Oracle SQL: The Essential Reference by David C. Kreines Following are the changes made in the 9/01 reprint. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification (xiii) In the third line: "DDL is comprised of the verbs SELECT, INSERT, UPDATE..." Has been changed to: "DML is comprised of the verbs SELECT, INSERT, UPDATE..." (9-10) The date referenced in the code samples at the bottom of page 9 and the top of page 10 did not match that mentioned in the text in the last paragraph on page 9 and the first paragraph on page 10. Therefore: "07-Jul-76" Has been changed to: "04-Jul-76" (91) First example: There is too much space before NUMBER(2) NOT NULL. This line should line up with VARCHAR2 below. Also, third line VARCHAR should be VARCHAR2. {92} The ALTER TABLESPACE syntax: ALTER TABLESPACE tablespace_name ... ... [RENAME 'filename1` TO 'filename2'] Has been changed to: ALTER TABLESPACE tablespace_name ... ... [RENAME DATAFILE 'filename1' TO 'filename2'] {166} Example for LPAD function: "X YYX LEFTLEFTRIGHT" Has been changed to: "X YYX LEFTLEFRIGHT" (170) In the first RTRIM example, the 2 at the beginning of the 2nd line is no longer in boldface.
