问题 Lets say I have a table and a procedure that accepts one argument of the tables rowtype: CREATE TABLE t (a NUMBER, b NUMBER); CREATE PROCEDURE p (x t%ROWTYPE) IS BEGIN NULL; END; Can I call that procedure using a rowtype literal, that is without explicitly creating a rowtype variable (or at least not explicitly listing and assigning every field of it)? The two following approaches both generate the below error: p(1, 2); p((1, 2)); PLS-00306: wrong number or types of arguments in call to 'P'

问题 I have a PL/SQL stored function which returns a table of integers: CREATE TYPE INT_TABLE IS TABLE OF INTEGER; CREATE FUNCTION f (someParam IN INTEGER) RETURN INT_TABLE IS ... I wish to use JDBC to retrieve the result of this function so that I can iterate through the integers in some way, be it a ResultSet , int[] , or whatever. The function f performs modifications to the database, so it cannot be called in a query such as SELECT f(42) FROM DUAL; . The return value exists to inform the

问题 What is the significance of execute immediate in PL/SQL when used with DML and DDL statements? Does execute immediate implicitly commit to a database like DDL statements do ?

问题 How do I get a PL/SQL program to end halfway through? I haven't been able to find any way to gracefully end the program if an exception occurs - if I handle it, it loops back into the code. Basically what I want to do is force the app not to run in certain conditions. So, I want to add something like this to the top of the program: BEGIN IF [condition] EXIT END IF [the rest of the program] END The suggested way is to throw an exception, but the block may well be an inner block - so the
