What is diff between bulk collect and forall

Answer Posted / prabhudatta barick

#"The keywords BULK COLLECT tell the SQL engine to bulk-bind output collections before returning them to the PL/SQL engine.
#You can use these keywords in the SELECT INTO, FETCH INTO, and RETURNING INTO clauses. Here is the syntax:

... BULK COLLECT INTO collection_name[, collection_name] ..."

#"The keyword FORALL instructs the PL/SQL engine to bulk-bind input collections before sending them to the SQL engine.
Although the FORALL statement contains an iteration scheme, it is not a FOR loop. Its syntax follows:

FORALL index IN lower_bound..upper_bound
sql_statement;

The index can be referenced only within the FORALL statement and only as a collection subscript.
The SQL statement must be an INSERT, UPDATE, or DELETE statement that references collection elements. And, the bounds must specify a valid range of consecutive index numbers.
The SQL engine executes the SQL statement once for each index number in the range."
