Keyword &Parameter Description:
index_name:
This is an undeclared identifier which can be referenced only within the FORALL statement and only as the collection subscript.
The implicit declaration of the index_name overrides any other declaration outside the loop. Therefore, another variable with similar name cannot be referenced inside the statement. Inside a FORALL statement, the index_name cannot appear in the expressions and cannot be assigned a value.
lower_bound .. upper_bound:
These are the expressions which must yield integer values and should specify a valid range of the consecutive index numbers. The expressions are computed only when the FORALL statement is initially entered.
The index is assigned a value of the lower_bound. If that value is not bigger than the value of the upper_bound, the SQL statement is executed, and then the index is incremented. If the value of the index is still not bigger than the value of upper_ bound, then the SQL statement is executed again. This procedure repeats until the value of the index is bigger than the value of the upper_bound. At that point, the FORALL statement is completed.
sql_statement:
This must be an INSERT, DELETE, & UPDATE statement that references the collection of all elements.
