使用间隔的 MS SQL Server 函数

Question

Hey there I have a Function trying to convert it from Oracle to MS SQL but I get incorrect syntax near '1' one line 7:

IF @nPaysQuarterly = 0 BEGIN
     -- If the base date is less than March 1st of the given year then the due date is for that year
     -- Else the due date is for the year plus 1
        If @dBaseDate < convert(DATETIME, '01-Mar-'+isnull(year(@dBaseDate), '')) BEGIN
            SET @dDueDate = convert(DATETIME, '01-Mar-'+isnull(year(@dBaseDate), ''));
        END
        ELSE BEGIN SET @dDueDate = convert(DATETIME, '01-Mar-'+isnull(year(@dBaseDate), '')) + interval '1' year;
        END 
    ELSE IF (@dBaseDate < @dAnnualDue1) BEGIN
          SET @dDueDate = @dAnnualDue1;
    ELSE IF (@dBaseDate < @dFirstQuarterDue) BEGIN
          SET @dDueDate = @dFirstQuarterDue;
    ELSE IF (@dBaseDate < @dSecondQuarterDue) BEGIN
          SET @dDueDate = @dSecondQuarterDue;
    ELSE IF (@dBaseDate < @dThirdQuarterDue) BEGIN
          SET @dDueDate = @dThirdQuarterDue;
    ELSE IF (@dBaseDate < @dAnnualDue) BEGIN
          SET @dDueDate = @dAnnualDue;
    END 

    RETURN AIP.GETNEXTBUSINESSDAY(@dDueDate) ;
END;

Anything wrong when adding 1 increment to the year ? Thank you.

i think this is the query you are looking for

IF (@nPaysQuarterly = 0 )
BEGIN
     -- If the base date is less than March 1st of the given year then the due date is for that year
     -- Else the due date is for the year plus 1
        If (@dBaseDate < convert(DATETIME, '01-Mar-'+isnull(year(@dBaseDate), '')))
            BEGIN
                SET @dDueDate = convert(DATETIME, '01-Mar-'+isnull(year(@dBaseDate), ''));
            END
        ELSE 
            BEGIN 
                SET @dDueDate = DATEADD(year,1,convert(DATETIME, '01-Mar-'+isnull(year(@dBaseDate), '')));
            END 

    IF (@dBaseDate < @dAnnualDue1) 
          SET @dDueDate = @dAnnualDue1;
    ELSE IF (@dBaseDate < @dFirstQuarterDue) 
          SET @dDueDate = @dFirstQuarterDue;
    ELSE IF (@dBaseDate < @dSecondQuarterDue) 
          SET @dDueDate = @dSecondQuarterDue;
    ELSE IF (@dBaseDate < @dThirdQuarterDue) 
          SET @dDueDate = @dThirdQuarterDue;
    ELSE IF (@dBaseDate < @dAnnualDue) 
          SET @dDueDate = @dAnnualDue;
    END 

    RETURN AIP.GETNEXTBUSINESSDAY(@dDueDate) ;
END;

you have to use DATEADD Function to add one year to your datetime value. another Issue is that you cannot start an IF Statement with an ELSE IF
