;

run;

 

and I wanted to pull only first record when score > 0

 

Resuling output looks like below

 

Account Score Date

A1 1 31-Jul-15

A2 2 31-Mar-14

A3 1 28-Feb-13

A4 3 31-May-16

 

When I pull the data I need to pull whole history of the account and after I need to get first record.

Thank you in advance

Hi All,

 

I have the data like below in the database. I just need to pull the first record when score is greater than zero.

 

data test;

informat date date9.;

input Account $ Score Date;

format date date9.;

cards;

A1 0 30-Apr-15

A1 0 31-May-15

A1 0 30-Jun-15

A1 1 31-Jul-15

A1 2 31-Aug-15

A1 3 30-Sep-15

A1 4 31-Oct-15

A1 5 30-Nov-15

A2 0 31-Jan-14

A2 0 28-Feb-14

A2 2 31-Mar-14

A2 3 30-Apr-14

A2 4 31-May-14

A2 5 30-Jun-14

A3 1 28-Feb-13

A3 2 31-Mar-13

A3 3 30-Apr-13

A4 0 31-Jan-16

A4 0 29-Feb-16

A4 0 31-Mar-16

A4 0 30-Apr-16

A4 3 31-May-16

;

run;

 

resulting data looks like below

Account Score Date

A1 1 31-Jul-15

A2 2 31-Mar-14

A3 1 28-Feb-13

A4 3 31-May-16

 

when I pull from the database I need to pull entire history of the acccount and after that I need to filter out. Is there any way to tell proc sql to stop at the score greater than zero.

 

Thank you in advance

Why are you fixed to SQL?
This is row type query, whoch is not a good match for SQL. Try the data step instead.

proc sort data=have;
by account date;
run;

data want;
set have;
where score ne 0;
by account date;
if first.account;
run;

 

Much, much easier in a data step.

It is not good for SQL.

data test;
informat date date9.;
input Account $ Score Date;
format date date9.;

Hi

I cannot use the data step while I am pulling from the data base because I need to pull another variables together.

Guide me please.

Thats not clear. 

 

This will work:

 

Proc sql;

select *

from have

group by account

where score >0 and date=Min(date);

quit;
