LOCKS 2008-07-18 15:04:04 -- Is to reduce concurrency 1) share lock ---it allows the other users for only reading not to insert or update or delete. 2) exclusive lock --- only one user can have the privileges of insert or update and delete of particular object --- others can only read. 3) update lock ----multiple user can read, update delete Lock le
Difference between triggers and procedures 2008-07-18 15:03:27 triggers:---------Defined with create triggerThe data dictionary contains source code in the user_triggers.Implicitly invokedCommit, save point and rollback are not allowed(TCL)procedures:----------Defined with create procedureData dictionary contains source code in user_sourceExplicitly invokedThose are allowed
What are triggers 2008-07-18 14:59:59 ---- triggers are similar to procedures, in that they are the named pl/sql blocks with declarative, executable and exception-handling sections, how ever a procedure is executed explicitly from another block via a procedure call, which can also pass arguments. ---- A trigger is executed implicitly when ever a particular event task places. And is nothing but a event. ---- The triggering event is a D
What is FORWARD DECLARATION in Packages 2008-07-18 14:58:39 PL/SQL allows for a special subprogram declaration called a forward declaration. It consists of the subprogram specification in the package body terminated by a semicolon. You can use forward declarations to do the following:• Define subprograms in logical or alphabetical order.• Define mutually recursive subprograms.(both calling each other).• Group subprograms in a packageExample of forwar Read more:Packages
What is the package 2008-07-18 14:57:44 ---- Group logically related pl/sql types, items and subprograms.package

(datatype and their total number is same).•Two subprograms if their formal parameters differ only in dat

what is REF Cursor 2008-07-18 14:47:13 To execute a multi-row query, oracle opens an unnamed work area that stores processing information, to access the information, an explicit, which names the work area or, a cursor variable, which points to the work area.where as a cursor always refers to the same query work area, a cursor variable can refer to a different work areas, cursor variable area like ‘c’ or ‘pascal’ pointers, whic Read more:Cursor

Types of cursors 2008-07-18 14:40:09 1) Implicit: declared for all DML and pl/sql statements. By default it selects one row only. 2) Explicit: Declared and named by the programmer. Use explicit cursor to individually process each row returned by a Multiple statements, is called ACTIVE SET. Allows the program
What is cursor 2008-07-18 14:31:31 A Cursor is a pointer, which works on active set, I.e. which points to only one row at a time in the context area’s ACTIVE SET. A cursor is a construct of pl/sql, used to process multiple rows using a pl/sql block.
What is Summary columns 2008-07-18 14:30:35 A summary column performs a computation on another column's data. Using the Report Wizard or Data Wizard, you can create the following summaries: sum, average, count, minimum, maximum, % total. You can also create a summary column manually in the Data Model view, and use the Property Palette to create the following additional summaries: first, last, standard deviation, variance.
