My statements are all working but I'm not sure if
things are set up correctly. I say this because at
one point the first $query failed, yet the rest of
inserts wre committed. Now I believe I need to set
autocommit to 0 , yet the query failed due to a syntax
error. Hence the rule about 0 records effected
wouldn't be the case here.
Here is what I have:
//Create these functions -
function begin()
{
mysql_query(BEGIN);
}
function commit()
{
mysql_query(COMMIT);
}
function rollback()
{
mysql_query(ROLLBACK);
}

$result = mysql_query($query); // process first query
$query = INSERT INTO secondtable...//second query
$result = mysql_query($query); // process second query
$query = INSERT INTO thirdtable//third query
$result = mysql_query($query); // process third query
then:

RE: Migrating Access Tables -- Empty Columns, Date and Time
Why don't you use the export utility in ms access to load the data into mysql. The export will create the table in the database. All you need is a dsn connection and the mysql odbc. Osvaldo Sommer -Original Message- From: Robert L Cochran [mailto:[EMAIL PROTECTED] Sent: Monday, June 28, 2004 8:21 PM To: [EMAIL PROTECTED] Subject: Migrating Access Tables -- Empty Columns, Date and Time I'm migrating a Microsoft Access 2002 (Service Pack 3) table constructed by my wife to a corresponding table in MySQL 4.0.20. Some columns in most of the 3000+ rows are empty. Some of these are contiguous empty columns. I don't know if Access considers them NULL or not, but when you export an Access row containing empty columns to a comma separated values file, the empty column will be represented by a sequence of placeholder commas. Here is a part of the first table row exported by Access: WEEKEND,,8,1,,0,,,at,,,2/12/1998 0:00:00,11/27/1998 0:00:00,,MB Based on recent experience with loading a simpler Access table, these empty columns will be imported as is by both mysqlimport and LOAD DATA LOCAL INFILE, but with warnings. I have 2 questions associated with this: 1) How do I make mysqlimport or LOAD DATA LOCAL tell me the text of each warning? By default they print a summary count of warnings but don't issue actual warning messages. The default log files show nothing. mysqlimport -v does not do it. 2) When consecutive commas (meaning at least 1 empty column, sometimes several) are seen, what does mysqlimport/LOAD DATA do to the corresponding column entrie(s)? Will it set them to NULL? Or to the default specified in the CREATE TABLE statement? Should I explicitly set these to NULL where permitted by the column type? Last of all, look at this date and time stamp exported by Access: ,2/12/1998 0:00:00, Will mysqlimport choke on this, since MySQL likes dates to be in ccyy-mm-dd format? Will I need to reformat the date with a sed script?

I think you were an even bigger help than I anticipated! If I understand correctly, I need to fix the tables I've already created. Consider three tables - Continents, Nations and States - which look something like this: CONTINENTS North America | New World | West [Hemisphere] | cna (code for North America) NATIONS United States | Washington, D.C. | us (code for the U.S.) | cna (links U.S. to North America in the Continents table) STATES Alaska | Juneau | ak (code for Alaska) | us (links Alaska to the U.S. in the Nations table) If I understand correctly, it would be smarter to create FOUR tables, that look like this: CONTINENTS North America | New World | West [Hemisphere] | cna (code for North America) NATIONS United States | Washington, D.C. | us STATES Alaska | Juneau | ak FOURTH TABLE (Links everything together) cna | us | ak (North America U.S. Alaska) cna | us | az (North America U.S. Arizona) cna | us | hi (North America U.S. Hawaii) cna | us | wy (North America U.S. Wyoming) cna | ca | ab (North America Canada Alberta) caf | ken | (NULL) (Africa Kenya) caf | tan | (NULL) (Africa Tanzania) This table would have just four fields (columns) and would begin with about 250 rows - one for each nation - with another 50 rows for the fifty U.S. states, then more rows for Canada's provinces, Mexico's states, etc. If I'm on the right track, then I could also add U.S. counties to the mix... North America United States States Counties However, since there are roughly 3,000 counties, it might be better to put them in a separate table, with rows that might look like this: cna (North America) | sd (South Dakota) | Tripp (county) cna | sd | Melette cna | sd | Sioux cna | sd | Belle Fourche Or would you advise adding the counties to the Fourth Table, which would look something like this?: cna | us | sd | Belle Fourche ccna | us | sd | Sioux cna | us | sd | Trippe cna | ca | ab | (NULL) ceu | fra | (NULL) caf | ken | (NULL) | (NULL) The top row = North America U.S. South Dakota Belle Fourche County The last row = Africa Kenya, with the rows corresponding to states/provinces and U.S. counties left NULL. I just thought of one problem, though - there are several U.S. counties that have the same name. For example, several states have a Washington County. But maybe I could just give all the counties numerical codes, or something like this - tx-1 (for Texas' first county). I wish I'd thought about this earlier.

I have an idea for another approach. If putting grasslands, forests, mountains in one cell is bad practice, then I may wind up with a table with hundreds of fields. Imagine one field filled with the names of the world's nations. Then imagine another field for tropical cloud forests, with three South American nations checked. A few northern nations are checked in the Tundra field, and so on. Obviously, there are going to be vast numbers of cells with no values at all. But what if I instead created several tables, one for each continent and listing only ecological regions associated with that continent. For example, the North America table might have just three rows, for the U.S., Canada and Mexico, with the following fields: tundra | boreal forest | eastern forests | Rocky Mountain forests | eastern grasslands | Great Plains | Sonora desert | California coastal | Pacific Northwest (there are actually a lot more.) The Africa table would have far more rows, for nations from Algeria to Zimbabwe, with fields that might look something like this: Sahara Desert | Sahel | Ethiopian mountains | tropical forest | woodlands | savanna Thus, North America and Africa will share no fields in common. However, North America and Eurasia will both share at least two fields - Tundra and Boreal Forest. So, if I create such tables for each continent, will I later be able to make a join that pulls up tundra in North America, Eurasia and Antarctica? Can I pull up the general term grasslands for all continents, or pull up Great Plains grasslands for just North America? Thanks. __ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!

RE: Inserting blob
I found a place that say MYSQL has a limit for the size off the packet in relation with blob field. They say that you need to put this in the my.cnf set-variable = max_allowed_packet=15M. With that you increase the size to 15 mb You can go and check the code in http://www.mysql-hispano.org/page.php?id=20pag=2 Osvaldo Sommer -Original Message- From: Marco Paci [mailto:[EMAIL PROTECTED] Sent: Friday, April 09, 2004 3:41 AM To: [EMAIL PROTECTED] Subject: Inserting blob Env: Win2003 Server, MySql 4.17 I've the following table CREATE TABLE TabellaTipi ( id int unsigned NOT NULL AUTO_INCREMENT, intero int, lungo bigint, decimale decimal(20,10), data datetime, stringa varchar(100), booleano tinyint unsigned, blobDati longblob, primary key (id) )TYPE=InnoDB; With a .Net application I'm developing I'm not able to insert a blob bigger than 500Kb in the table.

RE: Possible drawbacks of suggested mysql install?
Hi, we started with tha same configuration you have, and tune the MS Sql and MySQL for the memory the server (windows NT smallbusiness 4.0), and started to try our aplications against the two off them. All work really nice the two server with the same database and the same data and MySQL work faster that MS Sql. So, if you are doing it to get you people the feeling off working outside ms sql, that's a great start.

Hi there, I would like to know some professional opinions on the following: -Are there any drawbacks on installing Mysql on a windows server? Would it be possible to install it on the same server that hosts SQL server? Can they coexist properly? I do not expect too much usage of the Mysql server. We want to provide the MySQL service to our staff but might not be able to justify seperate servers.

RE: More on indexes?
Hi Eve: Indexing is use to speed up search in the tables. You can have Primary Key Index to force unique key ( Ex: Client_Cod), or normal index in columns you use to get data in an alternate way(Ex: Client_Name). If you have very little data in your tables, the speed will not notice the speed but as data grows, you start to notice the gain in the searches. You need to read a book on Relational Database.

Hi, I've been following the list to get a better grip on MySQL, and have been hearing a lot about indexing. I'm beginning to think I should have indexed some of my tables in the past. Can anyone point me in the right direction as to the purpose of indexes, why they are used, the benefits, and when one should index?
