MYSQL :: SHOW FIELDS FROM Table?

Table Fields Do Not Show Up
When creating a connection to my mysql database using dreamweaver mx, or various other programs, i can see the table names once the connection is made, but the fields do not show up with the exception of a couple of tables. I've looked over those tables several times and cannot find any differences that would cause this problem. The only program this does not seem to affect is phpmaker.

MyOLEDB Doesn't Support Commands Like SHOW FIELDS, SHOW TABLES
My code is shown below, I can select * from employees but I cannot get any data back from SHOW FIELDS, I do not receive an error, in fact, something is returned but I'm not sure what. I can execute the command:

SHOW FIELDS FROM test.employees

in the Control Center just fine, even cmd.ExecuteReader will enter reader.Read() once, something is returned but what does it look like? ......

Limiting Fields In "show Table Status"
show table status like "products";

Sometimes this is too much information and I was looking for a way in MySQL to select only the columns you wanted to see like you could do with a select.

I know I can use PHP or Perl to parse this and output only what you want but wanted to see if there was a fairly easy
way to do so in MySQL. For example if I wanted to see the
Name, Rows, and Auto_increment fields only.

Make One Field Always Show The Sum Of Other Fields?
Is it possible one of my database fields automaticly update to be the some of other fields? ex:

field 1=1
field2=1
fieldSUM=2

Now if field1 get's changed to: 3 then fieldSUM would automaticaly change to 4.

Show Rows With No Matching Fields
here is my query which probably needs some more advanced join statements:

select * from orders o, customers c, orders_styles os, styles s where o.customers_id = c.customers_id and os.orders_id = o.orders_id and os.styles_id = s.styles_id group by o.orders_id

the problem is that sometimes, because of user input, there will be no matching fields in the tables orders_styles or styles (no rows with matching orders_id exists in table orders_styles to table orders). I still want to show these rows however. Right now, as you can see it only displays rows that have matching rows in orders_styles and styles.

Fields In One Table Overwrite Fields In Another Via JOIN
I'm writing a simple web game which uses mysql to store data. The prototype works ok so far, but now I'm refactoring it to support multiple players. This means coming up with a way to store the player's current world state.

I'm thinking of doing this by having a table that defines the initial world state, and then a table containing the 'state' of anything different.

Example:
The 'objects' table looks like this:
object_id, name, room
1, Hammer, 1
2, Mirror, 1
3, Spade, 2

So, at the start, room 1 contains a hammer and a mirror, and room 2 contains a spade.
Now, if player 12 picks up the hammer then drops it in room 2, I store this override in the 'state' table

player_id, object_id, room
12, 1, 2

So. I'm trying to see if there's any kind of join syntax that would return all the objects in a room for a given player's 'session'. Obviously it could be done with temporary tables, or just comparison outside of SQL, but I keep thinking this might be possible *somehow*

SHOW TABLE
If i run "show table table_name;" i get a full description about columns,primary keys... but i dont get the constraints foreign keys.

I need to know how are my database tables associated, that is because i need to know the foreign keys from all tables.

Show Row In Table
I have a dynamic html table with one column that has text, then the other column has dynamic text pulled from a table.
Is it possible to hide rows in my table where the dynamic text comes back null? I don't even know where i would start

One Table With Many Fields Or Many Tables With Few Fields?
I need to build a database, but I'm torn between these 2 choices:

Is it better to have one table which has many fields
or
many tables which each has few fields?

Is it true that the latter is worse because it will require many join operations?
What is the limitation of the first option (one table with many fields)?

Show Table Status
I need to place the date a MySQL table was last updated into a PHP variable.
SHOW TABLE STATUS provides lots of information, including update_time, for
all of my tables. But how do I assign the value of update_time for my
"members" table into the variable $dateLastUpdated?

Show Table Status
I used "show table status " to get the database size, but how come the number of rows it shows changes each time? There's no change to the db at all. However the data length and index length remain unchanged. Why?

Show Table Insert
Is there anything like "SHOW TABLE INSERT" so I can show all the data in the db as INSERT commands? This would be useful for a db migration.

Show All Locks On A Table
[already posted to mailing.database.mysql newsgroup but not to list; sorry
for cross-post]

I found a way to do this before, but I didn't write down how I did it, so I
don't remember it now. And I've searched http://www.mysql.com/doc/ in
vain.

'Show Table Status' Speed
if anyone knows which is faster..

"SHOW TABLE STATUS LIKE '[tablename]';"

vs.

"SELECT COUNT(*) FROM [tablename];"

I'm trying to pick between these two queries (in order to get the size of the table), but want the faster of the two.i expect the table to be very large (millions of rows).

SHOW TABLE STATUS FROM DB_NAME
SHOW TABLE STATUS FROM db_name LIKE 'tbl_name';
**The command above is to show all the properties under tbl_name.

My question is, how can I get the properties in certain condition. Let's said under tbl_name contain a column name call type and it differential with A and B.
So how can I get those properties where the type='A'?

Java Mysql Show Table Status
I am using java to retrieve a resultset with "show table status" mysql
command. I am having problem reading the [name] and [engine] column.
In the metadata object it is showing as VARCHAR but when I do
getString() it is returning me the object string (e.g. "[B@1e3e7d2")and
not the actual database value. I am using Mysql 4.1 and jdbc driver
3.1. I tried getB/Clob, getBytes, getCharacterStream() and none of
them is working.

Have My Recordset Table Show Up In Random Order
I have the following code on my PHP page and my goal is to have the recordset show up in a random order each time the page is visited. I have tried a ORDER BY RAND() and come up with errors only. Is there anyway to find out what code I need to use and where I would place it in this piece of code? Code:

SHOW TABLE STATUS & The Nested SELECT Statement
The "SHOW TABLE STATUS" command seems to return a result set, just
like "SELECT * FROM SomeTable".

Therefore, since the following is valid:

SELECT * FROM (SELECT * FROM SomeTable)

I inferred that this functionality would extend to the SHOW statement:

SELECT * FROM (SHOW TABLE STATUS FROM SomeDataBase)

But such a command gives an invalid syntax error.

I want to query the data_length from a few tables, place those values
into temp variables and then run a second SQL command using those
values. Is what I'm trying to do possible?

Getting All Fields From A Table And ONLY ONE From Another One
maybe it's time to get some rest, today...

SELECT * , User_Avatar
FROM restaurantsrate, users
WHERE Card_ID =222443
AND Ratings_Deleted =0
AND Ratings_UserID = User_ID
LIMIT 0 , 30

I'm trying to get all fields from table restaurantsrate and only User_Avatar from table users, but I'm getting ALL fields from both tables? anyone can help?

How Many Fields Can A Table Have?
I'm presuming you can have as many fields as you'd like, but I'm just curious as to what the maximum recommended is. Is it ever better to split the fields over 2 tables instead of one? even though most the time if you're grabbing data from table1, you'll also be getting data from table2. The question popped into my head as I was making a "Orders" table for an online store. It has 39 fields so far and I'll probably need to add a few more (depending on what other information the client needs to know about their customer orders).

Table Fields
Is it ok to have a big table with 27 fields or should I try and split it down into smaller tables. It kind of makes sense all being in one table to me, but if that is bad design then I would break it down.

Sum 2 Fields From 2 Table
I have facing a problem to sum 2 fields from 2 table.

SELECT Table1.Stud_Number, Sum(table1.School_fee), Sum(table2.libary)
FROM Table1, Table2 WHERE Table1.Stud_Number = Table2.Stud_Number
GROUP BY Stud_Number

Db Table Fields
Is there an industry standard or best practice some of you more experienced developers could pass along concerning the number of characters I should define in my tables for a person's first name, last name, username, phone, email... and any other fields you think worth mentioning?

My Password is encrypted with sha1(), so that field is 40 characters long.

I'm looking to keep the tables as efficient as possible, so I'd like to follow some 'norms' if there are any.

Fields In Table
How do I fix this error? My tables have data.

More Than 50 Fields In A Table
I had made a table which contains more than 50 fields..
I am afraid this will hamper later ..
What i want to know ?
1>how many fields should be in a table for optimization ?
2>what should taken into consideration for future hazards in case there are more than
50 fields in table ?

SUM Of Two Foreign Table Fields
I've a project that has many timesheets (time) and many expenses (money)

I'm trying to work out the cost of the project base on a set amount per hour for timesheets plus expenses.

A project may not always have expenses.

A project has zero or many timesheets
A project has zero or many expenses

I need an SQL statement to return total time for a project and total expenses so i can do my calculations then in php. I'd prefer do this in one SQL statement.

What i have so far:

SELECT project.name, SUM(timesheet.time) AS time, SUM(expenses.amount) AS expense
FROM project, timesheet, expenses
WHERE project.id = timesheet.project_id
AND project.id = expenses.project_id
GROUP by project.id

==TABLES==

PROJECT
id PK
name

TIMESHEET
id PK
project_id FK
time

EXPENSES
id PK
project_id FK
amount
This will work fine for all projects that have both at least one expense and one timesheet. But if they are missing one then it returns no row for that project and therefore i can't display the cost.

There are other pieces of data but these are the only important ones. I can do it in two different SQL statements but i really think there has to be a way to do it in one.

Merging Two Fields In A Table!
I have used a join to bring two tables together, which works fine, but what I now have is 2 fields with dates in which I would like to order by, and at no point are these two dates overlapping, is there a way I can merge the two together, or order by both so as they overlap. My current SQL is:

SELECT * FROM tblblog
LEFT JOIN tblfilmreview
ON tblblog.blog_date = tblfilmreview.date_watched

UNION

SELECT * FROM tblblog
RIGHT JOIN tblfilmreview
ON tblblog.blog_date = tblfilmreview.date_watched

ORDER BY blog_date DESC, date_watched DESC
Thankyou for any advice you may be able to give

How Many Fields Of A Table Are Recommended?
May be a stupid question, but just want to know, how many fields/columns are recommended ? I know, it depends how many someone needs, but incase if a person needs alot of fields, then for example, is it okay to make 200 fields of a table of mysql database? or its not good to add so many fields ?

Two Similar Fields One Table
I am trying to figure how to make a single select query in one table between
two fields to see if they are similiar. I need the second one to have a
wildcard. I can easily do this with no wildcard to see if they are the same
but I can't get anything to work when it should be LIKE.

Example:

Table: test
Field1 = "testing 123"
Field2="testing"

I need something that selects that row because the word "testing" is in
both.

Fields In Table Will Not Always Update,
I'm using C#, ASP.NET and MySQL, The language is no problem (not to much) but the rest well I wonder. I have a DB table that has 5 seperate fields. A main one that
is Integer and the rest are VarChar(50). each of the 4 others are identical in setup. I can change some records and others I can't.

ID int(10),
std varchr(50),
atd varchr(50),
dtd varchr(50),
ctd varchr(50)

I update say 'atd' with new data, Date, Time and a code of 15 letters/numbers.This one takes, I change to another record and try to update ctd and it shows like it takes but when I use the Command Line it shows no updates on ctd. this is random on this also.
If I change to another record it may all work or not. Any Ideas at all?

Adding Fields To Table
Once a table has been created, can additional fields be added? What would be the syntax?

Update Fields In Table
I am trying to update multiple records,rows,fields in a table. Below is what I am placing in the sql field in phpmyadmin. It works with one update line but not more. What am I missing here?

UPDATE Products SET TitleTag='U.S. Air Force Retired Shop On-Line for Flags of the world - US, International Flags ' Where Product_ID=28;

UPDATE Products SET TitleTag='Vietnam Veterans of America Shop On-Line for Flags of the world - US, International Flags ' Where Product_ID=29;

Counting Fields In A Table
is there a way to get the field count in a table in MySql?

Maximum Fields In A Table
I have a website which runs pretty slow... I have turned on the SLOW-QUERY-LOG, and there's one table that is in the log over and over again...
It's the table which stores 99% of the user information.
This table has 61 fields, and alot of these are varChar and their set at 100 or so....
Anyways, I was curious what is the maximum amount of fields you should have in table, and in my case should I split the data between several tables and just use a complex Join statement?

93 Fields In A Single Table
I'm putting a database together for a client, he has a questionaire that comprises of 93 questions that range between yes or no's to if no why not (text and varchar fields)
I think his questionaire is ridiculous but he is the client at the end of the day.
I have been trying to decide how to put this monstrosity together and it looks as though a table with 90+ fields is going to be the result because there are no field repeats. I could design a generic "yes and no" table then populate it with the "yes no" questions linking it with a relationship but then the coding to ensure order is going to be a lot of extra work...Dwane

Show/not Show Option
I have a php page that displays pictures. The pictures comes from a mysql database. The way I am creating the recordset to dislpay is "Select * from tblehouse" . Now what I want to do is instead of selecting every picture from the database maybe create a new field that will take in the option of being checked or unchecked. Then have the query select only the "checked" to display. So my question to you guys is how would create a field that takes in a check box and what would be the sql statement to query just the checked records.

How Can I Count Non-empty Fields Of A Table
there's a form with some fields, after submitting, all non-empty inputs are in mysql table's field. how can i count how many are non-empty fields in a row of mysql table?

Prefix Table Name On Result Fields
this has to be a simple one, but it has me stumped.

I am doing a join across 10 tables. Some tables have conflicting field names (i.e. they are the same). When i access the resultset by fieldname, obviously at times I get a conflict. I cannot access the fields by the index position.

my join is in this form:

Select * FROM table1 LEFT JOIN table2 ON table1.id = table2.id2;

Now, how can I get the table names to prefix the returned columns?

I am using the creole framework for anyone who may be interesed, but have access to the RAW SQL.

Simple: Adding New Fields To A Table
i'm VERY VERY new to mysq! i have an existing table with 4 simple fields: id, lastName, firstName, and email.

i'm trying to create a registration page, and need to add a few more fields to the table: StreetAddress, City, State, and ZipCode.. i just cant remember what the sql statement is, or where to find it, and i'm not sure "what" its called - and that makes it hard to google.

i'll add the new feilds using the command line, or more likely just type the code directly into phpMyAdmin. the table name is tblCustomers

hopefully i've explained myself well enough. i know adding new fields to a table has to be about as basic as it can get.. but i cant remember how to do it!

edit:
so i did find the code i used to create the table

create table tblCustomers(
AdminID int unsigned not null auto_increment primary key,
LastName varchar(50),
FirstName varchar(50),
Email varchar(80),
AdminPW varChar(20)
);

insert into tblCustomers values
(NULL,"Smith","Bob","bob@example.com","newpass"),
(NULL,"Jones","Bill","bill@example.com","newpass"),
(NULL,"Doe","John","john@example.com","newpass"),
(NULL,"Rules","Ann","ann@example.com","newpass");

Fields In Users Db Table For Authentication
which fields do you place in your db for user authenication?

for example..:
CREATE TABLE `users` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`Username` VARCHAR(40) NOT NULL default '',
`Password` VARCHAR(40) NOT NULL default '',
`Lastlogin` datetime default NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `username` (`username`)
) ENGINE=MYISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

i wonder for some more useful fields for software logging/management people sometimes (or seldom :-)) use like:
lastip
createdon
lastlogin
active ('yes', 'no', 'banned') -

How Can I Compare Two Table Fields In One Query?
This is my problem:

"SELECT * FROM a,b WHERE a.field LIKE b.field " --> this works

"SELECT * FROM a,b WHERE a.field LIKE %b.field% " --> this works not

My Question:

Is it possible to compare two filds with the substitute symbol % if the fields are stored in different tables?

Update One Field With More Fields From Another Table
I have a select count() that seams be ignoring one clause. Data:

Table:
ID CA-Char CB-Int
1 dsfsd 6
2 dsfsd 0
3 dsfsd 1
4 sdrtt 1

SQL is:
"SELECT count(id) FROM Table WHERE CA-Char = 'dsfsd' AND CB-Int > 0"
Returns 3 - Should be 2

Listing Table Content By Fields
i've got a mysql db with a table called tshirts . Im trying to display all the shirts by category on one page in a table 2 colums wide, been told i need a do while loop ? ive looked up on php.net but didn't really make much sense to me.

while($row= mysql_fetch_array($rs) )
{
$listt .="<td width=25%><div align=center>".$row["tshirtname"]." ";
$listt .="<img src=".$row["mainpicture"]." >";
$listt .=" ".$row["tshirtdesc"]." ".$row["price"]." ";
$listt .="</td>";

the above code just displays all the shirts in a long horizontal line, thats as far as i can get, ive not got that much knowledge of php or mysql so sorry if this is a stupid question,
