Re: compare to a blank

[Eric Merritt <cyberlync@xxxxxxxxx>]

You can compare to a blank field, you just have to
rember that if a field is blank the 400 returns a
string of blanks whose length is equal to the number
of positions in the field. So you just have to give
the compare statement a blank string whose length
equals the length of the field. So if the field is 20
positions you must compare to a string of blanks
twenty positions long.

Example:

if(record.getField("EXAMFIELD").equals("              
     "){
 //do this
}


Just as a side note if you expect a blank field try
this code so you don't have to worry about field
lengths

if(record.getField("EXAMFIELD").toString().trim().length()
== 0){
 //do this
}

its a little clunky and not as efficient as i would
like but at least you don't have to modify your code
every time a table is changed.
