Updating current record oracle

You can use composite components wherever you can use composite variables of the same type.

Note: The components of an explicitly listed composite data structure (such as a collection constructor or record initializer) can be evaluated in any order.

If a program determines order of evaluation, then at the point where the program does so, its behavior is undefined.

after that i will press push button it will generate req numbers for that lines that time cursor should be on 35 is last record.

If a varray variable is less than 4 KB, it resides inside the table of which it is a column; otherwise, it resides outside the table but in the same tablespace.

An uninitialized varray variable is a null collection.

You must initialize it, either by making it empty or by assigning a non- Example 5-5 Nested Table of Local Type This example defines a local nested table type, declares a variable of that type (initializing it with a constructor), and defines a procedure that prints the nested table. LAST LOOP -- For first to last element DBMS_OUTPUT. PUT_LINE('---'); END; BEGIN print_names('Initial Values:'); names(3) := 'P Perez'; -- Change value of one element print_names('Current Values:'); names := Roster('A Jansen', 'B Gupta'); -- Change entire table print_names('Current Values:'); END; / CREATE OR REPLACE TYPE nt_type IS TABLE OF NUMBER; / CREATE OR REPLACE PROCEDURE print_nt (nt nt_type) AUTHID DEFINER IS i NUMBER; BEGIN i := nt. PUT_LINE('nt is empty'); ELSE WHILE i IS NOT NULL LOOP DBMS_OUTPUT. This restriction also applies to implicit comparisons.

(The procedure uses the collection methods .) The example invokes the procedure three times: After initializing the variable, after changing the value of one element, and after using a constructor to the change the values of all elements. For example, a collection variable cannot appear in a DECLARE TYPE Foursome IS VARRAY(4) OF VARCHAR2(15); -- VARRAY type team Foursome; -- varray variable TYPE Roster IS TABLE OF VARCHAR2(15); -- nested table type names Roster := Roster('Adams', 'Patel'); -- nested table variable BEGIN If two nested table variables have the same nested table type, and that nested table type does not have elements of a record type, then you can compare the two variables for equality or inequality with the relational operators equal ( dept_names1 dnames_tab := dnames_tab('Shipping','Sales','Finance','Payroll'); dept_names2 dnames_tab := dnames_tab('Sales','Finance','Shipping','Payroll'); dept_names3 dnames_tab := dnames_tab('Sales','Finance','Payroll'); BEGIN DECLARE TYPE nested_typ IS TABLE OF NUMBER; nt1 nested_typ := nested_typ(1,2,3); nt2 nested_typ := nested_typ(3,2,1); nt3 nested_typ := nested_typ(2,3,1,3); nt4 nested_typ := nested_typ(1,2,4); PROCEDURE testify ( truth BOOLEAN := NULL, quantity NUMBER := NULL ) IS BEGIN IF truth IS NOT NULL THEN DBMS_OUTPUT.
