This can be useful if certain columns need to be case-insensitive, while the rest of the database needs to be case-sensitive. When the default semantics are not suitable, such as when the members must be compared out of order, or must use a comparison that's different from their natural comparison, then the programmer can write operator<=> and let the compiler generate the appropriate two-way comparison operators. In general, the issue of uppercase/lowercase comparisons and case-insensitive matching is a bit hairy, and also locale dependent (Turkish dotted and dotless i being the usual example). More info about Internet Explorer and Microsoft Edge, Microsoft.Data.Sqlite documentation on collations. WebHow to do a case insensitive string comparison in C#?

More importantly, applying a collation would in most cases prevent index usage, significantly impacting performance for a very basic and commonly-used .NET construct. So far it has compiled after this change. This can be accomplished by explicitly specifying a collation within the query itself: This generates a COLLATE clause in the SQL query, which applies a case-sensitive collation regardless of the collation defined at the column or database level: Indexes are one of the most important factors in database performance - a query that runs efficiently with an index can grind to a halt without that index.
