn't resolve this error. I also tried

IR.ItemNo COLLATE_Latin1_General_BIN as ItemNo

earlier in the SQL statement and still no resolution.

left join ns.dw_item_location dil on dil.znumber = IR.ItemNo

The expected outcome should resolve this error by correcting the correlation

Answer 1

You are putting the collate in the wrong place. You should put it immediately after the column name inside the equals clause

left join ns.dw_item_location dil on dil.znumber collate database_default = IR.ItemNo

You will notice I used database_default meaning "whatever the current database uses" which is usually simpler if you have a conflict between "this" database and "another" database.
