ran67 Sobject Query
how to get the each field vlaue .when we are using the sobject
hi here am getting the values of an object but i want only one field value
how can get only one fileld using the soject.
and i want that field to update another string
By using the id we have got the object name and getting all the field valuees
accId = '001900000092EV2';
String prefix= accId.subString(0,3);
String objectName = objectMap.get(prefix);
system.debug('&&&&&&&'+objectName);
Map<String, Schema.SObjectField> desResult = Schema.getGlobalDescribe().get(objectName).getDescribe().Fields.getMap();
system.debug('desResult '+desResult );
List<String> fieldList = new List<String>();
system.debug('fieldList '+fieldList );
fieldList.addAll(desResult.keySet());
for(integer i =0;i<fieldList.size();i++)
System.debug(fieldList[i]);
String Query = 'SELECT ';
for(integer i =0;i<fieldList.size();i++)
Query += fieldList.get(i) + ',';
Query = Query.subString(0,Query.length()-1);
system.debug('+++++++++++'+query);
Query += ' FROM ' + objectName ;
query += ' WHERE ID= \''+ID+'\''; // modify as needed
sobject s1= Database.Query(Query);
system.debug('*&&&&&&&&&*'+s1);
you're using a describe method to get all fields, if you only want a limited selection of fields, you can use a basic soql select statement as "Select field from sobject"
to assign a field value from your result object to a string variable :
string X = s1.FIELDNAME;
This is pretty basic apex, if you're having thouble with these things, you may want to consider going through the apex workbook
