How can one address the collation discrepancy that arises when the database and the table have different collations?

If you want to change the collation of the entire database, you can use the following command:

ALTER DATABASE YourDatabaseName

COLLATE NewCollationName

Replace "YourDatabaseName" with the name of your database and "NewCollationName" with the name of the collation you want to use.

Remember, changing the collation of a database will only affect the default collation of new tables and columns and won’t change the collation of existing tables and columns. You would need to change those individually if needed.

You can alter the collation of a specific column in a table using the ALTER TABLE statement. Here is a general example:

ALTER TABLE YourTableName

ALTER COLUMN YourColumnName

COLLATE NewCollationName

In this query, replace "YourTableName" with the name of your table, "YourColumnName" with the name of the column that has the collation issue, and "NewCollationName" with the name of the collation you want to use.

Please note that you should be careful when changing collation as it can affect your data and the performance of your queries. It’s recommended to back up your data before making such changes. Also, ensure that the new collation is compatible with your data.
