Get Birthdate

Apr 06, 2012 10:15 AM|LINK
The table has first and last names but no ID.

It has a birthdate column which is null for all but it has an age column. How can I update the birthdate? This returns a syntax error:
```
update dbo.Sheet1$BikeSebring24Hours021912_1
set dob  =   CAST(CAST( DATEPART(yyyy, GETDATE() ) - sb.age  FROM Sheet1$BikeSebring24Hours021912_1 sb  WHERE lname = sb.lname and fname = sb.fname)  AS VARCHAR(4))  + '-01-01' as datetime)
```

I believe with only age you would not be able to find birthdate. you would only be able to find the year but not exact date.

select dob=DATEADD(yy,-24,'2012-11-10')

or

select dob=DATEADD(yy,-age,'2012-11-10') from ages

see -ve sign before age column

Sorry, I did not explain. for our purposes everyones birthday is January 1, so all I need to do is get the year and add it to 1/1.

Try something like that:
```
update dbo.Sheet1$BikeSebring24Hours021912_1
set dob = CAST( CAST( DATEPART(yyyy, GETDATE()) - sb.age AS VARCHAR(4)) + '-01-01' as datetime)
FROM Sheet1$BikeSebring24Hours021912_1 sb
WHERE lname = sb.lname and fname = sb.fname)
```
I hope this helps.
