1) adrsId INTEGER PRIMARY KEY If you insert a null value in "adrId," or not insert anything at all, then it will auto incremement.
2) You will not require NOT NULL, think about it. 3) I've found a really good e-book on advanced databasing, you can pick up a free copy here: http://216.197.101.104/emarketing/registration_form.cfm?pid=1&cid=1&id=5 You'll have to give them some personal information, but I really think it's worth it. Regards, PeterP -----Original Message----- From: rich coco [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 24, 2004 11:58 PM To: [EMAIL PROTECTED] Subject: [sqlite] mySQL to SQLite conversion question I see that the auto_increment keyword is not supported by SQLite: addressid bigint(20) unsigned NOT NULL auto_increment, . . . PRIMARY KEY (addressid) I understand that I have to move the 'unsigned' keyword (before 'bigint') but I do not know how to get the auto_increment semantic under SQLite. I found in the 'Datatypes in SQLite' manual page (in Section 2.0) the comment: "INTEGER PRIMARY KEY columns can be used to implement the equivalent of AUTOINCREMENT." Is the following the proper re-write to get the precise semantic I am seeking? addressid INTEGER PRIMARY KEY NOT NULL Can I then omit the subsequent "PRIMARY KEY (addressid)" line? Is "NOT NULL" no longer needed? Can someone recommend a good SQL book (I am not a DB guy)? There are so many out there and I'd like to purchase just one, so I need to get it right the first time. I found on-line manuals by DB engine providers - eg, http://www.mysql.com/doc/en/SQL_Syntax.html - but I do not know when I may be looking at specialized extentions (eg, mySQL's REGEXP and auto_increment keywords). I'd like to have my own reference. Tia, - rich -- rich coco [EMAIL PROTECTED] 781.736.1200 x165 Starbak Inc. 29 Sawyer Rd.
