InnoDB or BDB?
Hi all! I am currently developing a small pos (point of sale) application. The pos will run on linux and will use java and mysql. I best guess, is that only one client will access the db during normal operations. I would like to know wich, in your opinion, should be the best option to use. The pos application should handle some degree of integrity and transaction safe, both bdb and innodb offers this two things, sooo would you mind telling me what would you use? and why? =) Also, pointng me to some url where i can compare bdb vs. innodb functionality would be greatly appreciated =) Best Regards! PS: we will most probably use 4.1 -- |...| | _ _|Victor Medina M | |\ \ \| | _ \ / \ |Linux - Java - MySQL | | \ \ \ _| | |_) / _ \ |Dpto.

Can't stratup InnoDB and BDB for Max 4.0
Dear people, I have a problem with getting InnoDB and BDB to work. I use mySQL Max 4.0. I have even made sure that the skip-BDB and skip-InnoDB lines in the configuration .xml file are commented out. But still the 'variables' list in the winmysqladmin shows haveInnoDB and haveBDB as no. I really need them as I need to use FOREIGN KEY constraints and later even, transactions in my project. I tried using FOREIGN KEY contraint for 'ON DELETE' and expectedly it did not work. Can anyone please guide me as to how to set up InnoDB and BDB to work properly?

I use mySQL Max 4.0. I have even made sure that the skip-BDB and if you are running on Windows, I think some 4.0.x versions for Windows had the error that InnoDB was not compiled into mysqld.exe or mysqld-nt.exe. You have to use mysqld-max.exe or mysqld-max-nt.exe. All these are in the bin dir of the installation. Start from the MS-DOS prompt first so that you see what it prints: C:\mysql\bin mysqld-max --console After becoming familiar with the command line startup, you can try installing mysqld-max-... as a service, as explained in the manual. skip-InnoDB lines in the configuration .xml file are commented out.

InnoDB or BdB
Heey There Folks, Well, I hope that this message gets through finallly. First I got it back from the deamon because I had send it in html format, then because of I was suspected from spamming this list. Only for not having used the words query or sql once ... well, I have now so it should come through ;) hihi I just discovered the power of transactions in databases and was wondering, which table type is better; BdB or InnoDB ? and if one is better than the other, why is it? Does BdB also support referential ingegrity as InnoDB does? Also, I was wondering what SIGNED or UNSIGNED integer are .. really don't have a clue about it :D That were some questions I was wondering about ..

RE: InnoDB or BdB
Salutations. 1: I personally use InnoDB. I think Bdb tables were the first with transactions but I don't see a lot of people talking about using them these days. Also, InnoDB is being activly developed and between sleeping, eating and coding, Heikki answers questions here! :) 2: Signed integers can have a + or an - in front of them. (The + is implied, you don't actually see it) Because that takes up a bit, it means that signed integers represent smaller numbers than unsigned. Unsigned integers can represent larger numbers. (Ok, I'm over simplifying here but work with me) There is a limit on both types as to how big of a number they can store...check the docs. =C= * * Cal Evans * The Virtual CIO * http://www.calevans.com * -Original Message- From: Wouter van Vliet [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 03, 2002 2:06 PM To: MySQL Mailinglist Subject: InnoDB or BdB Heey There Folks, Well, I hope that this message gets through finallly.

Re: InnoDB or BdB
Hello, My perception of the InnoDB vs BDB question is that although the BDB is very impressive and long standing, it does not get the same level of attention that InnoDB seems to get from the good folks at MySQL AB. If I am not mistaken, BDB does not yet offer foreign key support. I have chosen InnoDB instead of BDB and have not been disappointed so far. A signed interger is one that can accept both positive and negative values. Because storing the sign of a number uses one bit, and unsigned interger can hold a larger positve value than an unsigned integer. For example, given a 16 bit interger, the maximum value for an unsigned is 2^16, and 2^15 for the signed version.

One difference I saw was page locking versus record locking. At this point, I'm not sure that difference is significant. That's the point. As long as you are not sure about your needs, there is no reason to bother. Just start with the table type which looks nicer to you at first glance. If you should learn that it doesn't fit your needs, the other table types are only one ALTER TABLE command away.

InnoDB or BDB ON DELETE RESTRICT
If I create a table like this: CREATE TABLE depts ( ID Int AUTO_INCREMENT PRIMARY KEY, name VARCHAR(30) ) TYPE=InnoDB; I add three Records to this table. THen I create this other table: CREATE TABLE employees( ID INT AUTO_INCREMENT PRIMARY KEY, name varchar(20), dept_id INT, FOREIGN KEY (dept_id) REFERENCES depts(ID) ON DELETE RESTRICT ) TYPE=InnoDB; Then I add 2 records to this table, one with value 1 on dept_id field and the other with value 2. I want: If I attempt to delete Record with ID 1 on table depts, that MySQL don't allows me to do so, or that it updates the records at table employees to be deleted or updated to value 2 on the field dept_id. i have InnoDB and BDB working on the System, but I don't know how to do this, every time I delete from table depts, nothing happens at the records at table employees, no warnings, no nothing. Any Idea ?
