日期参数的存储过程调用出错

[影子传说_Hades]

刚刚开始搞，目前日期参数的存储过程调用出错，比如

CREATE PROCEDURE CountUserServDaysInMonth
    @UserId int = null,
    @ServiceId int = null,
    @RORDate datetime = null
AS
BEGIN
    PRINT 'RORDate is:'+CONVERT(datetime, @RORDate,101);
    DECLARE @ServiceStartTimeRec datetime,@ServiceEndTimeRec datetime,@recNum int=0,@sumDays int=0;
    SELECT @recNum = count(*) from UserServiceLog where UserId=@UserId and ServiceId=@ServiceId and @RORDate>= ServiceStartTime and @RORDate<= ServiceEndTime;
    PRINT 'record num is:'+CONVERT(varchar, @recNum);
    DECLARE cur_old_style CURSOR FOR select ServiceStartTime,ServiceEndTime from UserServiceLog where UserId=@UserId and ServiceId=@ServiceId and @RORDate>= ServiceStartTime and @RORDate<= ServiceEndTime;
    OPEN cur_old_style
    FETCH cur_old_style INTO @ServiceStartTimeRec,@ServiceEndTimeRec;
    WHILE (@@fetch_status=0)
    BEGIN
        --根据类型来判断增加还是减少，但目前缺乏类型标识
        DECLARE @i AS INT = 0;
        select @i=DATEDIFF(day,@ServiceStartTimeRec,@ServiceEndTimeRec);
        select @sumDays=@sumDays+@i;
        FETCH cur_old_style INTO @ServiceStartTimeRec,@ServiceEndTimeRec;
    END
    CLOSE cur_old_style;
    DEALLOCATE cur_old_style;
    PRINT 'Days in this month is:'+CONVERT(varchar, @sumDays);
END

但是调用会报错

EXEC CountUserServDaysInMonth @UserId=56038925,@ServiceId=1,@RORDate='2010-06-30 23:59:59.0';

报错
[FreeTDS][SQL Server]Conversion failed when converting date and/or time from character string.

EXEC CountUserServDaysInMonth @UserId=56038925,@ServiceId=1,@RORDate='2010-06-30 23:59:59';

'2010-06-30 23:59:59'

[影子传说_Hades]

EXEC CountUserServDaysInMonth @UserId=56038925,@ServiceId=1,@RORDate='2010-06-30 23:59:59'; 还是不行 [FreeTDS][SQL Server]Conversion failed when converting date and/or time from character string.

FreeTDS是什么接口，找相关资料看看日期类型如何表示的 如果调用支持参数的，用参数传入，而不要拼接sql语句

PRINT 'RORDate is:'+CONVERT(datetime, @RORDate,101); -> PRINT 'RORDate is:'+CONVERT(varchar, @RORDate,101);
