Pul How to get all fields of all objects from a sandbox in apex class?
Hi I tried teh below code to get all fields of all objects.. i'm getting too many field describes error as the field describe is above 100. Please suggest how to resolve this issue?
Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();
Map<String,Schema.SObjectField> theFieldmap;
for(Schema.SObjectType s:gd.values()){
Schema.DescribeSObjectResult r = s.getDescribe();
theFieldmap= r.fields.getMap();
}
You will get that error if the request goes beyond 100. As getDescribe method can be maximum 100.
What you can do for this requirement is instead od fetching all the fields of all the objects. You can add all your objects in a picklist. From there by selecting one object you can see all the fields in that particular object. It will reduce the no of requests.

I am not fetching all fields to show in VF page. I want to do some backend operations. Is there anyway to get all the picjklist fields alone without getting all type of fields?
Yes you can.
Check like this
fields = gd.get(objectName).getDescribe().fields.getMap();
List<SObjectField> fieldtokens = new List<SObjectField>();
fieldtokens = fields.values();
for(SObjectField fieldtoken : fieldtokens) {
DescribeFieldResult dfr = fieldtoken.getDescribe();
if(dfr.getType().name()== 'Picklist'){
fieldParentObjMap.put(dfr.getName(),dfr.getReferenceTo());
}
}
Note this is for a particular object "objectName".

I hope this will help you to get the fileds name from the Object name:
String SobjectApiName = 'Account';
Map<String, Schema.SObjectType> schemaMap = Schema.getGlobalDescribe();
Map<String, Schema.SObjectField> fieldMap = schemaMap.get(SobjectApiName).getDescribe().fields.getMap();
for(String fieldName : fieldMap.keyset() )
{
system.debug('fieldName->>'+fieldName); // This will give you the api name of the field name.
}
Thanks
