MySQL 5.0.1 : CREATE VIEW And UNION
I don't manage to create a view from the UNION of two tables. This statement works all right : CREATE OR REPLACE VIEW myview AS SELECT 1 AS mycol UNION ALL SELECT mycol FROM mytable2; This one does not : CREATE OR REPLACE VIEW myview AS SELECT mycol FROM mytable1 UNION ALL SELECT mycol FROM mytable2; and I get the error "ERROR 1143 (42000): create view command denied to user 'root'@'localhost' for column 'mycol' in table 'myview'", although I am creating the view using the "root" account. Version used : MySQL 5.0.1 alpha snapshot (Windows binary).

I'm doing a triple join between tables which have similarly named fields...I was hoping that when using CREATE VIEW, the result would be a table with fields such as a.field, b.field, c.field...but I get an error "Duplicate column name 'field'" ...How can I get around this besides changing the name of the duplicate field in each table?

Inability To Show Create View
When I execute the command "show create view" while logged in as root I get this error: "select command denied to user 'root'@'%' for column (a table that from which the view draws part of its data)" I can select the data from the column using the standard select syntax. I can also get the data from the view itself by running it using the normal select syntax. I presume there is some corruption here. I am unable to find a way to repair a view in a manner similar to optimizing or repairing a table.

Join Tables + Create View
I have 2 tables when joined generates about 30k records. I need those results to join another table with about 174k records. I know I need to create a view right? Not too sure how to do this since I use access to do it. I will be importing to MySQL. To make it more complicated, I need to join those results to another table with about 20k records. If I join all these tables, that would generate well over the millions. This is why I need to create a View. Is my logic correct? Please help me here since I donot know too much about MySQL.

How To View Catalog In MySQL

MySQL View For A DB2 Database
I want to create a view in MYSQL, but the database/table is in a DB2 database. Is it possible ? I have heard that such a thing is possible between say ORACLE and SQL Server. Bottom line, my tables are there in DB2, and i want to create a view in MySQL database. The reason of doing this is that i'm using Ruby/RubyonRails on AIX platform, since i could not find a DB2 Driver on AIX for RAILS, i want to go for this indirect approach.

How Do I Turn On Logging To View Errors In MySQL 5
I'm a new MySQL user. Just switched over from the Bill Gates world and am joining the open source side finally. I setup a website using Joomla! 1.x with PHP5 and MySQL 5 on the backend. However when I submit a post in my forum on my new site, the page goes blank yet says it's finished loading. In the Microsoft world you can echo back to the screen errors and figure out which row, record or table was causing the error. Can you do the same using MySQL or does it have a logging feature that could help me troubleshoot and see why my posts are hanging when hitting the submit button via my browser?

MySQL View Points From Enterprise DBAs
One of our companies clients has asked us about redoing one of their highly profitable web applications in PHP and MySQL (The had an outside consultant recommend it). Their current application is built in C#.NET and SQL and is not currently clustered or load-balanced. They want to rebuild it as they have learned a lot about what they want since the original design and they know they need to make significant changes to the application to get the new features they are after and also address functionality that their current customers don't like. The company contacted the original .NET author (who also happens to be an experienced Microsoft SQL DBA) to see about redoing the applciation in PHP and MySQL and the author panned MySQL and stated that their own company had attempted to migrate one of their applications to MySQL and that from his perspectives there were many things that causes A GREAT DEAL of extra DBA overhead. I was hoping that more experienced DBAs using MySQL would be able to confirm or deny some of the Microsoft SQL DBAs claims - I have never worked with anything except MySQL and I have not used it for very long or even very often, so I am unable to successfully evaluate the claims. By no means do I want to get into 'down with Microsoft' thread here. Here are his claims:You can not centralize stored procedures for multiple databases. If you do you have to open up a whole lot of permissions that expose the system too much?The use of stored procedures and triggers is really complicated and you have to get down to a very low level of coding to understand, create or edit them, which makes the DBA's job harder and even once experienced more time-consuming?It lacks quite a few advanced features that Microsoft SQL has (he didn't cite which ones)?The upgrade path (of MySQL) is not standardizes so features that worked in version x are not guaranteed to work in version x.5 or y?There is no standardized way to backup and restore the databases and between the different methods there is a lack of compatibility. This means that backing up a MySQL database in one way - say for example MySQLdump and trying to restore it using phpMyAdmin or the MySQL administrator will not work.For those of you that have worked with different Databases do you think that MySQL is as easy to administrate and update as other Databases and even more specifically Microsoft SQL?

MySQL VIEW -> MS Word Mail Merge - Grouping Problem
Basically I am trying to create a simple invoice system that takes a query of a particular set of customer orders in the form of a VIEW (see below) and then Microsoft Word's mail merge facilities access this VIEW and then do a mail merge based upon it. The fields in each invoice are things like ShopperID, address1, address2 and other customer info as well as the products bought along with the corresponding quantity, price and amount (this essentially being quantity*price) etc. MySQL CREATE OR REPLACE VIEW invoice AS SELECT o.*, i.Product AS Product, i.price AS Price, i.qty AS qty, i.amount AS Amount FROM orders o INNER JOIN items_ordered i ON i.ShopperID = o.ShopperID WHERE o.DATE BETWEEN ��-10-01' AND ��-10-31' MS Word's mail merge connects to the database and accesses the VIEW query results just fine. The problem arises with the grouping of products (along with their associated quantity, price etc.) under each Shopper (or ShopperID to be more precise). Now, in the VIEW above I did not GROUP BY ShopperID so I used GROUP_CONCAT in conjunction with GROUP BY ShopperID to get all the products bought by a customer on the same record. MySQL CREATE OR REPLACE VIEW invoice AS SELECT o.*, GROUP_CONCAT(i.Product SEPARATOR ' ') AS Product, GROUP_CONCAT(i.price SEPARATOR ' ') AS Price, GROUP_CONCAT(i.qty SEPARATOR ' ') AS qty, GROUP_CONCAT(i.amount SEPARATOR ' ') AS Amount FROM orders o INNER JOIN items_ordered i ON i.ShopperID = o.ShopperID GROUP BY o.ShopperID HAVING o.DATE BETWEEN ��-10-01' AND ��-10-31' I thought this would work just fine but the strange thing is that MS Word displays the Product field correctly (which has been concatenated using a new line ) but it doesn't display anything for the quantity, price or amount fields. I have tried using different separators like ' / ' and ',' but the same problem occurs. Does anyone have any ideas about why it is doing this and how I can find a solution?

Using A View
I want to use a view but I'm unsure how exactly MySQL handles a view and I can't seem to find anything about it in the docs. I guess my question is: Is a view stored as a physical table or is it stored in memory or what? I'm asking because I want to make sure that if it is stored in memory that the amount of ram on my db server doesn't become an issue.

What Is A VIEW?
What is a VIEW? Why when I go to chapter 23 does it tell me how to create, alter, and drop a view, but it doesn't say what it is or what they're used for? Maybe I missed it, but is there any place in the reference where a sentence starts, "A VIEW is...". The closest I've come (looking outside of MySQL site) is a view is 'a predefined join of specified tables'. I take that to mean it is essentially a shortcut to a specific data set relationship and based on that I can see how it is useful, but why isn't this concept defined in the manual? Is it really so obvious that it doesn't require any explanation, or god forbid a demonstration of how it is used? Even more evidence that this is a stupid question is that when I google 'what is a mysql view' I get bounced back to the reference.

Is This Possible With A View?
I'm trying to cut down on the size of my database so I've changed it so that rather than implicitly setting every value in one table, I've split the data into two tables: one table (iData) contains data for the start of evey week: iData ----------------------------- 2000-01-01 Volume: 20000000 2000-01-06 Volume: 30000000 2000-01-11 Volume: 40000000 Another table (jData) contains the delta (difference) from the previous iData entry: jData ----------------------------- 2000-01-02 Volume: 1 2000-01-03 Volume: -2 2000-01-04 Volume: 1 2000-01-05 Volume: 3 2000-01-07 Volume: 2 2000-01-08 Volume: -5 2000-01-09 Volume: 6 2000-01-10 Volume: 1 2000-01-12 Volume: 2 2000-01-13 Volume: -4 2000-01-14 Volume: 4 2000-01-15 Volume: 3 Obviously this will save a lot of space as the delta is much smaller than storing the exact value (standard compression technique). So what I would like to do is create a view to automatically display all of the data as if it were all stored in one table: All Data: --------- 2000-01-01 Volume: 20000000 2000-01-02 Volume: 20000001 2000-01-03 Volume: 19999999 2000-01-04 Volume: 20000000 2000-01-05 Volume: 20000003 2000-01-06 Volume: 30000000 2000-01-07 Volume: 30000002 2000-01-08 Volume: 29999997 2000-01-09 Volume: 30000003 2000-01-10 Volume: 30000004 2000-01-11 Volume: 40000000 2000-01-12 Volume: 40000002 2000-01-13 Volume: 39999998 2000-01-14 Volume: 40000002 2000-01-15 Volume: 40000005 I know I can do this programatically, but is it possible to do this with a view? Any pointers would be much appreciated.

View Dependencies
When creating a view, it will (almost certainly) take information from one or more existing tables/views in the database. If I come to the database with no knowledge about the view (other than its name), how can I determine which underlying tables it depends on? (I can do this is PostgreSQL by performing queries against the pg_class & pg_depends internal tables but I haven't discovered any way of doing it in MySQL either with SQL queries or with the C API.

View Foreign Key
My problem is that after creating a foreign key, I cannot see in MySQL/phpMyAdmin that a column is a foreign key, here is an example of 2 tables (I wanted to create a table with users in a community an create a table=relationship which contains the information about which users know each other): CREATE TABLE `user` ( `id` double NOT NULL auto_increment, `security_code` varchar(50) NOT NULL, `active` tinyint(1) NOT NULL, PRIMARY KEY (`id`) ); CREATE TABLE `knows` ( `user_id_1` double NOT NULL, `user_id_2` double NOT NULL, KEY `benutzer_id_1` (`benutzer_id_1`), KEY `benutzer_id_2` (`benutzer_id_2`) ); Now ... after creating (using the ALTER command of MySQL) two foreign keys (linking 'knows' with 'user') in the 'knows' database (which are of course 'user_id_1' and 'user_id_2') I cannot see any changes on my tables in phpMyAdmin. Why? After using the export function of phpMyAdmin, there is nothing about the foreign keys in the generated SQL. Why? And another question concerning the relationship 'knows', would you give me some idea about how to create it in DBDesigner 4 or Workbench? There is something that I do not understand: In school we learned a lot about ERM. And in ERM you were able to define attributes for relationships (for example 'date' for table 'knows', which would inform me about when we have added the info). In DBDesigner a relationship can only be made as a connection between Entities, but without any attributes. And how would I define such recursive relationship like 'knows' (from above) in DBDesigner 4 then, so that the tool would add to the relationships foreign keys automatically and export the relationship 'knows' as a table later on?
