How to loop through records in a block

Question

How do I get the count of records in a data block after the EXECUTE_QUERY?
If I want to manually insert or update records into the table from the datablock how do I loop thru' records in the block.?
Also for 'WHERE' clause of update statement is there anyway to tie up the rowid to the current row in the form.

Answer 1

Use get_block_property('block',QUERY_HITS).
For the second question :
Set the properties of block to be INSERT_ALLOWED=FALSE,UPDATE_ALLOWED=FALSE, next do:
go_block('block');
first_record;
set a local handler of errors
loop
next_record;
end loop;
when others then
catch the error "Record must be inserted first...'
For the third question set the DML Returning Value = Yes in property palette of the block and access the rowid as
declare
rowid_ rowid;
begin
rowid_:=:block.rowid;
end;
