Update query in SOQL

Hi,

I'm new to salesforce, APEX and SOQL. I want to know, how can we update some record using SOQL in APEX code?

You can't update records using SOQL - it is a query only language.

 

You would update record using Data Manipulation Language (DML).  E.g. to query a record and then update it you could use the following snippet:

 

 

List<Contact> conts=[select id, Email, Description from Contact where email='keir.bowden@googlemail.com' limit 1];

if (!conts.isEmpty())
{
   Contact cont=conts[0];
   cont.Description='Updated description';
   update cont;
}

 

More information on DML is available in the Apex Developer's Guide at:

Class.pato.ListOpportunities.getMyObjectOpportunities: line 354, column 1

 

The line 354 is where I have "update opp"

You can't execute DML in the Constructor (or call a method that executes DML from a Constructor)

 

If this is the controller for a VF page, you can use the action parameter on the page to directly execute addcomment, and that is allowed I believe.
