Capturing error in Exceptions Block in a PLSQL Procedure

Question

Hi,
I am creating a procedure where i need to update a table with some constraints.
i need to update atleast a million records with data from another table.
but here is the catch while updating million records, there may be some records which wont be vaild because of the constraints and cannot be updated and hence will give an error.
but in my procedure i want to write an exception block where it captures the error, ignores the error and keep coninuing the procedure and update all the remaining records instaed of getting hanged at the point of erorr.
How can i do this.
I know i can disable the constraints in the table.
but i want the constraints enabled, so that the errors are trapped and skipped and only the records that are valid are updated.
Can seomone help me write this exception block which does this function.
Thanks,
Philip.

Hi,
I used the exception bloack as u said.
i have a sample of 20 records and i know the 11th record is not valid and should be inserted in a different way from the rest 19 records.
so i ran the same query with the exceptions block.
but what happened, until 10th record everything was fine.
on the 11th record the execution went into the exceptions block and executed whatever was there in the exception block, but then the script just exited after exception block, it did not go back to fetch the remaining records from 12th unitl 20th.
How can i fix this.
