If you do an alphameric comparison, you need the date on the left.

Subject: Re: SQL scrolling back to a record - REVISTED

I ended up with this as an executable query :

with tbl as (select emp,
char(tim)|| ' ' || char(dte) as clocktime,punch from timecard A) , ins as (select * from tbl where punch='IN') , outs as (select * from tbl where punch='OUT') select outs.emp, (select min(ins.clocktime) from ins where ins.emp = outs.emp and ins.clocktime > outs.clocktime) as intime, outs.clocktime as outtime from outs

The cast to an actual timestamp was problematic because of the format of the data. But, the results were a little wonky....

EMP INTIME OUTTIME
3,333 - 10:15:00 05/17/12
1,111 22:20:00 05/17/12 10:20:00 05/17/12
1,111 09:05:00 05/16/12 04:07:00 05/18/12
1,111 - 22:20:00 05/18/12
2,222 09:10:00 05/17/12 06:20:00 05/19/12
2,222 22:20:00 05/18/12 20:20:00 05/19/12

I am going to pursue the solution Charles gave me but I am still hanging on to this approach because it seems to some merit as well. Just have to sort out the particulars.

Why not use timestamp arithmetic and an embedded query?

with tbl as (select emp, timestamp(tim || ' ' || dte) as clocktime

outs as (select * from tbl where punch='OUT') select outs.emp,
outs.clocktime as outtime, (select min(ins.clocktime) from ins where
ins.emp = out.emp and ins.clocktime > outs.clocktime) as intime from
outs

I'm not sure about the arguments in that timestamp function, but the rest should work.
