Cannot resolve the collation conflict between “SQL_AltDiction_CP850_CI_AS” and “SQL_Latin1_General_CP1_CI_AS” in the equal to operation

Question

I have a piece of code in my stored procedure as below -

update tblexpwitretrocmdocs set sCheckedOut = A.sEditor, idone = 0 
from #tblDocs A
JOIN tblexpwitretroc         


        

Answer 1

Specify DATABASE_DEFAULT for the collation of all temp table string columns to use the current database default collation:

CREATE TABLE #tblDocs(
    iId INT IDENTITY (1,1),
    SID NVARCHAR(50) COLLATE DATABASE_DEFAULT,
    iDocumentTypeId INT,
    sType NVARCHAR(200) COLLATE DATABASE_DEFAULT,
    sEditor NVARCHAR(50) COLLATE DATABASE_DEFAULT
);

For columns that differ from the database default collation, specify the exact column collation instead of DATABASE_DEFAULT.
