Оптимизация запросов для пейджинга

Question

У меня есть следующая хранимая процедура, и она работает нормально. Но я хочу реализовать внутренний пейджинг в операторах select, прежде чем переходить к внешнему пейджингу для табличного параметра, чтобы повысить производительность запросов в случае больших данных. Пожалуйста, объясните мне, как это сделать. Или есть какой-то другой подход для написания этой хранимой процедуры, который будет более эффективным.

Create PROCEDURE [dbo].[GetEventsAndNotesByAccountId]
    @AccountId INT ,
    @EventType VARCHAR(50) ,
    @IsLinkedAccountsNotes BIT,
    @ExcludedEvents VARCHAR(MAX) ,
    @Page INT ,
    @PageSize INT ,
    @SortOrderASC BIT = 1

    DECLARE @ExcludedEventsTable TABLE ( EventType VARCHAR(50) )

    DECLARE @input VARCHAR(MAX) = @ExcludedEvents,

    IF ( @input IS NOT NULL )
        BEGIN 
            SET @ind = CHARINDEX(',', @input) 
            WHILE @ind > 0
                BEGIN 
                    SET @str = SUBSTRING(@input, 1, @ind - 1)
