Cannot resolve the collation conflict between “SQL_Latin1_General_CP1_CI_AS” and “Latin1_General_CI_AS” in the UNION operation

Question

I have to join 2 views and create table which populates dates from the view.

But I am getting this error:

Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS" in the UNION operation.

CREATE VIEW [dbo].[Destinations_1415_1516_Union]
AS
SELECT *
FROM
[dbo].[Destinations_1415] 
UNION
SELECT *
FROM
[dbo].[Destinations_1516] 
GO

Please suggest how to resolve this

Answer 1

Hi agreeing with what people above have said, if you do the following:

SELECT ColumnA COLLATE DATABASE_DEFAULT
    ,ColumnB COLLATE DATABASE_DEFAULT
    --,... (rest of Columns)
FROM [dbo].[Destinations_1415] 
UNION 
SELECT ColumnA COLLATE DATABASE_DEFAULT
    ,ColumnB COLLATE DATABASE_DEFAULT
    --,... (rest of Columns)
FROM [dbo].[Destinations_1516]

This should get rid of your problem, you just need to identify what column it is that has the collation error.
