Overloads

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

Counts the number of day boundaries crossed between the startDate and endDate. Corresponds to SQL Server's DATEDIFF(day, @startDate, @endDate).
DateDiffDay(DbFunctions, Nullable<DateTimeOffset>, Nullable<DateTimeOffset>)

Counts the number of day boundaries crossed between the startDate and endDate. Corresponds to SQL Server's DATEDIFF(day, @startDate, @endDate).
DateDiffDay(DbFunctions, Nullable<DateOnly>, Nullable<DateOnly>)

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

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

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

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

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

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