# correct DATETIME20. with wrong century?

Hello all,

I just discovered that I have a relatively large data set that was incorrectly converted from yymmdd to

DATETIME20.

Dates still kick my hinny after a year of working with sas but in any case any date that matches this needs to have the century changed from 19 to 20

``````data data.COMBOx;
set combo2;

if (year(orig_hire) < year(birth_date)) and (year > 1999) then orig_hire=

/* year(orig_hire)+100 month(orig_hire) date(orig_hire) etc*/

run;``````

I know how to parse it, I get mixed up when puting it bad together.  help please. TIA.

Rather than year, try DTYEAR to specify you're working with a date time.

Can you post some sample data please.

In general you could just use INTNX and increment it 100 years.

Oh I had not see that function before, cool.  Let me try it before going down the sample data path.   Thank you.

proc print data=combo2 (obs=10) noobs n;

var orig_hire birth_date year;

/*where year(orig_hire) < year(birth_date) and year > '1999';*/

where orig_hire < birth_date and year > '1999';

run;

orig_hire birth_date year

05SEP1900:00:00:00 05JAN1957:00:00:00 2000

16AUG1900:00:00:00 04MAR1971:00:00:00 2000

N = 10

my code:

``````data data.COMBOx;
set combo2;

/* example x=intnx('week', '17oct03'd, 6);*/
if (year(orig_hire) < year(birth_date)) and (year > 1999) then orig_hire=intnx('year', orig_hire, 100, 'S');
run;``````

Should this work?  It is bombing out.  The date is already stored as DATETIME20.  TIA.

okay the "if line" fix is:
if orig_hire < birth_date and year > '1999' and orig_hire <> . then orig_hire=intnx('dtyear', orig_hire, 100, 'S');

Is the year portion of that correct? Why are you storing it as a character...that could cause you issues.

## Re: correct DATETIME20. with wrong century?

long story

Just a hard coded year for information only per record.  I work at a School and it's easer to read than a term number.   We can dump it when we are done since each record has the term indicator.   We are stacking all the records from 50+ files once the data types are all in line and 5-10 differnt staff mebers doing this processing over the years.  Thank you for your help and attention to my coding.  -KJ
