Question

The following awk code is working as expected.
I want to check if the second field $2 is 0 and use “setex” command instead of default “hincrby”.

BEGIN {
    # all fields are separated by ^
    FS = "^";
}
{
    # $7 is the date and time in the form yyyy-mm-dd hh:mm:ss.
    # Split at colons to get hours minutes and seconds into a[1]
    # through a[3].  Round minutes to nearest 5.
    split($7, a, ":");
    split(gensub(/-/,"","g",$7),b,"~");
    a[2] = int(a[2]);
    printf "hincrby r:%s:%s %s:%02d:00 1\\r\\n\n zadd RequestSet %s r:%s:%s\\r\\n\n ", $1, $2, a[1], a[2], b[1], $1, $2;
}

The above code will output like this…

hincrby r:565:14718 2012-03-10~12:55:00 1\r\n zadd RequestSet 20120310 r:565:14718\r\n 

If the creativeid is 0 then the following output is expected:

hincrby r:565:0 2012-03-10~12:55:00 1\r\n zadd RequestSet 20120310 r:565:14718\r\n hincrby r:565:14718 nods 1\r\n

For all other creativeids ($2), I need another statement generated with complete date ($7)

hincrby r:565:14718 2012-03-10~12:55:00 1\r\n zadd RequestSet 20120310 r:565:14718\r\n setex xyzabc:r 172800 2012-03-10~12:59:49\r\n

In other words, I am trying to write the following PHP logic to awk

    if($creativeid !=0 ){            
        $pipe->setex($cb.':r','172800',$datetime); 
    }else{
        $pipe->hincrby("r:".$zone.":".$creativeid,'nods',1);  
    }

Update:

The following if-then-else code does not seem to work:

if $2 = 0 
printf "hincrby r:%s:%s %s:%02d:00 1\\r\\n\n zadd RequestSet %s r:%s:%s\\r\\n\n hincrby r:%s:%s nods 1\r\n", $1, $2, a[1], a[2], b[1], $1, $2, $1, $2;
else
printf "hincrby r:%s:%s %s:%02d:00 1\\r\\n\n zadd RequestSet %s r:%s:%s\\r\\n\n setex %s:r 172800 %s", $1, $2, a[1], a[2], b[1], $1, $2, $5, $7;

Answer 1

cmd = (a[2] == 0) ? "hincrby" : "setx"
print cmd    

# or 

if( a[2] == 0 ) print "hincrby"
else print "setx"   

a[2]=0 will always be true. it is just an assignment…
a[2]="anything" will be true unless it it an invalid value.

Note that if( a[2]=0 ) does change the value of a[2] …
