DateDiffYear(DbFunctions, DateTimeOffset, DateTimeOffset)

Counts the number of year boundaries crossed between the startDate and endDate. Corresponds to SQL Server's DATEDIFF(year, @startDate, @endDate).

DateDiffYear(DbFunctions, Nullable<DateOnly>, Nullable<DateOnly>)

Counts the number of year boundaries crossed between the startDate and endDate. Corresponds to SQL Server's DATEDIFF(year, @startDate, @endDate).

DateDiffYear(DbFunctions, Nullable<DateTime>, Nullable<DateTime>)

Counts the number of year boundaries crossed between startDate and endDate. Corresponds to SQL Server's DATEDIFF(year, @startDate, @endDate).
