I know these r very basic & might be stupid 2 ask but i am just in the bigginer level...

A text string is a string of text like this: 'Hello world'.
A trigger is (usually) a piece of code that is kicked off ("triggered") by some event - usually by an insert, update or delete of a row in a table.
A cursor is a pointer to the rows from a select statement.

I suggest you get yourself an introductory book on databases to learn more.

As i told me i did refer to a SQL Html study package (Title: Teach urself SQL within 10 min) but the information what is given in that about Cursor, transacton & working with procedures is not clear.

do you have any other websites or something similar from which i can get clear idea of above.
