Trigger To Calculate Age From Date Of Birth

Dec 12, 2003

Here's the problem. I want to insert age in years to a table of children, using a MS SQL trigger to calculate age from Date of Birth (DOB). DOB format is mm/dd/yyyy. The DOB input comes from an ASP Insert statement. I've tried to use DateDiff and a user-defined function to calculate age without any success. Also the trigger needs to account for children of less than 1 year old, could be a 0. Age is integer in the children table. Any help is greatly appreciated. The sooner the better. Even a kick start is better than nothing.

Date Of Birth Conversion

Apr 18, 2000

Hello
Can someone help please?
I'm using SQL Server 7 and trying to update a table containing over 250,000 records. I have a character(8) (CHARDOB) field representing dates of birth in the form YYYYMMDD and would like to update my datetime field (DOB) using a simple update command like:-

UPDATE MyTable SET DOB = RIGHT(CHARDOB, 2) + '/' + SUBSTRING(CHARDOB,
5, 2) + '/' + LEFT(CHARDOB, 4)

but get the message:-

Server: Msg 242, Level 16, State 3, Line 1
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
The statement has been terminated.

The strange thing is that this works on a small dataset but crashes and burns on larger ones. I have tried different CAST and CONVERT options to transform the data into the correct format. I have tried a stored procedure, DTS transformations and execute SQL task in my DTS package without success.

Any help will be appreciated.

Formatting For A Birth Date Field??

Sep 16, 2006

Hello, I'm new to SQL Server, working for a non-profit computerizing alot of its data.I imported a table of people's names, birth dates, etc. into SS2005from Access, and the birth_date was imported as an Access date/timefield, giving it the datetime datatype in SQL.The column values look like:10/14/1964 12:00:00 AMWhere and how do I learn to specify that all fields like this should bein ISO format of yyyy-mm-dd??Do I have to create a new column and put all the dates into it??Should I just convert the data in queries/views??Use a constraint to format the data??I can redo the Access table if necessary, it is only 300-some rows.I tried BOL but it was not helpful...The end users will likely enter mm/dd/yy or mm/dd/yyyy and it will haveto be stored properly in the database table as column/fieldbirth_date...Thank you, Tom

Let's say the child records have a field with a value in the range 1-9

Now I want to find the maximum value in the child records.

Power Pivot :: Calculate Sum Of Actual Sales Until Date And Forecast Sales After A Date?

Sep 30, 2015

I want to calculate the sum of actual sales until a date and forecast sales after a date.I am not sure what the best approach to this problem is, but I have tried my best with the following approach. Any better ways to solve this (using DAX).

I have created a parameter table that offers the last date of each month as possible choices to the user. I have tried to create a measure that sums actual sales up until this date.

SalesQuantityActual:=IF(HASONEVALUE(parLastActualMonth[Date]);CALCULATE(factSalesActual[Quantity];factSalesActual[Date]<=VALUES(parLastActualMonth[Date]));BLANK())

Unfortunately the measure above does not work.

In addition to the parameter table, I also have a normal date table.

I want to get the number of days pending for a perticular column. I want the out put as a integer value.

This is what I used for my calculated field.

When I use following query, I get no error message. but still no data in the column too.

=DATEDIFF("d", Fields!SubmittedDate.Value, "GETDATE()" )

Can anyone tell me why is that?

I need to calculate the number of working days from a date backwards. For example 2 working days before Thursday would be the Tuesday (as a basic example)

I use the following code and a Calendar table to calculate the working days from a date but can anyone help with reworking this query to do the reverse

SELECT @WorkingDate=dt
FROM tblCalendar AS c
WHERE (@WorkingDays =
(SELECT COUNT(*) AS Expr1
FROM tblCalendar AS c2
WHERE (dt >= @StartDate) AND (dt <= c.dt) AND (IsWeekday = 1) AND (IsHoliday = 0))) AND (IsWeekday = 1)
AND (IsHoliday = 0)

-- Return the result of the function
RETURN convert(varchar(12),@WorkingDate,106)

Hope someone can help

Thanks
