question on getting map field values

Hi,

I have code below, I wish to know how to get value of individual fields instead of using it like values() from map.

 

CODE:

 

for(Case c:caseemlist) {
for(EmailMessage em:c.EmailMessages) {
Emailmessage message = new Emailmessage (fromname = em.fromname,subject = em.subject,textbody = em.textbody,htmlbody = em.htmlbody,toaddress = em.toaddress,
fromaddress = em.fromaddress,ccaddress = em.ccaddress,status = em.status,messagedate = em.messagedate,ParentId=oldnewCaseIdmap.get(c.id));
//emlisttoinsert.add(message);
emailMessageMap.put(em.Id, message);
}
}

Attachment[] attList = new list <Attachment>();
Attachment[] insertAttList = new list <Attachment>();
if(emailMessageMap.values().size()>0) {
insert emailMessageMap.values();

 

Example in above, i wsh to insert individual values like fromaddress, ccaddress, how do i do it, i dont want to use values().

EmailMessage eMsg = emailMessageMap.get(msgId);
eMsg.FieldName = 'some value';

You can loop through the map and insert values. Like:
for(Emailmessage message : emailMessageMap.values()) {
insert message;
}

You definitely do NOT want to loop through and insert 1 at a time... You will easily run into DML governor limits doing something like that. I think he's just trying to access specific fields in the map.

Definitely, inserting data in loop is very bad practice. As the question was how to get data from map, that I answered. Insertion should be always in the list to handle governor limit.

that doest work
EmailMessage eMsg = emailMessageMap.get(em.Id);
or
EmailMessage eMsg = emailMessageMap.get(id);
also doesnt work
em.id is very issue is, how do we get values from this map?

Did you try this?
for(Emailmessage message : emailMessageMap.values()) {
System.debug('Message:::::' + message);
}

I think you need a little more explanation of what you're actual problem is.

I PUT THIS
system.debug(emailMessageMap.values());

AND IT SHOWS THIS


13:33:15:085 USER_DEBUG [40]|DEBUG|(EmailMessage:{Status=0, ParentId=500J0000001IBG7IAO, Subject=RE: YellowBook Escalation call to sync up, HtmlBody=<html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word" xmlns:m="http://schemas.microsof

THIS STATEMENT IS BAD
insert emailMessageMap.values();

its causing heapsize to increase a lot, which is why we see the issue, i want to control that.

all i need to know is syntax of how toy pull individual field values and not all values() from map.

emailMessageMap.put(em.Id, message);
}
}

if(emailMessageMap.values().size()>0) {

for(Emailmessage message : emailMessageMap.values()) {

sieb4mesieb4me
yes, i did, that did help.
however i realized how to get individual values from map, which was doing the for loop again getting value using id and it worked.

thanks
