Is there any way of getting the field types dynamically by just having a String containing the name of an sObject type? (such as Contact or Account)

How would you do the following dynamically rather than put in the object type statically (in this case Contact)

Contact.sObjectType.getDescribe().fields.getMap();

 So I pretty much need to do the following

<sObject type HERE>.getDescribe().fields.getMap();

 Only having a string of the object type name Contact.

I am trying to follow the link

 Best Practice #6: Querying Large Data Sets states:

SOQL queries that return multiple records can only be used if the query results do not exceed 1,000 records, the maximum size limit of a list. If the query results return more than 1,000 records, then a SOQL query for loop must be used instead, since it can process multiple batches of records through the use of internal calls to query and queryMore.

For example, if the results are too large, the syntax below causes a runtime exception:

//A runtime exception is thrown if this query returns 1001 or more records.
Account[] accts = [SELECT id FROM account];

Instead, use a SOQL query for loop as in one of the following examples:

// Use this format for efficiency if you are executing DML statements 
// within the for loop
for (List<Account> accts : [SELECT id, name FROM account
                            WHERE name LIKE 'Acme']) {
    // Your code here
    update accts;
}

Let the Force.com platform chunk your large query results into batches of 1000 records by using this syntax where the SOQL query is in the for loop definition, and then handle the individual datasets in the for loop logic.

 --------------------------------------------------------------------------------------------------------------------

I have a test object with more than 1000 test records on it.  The test trigger is

trigger testProfileEffect on ProfileBasedTest__c (before insert)
{
for(List<ProfileBasedTest__c> pbt:[SELECT description__c FROM ProfileBasedTest__c])
{
pbt[0].description__c = 'Hello world!';
update pbt;
}


}

As a test, i am trying to update the existing record's description fields while inserting a new record & get exception:

Error: Invalid Data.
Review all error messages below to correct your data.
Apex trigger Test.testProfileEffect caused an unexpected exception, contact your administrator: Test.testProfileEffect: execution of BeforeInsert caused by: System.Exception: Too many query rows: 1001: Trigger.Test.testProfileEffect: line 3, column 38

 The exception is because of List limitation but how can I make the Best Practice #6: Querying Large Data Sets workable in this scenerio?

Thanks in advance.

Hi ,

Can anyone tell me how to get system IP address (logged in system ip) using apex. are there any DNS related classes (like java)

or any other approaches. ?

thanks for your time and help,
