I can select all apex triggers by using
select id, name from ApexTrigger
and classes by using
select id, name from ApexClasses
but is there a way to select all objects ?
I have tried
select id, name from Objects but doesnt seem to work ?
SOQL queries run on exactly one object.
If you need to perform a full-text search across multiple objects, what you need is SOSL, the Salesforce Object Search Language. Note however that SOSL is quite different from SOQL. See the linked developer guide for more information.
