i have a requirement, where i am holding list(1000) of email address into one set, and with that i need to split them in to 100 in each sublist and make queryString need to perform sosl query.

 set<integer> nms= new set<integer>();
string str;
integer setindex=0;
for(integer i=0;i<100;i++)
{
    nms.add(i);
}

system.debug('set==>'+nms.size());

set<integer> temp= new set<integer>();
for(integer i=0;i<nms.size()/10;i++)
{

    for(integer j=0;j<30;j++ )
    { 
        str=str +string.valueOf(j)+' or ';
        setindex++;
        //sosl

    }

   if(setindex== nms.size())
       break;
   system.debug('set==>'+str);

}

can any one help me fix this issue.

Thanks

  • Why do you need to slice your array? If you're expecting less than 2000 rows, you can do it all at once.

This is a good application of the slice function that I posted a question about earlier this week.

I recommend using the version provided by Adrian or the version provided by sfdcfox.

To extend this (rather than just linking the question) you also need to divide your list into sets of 100.

You would implement this like so:

String[] yourEmailList;
for (Integer i = 0; i< 9; i++){
  Integer a = i*100;
  Integer b = (i+1)*100;
  String[] emailSublist = Utility.slice(yourEmailList,a,b);
  //perform sosl
}
