MYSQL :: UPDATEABLE VIEW

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 SQL Files
I am about to by the content of a site, but it is in sql files. I need to view this content and extract to make a new site from it in html format.

How do I view SQL files and extract it content? Is there any program that does it?

Can I View .frm, .MYD And .MYI Files?
At my current host, the server crashed and all data seemed to be lost. Lucky for us they had had a backup of all data which they put back on the server.

But now I get errors with some tables in phpMyAdmin where they show up as "in use" and when I view them I get the following error:

MySQL
#1033 - Incorrect information in file: *.frm
or

MySQL
#1016 - Can't open file: '*.InnoDB'. (errno: 1)

Because of the issues, they send me the *.frm, *.MYD and *.MYI files.
But am I able to view these files to see the structure or data?
And can I verify if structure or data is corrupt?

View Implementation
Anybody has implemented View for MySQL?
I think it can be done outside of Database
if query transformation approach is used.

CREATE VIEW Model
SELECT * FROM Model_CA, Brand
WHERE Model_CA.brand_rid = Brand.rid

Select brand_name from Model
where model.name = 'Test'

This can be transformed into

SELECT brand_name FROM Model_CA, Brand
WHERE Model_CA.brand_rid = Brand.rid and
Model_CA.name = 'Test'

VIEW Problem
I create the next view:

CREATE VIEW VideoDB.FindCustomer AS
SELECT id, last_name&' '&name&' '&initial AS cname, picture, birthday, birthday_already, account_type, rents, exp_date, deposit, exp_deposit, auto1, kinship1, auto2, kinship2,
auto3, kinship3, auto4, kinship4, auto5, kinship5, auto6, kinship6
FROM VideoDB.customers;

When I execute the next statement the result is 0:
select cname from videodb.findcustomer;

How can I concat the whole name.
last_name&' '&name&' '&initial AS cname

Create A View
I have a master table and five detail tables. Now I want to have an overwiew on all detail tables that are related to the master table. The problem is that there are to many repeated records.

My wish is that to have each record of detail table in a single row with master table information in the view table. I tried to reach this with joins (left or right). No chance.. Code:

Mysqldump View
I try to dump the view definition and records using the following command.

mysqldump -uroot -psecret! --databases test --tables proxy_view > mytest.txt

What all I get is the view definition without records. What is the correct method of dumping a view?

Create View
I currently have a script that I have developed on a MS SQL server. As part of it I use a VIEW to do most of my lookups. I want to transfer it to a MYSql DB, but when I try and CREATE VIEW I get the following message....

mysql> create table t (qty INT, price INT);
mysal> insert into t values (3, 50);
mysql> create view v as select qty from t;
ERROR 1064: You have an error in your SQL syntax. Check the manual that corresp
onds to your MySQL server version for the right syntax to use near 'view testv a

I am using MYSQL for Netware. I am using an example that I have found to demostrate it, but it just does not work.

Exponential View
how to store numbers in exponential view to MySQL. E.g. 4,56e-9 = 0,00000000456

I have 4,56e-9 as a variable in perl and want to store it to MySQL. Decimal as typ seems not to work. Does i realy have to convert it to 0,00000000456?

How To View All The Sp Created?
is there a way to view all the stored procedure created in mysql? a command to view all avaialble sp's?

Creating A View
I'm running the following create view:

create view letters_of_recommendation_x_organizations as select * from organizations o left join letters_of_reccomendation l on o.OrgID=l.orgid

, and getting an error "1064 (42000): You have an error in your SQL syntax; (blah blah blah) ... syntax to use near 'view junk as select * from organizations'"

I've checked the select statement - it runs ok.

I've tried a simpler select statement as well, "create view junk as select * from organizations" .

CREATING A VIEW
I am trying to creat a virtual table by using a dynamic sql. This sql needs to be reuseable on different applications. To make matters more simple to explain let's say my table is a 3 column table. The ID column is a process identifier.

ID     Integer
NAME   VARCHAR
VALUE  VARCHAR

The data will appear like this:

1      FIRSTNAME      JOE
1      LASTNAME       SMITH
2      FIRSTNAME      MARY
2      LASTNAME       JONES

I need to create a table that would take the data above and create the table like below:

ID           INTEGER
FIRSTNAME    VARCHAR
LASTNAME     VARCHAR

The data would look like this:

1      JOE            SMITH
2      MARY           JONES

Any ideas on this could work?

View Optimization
In my database I have separate four tables and from that four tables i have created one view. Each of the table contains round five lacs of records. So when view gives result it is approximately around fifteen lacs of records,

When I call that view like "select * from MyView where name='vimal'" it takes too long to give me result. And due to this one query my application server load increases by 80%. When I execute this view that time mysql Memory consumption is approximately 80% of total memory. What I can do to optimize the same? What are the other alternatives?

Create View
I must be going mad! How come I can't create a view?

mysql> create view testview as select * from userdetails;

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'view testview as select * from userdetails' at line 1

(View) Performance
I have a huge table with product data from different shops in my database. There is a flag column 'import' witch flagt products with 1 for my PHP script.

To select from one shop all product individually, work with it, and then update these product import flag to 0 in the database, seems to be the slowest way. I thougt about a view about all products of a shop with flag '1'. Code:

If Condition In View
Basically i want to add put a where condition in a view if the user variable '@org_id' is > 0. Here is some pseudo code:

CREATE VIEW view_students AS
SELECT *
FROM students
If (@org_id > 0) THEN
WHERE org_id = @org_id
END IF

I've tried lots of different approaches but i just cant figure out how to do it.

Currency View
When displaying product prices in MySQL database its only showing 17.5 instead of 17.50. Tried different things in Excel to make the view display correctly, but had no luck. Any ideas?????

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 The TimeStamp
I know you can view when a table was updated in mySQL Administrator. Is there a way in SQL to view that TimeStamp?

View With Parameters
can I put parameters into a view?

example

CREATE VIEW `dmz_sms`.`vwProva` AS
SELECT * FROM tb_sms where id=@ID;

I get error 1351.

SQL Source For A View
How do you obtain the SQL source that created a View?

I can Describe the view, but that doesn't give me the SQL that created it.

. . .

I should have searched the forums a little longer. The answer lies in the

SHOW CREATE VIEW viewName statement.

Can't Create View
I am using MySQL 5.0.0 server Alpha release. Though the manual suggests that views on tables can be created in this version but i am unable to do so.

I have a table named 'ads'.
I am creating a view named 'test' with following syntax..
create view Test as select * from ads;

Msg returned by MySql is:
[MySQL] ERROR 1064: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'view Test as select * from ads' at line 1.

VIEW In MySQL
select NO_RESPONSABLE, NOM + PRENOM as NAME from RESPONSABLE

Gives me the number of the ID, but also "0" as the result of the
concatenated NAME.

View Like In Sql2000
I have just started to look at mysql. I had to download mysql 4.0 as i had problems running mysql 4.1+.

Basically I want to know is in SQL2000 i can create views, I was told I cannot create them in mysql and was wondering how I overcome this problem.

CREATE VIEW
My servers DB is using MySQL ver4.1.10.

I need to use a query in the type CREATE VIEW

CODECREATE VIEW currentCostOfStock AS
    SELECT P.partName, P.partNo, P.manufacturer, S.vehicleType, S.years, S.price, S.stockLevel, S.price * S.stockLevel AS productCost, SUM productCost AS stockCost
    FROM Parts P, StockLedger S
    WHERE P.partNo = S.partNo ;

VIEW In MySQL
select NO_RESPONSABLE, NOM + PRENOM as NAME from RESPONSABLE

Gives me the number of the ID, but also "0" as the result of the
concatenated NAME

Create View
I'm really really stuck!
I am trying to create a view in the database but I don't know why my syntax won't work. Here is the statment...

[MYSQL]CREATE VIEW options AS SELECT customer_extras.extrasID, customer_extras.itemID, customer_quote.quoteID FROM customer_extras, customer_quote WHERE customer_extras.itemID=customer_quote.itemID;[/MYSQL]
The SQL administrater program says there's a mistake in the SQL so i tried to type it into the command line as well. Neither worked. I haven't got a clue. I have done this LOADS of times before but it won't work for me today.

I'm running the database on an xp pro machine. Latest mysql server and administrator.
Any help whatsoever would be great as I have wasted the last day looking on the internet. It's really annoying me now. I'm ready to give up

Create VIEW
I need to create a view in my mysql 4.0 and I canÂ´t, the database give me a error.
The syntax is:

CREATE VIEW LosProveedores (Nombre, Telefono, Fax, Direccion)
AS
SELECT LasEntidades.NombreIdentidad, LasEntidades.Telefono,
LasEntidades.FAX,Proveedores.Direccion
FROM LasEntidades, Proveedores
WHERE LasEntidades.IDIdentidad = Proveedores.IDIdentidad

and the errror message is:

Error 1064, you have error in your sql syntax.....Check the manual that corresponds to your MySQL server version for the right syntax to use near 'VIEW LosProveedores (Nombre, Telefono, Fax, Direccion)
AS
SELEC

Can't View Tables
I have a table located in the following directory. C:ProgramFilesMysqlDataRecipesTablesshirt.sql
The Database is Recipes and within that Database is another Database called Tables that has several tables I just used the shirt table as an example. How do I get to this table?

Create View Question
I'm trying to create a view in mySQL Query Browser. But when i create the view i get the following error,

"Definer is not fully qualified"

Here is the view itself,

CREATE VIEW `dzoic`.`POLLS_vwNumAnsPerQuestion` AS
SELECT
COUNT(poll_answers.answer_id) AS NumAnswers,
poll_questions.question_id
FROM
poll_answers
INNER JOIN poll_questions ON poll_answers.question_id = poll_questions.question_id
GROUP BY
poll_questions.question_id
Now i've played with it a little and when i add a definer (DEFINER = `dzoic`) i get the following error,

Script line: 1Definer is not fully qualified
Script line: 1You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VIEW `dzoic`.`POLLS_vwNumAnsPerQuestion` AS
SELECT
COUNT(poll_answers.an' at line 1
now i know there was an issue with a bug in mySQL versions prior 5.0.16 when creating a view. Currently the version of mySQL that i'm using is 5.0.18 and the bug was fixed by this release.

View Last Query Executed
I was wondering if it was possible to obtain the last query executed on a particular table? I have a request to log the queries executed on a particular table for audit purposes, but not sure if this is possible?

If I was hard coding the query before hand, I could obviously use this. However I am using php PDO connections following:

Quote:

$update = $db->prepare("UPDATE `table` SET {$fields} WHERE `id` = :id ");
$update->bindParam(':id', $data, PDO::PARAM_INT);
$update->execute();

The above is a simplified version, which is dynamically building the query. Essentially however I cannot obtain the whole query this way, so wondered if MySQL stored it ?

Query/View In MySql?
I am new to MySql (version 4.1). I used to use Views in Oracle that I can call them directly from my application. It seems like I can't do that with MySql. If I have a complicated query to run, I have to write the sql statement explicitly in the application each time I want to run that query. Is that true? Or am I missing something?

View Query Logs
I have a db set up and it looks like nothing went to the db because of some errors. How do I open the query log to see if anything was registered.

Show View Denied
I can create views and access them in coldfusion queries. I can not re-access them to edit or delete them.

Create View With PhpMyAdmin
I am trying to create a view between two tables. In MS SQL this is quite simple and is a standard function of the Enterprise Manager. Is there not a similar function in phpMyAdmin?

View Creation Error
I am having a problem creating a view from someone elses script

Select A_S_P * 10 as [RT QTY]

It gives me Incorrect syntax near 10

Anything you can see right away that I am missing?

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.

(Rails works fine with MySQL). hence from Rails i want to access the MySQL (Indirectly to DB2)

Creating A View For Duplicates?
I have a bit of a large database (2 million rows -- going to be around 10-12 million later), and I was wondering how to create a view that does the following:

turning THIS:
id | attribute | value
---|-----------|------
1 name joe
2 name bob
3 name paul
4 name joe
5 name paul
6 name jones
7 age 12

into THIS:

id | attribute | value | occur
---|-----------|-------|-------
1 name joe 2
2 name bob 1
3 name paul 2
6 name jones 1
7 age 12 1
the id field's values don't really matter to me except that they remain unique (the original table's id field is the primary key & auto_increments).

How To View Catalog In MySQL
How can I query mysql to view the catalog? (By the catalog I mean the
special internal database that holds the meta-information about all
other databases in the system, including descriptions of all the tables
and their fields.) I know how to do this in psql, so I imagine there
is a similar facility in mysql. FWIW, my OS is Linux.

View MYSQL TABLES VIA FTP
I have been asked to play around with the current website and make some changes etc, before i launch into it i want to get a good idea of how it is structured etc. It's written in PHP with a MYSQL backend.

I have setup a test environment on my local machine and copied the files from the existing site by grabbing them via FTP ... now everything runs via localhost except i cannot connect to mysql via phpmyadmin i played around with the settings in the config.inc.php file and it allowed me into phpmyadmin but there was no database??

How do i see the actual mysql tables or at least get a .sql file dump so i can recreate an identical test db ??

View Users Description
Is there a way to run a query to view a users description? The user will not have any priveleges for the mySQL databases. I am looking for a way when a user logs into mySQL from the web, to be able to view there description.

How To Add Auto_Increment Column Into VIEW ?
Is it possible to add in VIEW an AUTO_INCREMENT column like in MSSql ?

AUTO_INCREMENT column in table does not suite in my case..

Adding Placeholder To View
Hi. I have a really complicated query that basically sums up my whole database a few times over. To do this I use lots of views so I don't end up with one massively long query. The only drawback to this is that the lower level views cannot be dynamically filtered, at least I don't think they are. Or are they? When i put a where clause on my top level view, does that filter the lower level views according to the same criteria? If not is there anyway i can pass the lower level views a parameter?

UPDATEABLE VIEW

I am getting an error when updating a table from a view in MySQL 5. I have created a view & then reference it in my update command, by MySQL caomes back with an unknown table error. I can 'show' & 'describe' the view, so it is definately there.
