If lower_bound equals upper_bound, the statements run only once. If lower_bound does not equal upper_bound when the FOR LOOP statement begins to run, then: Summary: in this tutorial, you will learn how to use the PL/SQL IF statement to either execute or skip a sequence of statements based on a specified condition.. The IF statement allows you to either execute or skip a sequence of statements, depending on a condition. The IF statement has the three forms: – IF THEN – IF THEN ELSE – IF THEN ELSIF PL/SQL IF THEN statement I'd like to create an in-memory array variable that can be used in my PL/SQL code. I can't find any collections in Oracle PL/SQL that uses pure memory, they all seem to be associated with tables. I'm looking to do something like this in my PL/SQL (C# syntax): string[] arrayvalues = new string[3] {"Matt", "Joanne", "Robert"}; Edit: Oracle: 9i This SQL statement would return the supplier_name field if the supplier_desc contained a null value.
