MYSQL :: Return A Count Of Number Of Rows Before Desired Row.

Agregate Count Return All Rows, Left Join
I have 2 tables on a lyric discussion site

Titles
   title_id
   title_name
   title_lyricist
   title_lyrics
   title_artist
   title_entered

And POSTS
   post_id
   title_id
   post_author
   post_text

I want to be able to list all the titles, and count the # of posts for each title. The problem is some titles have zero posts so my query ignores thos titles, butI syill want them returnd where Ill add a ')' for count.

This is the best i could come up with, but still only those that have posts are returned. I still want the titles that don't have a match in the posts table to be returned with a total_count of zero.

Count Number Of Rows Returned?
this is my connect and everything code:

<?php // connect to the mysql database server.
mysql_connect ($dbhost, $dbusername, $dbuserpass);
mysql_select_db($dbname) or die(mysql_error());
$query = "SELECT DISTINCT category FROM $tuttable";
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($result))
{
echo ($row['category']." | ");
}
echo count($row);
?>

Notice "echo count($row);" How do i get this to work properly. It only returns one, because there is only 1 that it is working on. I want to return the count of all the rows that fit that query.

Trying To Count The Number Of Rows In A Result Set After Query
The user fills out this form to sign up to the website, the form checks the database to see if the username has already been taken with the code:

$conn = mysql_connect("localhost:3306", "root", "********")
                                    or die ("Error With Connection");
        echo("connected<br><br>");
        $db_sel = mysql_select_db("game",$conn)
                                    or die ("Error With Database");
        $check = "select * from users where 'username' = '$username'";
        $db_sel = mysql_query($check,$conn)
                or die (mysql_error());

Using A Limit Clause, But Return The Number Of Rows Of The Query Without The Limit
I have heard of a cool feature that mysql provides a way to return the number of rows of an sql statement that contains a LIMIT as if the LIMIT had not been there.

I search the mysql manual, but could not find anything.

Return The Row Number
I have a problem. I need to rank data from highest to lowest, then return the value of what rank a certain piece of data is

For example

id value
1 20
2 80
3 60
4 120
5 10

So I need to make a query that organizes this by value

4 120
2 80
3 60
1 20
5 10

Then if my query says "for ID 1" it will return the value "4" since it is ranked 4th.

Is there any easy way to do this with a query? I am using PHP as my programming language, if theres a way of doing it with PHP can someone direct me to it?

How To Return A Row Number?
Using MySQL 5.0
CF8
DW CS3

I guess as usual this is a really simple question requiring a really simple answer but my head has a black hole at the moment so if someone could help me out I would be greatful

I have a query:

<cfquery name="rstrdt" datasource="cdsl">
SELECT * FROM players
ORDER BY winpercentage DESC,played DESC,banktotal DESC
</cfquery>

the table the query creates has many colums but 2 of the columns are 'player' & 'club

thus my question is: how would I return the row number where the player and his club are in the table, the primary key 'playerindex' identifies the player uniquely so that is of no use to me in this instance.

Return Auto_inc Number
is there a command that will will return the auto increment number of a insert at time of insert?what i've got is a table that has a client_id field that is set to auto increment. I'd like to insert a new client and with the same query return the assigned auto increment number if possable.is this something can be done or do i have to run another query to get that number?

Why Does This Count Return 1 Instead Of 0?
I don't understand why this count will return 1, when it should return 0. If I enter the resource_id 1, it will return 2, which is correct.

But if I enter any other resource_id, all of which do not exist in the 3 rows of data I have, it returns 1....

Query To Return Two Count()s
I'm trying to figure out a better way of doing this:
SELECT
(SELECT COUNT(*)
FROM GuestEvents
WHERE EventID = 1
AND EventStatus = 'y'
AND UserID = 'bob')
AS Event1,
(SELECT COUNT(*)
FROM GuestEvents
WHERE EventID = 2
AND EventStatus = 'y'
AND UserID = 'bob')
AS Event2
As you can see it's quite repetitive, I wondered if there isn't something like this which could optimise it a bit:

SELECT COUNT(EventID=1) AS Event1,
COUNT(EventID=2) AS Event2
FROM GuestEvents
WHERE EventStatus = 'y'
AND UserID = 'bob'

MySQL COUNT & Return
I'm TRYING to pull every member from a database and count how many articles they have written from one SQL Query.

"SELECT `tbl_user`.*, COUNT(`tbl_product`.`pd_author`) AS `num_articles` FROM `tbl_user`, `tbl_product` WHERE `tbl_user`.`user_statues` = 'active' AND `tbl_user`.`user_name` = `tbl_product`.`pd_author` GROUP BY `tbl_user`.`user_name` ORDER BY `tbl_user`.`user_id`"

Tables:
tbl_user & tbl_product

The Problem:
It works fine except for people with no articles but i still would like it to display there details from tbl_user.

Query Count Return Zero
I'm trying to query a database searching for everytime an event happened in the past 24 hours. I'm using a count(eventid) to add up each event during an hour time.

However, if an event didn't happen say for 2AM then 2AM isn't shown in the return.

How can I get 2AM to show as a row, but with a count of 0 (zero) ??

Here is my qeury...

select count(eventid), DATE_FORMAT(CONCAT(eventdate,' ',eventtime),'%Y%m%d%H') as hour, time_format(eventtime, '%H:00'), eventdate from event where sensorid = '2' and eventdate between '2005-01-19' and '2005-01-20' and DATE_FORMAT(CONCAT(eventdate,' ',eventtime),'%Y%m%d%H%i%s') >= '20050119150018' group by hour order by hour desc;

Regexp To Return All Number Inside A Field
does this is possible? all i just want to manipulate is the phone number in my database. i want to get the numbers inside this format text (125) 125-1268 or in this format 225.265.4649. how can i accomplish that in the query?

SELECT Count(xxx) AS Xxx Does Not Return Integer
i'm using the latest downloaded version of MySQL and am currently producing an app that is compatible with MySQL, MS Access and SQL 2000/2005, i've not really come across any problems making the app run across the 3 platforms (except for Access's wierd date syntax and MySQL's lack of a boolean field) but the followin is doing my head in:

If i run a count query such as

SELECT Count(CategoryID) AS CountCats FROM MyDownloads etc etc
CountCat = (Downloads.Fields.Item("CountCats").Value)

And then run an IF statement in my page code such as:

<% If CountCat = 0 Then .... %>

This works fine in Access and SQL as the Count value is seen as an integer, but in MySQL this chucks an error unless the code reads

<% If CountCat = "0" Then .... %>

Why is the count value not returned as an integer????? I cant understand that at all, what else could it be? I've seen another post on the forum along the same lines but with no answer to it.

This is grim as every page that uses a count needs to have an additional IF statement put on it to change the second IF statement if the database is detected as MySQL.

Find Similar Entries - Return Entry And Number
I have data in the form of random words, with some repeats. Can I write a query that will return the most frequently returned word and how many times it occured? I am just looking for a starting point...

Also, will it be possible to return the next 4 records in order. For example, if the word "me" was found 14 times and the word "toad" was found 12 times, it would return "me" and 14 and "toad" and 12?

Return Rows
Code:

select field, count(field) as count from tbl group by field
How do I return only those records that have a count of 5 or greater?

MYSQL -Top 6 -Return The Top 6 Rows
Can anybody help me to produce similar functionality to the top T-SQL command.

In sql server you can return the top 6 rows of a bigger query by using the top command.
For example

select top 6 .*
from countries

Im sure this is quite straight forward but I cant find the syntax.

View That Wont Return Existing Rows
i have a problem performing simple query over view. To make it short, so anyone
can recognize whether it is something im missing, this is the problem:

* i have created few levels of views (some of them are based on actual tables
and others are based on other created views or some mixed)
* lets say the name of the view i have problems with is "aView"
* when i perform "select * from aView" i get to see the view is correctly
populated
* when i add condition to the query above in some cases it returns ok results
but in others it returns 0 rows (which is wrong)

select * from aView where a=1, works fine
select * from aView where a=1 or b=2, works fine
select * from aVew where a=1 and b=3, returns 0 rows --- which is wrong(of
course not by itself but in my case there are rows with ok values) same goes with using only the condition on b column

a.) why wouldnt it fetch rows that are cleary in the view??
b.) is there any limitation on how high structure can we build using views

Start Transaction Blocks Rows Affected Return Value
I'm calling an update stored procedure from ASP.NET code via the .NET Connector v5.1.4.0, and Microsoft's Data Application Block v3.1.0.0

The actual code calls the procedure via the application block's ExecuteNonQuery method, which is supposed to return the 'rows affected' by the procedure code.

Everything works fine, but if I wrap the mysql code in a Start Transaction; and a Commit; then ExecuteNonQuery returns 0 rows affected, eventhough that's not true.

If I comment out the transaction statements then ExecuteNonQuery returns the actual number of rows affected.

Enable The Option Flag Return Matching Rows
I would like to know if it's possible to enable the "Return matching rows" flag with a connection string. With a dsn connection i already know how can i do this.

Desired Row From Database
I wanna retrieve the last data from database...I have a column called "id" so I did it this way..select top 1 from resource[table name] order by 'id' desc;
but it doesn't work,,,
how should I do it. I do it the same way in MS access, seems it is not working here..

Count Number Of Columns
I have a table in which all columns except the primary key are type boolean (tinyint(1) in mysql). I want to be able to compare two specific rows, referenced by their primary key, and count the number of columns in which they both have a "1". As a second search, returning the names of these columns would be helpful too.

Cant Set Desired Values In Column.. (ex. 1.jpg)
On my personal test server I have a MySQL Datatabase, and one of the fields is a type VarChar(45). For this column I have the default value set as 0.jpg.

Now, on the server provided to me on the internet I cannot select VarChar(45), and all of the ones I have tried only allow me to enter in 0 as thhe default value.

This is a problem as I need to store the filename in this column, ex 1.jpg, 2.jpg,

Query Is Not Returning Desired Results.
My query is not returning desired results.
I want to structure my query to return the Post Subject, Post Text, and Poster. Instead, it is returning the correct Post Subject, correct Post Text, but the Poster is just repeating the username from the '$_POST[username]' variable. How can I alter the query to return the correct name?

Join Tables To Count Number Of Records?
I've two tables:

responses
==========
response_id
schema_id
timestamp

answers
==========
answer_id
response_id
answer

(that's a cut down version, but will do for this question)

I need to get all the responses where there is at least one answer in the answers table. But I do not want the answer data. It's literally a quick check for an export to say "get me all the responses where there's at least one question answered". I have this: Code:

The customer buys 1 item of Product C, 2 items of Product H and 3 items of Product T.

I need to be able to count the number of PRODUCTS bought NOT the number of items. i.e. the answer here is 3.

What is the EASIEST way to do this?

Number Of Rows
Is there a quick query (without just asking to query the entire database) that will return the number of rows in a given table?
I know I can do SELECT * FROM table but I don't really care about the data, I just want to know how many entries there are.

PHP - Can't Add Rows Past A Certain Id Number (127)
I've got a table which has about 70 rows in. The rows' ids start at 1, have a large gap in the middle, then range up to 127. If I try to add a new row with an autoindexed new id, I get the following MySQL error: duplicate entry '127' for key 1.

If I add a new row with a lower id, e.g. 6, there are no issues - it works fine. If I delete row 127, or give it a lower number, I can then add a new row as normal, but then the error happens again for all subsequent rows.

Everything was working fine with the page that adds new rows until it got to 127. Is this some kind of magic number I don't know about?

Calculate Number Of Rows
From the packet data returned from a query, where in the packet data are the
bytes signifying the number of rows returned?

Restricting The Number Of Rows
I wold like to restrict the number of rows in my table. Currently I am using the mySQL ver 4.1.12a-nt

I have alter the table using this statement,

ALTER TABLE `database1`.`tabley` MAX_ROWS = 7;

But whenever I insert the 8th row, it executed successfully.

Pls explain why and how should I go about restricting the number of rows?

Table: Max Number Of Rows
In a table what is the limit to the number of rows that make it up?
Is the only limitation HardDrive space?

Maximum Number Of Rows
I am looking for information on the total number rows that can be used in an InnoDB,if there is even such a limit.I am not a DBA, so the information on mysql is a bit cryptic.

Number Of Rows In Table
Is there a query which returns the number of rows in a table without using a "SELECT..." followed by recordset.RowCount?

Retrieve Number Of Rows
I've got a large table with a lot of entries. only two fields, one's the key (which auto incs) and the other's a text field...if I want to just retrieve the number of rows in the table, what's the best way to do this?I know I could tell mysql to sort the table by the key row and then take the first one, but wouldn't this make it analyze the entire table (which would waste resources, especially considering that this table will have thousands and thousands of entries)? what's a better way to do it?

Number Of Table Rows
I have tried to answer this question by using Google but my search didn't bear any fruits, so to speak.

I am in the middle of designing my db and i have just thought that in some of my tables i think i will have 1000s of entries [rows] and if my web application with a db backend is successful it can turn into millions of rows [wishful] - so i wanted to know is there a limit in the number of rows for a table? I think not, but how will performance be effected?I am using a MySQL database, I am using a linux server not sure if this matters but microsft and i dont get along.

Actual Number Of Rows
I have a query in PHP with a LIMIT statement. Is there an easy way to get the actual number of rows (like a have no LIMIT in it)?

Limit Number Of Rows
I was wondering how can I limit the number of rows used in a table.
For example if we wanna create a table named table1 having only 7 rows.

JDBC Number Rows
After you have done a .executeQuery() and returned that to a ResultSet how do you get the number of rows returned?
I have tried using getFetchSize() but that does not help me.

Counting Number Of Rows
Can anyone come up with a novel way of counting the number of rows in a table that contain no NULL values in the columns that each row contains?
Each row contains 200+ columns, so doing a "count" on each column, and then selecting the smallest value is not very practical.

Retrive A Limit Number Of Rows
How can I make the following query :
I would like to retreive only the number of rows while sum(field1) < 20. Is this possible?
If my table have the following values :

1
4
6
8
5

It only retrieves the first 4 rows. sum(field1)=19

Limiting Number Of Rows In A Table
I'm trying to implement a basic log in a table. Instead of writing to a text
file on the server, I want to insert entries into a 'log' table. However, I
want to limit this table to only have the last 500 rows or so. How do I do
this?

Here's my pseudocode, but it seems as if there would be a better way:

logEntry($message){
insert message into table
get number of rows in table
if (numrows > 500){
delete from table where ((numrows - id) > 500)
}
}

Is that right?
